Description:
CROSS-REFERENCE TO RELATED APPLICATION(S) 
     This is a continuation of U.S. patent application Ser. No. 17/359,251, filed 25 Jun. 2021, and entitled “MODULARIZED COMPUTING AND INPUT DEVICES,” which claims priority to U.S. Provisional Patent Application No. 63/059,141, filed 30 Jul. 2020, and entitled “MODULARIZED COMPUTING AND INPUT DEVICES,” the entire disclosures of which are hereby incorporated by reference. 
    
    
     FIELD 
     The described examples relate generally to computing devices. More particularly, the present examples relate to modularized computing devices having removably attached components. 
     BACKGROUND 
     The components of computing devices, including housings for computing devices, can be designed or formed for specific purposes. Large or bulky components have traditionally been used to achieve a desired level of performance in a computing device, such as a desired amount of memory, a desired level of computing power, or a desired manner of user input. Housings for such computing devices were thus constrained to designs including relatively large or uninterrupted internal volumes. Other performance requirements for the computing devices also often limited the housings to certain form factors. 
     Recent advances in computing devices have provided for the miniaturization or reduction in size of the components, such as computing components, used to power and drive the devices, such as processors, batteries, memory, and integrated circuits. As a result, computing devices having different form-factors have been adopted to provide efficient platforms for a particular use or in a particular environment. For example, laptop and tablet computing devices are commonly used when mobility is desired, such as, reading news articles on a bus or a park bench. Alternatively, desktop computing devices are commonly desired when a user wants a larger display and/or a full-size keyboard. While computing devices have traditionally been constructed to fit the needs of a single particular use (e.g., sketching, virtual and artificial reality applications, reading social media, etc.), reconfigurable computing devices can be desirable to provide a higher quality user experience within a broad spectrum of uses and environments.

The intermediate portion can be positioned between the first and second retaining portions. Each of the first and second retaining portions can be pivotable relative to the intermediate portion. Each of the first and second retaining portions can include a first wall, a second wall, a channel at least partially defined by the first and second walls, and a pivot member. The pivot member can be rotatably attached to the intermediate portion. 
     In some examples, at least one of the first or second side walls can define a window, and at least a portion of a display interconnected to the coupling mechanism can be visible through the window. At least one of the first or second walls can include a sub-display. The pivot member can define an axis and an electronic device interconnected to the coupling mechanism can be pivotable about the axis. The coupling mechanism can include one or more magnets configured to retain an electronic device within the first retaining portion or the second retaining portion. The electronic devices can include a pair of tablet computing devices or a keyboard and a single computing device.

     DETAILED DESCRIPTION 
     The present description provides examples, and is not limiting of the scope, applicability, or configuration set forth in the claims. Thus, it will be understood that changes can be made in the function and arrangement of elements discussed, without departing from the spirit and scope of the disclosure, and various examples can omit, substitute, or add other procedures or components, as appropriate. Also, features described with respect to some examples can be combined in other examples. 
     Traditionally, computing devices can include tablet computing devices, laptop computing devices, and desktop computing devices. Tablet computing devices can resemble a display screen configured to display content to a user of the device while also being capable of receiving touch input from the user. Laptop computing devices generally assume a clamshell configuration having a display portion and a keyboard portion pivotably coupled together. Desktop computing devices generally include a distinct display (i.e., monitor), a keyboard, and a tower. While each of these types of computing devices effectively provide a quality user experience in particular environments, it can be desirable to be able to reconfigure these devices to operate effectively in a broad spectrum of applications in various environments. Thus, with traditional computing devices, users may need to rely on multiple distinct computing devices to sufficiently meet their varied needs. 
     In some examples, the computing devices described herein can be modular or reconfigurable to provide improved functionality in a variety of uses and environments. In some examples, a computing device can include a base and a hinge operably coupled to the base. The hinge can be rotatably attached to the base and can be configured to receive and retain a component or an electronic device (e.g., a display) to the base. The base can define an input surface in communication with one or more sensors to detect touch, or near touch, input at the input surface. Additionally or alternatively, the one or more sensors can detect movement of an object above the input surface, such as a gesture from the hand of a user of the computing device. 
     In some examples, one or more devices or components can be placed adjacent to the input surface, such as a keyboard positioned on the input surface. In some examples, the keyboard can have electronics or mechanisms for receiving input from a user and can communicate that input to the base. In other examples, the keyboard can include a mat having indicia which mark the boundaries of keys, but does not include any electronics or mechanisms to provide input to the input surface of the base. Instead, the one or more sensors within the base can detect input through or at the mat such that the keyboard can function as a guide or pattern for a user outlining boundaries for user input associated with specific keys of the keyboard. In some examples, one or more other input devices can be positioned at the input surface of the base, such as, one or more displays, knobs, switches, buttons, turntables, or other input devices. 
     In some examples, the computing device can include a coupling mechanism configured to interconnect multiple electronic devices or components. The coupling mechanism can include first and second retaining portions rotatably attached to an intermediate portion. Each of the retaining portions can receive an electronic device within a channel defined by one or more walls. 
     The computing devices described herein can include a variety of designs and configurations to accommodate various uses. Such computing devices can be modular and can include multiple displays, multiple input devices, or combinations thereof that can be selectively coupled to a base, a hinge, or a coupling mechanism, as desired. This arrangement can provide for a variety of different and novel configurations for utilizing the computing devices described herein. 
     These and other examples are discussed below with reference to  FIGS.  1 A- 16 C . However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting. 
       FIG.  1 A  shows an example of a computing device  100  as discussed herein, including a base  102 , a first display  104 , a second display  106 , and a keyboard  108 . One or more of the first display  104 , the second display  106 , and the keyboard  108  can be combined in various configurations with the base  102 , for example, by removably coupling therewith. In some examples, the base  102 , the first display  104 , the second display  106 , and the keyboard  108  can all be considered parts of the computing device  100 , although in some examples, the base  102  alone can be referred to as the computing device  100  and the first display  104 , the second display  106 , and the keyboard  108  can be referred to as components, input components, device, or electronic devices. 
     The base  102  can include a hinge  110  having a retaining portion  112  configured to removably retain an electronic device (e.g., the first or second displays  104 ,  106 ) to the base  102 . In some examples, the electronic device can be at least partially retained within a channel formed by the retaining portion  112 . The electronic device can be at least partially retained on or in the retaining portion  112  by a magnetic force coupling the electronic device to the retaining portion  112 . For example, the retaining portion  112  can be magnetic or can include one or more magnets or electromagnets which exert a force on a corresponding magnet or ferromagnetic material in the electronic device to retain a portion of the housing of the electronic device to the hinge  110 . The hinge  110  can be rotatably or otherwise moveably coupled to the base  102  such that an electronic device coupled to the retaining portion  112  can pivot or move relative to the base  102 . 
     The base  102  can define an input surface  114  (e.g., an upper most surface or top surface of the base  102 ). The input surface  114  can receive input from a user of the computing device  100 . For example, the base  102  can include one or more sensors, disposed within an internal volume defined by the base  102 , to detect user input at or near the input surface  114  (see  FIGS.  7 A and  7 B  and their related disclosure herein). Alternatively or additionally, an input device (e.g., the first or second displays  104 ,  106 , or the keyboard  108 ) can be positioned and/or retained on the input surface  114  to enable a user to provide input to the computing device  100 . 
     The first display  104  can be any form of display, component, or device used to display visual content to a user. For example, the first display  104  can be an LED display, an OLED display, or an LCD display. In some examples, the first display  104  can be any form of display now known in the art, or as may be developed in the future. In some examples, the first display  104  can be a touch screen display, or can have touch detecting capabilities, such as, capacitive touch, force touch, and near touch capabilities. In some examples, however, the computing device  100  can be capable of detecting a user&#39;s touch and/or a position of an appendage of the user by components other than the first display  104 . In some examples, the first display  104  can also function as a standalone computing device, such as a traditionally configured tablet computer, when not retained on the base  102 . In some examples, the first display  104  can communicate with the base  102 , and computing components in the base  102  can provide signals to the first display  104  regardless of whether the first display  104  is retained on the base  102 . 
     The second display  106  can be substantially similar to, and can include some or all of the features of the first display  104 . In some examples, the second display  106  can be any form of display, component, or device used to display visual content to a user. For example, in some examples the second display  106  can be an LED display, an OLED display, or an LCD display. In some examples, the second display  106  can be any form of display now known in the art, or as may be developed in the future. In some examples, the second display  106  can be a touch screen display, or can have touch detecting capabilities, such as, capacitive touch, force touch, and near touch capabilities. In some examples, however, the computing device  100  can be capable of detecting a user&#39;s touch and/or a position of an appendage of the user by components other than the second display  106 . 
     As described herein, and as shown in the associated figures, the first and second displays  104 ,  106  can be removably coupled to, or otherwise positioned about, the base  102  to provide various configurations of the computing device  100 . As a result, one or both of the first and second displays  104 ,  106  can be utilized to form the computing device  100 . Although a respective display (e.g., the first display  104 ) may be referred to in a particular example, another display (e.g., the second display  106 ) can be equally as applicable within the example. Moreover, while the size and aesthetic features of the second display  106  are illustrated as identical to the first display  104  in the figures, the second display  106  can differ in size, aesthetic features, and functionality from the first display  104 . 
     In some examples, the keyboard  108  can include one or more keys  116 . A user can provide input to the computing device  100  by pressing one or more of the keys  116 . Each of the keys  116  can include a respective indicia or symbol printed, etched, or otherwise provided on a surface of the key  116  to form an alphanumeric keyboard (e.g., a QWERTY type keyboard, etc.). Additionally or alternatively, one or more of the keys  116  can alter or vary operational aspects of the computing device  100 , for example, by adjusting an intensity of a backlight behind the keys  116  or by varying a magnitude of volume emitted from a speaker (not shown) housed within the first or second display  104 ,  106 , and/or the base  102 . 
     While the figures illustrate the keyboard  108  as having a particular quantity of keys  116 , each having particular sizes and shapes, the quantity of keys  116  and the particular sizes and shapes of the keys  116  can vary from one example to another. Moreover, the position of each key  116  on the keyboard  108  can be varied to accommodate other input mechanisms on the keyboard  108 , such as a track pad, touch screen, or other input surface or component. Furthermore, each key  116  can be configured to receive multiple kinds of input. In some examples, the key  116  can be actuated or receive force from a user which vertically displaces the key  116 . Additionally or alternatively, the key  116  can receive a touch input at a surface thereof to provide a track pad or touch pad utility. For example, a touch input at the surface of the key  116  can control or operate a cursor displayed at an electronic device (e.g., first and/or second displays  104 ,  106 ) operably coupled to the computing device  100 . In some examples, the key  116  can be configured to receive multi-touch input at the surface of the key  116  to enable additional operational features for a user of the computing device  100 , such as, pinch, zoom, and rotate features that enable the user to manipulate a view displayed on the electronic device. 
     In some examples, the keyboard  108  can include electrical and/or mechanical components which enable the keys  116  to be physically actuated or otherwise receive input from a user of the computing device  100 . In such examples, the keyboard  108  can include a set of key mechanisms and or a set of sensors. Each key mechanism of the set of key mechanisms can include a key cap, a support structure, and a biasing component. Each sensor of the set of sensors can be configured to detect a capacitive touch or near touch at a surface of the keyboard  108 . 
     In other examples, the keyboard  108  can be devoid of some or all electrical and mechanical components such that only the one or more sensors disposed within the base  102  detect input at the keyboard  108 . In such examples, the keyboard  108  can be a mat or a pad that provides the user with a reference or a pattern identifying the boarders and relative size of each key  116 , but the keyboard  108  does not provide any input to the base  102 . In other words, the one or more sensors within the base  102  can detect input through the keyboard  108 , which acts as a guide for the user of the computing device by outlining various input regions and key boundaries. 
       FIG.  1 B  illustrates a perspective view of the computing device  100  arranged in a first configuration, wherein the first display  104  is removably attached to the hinge  110  and the keyboard  108  is positioned on or adjacent the input surface  114 . While coupled or affixed to the base  102 , the first display  104  can be in electrical communication with one or more computing components within the base  102 , other components within the base  102  (e.g., a power source), the keyboard  108 , an accessory device (e.g., a stand-alone track pad), or a combination thereof. For example, the retaining portion  112  can form an electrically conductive pathway configured to receive and/or transmit data and/or power from the first display  104 , and to distribute the data to one or more of the components described above. Likewise, the retaining portion  112  can be configured to transfer or deliver data and/or power to the first display  104  from one or more of the components described above. In some examples, the first display  104  can wirelessly transmit and/or receive data and/or power from the base  102 . In some examples, the base  102  and/or first display  104  can contain wireless charging components, such as inductive charging components. In some examples, the base  102  and/or the display  104  can include one or more wireless antennas, such as WIFI, Bluetooth, cellular, LTE, or any other form of wireless antenna. 
     Like the first display  104 , while coupled or affixed to the input surface  114 , the keyboard  108  can also be placed in wireless and/or electrical communication with one or more computing components within the base  102 , other components within the base  102  (e.g., a power source), the first display  104 , an ancillary device (e.g., a stand-alone track pad), or a combination thereof. For example, the keyboard  108  can wirelessly transfer data to the base  102  or other component as a result of user input received at the keyboard  108  (e.g., actuation of a key  116 ). The keyboard  108  can be aligned and affixed to the base  102 , for example, using one or more magnets within the base  102  and/or the keyboard  108 . In some examples, the base  102  can form or define a raised portion  118  that can act as a datum for aligning the keyboard  108  relative to the input surface  114 . Additionally, or alternatively, a bottom surface (e.g., a surface of the keyboard  108  which interfaces with the base  102  and/or the input surface  114 ) can have a relatively high coefficient of friction to limit or prevent the keyboard  108  from sliding or moving on the base  102  while receiving input. For example, a surface of the keyboard  108  and/or the input surface  114  can include a coating or material having a relatively high coefficient of friction, such as a polymeric or rubberized material. 
       FIG.  1 C  illustrates a perspective view of the computing device  100  arranged in a second configuration, wherein the first display  104  is removably attached to the hinge  110  and the second display  106  is positioned adjacent the input surface  114 . Again, while coupled or affixed to the base  102 , the first display  104  can be placed in electrical and/or wireless communication with one or more computing components within the base  102 , other components within the base  102  (e.g., a power source), the second display  106 , an ancillary device (e.g., the keyboard  108 ), or a combination thereof. For example, the retaining portion  112  can form an electrically conductive pathway configured to receive data and/or power from the first display  104  and distribute the data to one or more of the components described above. Likewise, the retaining portion  112  can be configured to transfer or deliver data and/or power to the first display  104  from one or more of the components described above. 
     Like the first display  104 , while coupled or affixed to the input surface  114 , the second display  106  can also be placed in electrical communication with one or more computing components within the base  102 , other components within the base  102  (e.g., a power source), the first display  104 , an ancillary device (e.g., the keyboard  108 ), or a combination thereof. For example, the second display  106  can wirelessly transfer data and/or power to the base  102  or other component as a result of user input received at the second display  106  (e.g., user input at a surface of the second display  106  configured to receive capacitive touch input). The second display  106  can be aligned and affixed to the base  102 , for example, using one or more magnets within the base  102  and/or the second display  106 . In some examples, the raised portion  118  of the base  102  can act as a datum for aligning the second display  106  relative to the input surface  114 . Additionally, or alternatively, a bottom surface (e.g., a surface of the second display  106  which interfaces with the base  102 ) can have a relatively high coefficient of friction to limit or prevent the second display  106  from sliding or moving on the base  102 . 
       FIG.  2 A  shows the computing device  100  of  FIG.  1 A  in a closed state arranged in a third configuration, wherein the second display  106  is positioned on a housing  120  of the first display  104  such that a display screen  122  of the second display  106  is visible or otherwise accessible to a user of the computing device  100 . As illustrated in  FIG.  2 A , the keyboard  108  can be positioned between the base  102  and the first display  104  while the computing device  100  is in a closed state. In some examples, while the computing device  100  is in a closed state and the keyboard  108  is positioned between the base  102  and the first display  104 , the first display  104  and/or the keyboard  108  can be deactivated or non-functioning to prevent unintentional or accidental input to the computing device  100  from the first display  104  and the keyboard  108 . If the computing device  100  is opened by a user to an opened state, the second display  106  can be deactivated or rendered inoperable while the first display  104  and/or keyboard  108  can be activated or rendered operable. 
     In this configuration, the second display  106  can function as the primary display for the computing device  100  and receive user input at the display screen  122 . In some examples, the computing device  100  can function as a tablet computing device in this configuration, wherein the user interacts and interfaces with the second display  106 . The second display  106  can be removably affixed to the first display  104 , for example, by one or more magnets positioned within the first display  104  and/or the second display  106 . In some examples, the housing  120  of the first display can include metal or a magnet that interacts with one or more magnets within the second display  106  to removably couple the second display  106  to the housing  120  of the first display  104 . Similarly, a housing  124  of the second display  106  can include metal or magnets that interact with one or more magnets within the first display  104  to removably couple the second display  106  to the first display  104 . 
       FIG.  2 B  shows the computing device  100  of  FIG.  1 A  in a closed state arranged in a fourth configuration, wherein the second display  106  is positioned on the housing  120  of the first display  104  such that the display screen  122  of the second display  106  is nonvisible or otherwise facing downward and toward the first display  104 . Like the configuration illustrated in  FIG.  2 A , the keyboard  108  can be positioned between the base  102  and the first display  104  while the computing device  100  is in a closed state. Again, while the computing device  100  is in a closed state and the keyboard  108  is positioned between the base  102  and the first display  104 , the first display  104  and/or the keyboard  108  can be deactivated or non-functioning to prevent unintentional or accidental input to the computing device  100  from the first display  104  and the keyboard  108 . 
     If the computing device  100  is opened by a user to an open state, the first display  104  and/or keyboard  108  can be activated or rendered operable. In this configuration, the second display  106  can be inoperable or deactivated to no longer output content to a user or receive input from a user. This can be beneficial, for example, when transporting the computing device  100  and input at the computing device  100  is undesirable. Like the configuration shown in  FIG.  2 A , the second display  106  can be removably affixed to the first display  104  in this configuration. For example, the second display  106  can be removably affixed to the first display  104  by one or more magnets positioned within the first display  104  and/or the second display  106 . 
       FIG.  2 C  shows the computing device  100  of  FIG.  1 A  in a closed state arranged in a fifth configuration, wherein the keyboard  108  is positioned on the housing  120  of the first display  104 . As illustrated in  FIG.  2 C , the second display  106  can be positioned between the base  102  and the first display  104  while the computing device  100  is in a closed state. While the computing device  100  is in a closed state and the second display  106  is positioned between the base  102  and the first display  104 , the first display  104  and/or the second display  106  can be deactivated or non-functioning to prevent unintentional or accidental input to the computing device  100  from the first and second displays  104 ,  106 . By positioning the second display  106  between the base  102  and the first display  104 , the second display  106  can be protected or shielded from potential damage when transporting the computing device  100 . Moreover, the first display  104  can be protected or shielded from damage by the keyboard  108 . 
     If the computing device  100  is opened by a user to an open state, the first display  104  and/or the second display  106  can be activated or rendered operable. The keyboard  108  can be removably affixed to the first display  104 , for example, by one or more magnets positioned within the first display  104  and/or the keyboard  108 . In some examples, the housing  120  of the first display can include metal that interacts with one or more magnets within the keyboard  108  to removably couple the keyboard  108  to the housing  120  of the first display  104 . 
     In some examples, the component positioned on the first display  104  (e.g., the second display in  FIGS.  2 A and  2 B , or the keyboard  108  in  FIG.  2 C ) can remain affixed to the first display  104  while the computing device  100  is opened by a user, and can remain affixed while the computing device  100  is left in an open state. Although reference has been made to the first and second displays  104 ,  106  in particular positions within the computing device  100 , the first display  104  can be substituted for the second display  106 , and vice versa. For example, the relative positions and functions of the first and second displays of  FIG.  2 A  can be swapped such that the first display  104  is positioned outside of the closed computing device  100 . 
     Various examples of computing devices having one or more electronic devices attached thereto are described below with reference to  FIGS.  3 A- 4 C .  FIG.  3 A  shows an example of a computing device  200  as discussed herein, including a coupling mechanism  202 , a first display  204 , a second display  206  (see  FIG.  3 C ), and a keyboard  208 . One or more of the first display  204 , the second display  206 , and the keyboard  208  can be combined in various configurations with the coupling mechanism  202  to form the computing device  200 . In some examples, the computing device  200  and the first display  204 , the second display  206 , and the keyboard  208  can include some or all of the features of the other computing devices, displays, and keyboards discussed herein. 
     The coupling mechanism  202  can include first and second retaining portions  210 ,  212  pivotably coupled to an intermediate portion  214  such that displays or keyboards coupled to the first or second retaining portion  210 ,  212  can pivot relative to the intermediate portion  214 . Each of the first and second retaining portions  210 ,  212  can be configured to removably retain an electronic device (e.g., the first or second displays  204 ,  206 , or the keyboard  208 ) or other objects to the coupling mechanism  202 . In some examples, the first retaining portion  210  can define or form a first channel  216 , and the second retaining portion  212  can define or form a second channel  218 . Either the first display  204 , the second display  206 , the keyboard  208 , or another object can be removably retained within one of the first or second channels  216 ,  218  or otherwise removably attached to the coupling mechanism  202 . For example, the first retaining portion  210  can be magnetic or can include one or more magnets or electromagnets which retain a portion of the housing of the electronic device to the first retaining portion  210 . 
     In some examples, the intermediate portion  214  can form an elongate member  220  having first and second recesses, formed therein. In some examples, the elongate member  220  can form an internal volume. One or more computing components, sensors, other components, or a combination thereof can be disposed within the internal volume of the elongate member  220 . The first recess can receive at least a portion of the first pivot member while the second recess can receive at least a portion of a second pivot member. The coupling mechanism  202  will be discussed in further detail herein with reference to  FIGS.  8 A through  8 D . 
       FIG.  3 B  illustrates a perspective view of the computing device  200  arranged in a first configuration, wherein the first display  204  is removably coupled to the first retaining portion  210  and the keyboard  208  is removably coupled to the second retaining portion  212 . In this configuration, the computing device  200  can substantially resemble and/or function as a traditional laptop computing device. 
     While coupled or affixed to the coupling mechanism  202 , the first display  204  can be placed in wireless and/or electrical communication with one or more computing components within the coupling mechanism  202  (e.g., a processor, memory, etc.), other components within the coupling mechanism  202  (e.g., a power source), the keyboard  208 , or a combination thereof. For example, the first retaining portion  210  can form an electrically conductive pathway configured to receive data and/or power from the first display  204  and distribute the data and/or power to one or more of the components described above. Likewise, the first retaining portion  210  can be configured to transfer or deliver data and/or power to the first display  204  from one or more of the components described above. As such, the first and second retaining portions  210 ,  212  and the intermediate portion  214  can form a wireless and/or conductive pathway to electrically couple the first display  204  to the keyboard  208 . 
       FIG.  3 C  illustrates a perspective view of the computing device  200  arranged in a second configuration, wherein the first display  204  is removably coupled to the first retaining portion  210 , and the second display  206  is removably coupled to the second retaining portion  212 . In this configuration, the second display  206  can function as a virtual keyboard, a track pad, a secondary display, another form of input component, or a combination thereof. 
     While coupled or affixed to the coupling mechanism  202 , the second display  206  can be placed in electrical and/or wireless communication with one or more computing components within the coupling mechanism  202  (e.g., a processor, memory, etc.), other components within the coupling mechanism  202  (e.g., a power source), the first display  204 , or a combination thereof. For example, the second retaining portion  212  can form an electrically conductive pathway configured to receive data and/or power from the second display  204  and distribute the data and/or power to one or more of the components described above. Likewise, the second retaining portion  212  can be configured to transfer or deliver data and/or power to the second display  206  from one or more of the components described above. As such, the first and second retaining portions  210 ,  212  and the intermediate portion  214  can form a conductive pathway to electrically couple the first display  204  to the second display  206 . 
       FIG.  4 A  shows the configuration of the computing device  200  of  FIG.  3 B  in a closed state having the first and second retaining portions  210 ,  212  rotated relative to the intermediate portion  214  such that the first display  204  is positioned adjacent the keyboard  208 . While in the closed state, the first display  204  and the keyboard  208  can be inoperable or deactivated to prevent accidental or unwanted operation of the computing device  200 . 
     In some examples, the first and second retaining portions  210 ,  212  can be pivotally coupled to the intermediate portion  214  such that the first display  204  and keyboard  208  are substantially parallel to one another while the computing device  200  is in a closed state. The computing device  200  can be biased to remain in a closed state while the first display  204  and the keyboard  208  are substantially parallel. For example, the coupling mechanism  202  can include a biasing member (e.g., a spring, not shown) configured to bias the first retaining portion  210  in a particular position relative to the second retaining portion  212 . Alternatively or additionally, one or more magnets can be positioned within the first display  204  and keyboard  208  such that the magnets bias the keyboard  208  to contact the first display  204  while they are in proximity to one another (i.e., when the computing device  200  is in the closed state). 
       FIG.  4 B  shows the configuration of the computing device  200  of  FIG.  3 C  in a closed state having the first and second retaining portions  210 ,  212  rotated relative to the intermediate portion  214  such that the first display  204  is positioned adjacent the second display  206 . While in the closed state, the first display  204  and the second display  206  can be inoperable or deactivated to prevent accidental or unwanted operation of the computing device  200 . 
     In some examples, the first and second retaining portions  210 ,  212  can be pivotally coupled to the intermediate portion  214  such that the first display  204  and the second display  206  are substantially parallel to one another while the computing device  200  is in a closed state. The computing device  200  can be biased to remain in a closed state while the first display  204  and the second display are substantially parallel. For example, the coupling mechanism  202  can include a biasing member (e.g., a spring) configured to bias the first retaining portion  210  in a particular position relative to the second retaining portion  212 . Alternatively or additionally, one or more magnets can be positioned within the first display  204  and the second display  206  such that the magnets bias the second display  206  to contact the first display  204  while they are in proximity to one another (i.e., when the computing device  200  is in the closed state). 
       FIG.  4 C  shows the computing device of  FIG.  4 A  in a closed state and in another configuration, wherein the first display  204  is positioned within the first retaining portion  210  such that a display screen  226  of the first display  204  is oriented away from the keyboard  208 . In some examples, the computing device  200  can function as a tablet computing device in this configuration, wherein the user interacts and interfaces with the first display  204 . 
     As illustrated by  FIGS.  4 A and  4 C , the first display  204  can be received and retained within the first retaining portion  210  in multiple orientations. For example, as shown in  FIG.  4 A , the first display  204  can be oriented within the first retaining portion  210  such that the display screen  226  is oriented toward the keyboard  208 . However, the first display  204  can be detached or removed from the first retaining portion  210 , flipped or rotated, and reattached within the first retaining portion  210  such that the display screen  226  is oriented away from the keyboard  208 , as shown in  FIG.  4 C . Thus, the computing device  200  is modular or otherwise configured to permit removal and reattachment of a plurality of components (e.g., the first display  204 , the second display  206 , the keyboard  208 , other objects, or combinations thereof) in various orientations relative to the first and second retaining portions  210 ,  212 . 
     Various examples of computing devices having a base configured to couple to one or more electronic devices are described below with reference to  FIGS.  5 A- 7 B .  FIG.  5 A- 5 C  illustrate various views of an example of a computing device  300  including a base  302  and a display  304 . In some examples, the computing device  300  can be substantially similar to any of the computing devices described herein, such as the computing device  100  depicted in  FIGS.  1 A- 2 C . For example, the computing device  300  can include a second display and keyboard (not shown) configured to removably couple to the base  302 . Moreover, the display  304  can be removable from a hinge  306  of the base  302 . 
     Like other examples described herein, the base  302  can define an input surface  308  that receives input from a user of the computing device  300 . In some examples, the input surface  308  can detect touch input at one or more locations on the input surface  308  that correspond to a particular response by the computing device  300 . For example, a keyboard can be projected, etched, or otherwise defined on the input surface  308 , and the user input (e.g., touch input or gesture input) at a location on the input surface  308  can cause the computing device  300  to display an indicia, such as, a letter, symbol, or other alphanumeric value which corresponds with the location, or to perform any other desired action. 
     Additionally or alternatively, at least a portion of the input surface  308  can be configured to operate as a track pad and thereby control or operate a cursor displayed at the display  304 . As such, the input surface  308  can detect a touch, near touch, and/or force input to determine a direction in which a cursor or other indicator, displayed at the display  304 , can move (e.g., in response to a user input signal associated with the cursor movement). Thus, multiple discrete touch and/or force inputs can be compared across the input surface  308  to determine a direction of motion of a user&#39;s finger across the input surface  308 . A user input signal can be generated that instructs the computing device  300  to display the cursor in a new position based on the determined direction of motion, or to perform any other desired action. The portion of the input surface  308  that operates as a track pad can vary, for example, on a program or software being run on the computing device  300 . In some examples, the input surface  308  can function as a track pad and keyboard simultaneously, for example, by detecting touch input at a location as an input of the keyboard and detecting a sliding touch input as an input of the track pad. 
     The base  302  can form or define a raised portion  310  having one or more sensors, computing components, or combinations thereof. In some examples, the raised portion  310  can include a top wall  312  and a side wall  314 . The side wall  314  can be substantially perpendicular to the top wall  312 . In some examples, the side wall  314  can define a datum or alignment surface at which other devices (e.g., a second display, keyboard, etc.) can be positioned to align the other devices on the input surface  308 . Like the input surface  308 , the top wall  312  of the raised portion  310  can be configured to receive input from a user. For example, the top wall  312  can operate as a dynamic input/output device or other input mechanism. Non-limiting examples of dynamic input/output devices are described U.S. Pat. No. 9,927,895 issued Mar. 27, 2018, the disclosure of which is hereby incorporated by reference in its entirety. 
     The base  302  can include any material that permits the functionality and uses described herein. In some examples, the base  302  can include a metal, a metal alloy, a glass, a ceramic, a polymer, or combinations thereof. For example, the base  302  can include aluminum and glass, wherein the glass forms the input surface  308  and the aluminum forms the rest of the structure of the base  302 . Forming the input surface  308  of glass, polymer, or ceramic can permit radio frequency (RF) transmission and reception through the input surface  308 . For example, a transceiver or antenna positioned within the base  302  can receive and send RF signals through the input surface  308 . In some examples, a relatively small portion of the base  302  can be made of an RF transparent material, such as, the raised portion  310  to provide wireless communication to other devices (e.g., IEEE 802: Bluetooth and Wi-Fi wireless networking technologies). 
     In some examples, the input surface  308  can be a smooth planar surface devoid of ridges, recesses, or formations on the input surface  308 . For example, the input surface  308  can a smooth surface on which input regions are projected or otherwise displayed as a reference for the user of the computing device  300 . For example, a projector can be positioned in the raised portion  310  and configured to project an image on the input surface  308  or elsewhere. In other examples, the input surface  308  can be a textured planar surface having ridges, recesses, and/or other formations thereon. For examples, the input surface  308  can be etched or machined to define key boundaries of a QWERTY keyboard discernable by a user of the computing device  300 . 
       FIG.  6    shows an exploded view of the base  302  including the hinge  306 , an upper portion  316  of the base  302 , a plurality of sensors  318 ,  320 , computing components  322 , a substrate  324 , and a lower portion  326  of the base  302 . As illustrated in  FIG.  6   , the base  302  can form a body around which other components can be positioned. For example, the base  302  can define an internal volume or cavity between the upper portion  316  and the lower portion  326 . One or more of the plurality of sensors  318 ,  320 , the computing components  322 , the substrate  324 , or a combination thereof can be disposed within the internal volume (see internal volume  344  in  FIGS.  7 A and  7 B ). 
     The hinge  306  can be pivotally coupled to the base  302 , for example, a portion of the hinge  306  can pivotally couple within a recess  328  formed within the base  302 . For example, a pivot member (see  FIGS.  7 A and  7 B ) of the hinge  306  can be positioned within the recess  328 . The hinge  306  can pivotally or rotatably couple to the base  302  by any mechanism now known in the art or as may be developed in the future. For example, the hinge  306  can be pinned to the base  302  to enable the hinge  306  to rotate relative to the base  302 . 
     The retaining portion  330  can include a first wall  332  and a second wall  334  that define a channel  336  (see  FIGS.  7 A and  7 B ). A device, such as a display, can be at least partially positioned between the first and second walls  332 ,  334  and within the channel  336  when the device is removably affixed within the retaining portion  330 . In some examples, the first wall  332  can have a first height H 1  while the second wall  334  has a second height H 2  (see  FIGS.  7 A and  7 B ). The first height H 1  can be different from the second height H 2 . For example, the first height H 1  can be greater or taller than the second height H 2  in some examples. Although the first height H 1  is depicted as greater or taller that the second height H 2  in  FIGS.  7 A and  7 B , in other examples, the second height H 2  can be equivalent to the first height H 1  or less than the first height H 1 . 
     In some examples, the input surface  308  can define the entirety of the upper portion  316  of the base  302 . In other examples, the input surface  308  can define a portion of the upper portion  316 . The first plurality of sensors  318  can be disposed within the internal volume  344  and below the raised portion  310  to detect touch input at the base  302 . For example, the first plurality of sensors  318  can detect touch input at the raised portion  310 . Additionally, or alternatively, the first plurality of sensors  318  can detect a location at which the input surface  308  receives input. For example, the first plurality of sensors  318  can be configured to emit light or another form of energy that rebounds or reflects from the user&#39;s finger or hand to determine a distance from the sensor  318  that the user touches the input surface  308 . The sensor  318  (or a processing unit  338  communicatively coupled to the sensor  318 ) can then determine the location at which the input surface  308  was touched based on the determined distance and implement a response to the input. 
     The second plurality of sensors  320  can be disposed within the internal volume  344  and below the input surface  308 . The second plurality of sensors  320  can be configured to detect touch input or near touch input at the input surface  308 . For example, the plurality of sensors  320  can be an array of electrodes configured to detect a change in capacitance at the input surface  308 . Additionally, or alternatively, the second plurality of sensors  320  can include piezoelectric or strain-sensing elements configured to detect a force at the input surface  308 . After input at the input surface  308  is detected by the second plurality of sensors  320 , a signal corresponding to the user input can be generated and transmitted to another component within the base  302 , such as, the processing unit  338 . 
     The first and second plurality of sensors  318 ,  320 , the processing unit  338 , other computing components (e.g., a memory), or a combination thereof can be communicatively coupled to the substrate  324 . In some examples, the substrate  324  includes electrical traces  340  electrically coupling each of the first and second plurality of sensors  318 ,  320 , the processing unit  338 , and other computing components (e.g., a memory). The substrate  324  can include a printed circuit board (PCB) having one or more electrical components (e.g., capacitors, resistors, inductors, transistors, etc.) and logic circuitry that enable the functionality of the base  302 , as well as one or more wireless antennas as described herein. 
     The computing device  300  can use the electrical response of the sensor(s)  318 ,  320  to control a function of the computing device  300  and to provide haptic feedback (e.g., a tactile vibration) to the input surface  308 . In some examples, one or more haptic elements can provide localized haptic feedback to the input surface  308 , for example, at or near the location of the received touch and/or force input. Additionally or alternatively, haptic feedback can be provided to the input surface  308  to indicate to a user a boundary of sub-input regions (e.g., causing a tactile vibration when a user&#39;s finger traverses a perimeter of a virtual key). This can simulate a keyboard surface having discrete keys (e.g., as a keyboard having mechanically actuated key caps), but over a substantially flat dimensionally variable input surface  308 . The components involved in producing a haptic response can include an input surface and one or more actuators (such as piezoelectric transducers, electromechanical devices, and/or other vibration inducing devices). In some examples, the input surface  308  can be defined by any variety of input device including, but in no way limited to capacitive touch inputs, mechanical inputs, or optically sensed inputs. 
     The processing unit  338  can include one or more computer processors or microcontrollers that perform operations in response to receiving computer-readable instructions. The processing unit  338  can include a central processing unit (CPU) of the computing device  300  and a memory. Additionally, or alternatively, the processing unit  136  can include other processors within the computing device  300  including application specific integrated chips (ASIC) and other microcontrollers. 
     The memory can include a variety of types of non-transitory computer-readable storage media, including, for example, read access memory (RAM), read-only memory (ROM), erasable programmable memory (e.g., EPROM and EEPROM), or flash memory. The memory can store the computer-readable instructions. Additionally, or alternatively, the memory can include a variety of types of non-transitory computer-readable storage media including, for example, a hard-drive storage device, a solid state storage device, a portable magnetic storage device, or other similar device. The processing unit  338  can read computer-readable instructions stored on the memory. The computer-readable instructions can cause the processing unit  338  to perform the operations, functions, and aspects of the disclosure described herein. The computer-readable instructions can be provided as a computer-program product, software application, or the like. 
     In some examples, the computing device  300  can also include one or more power supplies or power sources (not shown) positioned within the base  302  and operably coupled to the computing components (e.g., the processing unit  338 , and/or other computing components). For example, the computing device  300  can include one or more power supplies positioned within internal volume defined by the base  302 . The one or more power supplies can be rechargeable and provide electrical power to the computing components and sensors  318 ,  320  of the computing device  300 . The one or more power supplies can include any device capable of storing and discharging electricity, such as one or more lithium-ion polymer batteries or other forms of electrical power storage. 
     In some examples, the power supply of the computing device  300  can include one or more inductive charging coils. The inductive charging coil can enable the power supply of the computing device  300  to charge using resonant inductive coupling, for example, while the computing device  300  is positioned over or adjacent a charging pad. In some examples, the inductive charging coil can provide between 5 and 15 watts of electrical power to the power supply of the computing device  300 . The inductive charging coil can be configured to operate in accordance with a known charging technology, such as, the Qi open interface standard for wireless power transfer or other mechanism for wirelessly charging an electronic device. 
     The lower portion  326  of the base  302  forms a bottom surface  342  supporting the substrate  324  and the plurality of sensors  318 ,  320 . The lower portion  326  can affix to the upper portion  316  by fasteners, clips, interlocking features, adhesives, or another mechanism for coupling the lower portion  326  to the upper portion  316 . In some examples, a barrier, gasket, or membrane (not shown) can be affixed between the lower portion  326  and the upper portion  316  to inhibit or otherwise prevent ingress of contaminants (e.g., liquid, dust particles, debris) into the internal volume of the base  302 . 
       FIGS.  7 A and  7 B  show sectional views of the computing device  300  in an opened state ( FIG.  7 A ) and the computing device  300  in a closed state ( FIG.  7 B ). In some examples, the display  304  can be retained within the channel  336  defined by the first and second walls  332 ,  334  of the retaining portion  330 . The retaining portion  330  can rotate relative to the base  302 . As such, the display  304 , which is removably coupled to the retaining portion  330 , can be rotated relative to the base  302 . As illustrated in  FIGS.  7 A and  7 B , the plurality of sensors  318 ,  320  and the substrate  324  can be disposed within the internal volume  344  defined by the base  302 . 
     The raised portion  310  of the base  302  can define a recess  346 . In some examples, the recess  346  can be formed within respective rear surface  348  of the base  302 , as shown in  FIGS.  7 A and  7 B . The retaining portion  330  can include a pivot member  350  configured to be positioned within the recess  346  and permit the retaining portion  330  to rotate relative to the base  302 . In other words, the pivot member  350  can couple or interlock with the recess  346  such that the pivot member  350  can rotate within the recess  346 . For example, the pivot member  350  can define a rotational axis about which the retaining portions  330  can rotate, pivot, or otherwise move. While the example depicted in  FIGS.  7 A and  7 B  illustrate the base  302  having a recess  346  within the rear surface  348 , the base  302  can, in other examples, include recesses in the top wall  312  of the raised portion  310  or other surfaces of the base  302 . 
     The raised portion  310  can form or define a cavity  352  configured to receive at least a portion of the second wall  334  of the retaining portion  330  when the computing device  300  is in a closed state. For example, the cavity  352  can have dimensions substantially similar to the dimensions of the second wall  334  to enable the second wall  334  to move within the cavity  352  when the retaining portion  330  is rotated into a closed state (as shown in  FIG.  7 B ). 
     Various examples of computing devices having one or more electronic devices attached thereto are described below with reference to  FIGS.  8 A- 9   .  FIGS.  8 A- 8 C  show multiple views of an example of a coupling mechanism  400  including a first retaining portion  402  and a second retaining portion  404 , each of the first and second retaining portions  402 ,  404  can be independently rotatable or pivotable relative to an intermediate portion  418 . In some examples, the coupling mechanism  400  can be substantially similar to, and include some or all of the features of coupling mechanisms described herein, such as coupling mechanism  202  depicted in  FIGS.  3 A- 4 C . For example, one or more displays and/or keyboards (not shown) can be operably coupled to the first and second retaining portions  402 ,  404  of the coupling mechanism  400  to form a computing device. Likewise, each of the first and second retaining portions  402 ,  404  can be substantially similar to the first and second retaining portions  210 ,  212  depicted in  FIGS.  3 A- 4 C .  FIG.  8 D  shows a sectional view of the coupling mechanism  400  taken through the lines  8 D of shown in  FIG.  8 C . 
     The first retaining portion  402  can include first and second walls  406 ,  408  that form a channel  410  extending between the first and second walls  406 ,  408 . The channel  410  can receive a portion of a device, such as, a display (e.g., first or second display  204 ,  206 ), a keyboard, or another device. As previously described herein, each of the first and second walls  406 ,  408  can have a respective height (see  FIGS.  7 A and  7 B ) which can be different or equivalent. In some examples the first wall  406  can be substantially parallel to the second wall  408  such that the cross sectional shape of the channel  410  is rectangular or square. In some examples, one or both of the first and second walls  406 ,  408  can be magnetic to retain a device (e.g., display  204 ) within the channel  410 . In some examples, the first retaining portion  402  can include one or more magnets which removably retain the device within the channel  410 . 
     Like the first retaining portions  402 , the second retaining portion  404  can also include first and second walls  412 ,  414  that form a channel  416  extending between the first and second walls  412 ,  414 . The channel  416  can receive a portion of a device, such as, a display (e.g., first or second display  204 ,  206 ) keyboard, or other device. As previously described herein, each of the first and second walls  412 ,  414  can have a respective height (see  FIG.  6   ) which can be different or equivalent. In some examples the first wall  412  can be substantially parallel to the second wall  414  such that the cross sectional shape of the channel  416  is rectangular or square. In some examples, one or both of the first and second walls  412 ,  414  can be magnetic to retain a device (e.g., display  204 ) within the channel  416 . In some examples, the second retaining portion  404  can include one or more magnets which removably retain the device within the channel  416 . 
     The intermediate portion  418  can form an elongated member defining a first recess  420  and a second recess  422 . In some examples, the first and second recesses  420 ,  422  can be formed within respective side surfaces  428  of the intermediate portion  418 , as shown in  FIGS.  8 A- 8 D . The first retaining portion  402  can include a first pivot member  432  configured to be positioned within the first recess  420 . The second retaining portion  404  can include a second pivot member  434  configured to be positioned within the second recess  422 . 
     The first and second pivot members  432 ,  434  can couple or interlock the first and second retaining portions  402 ,  404  to the intermediate portion  418  such that each pivot member  432 ,  434  can independently rotate relative to the intermediate portion  418 . For example, each of the first and second pivot members  432 ,  434  can define respective rotational axis about which the first and second retaining portions  420 ,  404  can rotate or pivot. While the examples depicted in  FIGS.  8 A- 8 D  illustrate the intermediate portion  418  having first and second recesses  420 ,  422  within respective side surfaces  428 , the intermediate portion  418  can include recesses in the top surface  426  or the bottom surface  430  of the intermediate portion  418  in other examples. 
     The intermediate portion  418  can form or define a cavity  436  configured to receive at least a portion of the second wall  408  of the first retaining portion  402  when the coupling mechanism  400  is in a closed state. For example, the cavity  436  can have dimensions substantially similar to the dimensions of the second wall  408  to enable the second wall  408  to move within the cavity  436  when the first retaining portion  402  is rotated into a closed state. 
     In some examples, a cross-sectional shape of the intermediate portion  418  can be rectangular or square, however, the cross-sectional shape of the intermediate portion  418  can be other geometric shapes in other examples. For example, the cross-sectional shape of the intermediate portion  418  can be triangular, ellipsoidal, spherical, or any other geometric shape. The intermediate portion  418  can include a metal, metal alloy, polymer, or any other material capable of providing the functionality disclosed herein. For example, the intermediate portion  418  can include a 6000 or 7000 series aluminum having an oxidization layer formed thereon. 
     In some examples, the intermediate portion  418  can define an internal volume housing one or more sensors, computing components (e.g., a processing unit), a battery, and similar electrical components. For example, the intermediate portion  418  can house one or more batteries or inductive charging components within the internal volume to provide electrical power to one or more devices pivotally coupled to the coupling mechanism  400 . As described herein, the coupling mechanism  400  can provide a communication pathway or conductive pathway that places devices (e.g., tablet computing devices) coupled to the coupling mechanism  400  in wireless and/or electrical communication. As such, the coupling mechanism  400  can provide a communication pathway that enables the devices to transfer power and or data between the devices. 
       FIG.  9    is an exploded view of the coupling mechanism  400  including the first and second retaining portions  402 ,  404  and intermediate portion  418 . The respective hinge mechanisms used to pivotally couple the retaining portions  402 ,  404  to the intermediate portion  418  can be any mechanism now known in the art or as may be developed in the future. For example, the hinge mechanism can be a piano hinge, a living hinge, a barrel hinge, or another similarly functioning hinge. Non-limiting examples of a hinge are described in U.S. Pat. No. 9,450,289 issued Sep. 20, 2016, the disclosure of which is hereby incorporated by reference in its entirety. 
     Various examples of computing devices having a base configured to couple to one or more electronic devices are described below with reference to  FIGS.  10 - 13   .  FIG.  10 A  shows an example of a computing device  500  including a base  502 , a first display  504 , a second display  506 , and a third display  508 . The computing device  500 , the first display  504 , the second display  506 , and the third display  508  can be substantially similar to, and can include some or all of the features of the computing devices and displays or keyboards described herein. The first display  504  can be pivotably coupled to the base  502 . Like the examples shown in  FIGS.  1 A- 2 C and  5 A- 7 B , the first display  504  can be removably coupled to a hinge  514  of the base  502 . The hinge  514  can be substantially similar to the hinges described herein and shown in  FIGS.  1 A- 2 C and  5 A- 7 C . In some examples, the base  502  can be substantially similar to the base  102  depicted in  FIGS.  1 A- 2 C and  5 A- 7 B . For example, like the base  102 , the base  502  can define an input surface  510  (beneath the second and third displays  506 ,  508 ) and a raised portion  512 . 
     As illustrated in  FIG.  10 A , the second and third displays  506 ,  508  can be positioned adjacent the input surface  510  of the base  502 . While positioned adjacent the input surface  510 , the second and third displays  506 ,  508  can provide input and output functionality to a user of the computing device  500 . For example, the second display  506  can display secondary content (e.g., a webpage or email account) to the user while the third display  508  provides a virtual keyboard configured to receive input from a user of the computing device  500 . As described herein, the second and third displays  506 ,  508  can be removably coupled to the input surface  510 , for example, using one or more magnets within the base  502  or the display  506 . In some examples, the third display  508  can be removed from the base  502  to expose a portion of the input surface  510 . The exposed portion of the input surface  510  can be configured to receive touch input or near touch input from a user of the computing device  500 . For example, the exposed portion of the input surface  510  can function as a track pad to enable a user to move a cursor on the first or second display  504 ,  506 . 
     As illustrated in  FIG.  10 B , the computing device  500  can include a keyboard  516 . The computing device  500 , the first display  504 , the keyboard  516 , and the third display  508  can be substantially similar to, and can include some or all of the features of the computing devices and displays or keyboards described herein. The keyboard  516  and the third display  508  can be positioned adjacent the input surface  510  of the base  502 . While positioned adjacent the input surface  510 , the keyboard  516  and the third display  508  can provide input and output functionality to a user of the computing device  500 . For example, the keyboard  516  can receive input from a user of the computing device  500 . As described herein, the keyboard  516  and the third display  508  can be removably coupled to the input surface  510 , for example, using one or more magnets within the base  502  or the keyboard  516 . In some examples, the third display  508  can function as a track pad to replicate the functionality of a traditional laptop (e.g., display, keyboard, and track pad). 
     In some examples, the base can be repositionable to provide multiple configurations of use, as described in  FIGS.  11 A and  11 B .  FIGS.  11 A and  11 B  show multiple example configurations of a computing device  600  including a base  602 , a first display  604 , a second display  606 , and a keyboard  608 . The computing device  600  can be substantially similar to any of the computing devices described herein, such as the computing devices  100 ,  300  shown in  FIGS.  1 A- 2 C and  5 A- 7 B .  FIG.  11 A  shows the computing device  600  in a configuration in which the base  602  is placed parallel to a support surface (e.g., a desk, table, lap of a user, or the like) and the first display is rotatably coupled to a hinge  610  of the base  602  at an oblique angle relative to the support surface. The second display  604  can be removably coupled to an input surface of the base  602  and substantially parallel to the support surface. In this configuration, the first display  604  can be the primary display while the second display  606  is the secondary display. The keyboard  608  can be communicatively coupled to at least one of the first or second displays  604 ,  606  or the base  602 , for example, the keyboard  608  can be configured to wirelessly communicate through Bluetooth or another wireless communication standard. In some examples, the first and second displays  604 ,  606 , and the keyboard  608  can be configured to receive input from a user to operate the computing device  600 . 
       FIG.  11 B  shows another configuration of the computing device  600  in which the base  602 , the first display  604 , and the second display  606  are positioned perpendicular to the support surface. The first display  604  can be rotated about the base  602  such that the base  602  and first display  604  are self-supported in a standing position. In some examples, the first display  604  and the second display  606  can operate as a single display screen. In other words, content shown at the first display  604  can extend onto the second display  606  or can be dragged onto the second display  606  by a user of the computing device  600 . This configuration can be beneficial, for example, when a user desires a computing device having a larger display screen. Alternatively or additionally, the first display  604  can depict a first content to the user while the second display  606  depicts a second content to the user. In some examples, the first and second displays  604 ,  606 , and the keyboard  608  can be configured to receive input from a user to operate the computing device  600 . 
     In some examples, the computing device can include a base configured to simultaneously support and interface with multiple input devices, as described below with reference to  FIGS.  12 A and  12 B .  FIG.  12 A  shows an example computing device  700  including a base  702 , a display  704 , a keyboard  706  positioned on the base, and an input device  708  positioned on the base. The keyboard  706  can be substantially similar to keyboard  108  of  FIGS.  1 A- 2 C , and can include some or all of the features of the keyboard  108 . The input device  708  can simultaneously occupy an input surface (e.g., input surface  308 ) of the base  702  with the keyboard  706 . For example, the input device  708  can define an engagement surface  710  which contacts at least a portion of the input surface (e.g., input surface  308 ) of the base  702 . The engagement surface  708  can be recessed such that a side wall  712  of the base  702  interfaces with a wall  714  of the input device  708  having a substantially similar size and shape as the side wall  712 . The size and shape of the side wall  712  and the engagement surface  708  can cause a raised portion  720  of the base  702  to be flush with the keyboard  706  and the input device  708 . The input device  708  can also form a base portion  716  that supports the input device  708  and extends flush with a bottom surface of the base  702 . As such, the input device  708  can be positioned adjacent the keyboard  706  and can provide an extended or enlarged input area for the computing device  700 . 
     One or more of power and/or data can be transferred through the engagement between the engagement surface  710  and the input surface of the base  702 . In some examples, power and/or data can be transferred through a direct electrical connection. In some examples, power and/or data can be wireless transferred, for example, through inductive coupling or one or more wireless antennas or components. For example, the input device  708  can house one or more batteries which supply electrical power to the computing device  700 . Additionally, or alternatively, the input device  708  can house one or more processors which supply processing capabilities to the computing device  700 . In some examples, the input device  708  can function as a trackpad or sketching surface for a stylus  718  or other similar sketching tools. 
       FIG.  12 B  shows the computing device  700  of  FIG.  12 A  in a closed state arranged in a configuration wherein the input device  708  is positioned on the display  704 . As illustrated in  FIG.  12 B , the keyboard  706  can be positioned between the base  702  and the display  704  while the computing device  700  is in a closed state. While the computing device  700  is in a closed state and the keyboard  706  is positioned between the base  702  and the display  704 , the display  704  and/or the input device  708  can be deactivated or non-functioning to prevent unintentional or accidental input to the computing device  700 . By positioning the keyboard  706  between the base  702  and the display  704 , the keyboard  706  can be protected or shielded from potential damage when transporting the computing device  700 . Moreover, the display  704  can be protected or shielded from damage by the input device  708 . 
     If the computing device  700  is opened by a user to an open state, the display  704  and/or the keyboard  706  can be activated or rendered operable. The input device  708  can be removably affixed to the display  704 , for example, by one or more magnets positioned within the display  704  and/or the input device  708 . In some examples, the display  704  can include metal that interacts with one or more magnets within the input device  708  to removably couple the input device  708  to the display  704 . 
     In some examples, the component positioned on the first display  704  (e.g., the second display  708  in  FIG.  12 A  or the keyboard  706  in  FIG.  2 C ) can remain affixed to the first display  704  while the computing device  700  is opened by a user, and can remain affixed while the computing device  700  is left in an open state. Although reference has been made to the first and second displays  704 ,  708  in particular positions within the computing device  800 , the first display  704  can be substituted for the second display  708 , and vice versa. For example, the relative positions and functions of the first and second displays of  FIG.  12 A  can be swapped such that the first display  704  is positioned outside of the closed computing device  700 . 
     In some examples, the computing device can include a base configured to interface with other input devices, as described below with reference to  FIGS.  13  and  14   .  FIG.  13    shows an example computing device  800  including a base  802 , a display  804 , and an input device  806  positioned on the base  802 . The computing device  800  can be substantially similar to and include some or all of the features of any of the computing devices described herein. The input device  806  can be configured to provide input to the computing device  800 , for example, the input device  806  can be communicatively coupled to at least one of the base  802  or the display  804 . Thus, the input device  806  can include a variety of input mechanisms which are detectable by the base  802  and/or the first display  804 , for example, via an electrical or wireless communication with the base  802  and/or first display  804 , or through sensors in the base  802 , for example, as described with respect to the base  302 . In some examples, the input device  806  can include at least one of a knob  808 , a button  810 , a toggle  812 , a slider  814 , a turntable  816 , or other input mechanisms (e.g., dials, switches, levers, and piano keys) configured to provide input to the base  802  or display  804  to control operational aspects of the computing device  800 . The computing device  800  can be utilized by a music producer, a disc jockey, an audio engineer, or the like to generate music in one configuration while also being modular to permit the user to remove the input device  806  and removably attach a keyboard or second display (not shown) to the base  802  to provide traditional laptop functionality. Thus, the computing device  800  be reconfigurable or modular to efficiently accommodate users in various operational applications (e.g., music productions, sketching, document preparation, online shopping, video conferencing, and so on). 
       FIG.  14    depicts an example of a computing device  900  including a base  902  and a display  904 . The base  902  can be substantially similar to the other bases described herein, such as depicted in  FIGS.  1 A- 2 C,  5 A- 7 B, and  10 - 13   . For example, like the other bases, the base  902  can define an input surface  906  and a raised portion  908 . The input surface  906  can be configured to receive input from the user of the computing device  900 , such as touch input or near touch input at the input surface  906 . Additionally, or alternatively, the computing device  900  can detect user gestures at or above the input surface  906 . As illustrated in  FIG.  14   , a user can make a gesture with their hand or another object which is detectable by the computing device  900 . For example, the raised portion  908  can include a plurality of sensors configured to detect movement above the input surface  906 . The example gesture depicted in  FIG.  14    illustrates a user turning or flipping a virtual page of a book or magazine being displayed at the display  904 . Other gestures can be recognized by the computing device  900 , for example, pinch/zoom gestures, swiping gestures, scrolling gestures, and/or rotating gestures. 
     In some examples, the base can include a hinge which is rotatably coupled to the base as described below with reference to  FIGS.  15 A and  15 B .  FIGS.  15 A and  15 B  illustrate an example of a base  1000  having a hinge  1002 . The hinge  1002  is illustrated in an opened state in  FIG.  15 A  and in a closed state in  FIG.  15 B . The hinge  1002  can include substantially similar features and functionality as the hinges depicted in  FIGS.  1 A- 2 C,  5 A- 7 B, and  10 - 13   . For example, the hinge  1002  can be configured to removably couple to an electronic device (e.g., a tablet computing device) and rotate the electronic device relative to the base  1000 . In some examples, the hinge  1002  can be rotated from an angle of 0 degrees relative to the base  1000  (i.e., a closed state as shown in  FIG.  15 B ) to a an angle between about 0 degrees and about 180 degrees relative to the base  1000  (i.e., an opened state as shown in  FIG.  15 A ). 
     Various examples of hinges of a computing device are described below with reference to  FIGS.  16 A- 16 C .  FIGS.  16 A- 16 C  show a computing device  1100 . The computing device  1100  can be substantially similar to and include some or all of the features of any of the computing devices described herein. The computing device  1100  can include a base  1102 , a display  1104 , a hinge  1106 , and another device (not shown) positioned between the base  1102  and the display  1104 . As shown, the display  1104  can be positioned such that a display screen  1108  of the display  1104  is facing away from the base  1102 . While in this configuration, a first wall  1110  of the hinge  1106  can obstruct or block a portion of the display screen  1108  (as shown in  FIG.  16 A ). Significant obstruction of the display screen  1108  can be undesirable to a user of the computing device  1100 . Thus, the hinge  1106  can include various features provide an active display area at the hinge  1106  (as shown in  FIGS.  16 B and  16 C ). In some examples, as shown in  FIG.  16 B , the hinge  1106  can include a window  1112  formed within the first wall  1110  that enables a user of the computing device  1100  to view a significant portion of the display screen  1108  that would have otherwise been obstructed by the first wall  1110 . 
     In some examples, as shown in  FIG.  16 C , the hinge  1106  can include a sub-display  1114  positioned adjacent the first wall  1110  and configured to replicate or reproduce the portion of the display screen  1108  that is obstructed by the first wall  1110 . Additionally or alternatively, the sub-display  1114  can be configured to display additional content, for example, a time of day, a current date, a current battery level of the computing device  1100 , a volume setting, open application icons, other content, or combinations thereof. 
     The sub-display  1114  can be any form of display, component, or device used to display visual content to a user. For example, in some examples the sub-display  1114  can be an LED display, an OLED display, or an LCD display. In some examples, the sub-display  1114  can be any form of display now known in the art or as may be developed in the future. In some examples, the sub-display  1114  can be a touch screen display, or can have touch detecting capabilities, such as, capacitive touch, force touch, and near touch capabilities. 
     Any of the features or aspects of the computing devices discussed herein can be combined or included in any combination. For example, a computing device can include a base and one or more displays and/or keyboard attached thereto. The one or more displays and/or keyboard can be rotatable relative to the base and removably attached to one or more retaining portions. Further, the components of the computing devices described herein, including components that can be fully or partially removable, can be housed entirely within an internal volume. For example, an internal volume defined by the base. 
     Any of the features or aspects of the computing devices discussed herein can be combined or included in any combination. For example, a computing device can include a coupling mechanism and one or more displays and/or keyboard attached thereto. The one or more displays and/or keyboard can be rotatable relative to the coupling mechanism and removably attached to one or more retaining portions. Further, the components of the computing devices described herein, including components that can be fully or partially removable, can be housed entirely within an internal volume. For example, an internal volume defined by the intermediate portion of the coupling mechanism. 
     To the extent applicable to the present technology, gathering and use of data available from various sources can be used to improve the delivery to users of invitational content or any other content that may be of interest to them. The present disclosure contemplates that in some instances, this gathered data can include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, TWITTER® ID&#39;s, home addresses, data or records relating to a user&#39;s health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information. 
     The present disclosure recognizes that the use of such personal information data, in the present technology, can be used to the benefit of users. For example, the personal information data can be used to deliver targeted content that is of greater interest to the user. Accordingly, use of such personal information data enables users to calculated control of the delivered content. Further, other uses for personal information data that benefit the user are also contemplated by the present disclosure. For instance, health and fitness data can be used to provide insights into a user&#39;s general wellness, or can be used as positive feedback to individuals using technology to pursue wellness goals. 
     The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of or access to certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country. 
     Despite the foregoing, the present disclosure also contemplates examples in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, in the case of advertisement delivery services, the present technology can be configured to allow users to select to “opt in” or “opt out” of participation in the collection of personal information data during registration for services or anytime thereafter. In another example, users can select not to provide mood-associated data for targeted content delivery services. In yet another example, users can select to limit the length of time mood-associated data is maintained or entirely prohibit the development of a baseline mood profile. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app. 
     Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user&#39;s privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods. 
     Therefore, although the present disclosure broadly covers use of personal information data to implement one or more various disclosed examples, the present disclosure also contemplates that the various examples can also be implemented without the need for accessing such personal information data. That is, the various examples of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data. For example, content can be selected and delivered to users by inferring preferences based on non-personal information data or a bare minimum amount of personal information, such as the content being requested by the device associated with a user, other non-personal information available to the content delivery services, or publicly available information. 
     The foregoing description, for purposes of explanation, used specific nomenclature to provide a thorough understanding of the described examples. However, it will be apparent to one skilled in the art that the specific details are not required in order to practice the described examples. Thus, the foregoing descriptions of the specific examples described herein are presented for purposes of illustration and description. They are not target to be exhaustive or to limit the examples to the precise forms disclosed. It will be apparent to one of ordinary skill in the art that many modifications and variations are possible in view of the above teachings.
