Title: Input devices having a deformable membrane and methods of using the same

Description:
TECHNICAL FIELD 
     Embodiments described herein generally relate to input devices and, more particularly, to input devices having a deformable membrane for controlling computing devices and robots. 
     BACKGROUND 
     Input devices are used to control or otherwise provide input to an electronic device. One example input device is a mouse that is used to provide inputs to a computing device, such as a personal computer. The mouse is used to control a mouse cursor displayed on the electronic display of the computing device. However, the mouse is limited to the number of input buttons it has, and the mouse does not enable an input based on the amount of force applied to the buttons. 
     Additionally, an electronic device configured as a robot typically needs to be controlled or otherwise trained, which may be an arduous task. Robot training devices also do not have force-sensitive input controls, and are not natural for users to control the robot. 
     Thus, alternative input devices for electronic devices may be desired. 
     SUMMARY 
     In one embodiment, an input device includes a body, a deformable membrane coupled to the body such that the body and the deformable membrane define an enclosure filled with a medium, and an internal sensor disposed within the enclosure, the internal sensor having a field of view configured to be directed through the medium and toward a bottom surface of the deformable membrane. The input device further includes a controller configured to receive an output signal from the internal sensor corresponding to a deformation in the deformable membrane, determine a gesture based on the output signal from the internal, and provide a gesture signal corresponding to the gesture. 
     In another embodiment, a method of controlling an electronic device using an input device includes receiving, from an internal sensor within an enclosure filled with a medium defined by a body and a deformable membrane, an output signal corresponding to a deformation of the deformable membrane, determining a gesture from the output signal of the internal sensor, and providing a gesture signal corresponding to the gesture to a computing device. 
     These and additional features provided by the embodiments described herein will be more fully understood in view of the following detailed description, in conjunction with the drawings.

     DETAILED DESCRIPTION 
     Embodiments of the present disclosure are directed to input devices having a deformable membrane and methods of operating an input device having a deformable membrane. Typical input devices, such as computer mice, are limited into the number of buttons to be used as inputs to an electronic device, such as a personal computer. Further the locations of the buttons are static in nature, and cannot be moved by the user. Traditional computer mice also do not provide for the ability to use force as an input control to the electronic device. In an example, the amount of force a user applies to the input device could control the input to the electronic device (e.g., greater force provides a greater value of whatever parameter the input device is being used to input). However, traditional input devices do not have this capability. 
     Additionally, traditional robot training devices are difficult to operate, and commonly can only be done by trained professionals. These devices may have many static inputs that a user must learn to properly control the robot. Thus, traditional robot training devices are unsatisfactory. 
     Embodiments of the present disclosure employ an input device having a body and a deformable membrane that is attached to the body. The deformable membrane and the body define an enclosure that is filled with a medium. An internal sensor detects a location of one or more indentions in the deformable membrane caused by a user, such as by the user&#39;s fingers or an object pressed into the deformable membrane. Indentions in different locations may be used as different inputs. Thus, the input device can be programmed to have “buttons” at any location on its surface. Further, various gestures can be used as inputs, such as sliding a finger in a motion on the deformable membrane. The input device may also be used to train or otherwise control a robot. Many other applications for the input devices described herein are possible. 
     Various embodiments of input devices configured as deformable sensors are described hereinbelow. 
     Referring now to  FIGS. 1 and 2 , an example deformable sensor  100  that may be used as an input device to a computing device (e.g., a desktop computer, a laptop computer, a tablet, a smartphone and the like) or a robot is schematically illustrated.  FIG. 1  is a front elevation view of the example deformable sensor  100  and  FIG. 2  is a top perspective view of the example deformable sensor  100 . The example deformable sensor  100  generally comprises a housing  110  and a deformable membrane  120  coupled to the housing  110 , such as by an upper portion  111  of the housing  110 . The housing  110  and the deformable membrane  120  define an enclosure  113  that is filled with a medium through one or more passthroughs  112 , which may be a valve or any other suitable mechanism. The passthrough  112  may be utilized to fill or empty the enclosure. In one example, the medium is gas, such as air. Thus, air may be pumped into the enclosure  113  to a desired pressure such that the deformable membrane  120  forms a dome shape as shown in  FIG. 1 , although any suitable shape may be utilized in other embodiments. In another example, the medium is a gel, such as silicone or other similar substance. In some embodiments, a substance such as solid silicone may be cast in a given shape before assembly of the deformable sensor  100 . In various embodiments, the medium may be anything that is transparent to an internal sensor (discussed in more detail below), such as to a wavelength of a time of flight sensor. The medium may include clear/transparent rubbers in some embodiments. In other embodiments the medium may be a liquid. In some examples, the deformable membrane  120  and the medium within the enclosure  113  may be fabricated of the same material, such as, without limitation, silicone. In some embodiments the deformable sensor  100  may be mountable. For example, the enclosure  113  may include brackets to be mounted any suitable object (such as a robot) or material. The deformable membrane  120  may be a latex or any other suitable material, such as a suitably thin, non-porous, rubber-like material. 
     The deformability of the deformable sensor  100  may be tuned/modified by changing the material of the deformable membrane  120  and/or the pressure within the enclosure  113 . By using a softer material (e.g., soft silicone), the deformable sensor  100  may be more easily deformed. Similarly, lowering the pressure within the enclosure  113  may also cause the deformable membrane  120  to more easily deform, which may in turn provide for a more deformable sensor  100 . 
     An internal sensor  130  capable of sensing depth may be disposed within the enclosure  113 , which may be measured by the depth resolution of the internal sensor  130 . The internal sensor  130  may have a field of view  132  directed through the medium and toward a bottom surface of the deformable membrane  120 . As described in more detail below, the internal sensor  130  may be capable of detecting deflections of the deformable membrane  120  when the deformable membrane  120  comes into contact with an object. 
     An internal sensor  130  capable of sensing depth may be disposed within the enclosure  113 , which may be measured by the depth resolution of the internal sensor  130 . The internal sensor  130  may have a field of view  132  directed through the medium and toward a bottom surface of the deformable membrane  120 . In some embodiments the internal sensor  130  may be an optical sensor. As described in more detail below, the internal sensor  130  may be capable of detecting deflections of the deformable membrane  120  when the deformable membrane  120  comes into contact with an object. In one example, the internal sensor  130  is a time-of-flight sensor capable of measuring depth. The time-of-flight sensor emits an optical signal (e.g., an infrared signal) and has individual detectors (i.e., “pixels”) that detect how long it takes for the reflected signal to return to the sensor. The time-of-flight sensor may have any desired spatial resolution. The greater the number of pixels, the greater the spatial resolution. The spatial resolution of the sensor disposed within the internal sensor  130  may be changed. In some cases, low spatial resolution (e.g., one “pixel” that detects a single point&#39;s displacement) may be desired. In others, a sensitive time-of-flight sensor such may be used as a high spatial resolution internal sensor  130  that provides dense tactile sensing. Thus, the internal sensor  130  may be modular because the sensors may be changed depending on the application. In some embodiments robots feature varying touch sensitivity due to varying spatial resolution and/or depth resolution. 
     However, utilizing a time-of-flight sensor may not be ideal for a variety of reasons. A time-of-flight sensor may larger than other types of sensors. As such, in order to accommodate a time-of-flight sensor, the deformable sensor  100  may need to be larger than may otherwise be desired, thereby constraining the size of the deformable sensor  100 . In addition, a time-of-flight sensor may have undesirable range limitations. In particular, at very close ranges, a time-of-flight sensor may not properly determine depths. Accordingly, in some embodiments, the internal sensor  130  may comprise an imaging sensor configured to capture an image of the deformable membrane  120  and determine depth of the various points of the deformable membrane  120  based on the captured image. Estimating depth from a single image is inherently an ill-posed problem since there are infinite possible world states that could have generated the image. However, it is possible to train a neural network to learn appearance-based features capable of outputting a dense depth map containing per-pixel distance estimates. Accordingly, the internal sensor  130  may utilize a trained neural network to estimate depth based on a captured image, as disclosed herein. 
     In one example, the internal sensor  130  may comprise a monocular image sensor configured to capture an image of the deformable membrane  120 . However, in other examples, the internal sensor  130  may comprise any other type of camera or imaging sensor capable of capturing images. In embodiments, the internal sensor  130  may capture an image of the deformable membrane  120  when it is deformed by an object and may determine a depth value for each pixel of the captured image utilizing a trained neural network, as described below. 
     A neural network may be trained to receive an image captured by the internal sensor  130  and estimate a depth value for each pixel of the image during a training phase. After the neural network is trained, the neural network may be used to estimate a depth value for each pixel of a captured image during an operation phase. In order to train such a neural network, a large number of training examples may be acquired during the training phase, and the neural network may be trained using supervised learning techniques, as disclosed herein. In particular, training examples may comprise captured example images along with ground truth values comprising known depth values for the pixels of each captured image. Additional information regarding an internal sensor with monocular depth estimation is provided in U.S. patent application Ser. No. 17/147,935 entitled “Robust and Perceptive Manipulation Through Soft-Bubble Grippers and Monocular Depth,” which is hereby incorporated by reference in its entirety. 
     The deformable sensors described herein may be used as an input device to control or otherwise provide input to an electronic device, such as, without limitation, a computing device or a robot.  FIG. 3  illustrates an example computing environment  201  comprising an input device  200  configured as a mouse-like input device for providing input to a computing device  240 . In the illustrated embodiment, the computing device  240  is an all-in-one personal computer. However, it should be understood that the computing device may be a laptop, a tablet, a server, or any other type of computing device. The example computing environment  201  further includes a keyboard  242  for providing additional inputs to the computing device  240 . 
       FIGS. 4A-3C  illustrate the example input device  200  shown in  FIG. 3  in greater detail.  FIG. 4A  is a side elevation view of the input device  200 ,  FIG. 4B  is a top perspective view of the input device  200 , and  FIG. 4C  is a top view of the input device  200 . The example input device  200  is generally shaped and configured as computer mouse device. However, embodiments are not limited by the shape and configuration of the input device. in the illustrated example, the input device includes a rigid body  210 , and a deformable membrane  220  which is attached to the rigid body  210  to define an enclosure (not shown) in a manner similar to the housing  110  and deformable membrane  120  illustrated in  FIGS. 1 and 2 . The input device  200  further includes an internal sensor (not shown, but similar to the internal sensor  130  shown in  FIG. 2 ) within the enclosure that is configured to detect deformation of the deformable membrane  120 . 
     The example input device  200  further includes an optical sensor  215  within a bottom surface of the body  210  that is configured to track a position of the input device  200  on a surface, such as to control a mouse cursor on an electronic display of the computing device  240 , for example. The optical sensor  215  may be configured as a mouse laser diode and photodiode for producing a position signal, for example. Thus, a user may use the input device  200  to move a mouse cursor on an electronic display in a traditional manner in some embodiments. It should be understood that in other embodiments no optical sensor is provided. 
     The input devices described herein enable inputs that were not previous possible using conventional input device, such as mice. The deformable membrane  220  enables any region of the top surface of the input device  200  to be configured as a selectable region and thus a “button.” For example, a top-left region  222 A may be configured to function as a left-button of a traditional mouse input device. Thus, when the user deforms the deformable membrane  220  with his or her index finger of the right hand, the internal sensor detects this deformation and produces an output similar to that of a left-button click of a traditional mouse input device. Similarly, a top-right region  222 B may be configured to function as a right-button of a traditional mouse input device. 
     Referring now to  FIG. 4D , in some embodiments, a pattern  226  may be provided on an underside  224  of the deformable membrane  220  to assist the detection of the deformation of the deformable membrane  220 . The pattern  226  may make it easier for a depth sensor or a monocular image sensor to detect the deformation of the deformable membrane  220 . In the illustrated example, the pattern  226  is an array of dots printed or otherwise applied to the underside  224  of the deformable membrane  220 . The internal sensor may detect the movement of the dots, for example. However, embodiments are not limited to an array of dots. The pattern may be an arbitrary pattern of arbitrary shapes. As another example, the pattern may be lines defining a grid. It should be understood that other embodiments do not include a pattern. 
     Because the deformable membrane  220  may be deformed at any location and in many different manners, many other gestures may be used as input to the computing device  240  using the input device  200 . Embodiments are not limited to any type of gesture. In some embodiments, the user may program the input device  200  to recognize particular gestures and what actions the computing device makes in response to those gestures. Thus, the input device  200  may be fully configurable and customizable. As a non-limiting example, a user may program different gestures for different software applications executed on the computing device  240 . 
       FIG. 5A  illustrates one example gesture applied to the input device  200 . In this example, the user squeezes the deformable membrane using a thumb and one of a middle finger, a ring finger, and a pinky finger to create a first indentation  230 A and a second indentation  230 B in the deformable membrane  220 . The internal sensor detects the first indentation  230 A and the second indentation  230 B and produces a gesture signal, which is received by the computing device  240 . The gesture signal may be provided to the computing device  240  by a wired or wireless connection. As a non-limiting example, the input device  200  is configured to send the gesture signal (as well as the tracking signal provided by the optical sensor  215 ) by the Bluetooth® wireless communication standard. 
     The gesture shown in  FIG. 5A  may cause a software program running on the computing device  240  to react in any number of ways. For example, squeezing the deformable membrane  220  may cause a graphical representation of an object to be picked up and moved. Releasing the deformable membrane  220  may cause the graphical representation of the object to be dropped in a digital design space. This is just one of countless examples. 
       FIG. 5B  illustrates another gesture wherein a first indentation  231 A and a second indentation  231 B are made in the deformable membrane  220  simultaneously. Three, four, or even five indentations may be made simultaneously to provide additional gestures. Further, the whole palm of a user&#39;s hand may be pressed into the deformable membrane to generate a gesture. Many other gestures are also possible. 
     Gestures are not limited to static gestures. A user may move one or more indentations on the deformable membrane.  FIG. 5C  illustrates an example wherein an indentation  232  is made near the top of the deformable membrane  220 , and then moved down toward the bottom as indicated by arrow A. One or more indentations may be moved in any direction, such as in a circular direction, a lateral direction, a vertical direction, and the like. A user may move two indentations closer together, or move two indentations further apart, for example. These movements produce different gestures for receipt and interpretation by the computing device  240 . As a non-limiting example, a user may move an indentation on the deformable membrane  220  to move a mouse cursor on the electronic display. 
     The deformable membrane  220  also provides the ability for the input device  200  to produce gesture signals based on a depth of indentations made into the deformable membrane  220 . Thus, the depth into which a user presses into the deformable membrane may control functions of a software program executed by computing device  240 . As a non-limiting example, the further the user depresses into the deformable membrane  220 , the more a particular setting increases (e.g., volume of sound emitted from the computing device  240 ). Thus, the input devices of the present disclosure add an additional dimension for providing gestural inputs to a computing device over traditional input devices. 
     It is noted that the input devices described herein act as passive haptic devices. The further a user presses into the deformable membrane, the more difficult it is to further deform the deformable membrane and press in deeper. Thus, the input device provides an elastic feedback to the user so that the user knows how deeply he or she has pressed into the input device. 
     In some embodiments, the input device  200  includes a pump device  510  (see  FIG. 8 ) that is operable to change the pressure within the enclosure. The pressure may be changed according to user preferences and comfort, for example. The pressure may also be changed to change the sensitivity of the input device  200  with respect to gestures using the depth of the indentations into the deformable membrane  220 . When the pressure is increased, it is more difficult to deform the deformable membrane  220 , and thus the sensitivity of the input device  200  is increased. When the pressure is decreased, it is easier to deform the deformable membrane  220 , and thus the sensitivity of the input device  200  is decreased. 
     Embodiments are not limited to input devices configured as a mouse input device. Rather, the input devices described herein may take on any shape and configuration. Referring now to  FIG. 6 , an example input device  300  configured as a tablet rather than a mouse input device is illustrated. The tablet shape may provide a larger working surface for the user to perform more complex tasks, such as train or otherwise control a robot, for example. The example input device  300  includes a body  310  and a deformable membrane  320  attached to the body  310 . The deformable membrane  320  and the body  310  define an enclosure filled with a medium. One or more internal sensors are disposed within the enclosure and have a field of view of an underside of the deformable membrane  320 . Depending on the size of the input device  300 , it may desirable to have multiple internal sensors within the enclosure. 
     The deformable membrane  320  defines a working space. In the illustrated embodiment, the deformable membrane is divided into a plurality of zones  360 . Each zone may be used to provide a different input and/or functionality to the electronic device that is being controlled. However, embodiments are not limited to the working space being divided into zones. Similar to the input device  200  shown in  FIGS. 4A-4C , any number of gestures may be impressed into the deformable membrane  320  to generate gesture signals. 
     The larger working space provided by the table-style input device  300  may enable users to impress an object into the deformable membrane  320 . In some embodiments, the input device  300 , alone or in conjunction with a computing device, may detect both the type of the object and the pose of the object based on the deformation of the deformable membrane  320 . As a non-limiting example, the input device  300  may be used to train a robot to detect a type of object and a pose of the object using a deformable sensor as a robot end effector.  FIG. 7  provides an example of a first robot  401 A and a second robot  401 B cooperating to manipulate an object  415 . It should be understood that embodiments are not limited to two robots, and that a single robot may also be utilized. In the illustrated example, the first robot  401 A has a first deformable sensor  470 A, and the second robot  401 B has a second deformable sensor  470 B. The first and second deformable sensors  470 A,  470 B make contact with the object  415 , which leaves an imprint on both the first and second deformable sensors  470 A,  470 B. Based on the imprints, the first and second robots  401 A,  401 B may detect the type and the pose of the object  415 . 
     The tablet input device  300  may be used to train the robots to detect the type and pose of objects. For example, the user may imprint an object into the working space of the input device  300  at a plurality of poses, and input into a computing device the type of object and the pose of the object for each imprint. In this manner, a user may teach the robot various objects and their poses so that the robot may automatically detect a type and pose of an object in a tactile fashion using a deformable sensor. Embodiments of the present disclosure may utilized object type and pose detection using the processes described in U.S. Pat. No. 10,668,627, which is hereby incorporated by reference in its entirety. 
     The input device  300  of  FIG. 6  may be used to train or otherwise control a robot in other ways. For example, first gesture in the deformable membrane  320  may be used to control the end effector of a robot, and a second gesture in the deformable membrane  320  may be used to control the joints of a robot. As a non-limiting example, moving two fingers across the working space of the deformable membrane  320  may produce a first control signal may cause the end effector to move in a certain way, and moving three fingers across the working space of the deformable membrane  320  may produce a second control signal that may cause one or more joints to move in a certain way (i.e., a robot joint control signal). 
     Other applications for the input devices described herein are also possible. An input device, such as the input device  300  shown in  FIG. 6 , may be used as an input device and/or a musical instrument in the production and/or performance of music. For example, the input device  300  may include electronic components such that it is configured as an interface for a real-time effects processor and/or sampler for use in the creation of music. For example, the various zones  360  of the deformable membrane  320  may be used as individual inputs to produce different effects. In some embodiments, the input device includes light sources (e.g., light emitting diodes) within the enclosure that are configured to illuminate the specific zones  360  to show the user which zones are active and producing sound. The depth the user presses into the deformable membrane  320  (e.g., within a zone  360 ) may also control the sound that is emitted. Thus, a pressure control is also provided, which greatly expands the functionality of the input device  300  for producing music. The deformable nature of the input device  300  provides the user with passive haptic feedback because the user can feel the change in resistance as his or her finger(s) are pressed into the deformable membrane  320 . 
     Turning now to  FIG. 3 , a block diagram illustrates an example of a computing environment  500  through which embodiments of the disclosure can be implemented, such as (by way of non-limiting example) a deformable sensor  100 , an internal sensor  130 , or any other device described herein. The computing environment  500  described herein is but one example of a suitable computing device and does not suggest any limitation on the scope of any embodiments presented. Nothing illustrated or described with respect to the computing environment  500  should be interpreted as being required or as creating any type of dependency with respect to any element or plurality of elements. In various embodiments, a computing environment  500  may include but need not be limited to, an input device  100  and/or an internal sensor  130 . In some embodiments, the input device  100  itself includes some or all of the components shown in  FIG. 8 . In other embodiments, components shown in  FIG. 8  are provided across two or more hardware devices (e.g., a deformable sensor  100  and a computing device) 
     In an embodiment, the computing environment  500  includes at least one processor  502  and at least one memory component  506  (e.g., non-volatile memory and/or volatile memory). In some embodiments, the at least one processor  502  and the at least one memory component  506  are solely within the input device  100 . In other embodiments, the at least one processor  502  and the at least one memory component  506  are disposed within one or more of the input device  100  and a remote computing device. The computing environment  500  can include one or more displays and/or output devices  508  such as monitors, speakers, headphones, projectors, wearable-displays, holographic displays, and/or printers, for example. The computing environment  500  may further include one or more other input devices  507  which can include, by way of example, any type of mouse, keyboard, disk/media drive, memory stick/thumb-drive, memory card, pen, touch-input device, biometric scanner, voice/auditory input device, motion-detector, camera, scale, etc. 
     The computing environment  500  may include computer readable storage medium  506  in the form of memory (e.g., non-volatile such as ROM, flash memory, etc., and or volatile memory such as RAM). The computer readable storage medium  506  may comprise a plurality of computer readable mediums, each of which may be either a computer readable storage medium or a computer readable signal medium. A computer readable storage medium can include tangible media that is able to store instructions associated with, or used by, a device or system. A computer readable storage medium includes, by way of non-limiting examples: RAM, ROM, cache, fiber optics, EPROM/Flash memory, CD/DVD/BD-ROM, hard disk drives, solid-state storage, optical or magnetic storage devices, diskettes, electrical connections having a wire, or any combination thereof. A computer readable storage medium may also include, for example, a system or device that is of a magnetic, optical, semiconductor, or electronic type. Computer readable storage media and computer readable signal media are mutually exclusive. 
     A computer readable signal medium can include any type of computer readable medium that is not a computer readable storage medium and may include, for example, propagated signals taking any number of forms such as optical, electromagnetic, or a combination thereof. A computer readable signal medium may include propagated data signals containing computer readable code, for example, within a carrier wave. Computer readable storage media and computer readable signal media are mutually exclusive.
