     DETAILED DESCRIPTION 
     The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configurations in which the subject technology may be practiced. The appended drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will be clear and apparent to those skilled in the art that the subject technology is not limited to the specific details set forth herein and may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring the concepts of the subject technology. 
     Some electronic devices that include a display surface and/or a touch panel receive tactile input from a user. For example, a stylus can be utilized to provide input by contacting a touch panel of an electronic device. The touch panel may include a touch sensitive surface that, in response to detecting a touch event, generates a signal that can be processed and utilized by other components of the electronic device. A display component of the electronic device may display textual and/or graphical display elements representing selectable virtual buttons or icons, and the touch sensitive surface may allow a user to navigate the content displayed on the display screen. Typically, a user can move one or more input devices, such as a stylus, across the touch panel in a pattern that the device translates into an input command. 
     A housing of a stylus can define an outer surface thereof and include plastics or other materials that provide adequate rigidity while allowing wireless signals to be transmitted through the housing. A coating layer can be provided to harden the exterior surface of the housing. However, such coating layers can be uneven. Additionally, plastics and coating layers are generally porous and susceptible to infiltration by debris, especially when the stylus is frequently handled and contacting other surfaces. 
     In accordance with embodiments disclosed herein, a stylus can be provided with a glass member that defines a portion of an outer periphery of the stylus. The glass member can facilitate magnetic coupling with a host device and wireless charging from the host device. The glass member can also facilitate detection of touch input with a capacitive touch sensor within the stylus. The glass member also provides a durable outer surface along a section of the stylus to resist infiltration of debris and reduce the effects of wear. The glass member can be provided in a variety of shapes and arrangements that offer aesthetic options and customization for personal preferences. 
     These and other embodiments are discussed below with reference to  FIGS. 1-20 . 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. 
     A touch-based input device in accordance with embodiments disclosed herein can include any device that is held, worn, or contacted by a user for providing input and/or receiving feedback. The touch-based input device can be used alone or in conjunction with another device. For example,  FIG. 1  illustrates a system  1  including a stylus  100  and a host device  90  having a surface  50 , according to some embodiments of the subject technology. The stylus  100  can be held by a user  10  and operate as a touch-based input device for use with the host device  90 . 
     The surface  50  of the host device  90  can include a display surface and/or a touch panel for interacting with the stylus  100  when contacted thereby. The host device  90  utilizes the display to render images to convey information to the user. The display can be configured to show text, colors, line drawings, photographs, animations, video, and the like. The surface  50  of the host device  90  can be implemented with any suitable technology, including, but not limited to, a multi-touch and/or multi-force sensing touchscreen that uses liquid crystal display technology, light-emitting diode technology, organic light-emitting display technology, organic electroluminescence technology, electronic ink, or another type of display technology or combination of display technology types. 
     The stylus  100  can include a tip  190  for contacting the surface  50 . Such contact can be detected by the host device  90  and/or the stylus  100 . For example, the stylus  100  can include one or more sensors that detect when the tip  190  contacts and applied pressure to the surface  50 . Such sensors can include one or more contact sensors, capacitive sensors, touch sensors, cameras, piezoelectric sensors, pressure sensors, proximity sensors, electric field sensors, photodiodes, and/or other sensors operable to detect contact with the surface  50 . Such sensors can optionally operate cooperatively with the host device  90  to detect contact with the surface  50 . 
     As shown in  FIG. 2 , the stylus  100  can include components that support handling and operation by a user. Inputs can be provided by a user at one or more components of the stylus  100 . 
     A force sensor  192  can be operated to detect user inputs at the tip  190  of the stylus  100 . The force sensor  192  can interact with both the tip  190  and the housing  110  to detect relative motion of the tip  190  and the housing  110 . For example, the force sensor  192  can be operated to detect when the tip  190  is contacting a surface, such as the surface of the host device  90 . The detection can be based on movement of the tip  190  relative to the housing  110 . Accordingly, the force sensor  192  can be directly or indirectly connected to both the tip  190  and the housing  110  to detect relative motion there between. The force sensor  192  can include a component that converts mechanical motion of the tip  190  into an electric signal. The force sensor  192  can include one or more contact sensors, capacitive sensors, touch sensors, strain gauges, cameras, piezoelectric sensors, pressure sensors, photodiodes, and/or other sensors. The force sensor  192  can detect both the presence and magnitude of a force. 
     In use, a user may manipulate the stylus  100  and apply a force to a surface of the host device  90 . A corresponding reaction force may be transferred through the tip  190  of the stylus  100  connected to an electromechanical coupling and to the force sensor  192  of the stylus  100 . The force sensor  192 , or a portion thereof, may deform in response which may be measured and used to estimate the applied force. The force sensor  192  can be used to produce a non-binary output that corresponds to the applied force. For example, the force sensor  192  can be used to produce an output that represents a magnitude that varies in accordance with a variable amount of applied force. 
     A touch sensor  200  can be provided to detect contact by a user on a grip region of the housing  110  of the stylus  100 . The touch sensor  200  can include a capacitive touch sensor, such as a self-capacitance sensor. As described further herein, the touch sensor  200  can include multiple sensing elements, such as conductive electrodes, to detect contact and changes in contact at multiple locations. 
     As further shown in  FIG. 2 , the stylus  100  can include a controller  160  and a non-transitory storage medium  162 . The non-transitory storage medium  162  can include, for example, a magnetic storage medium, optical storage medium, magneto-optical storage medium, read-only memory, random access memory, erasable programmable memory, flash memory, or combinations thereof. According to some embodiments, the controller  160  can execute one or more instructions stored in the non-transitory storage medium  162  to perform one or more functions. 
     As further shown in  FIG. 2 , the stylus  100  can include a power source  164 , such as one or more batteries and/or power management units. The stylus  100  can include components for charging the power source  164 , such as a power module  166 . The power module  166  can include one or more components for receiving and/or transmitting power wirelessly (e.g., inductively), for example from the host device  90 . 
     The stylus  100  can include a communication component (not shown) for communicating with the host device  90  and/or another device. The communication component can include one or more wired or wireless components, WiFi components, near field communication components, Bluetooth components, and/or other communication components. The communication component can include one or more transmission elements, such as one or more antennas. Alternatively or in combination, the communication component can include an interface for a wired connection to the host device  90  and/or another device. 
     The stylus  100  can include other components including, but not limited to, displays, sensors, switches (e.g., dome switches), buttons, voice coils, and/or other components. The stylus  100  can detect environmental conditions and/or other aspects of the operating environment of the stylus  100  with an environmental sensor such as an ambient light sensor, proximity sensor, temperature sensor, barometric pressure sensor, moisture sensor, and the like. The stylus  100  can include a haptic feedback component that provides haptic feedback with tactile sensations to the user. The haptic feedback component can be implemented as any suitable device configured to provide force feedback, vibratory feedback, tactile sensations, and the like. For example, in one embodiment, the haptic feedback component may be implemented as a linear actuator configured to provide a punctuated haptic feedback, such as a tap or a knock. The stylus  100  can detect motion characteristics of the stylus  100  with a motion sensor such as an accelerometer, a gyroscope, a global positioning sensor, a tilt sensor, and so on for detecting movement and acceleration of the stylus  100 . The stylus  100  can detect biological characteristics of the user manipulating the stylus with a biosensor that detects skin temperature, heart rate, respiration rate, blood oxygenation level, blood volume estimates, blood pressure, or a combination thereof. The stylus  100  can quantify or estimate a property of an object nearby or otherwise external to the stylus  100  with a utility sensor such as magnetic field sensors, electric field sensors, color meters, acoustic impedance sensors, pH level sensor, material detection sensor, and so on. Such data may be used to adjust or update the operation of the stylus  100  and/or may communicate such data to the host device  90  to adjust or update the operation thereof. 
     The host device  90  can also include components that facilitate operation of the stylus  100 . For example, the host device  90  can include one or more of a processor, a memory, a power supply, one or more sensors, one or more communication interfaces, one or more data connectors, one or more power connectors, one or more input/output devices, such as a speaker, a rotary input device, a microphone, an on/off button, a mute button, a biometric sensor, a camera, a force and/or touch sensitive trackpad, and so on. In some embodiments, a communication interface of the host device  90  facilitates electronic communications between the host device  90  and the stylus  100 . 
     As noted with respect to many embodiments described herein, a stylus configured to provide input capabilities and wireless charging may be constructed in a manner that facilitates these functions in a compact form. Generally and broadly, embodiments described herein provide touch sensing capabilities on an outer surface of the stylus, magnetic components for coupling to a host device, and wireless charging components for receiving power from the host device. One such example stylus is described below with reference to  FIGS. 3 and 4 . However, it may be appreciated that the generalized layout presented therein and described below are merely one example and that other embodiments can be implemented in different ways. 
       FIGS. 3 and 4  depict various components of a stylus  100  in exploded views. To facilitate an understanding of the interoperation and assembly of the various components of the stylus  100 ,  FIGS. 3 and 4  are provided, showing an exploded view of the stylus  100  (e.g.,  FIG. 3 ) and an exploded view of internal components of the stylus  100  (e.g.,  FIG. 4 ). 
     Referring to  FIG. 3 , the stylus  100  of the illustrated embodiment includes a housing  110 . The housing  110  is hollow. The housing  110  may take various forms to facilitate convenient, familiar, and comfortable manipulation or the stylus  100  by a user. In the illustrated example, the housing  110  has the general form of a writing instrument, such as a pen or a pencil. The housing  110  is generally cylindrical with a glass member  180  providing a flat exterior surface on a side thereof. The housing  110  can be formed from plastics, metals, ceramics, laminates, glass, sapphire, wood, leather, synthetic materials, or any other material or combination of materials. The glass member  180  can be formed from alumina silicate glass, soda lime, borosilicate, and the like, and combinations thereof. 
     The housing  110  can be configured to connect or be bonded to a cap  198  at an end of the housing  110 . The cap  198  may be configured to provide a cosmetic end to the housing  110  of the stylus  100 . The cap  198  forms a substantially continuous external surface with the housing  110  when attached to the housing  110 . The cap  198  may be formed from any suitable material, such as, but not limited to, metal, plastic, glass, ceramic, sapphire, and the like or combinations thereof. In many cases, the cap  198  is formed from the same material as the housing  110 , although this is not required. In some embodiments, the cap  198  may be configured, entirely or partially, as a signal diffuser to diffuse an infrared signal or another optical signal, such as a multi-color light-emitting diode. In other cases, the cap  198  may be configured, entirely or partially, as an antenna window, allowing for wireless communications and/or electric fields to pass there through. 
     In the illustrated embodiment, the housing  110  tapers at one end. The tapered end of the housing  110  is identified in the figure as the tapered end  110   a . As illustrated, the tapered end  110   a  may be formed integrally with the housing  110 . In other embodiments, the tapered end  110   a  is a separate piece from the housing  110 . The glass member  180  can extend into the tapered end  110   a . A tip  190  is partially disposed within the tapered end  110   a . Other portions of the tip  190  are attached, either permanently or removably, to the end of the tapered end  110   a  from the exterior thereof. The tip  190  generally takes a conical shape, however such a shape is not required of all embodiments. The tip  190  may be configured to removably or permanently engage with a portion of a coordination engine assembly (described in detail below) disposed within the housing  110 . The tip  190  may be configured to contact an input surface of an electronic device. 
     Referring now to  FIG. 4 , an internal assembly  400  can be provided for insertion into the housing  110  during assembly.

The tip  190  can be connected to the internal assembly through the tapered end  110   a  of the housing  110  after the internal assembly  400  is inserted and/or secured within the housing  110 . 
     Referring now to  FIG. 4 , a wireless power receiver  450  can be provided within a frame  402 . The wireless power receiver  450  can be positioned to avoid interference and/or blocking of wireless signals to the wireless power receiver  450 . A front magnet  448  and a rear magnet  498  are positioned on opposite sides of the wireless power receiver  450 . 
     The stylus  100  can include a touch sensor  200  for detecting touch input from a user. The touch sensor of  FIG. 4  is shown in a flat configuration for purposes of illustration. It will be understood that, when assembled, the touch sensor  200  is wrapped about at least a portion of the frame  402 , and the frame  402  with the touch sensor  200  is inserted into the housing  110 . The touch sensor  200  can be a capacitive touch sensor that extends along at least a portion of a length of the stylus  100  when assembled. The touch sensor  200  can include multiple sensing elements distributed along the length and width thereof so that touch input can be detected at various locations when the stylus is assembled. 
     As further shown in  FIG. 4 , an antenna assembly  324  can be provided for wireless communication. The antenna assembly  324  can include an antenna that protrudes beyond an end of the frame  402  and is not covered by the frame  402 . Additionally or alternatively, the antenna of the antenna assembly  324  can be aligned with a window in the frame  402 . 
     The front assembly  410  can include a coordination engine assembly  346  for detecting force-based inputs at the tip  190 , as discussed further herein. The coordination engine assembly  346  can be inserted within the frame  402 . The coordination engine assembly  346  can include components for detecting forces and orientations of the stylus, such as a force-sensitive structure. In some embodiments, the force-sensitive structure includes an element that exhibits an electrically-measurable property that changes as a function of the magnitude of force applied. In one example, a strain-sensitive electrode may be coupled to a portion of the force-sensitive structure. In other embodiments, the deflection of the force-sensitive structure can be measured in another manner such as with, but not limited to: optical sensors; acoustic sensors; resonance sensors; piezoresistive sensors; and so on. 
     Referring now to  FIGS. 5 and 6 , use of the stylus with a host device can provide an interface for wireless charging for the stylus. As shown in  FIG. 5 , a wireless power receiver  450  within the housing of the stylus  100  and multiple stylus magnets  448  and  498  positioned on opposite sides of the wireless power receiver  450 . The wireless power receiver  450  and the multiple stylus magnets  448  and  498  can be positioned on a same radial side of the stylus  100  as the glass member  180  so that magnetic coupling occurs on the side that is defined by the glass member  180 . It will be understood that additional stylus magnets can optionally be included, and that the stylus magnets can be provided in other arrangements, such as on a same longitudinal side of the wireless power receiver  450 . 
     The stylus magnets  448  and  498  provide magnetic coupling to corresponding host magnets  48  and  98  of the host device  90 . As further shown in  FIG. 5 , a wireless power transmitter  58  is provided by the host device  90 . The host magnets  48  and  98  can be positioned on opposite sides of the wireless power transmitter  58 . The wireless power transmitter  58  and the host magnets  48  and  98  can be positioned so that, when the stylus magnets  448  and  498  are aligned with the host magnets  48  and  98 , the wireless power receiver  450  is aligned with the wireless power receiver  450  of the host device  90 . It will be understood that additional host magnets can optionally be included, and that the host magnets can be provided in other arrangements, such as on a same longitudinal side of the wireless power transmitter  58 . 
     The magnetic coupling can maintain the alignment during a charging session. The glass member  180  can facilitate secure coupling to an engagement surface  14  of the host device  90 . For example, the host device  90  can provide the engagement surface  14  with another flat surface or other complementary shape to facilitate physical contact of the opposing surfaces and maintain close proximity to the wireless power transmitter  58  and the wireless power receiver  450 . It will be understood that other surface shapes and features are contemplated to facilitate contact and engagement of the stylus to the host device. For example, the surfaces (e.g., of the glass member  180  and/or the engagement surface  14  of the host device  90 ) can be flat, curved, concave, convex, undulating, stepped, tapered, or another shape to provide engagement. 
     The inclusion of the glass member  180  provides engagement with the host device and transmission of wireless power. Additionally, the glass member  180  provides a durable surface that is resistant to wear, scratching, and infiltration of debris. For example, the glass member  180  can provide a relatively rigid and non-porous surface that does not accept infiltration of debris occurring at the interface between the stylus  100  and the host device  90 . As such, contact and rubbing occurring during coupling can resist degradation of the stylus at the glass member  180 . This is particularly beneficial where the magnets are included in the stylus, as such magnets can attract metallic debris on the surface of the stylus, which may then be ground into the housing when contacting other surfaces, such as the host device. The glass member  180  can be located over the magnets and resist such infiltration, providing a more aesthetically pleasing appearance despite extensive use of the stylus. Additionally, the glass member  180  can be manufactured with precision to provide a shape and surface features that have fewer surface deviations than would occur with coating layers. 
     Referring now to  FIG. 7 , the stylus  100  can support handling and operation by a user. In particular, the stylus  100  can receive inputs from a user at a location of the user&#39;s grip.  FIG. 7  illustrates a stylus  100 , according to some embodiments of the subject technology. According to some embodiments, for example as illustrated in  FIG. 7 , the stylus  100  can include a housing  110  and a glass member  180  that together provides an outermost cover along at least a portion of the length of the stylus  100 . A user can grip the stylus  100  at a user grip region  104  during use of the stylus  100 . The user grip region  104  can be located at a natural grip location, so that the user can provide inputs at the same location that is grasped during normal use of the stylus  100 . For example, the user grip region  104  can be located an outer surface of the housing  110  and the glass member  180 . The user grip region  104  can be near the tip  190  of the stylus  100 . For example, the location of the user grip region  104  can be a distance from the tip  190  that is less than a half, a third, or a quarter of the total length of the stylus  100 . At the user grip region  104 , components of the stylus  100  can be positioned to receive tactile input from the user. For example, the user grip region  104  can be a portion of the housing  110 . Alternatively or in combination, the user grip region  104  can include an input component set within the housing  110 , such as a button, switch, knob, lever, and/or another input component. According to some embodiments, a marker can be provided (e.g., on the glass member  180 ) as an indicator for the location of the user grip region  104 . The marker can be flush with neighboring portions of the outer surface, such that it can be seen but provide the same tactile features as other portions of the housing  110 . Alternatively or in combination, the marker can provide a protrusion, recess, or texture that provides surface features that are different from adjacent portions of the housing  110 . 
     Referring now to  FIG. 8 , the glass member can form a portion of an outer periphery of the stylus. For example, as shown in  FIG. 8 , the housing  110  can define, in cross-section, a continuously curved outer surface terminating in housing edges  130  at each of opposing shoulders  114  that are separated from each other. The glass member  180  can be positioned on a side of the housing  110 , for example between the shoulders  114 . While the housing  110  defines a curved outer periphery of the stylus  100 , the glass member  180  can defined a flat outer periphery of the stylus  100 . The flat portion of the glass member  180  can be used to stabilize the stylus  100  against another surface, such as a working surface, a host device, and/or a charging station, as discussed further herein. It will be understood that other surface shapes and features can be provided on the glass member  180  and/or the housing  110 . 
     An outer surface  182  of the glass member  180  can be flush with the housing edges  130  where the outer surface of the housing  110  terminates and forms the shoulders  114 . Accordingly, the glass member  180  can provide a smooth transition from its outer surface to the outer surface of the housing  110 . While the cross-sectional shapes of the glass member  180  and the housing  110  can differ, the transition can be formed with neither item protruding radially beyond the other at the region of transition. 
     Where the glass member  180  is nested within the housing  110 , sidewalls  186  of the glass member  180  can abut and/or oppose the shoulders  114  of the housing  110 . An inner surface  184 , opposite the outer surface  182 , of the glass member  180  can abut and/or oppose a support surface  112  of the housing. The support surface  112  can extend between the base of each shoulder  114 . The support surface  112  can have a shape that is complementary to the shape of the inner surface  184  of the glass member  180 . 
     One of more aesthetic features can be provided to enhance the visual appearance of the stylus. For example, a visual feature can be provided on the glass member  180  and/or the housing  110  for viewing through the glass member  180 . Such visual features can include one or more of a coating, printing, paint, ink, design, etching, carving, deposited material, or other viewable feature. Such visual features can be provided on a surface of the glass member  180  and/or the housing  110 . For example, a visual feature can be provided on the outer surface  182 , the inner surface  184 , and/or the sidewalls  186  of the glass member  180 . By further example, a visual feature can be provided on the shoulders  114  and/or the support surface  112  of the housing  110 . Such features can be viewed through the glass member  180 . Furthermore, such features can be protected from wear and damage by the glass member  180 . 
     Referring now to  FIG. 9 , the glass member can be positioned over a gap in the housing. For example, as shown in  FIG. 9 , the housing  110  can include ledges  116  that extend toward each other and define a gap  118  there between. It will be understood that the ledges  116  can be separate portions of a continuous ledge that extends about the gap  118 . The glass member  180  can be positioned on the ledges  116  and above the gap  118 . The glass member  180  can provide a view to components within the housing  110 . Additionally or alternatively, the glass member  180  can include one or more visual features that obscure a view to components within the housing  110 . As shown in  FIG. 9 , the glass member  180  can be nested within the housing  110 , with an outer surface  182  of the glass member  180  being flush with the housing edges  130  where the outer surface of the housing  110  terminates and forms the shoulders  114 . 
     Referring now to  FIG. 10 , the glass member can rest on a top surface of the housing. For example, as shown in  FIG. 10 , the housing  110  can include ledges  116  that extend toward each other and define a gap  118  there between. The glass member  180  can be positioned on the ledges  116  and above the gap  118 . As shown in  FIG. 10 , the glass member  180  need not be nested within the housing  110 . The outer surface  182  of the glass member  180  can be flush with the housing edges  130  formed at a transition to the ledges  116 . The curvature of the outer surface  182  of the glass member  180  can match the curvature of the housing  110  at the housing edges  130 . Elsewhere, the outer surface  182  of the glass member  180  can be planar or flat. 
     Referring now to  FIG. 11 , the glass member can provide a view to a display or other visual element within the housing. For example, as shown in  FIG. 11 , the housing  110  can contain a display  120  that is supported on the frame  402 . The gap  118  can separate the glass member  180  from the display  120 , or no gap can be present. The display  120  can be viewed from outside the stylus through the glass member  180 . The display  120  can be a visual output element, such as a liquid crystal display screen, electronic ink (e-ink) screen, organic light emitting diode (OLED) or diodes, light emitting diode or diodes, or the like. Where the display  120  provides a curvature, a flexible OLED screen can optionally be provided to conform to the desired shape. The display  120  can include a plate having perforations for selective illumination there through for displaying a pattern or design. Other components of the stylus  100 , such as a touch sensor, can be positioned radially between the display  120  and the glass member  180 . Additionally or alternatively, the display  120  can include or be placed adjacent to a diffuser or other element for modifying the visual output of the display  120 . 
     Referring now to  FIGS. 12 and 13 , the stylus  100  can receive tactile input from the user at the user grip region  104  with a touch sensor  200 .  FIG. 12  illustrates a side sectional view of the stylus  100  taken along line A-A of  FIG. 7 , according to some embodiments of the subject technology.  FIG. 13  illustrates a front sectional view of the stylus  100  taken along line B-B of  FIG. 7 , according to some embodiments of the subject technology. As shown in  FIGS. 12 and 13 , the stylus  100  can include a front magnet  448  that is within the frame  402 . A similar arrangement can be provided for the rear magnet  498  discussed above. The position of the magnets on the same radial side as the glass member  180  allows engagement with the host device to be provided against the glass member  180 , rather than the housing  110 . 
     As shown in  FIG. 12 , the touch sensor  200  can include multiple sensing elements  210  distributed along a longitudinal length of the stylus  100  at the grip region  104 . For example, the sensing elements  210  shown in  FIG. 12  are distributed longitudinally so that each sensing element  210  of a given column faces outwardly at a different portion of the housing  110  and/or the glass member  180 . The touch sensor  200  can include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10 sensing elements  210  along a longitudinal length. The distribution of sensing elements  210  provides independent sensing capabilities at multiple locations along the longitudinal length of the stylus  100  at the grip region  104 . 
     As shown in  FIG. 13 , the touch sensor  200  can be positioned radially between a frame  402  and the housing  110  and/or the glass member  180  of the stylus  100 . In addition, an elastic insert  122  can be positioned between the touch sensor  200  and the frame  402 . With the elastic insert  122  positioned radially between the frame  402  and the touch sensor  200 , the elastic insert  122  can bias the touch sensor  200  radially outwardly against the housing  110  and/or the glass member  180 . 
     The touch sensor  200  can include multiple sensing elements  210  distributed circumferentially. For example, the sensing elements  210  shown in  FIG. 13  are distributed circumferentially so that each sensing element  210  of a given row faces radially outwardly at a different portion of the housing  110  and/or the glass member  180 . The touch sensor  200  can include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more than 10 sensing elements  210  about a circumference. The distribution of sensing elements  210  provides independent sensing capabilities at multiple locations about the circumference of the stylus  100  at the grip region  104 . 
     As shown in  FIG. 13 , the housing  110  and/or the glass member  180  can be curved along some or all of an inner and/or outer surface. The housing  110  and/or the glass member  180  can be flat along some or all of an inner and/or outer surface. The touch sensor  200  can generally conform to the outer shape of the frame  402  and/or the elastic insert  122 . Additionally or alternatively, the touch sensor  200  can generally conform to the inner shape of the housing  110  and/or the glass member  180 , which may include flat and/or curved surfaces. Where the touch sensor  200  does not directly contact the inner surface of the housing  110  and/or the glass member  180 , the touch sensor  200  can maintain a constant distance with respect the most adjacent portions of the housing  110  and/or the glass member  180 , so that the presence of a finger on the housing  110  and/or the glass member  180  is reliably detectable by the touch sensor  200 . 
     As shown in  FIG. 14 , the touch sensor  200  can extend at least partially within a grip region  104  of the stylus  100  on a longitudinal side of the wireless power receiver  450 . For example, the touch sensor  200  can extend along the grip region  104 . The touch sensor  200  and the wireless power receiver  450  can be positioned along the longitudinal axis to have no overlapping portions. The touch sensor  200  can have a length that is within a length of the glass member  180 . 
     As shown in  FIG. 15 , the stylus  100  can include multiple touch sensors  200  on opposite sides of the wireless power receiver  450 . Each of the multiple touch sensors  200  can extend within a different portion of the housing  110 . The touch sensors  200  can be spaced apart from each other. At least one of the touch sensors  200  can extend along the grip region  104 . The touch sensors  200  and the wireless power receiver  450  can be positioned along the longitudinal axis to have no overlapping portions. Gestures detected by the separate touch sensors  200  can be interpreted as different user inputs according to preprogrammed functions to be performed by the stylus  100  and/or a host device upon detection of the user gestures. One or more of the touch sensors  200  can have a length that is within a length of the glass member  180 . 
     As shown in  FIG. 16 , a touch sensor  200  can be positioned to extend across the wireless power receiver  450 . In this configuration, the wireless power receiver  450  can be configured to operate through the touch sensor  200  and the glass member  180 . In particular, charging can be performed when the stylus is not in use, and the touch sensor  200  can be deactivated during a charging session. The touch sensor  200  can have a length extends beyond a length of the glass member  180 . 
     The touch sensor  200  can be provided to cause the stylus and/or the host device to perform one or more functions. While certain examples are provided herein, it will be appreciated that any function of the stylus and/or the host device can be performed according to preprogrammed features of the stylus and/or the host device. The touch sensor  200  can be used to detect where and whether the user is gripping the stylus  100 . The touch sensor  200  can be used to change, select, and/or display one or more settings of the stylus and/or the host device. For example, the touch sensor  200  can detect gestures and transmit a signal to the host device to change, select, and/or display one or more settings that affect performance of the stylus and/or the host device. The setting can relate to a characteristic (e.g., color, size, width, thickness, shape, etc.) of a marking produced by use of the stylus with the host device 
     The touch sensor  200  can be used to detect a tap, double tap, triple tap, or another tap gesture by the user. For example, as a user applies a finger at the grip region  104 , the stylus  100  can detect the resulting capacitance that is induced in the touch sensor  200 . The user can subsequently lift the finger, and the stylus  100  can detect the resulting capacitance or change in capacitance that is induced in the touch sensor  200 . The user can subsequently return the finger to the grip region  104 , and the stylus  100  can detect the resulting capacitance or change in capacitance that is induced in the touch sensor  200 . The sequence of inputs within a span of time can be interpreted by the stylus  100  as a user&#39;s tap gesture. Additionally or alternatively, the touch sensor  200  can be used to detect a sliding gesture by the user. Multiple sensing elements of the touch sensor  200  along the grip region can be used in concert to detect particular user inputs. Additionally or alternatively, the touch sensor  200  can be used to detect a rolling gesture by the user. The rolling gesture can include movement of a finger about a circumference of the stylus  100  and/or rolling movement of the stylus  100  over a surface, such as a working surface. It will be appreciated that the touch sensor  200  can be used to detect combinations of gestures, including tap gestures, sliding gestures, rotational gestures, and/or other gestures. For example a sequence of different gestures in combination can be interpreted by the stylus  100  as a user&#39;s input. 
     The stylus  100  can be assembled by a process that provides the touch sensor  200  at a grip region  104  of the stylus  100  with the front magnet  448  supported there within. For example, the touch sensor  200  and the elastic insert  122  can be provided in a flat or substantially planar configuration. The elastic insert  122  can be wrapped around the frame  402 . The recesses of the elastic insert can be aligned with protruding features of the frame assembly. The touch sensor  200  can be wrapped around the elastic insert  122 . Next, the assembly including the front frame  402 , the front magnet  448 , the elastic insert  122 , and the touch sensor  200  can be inserted into the housing  110  and near the glass member  180 . Prior to being inserted, the assembly can be oversized such that an outer cross-sectional dimension (e.g. diameter) of the touch sensor  200  is greater than an inner cross-sectional dimension (e.g., diameter) of the housing  110 . Accordingly, as the assembled touch sensor  200  is inserted into the housing  110 , it will be compressed to conform to the inner surface of the housing  110  and/or the glass member  180 . The touch sensor  200  can compress along with the elastic insert  122  when inserted into the housing  110 . While within the housing  110 , the elastic insert  122 , under compression, biases the touch sensor  200  against the inner surface of the housing  110  and/or the glass member  180 . The elastic insert  122  can include one or more of a variety of materials to provide such biasing under compression. For example, the elastic insert  122  can include a foam body, an elastomer, a matrix material, or another material having elastic properties. The elastic insert  122  can include an adhesive for bonding the touch sensor to the frame  402 . For example, the elastic insert  122  can include a pressure-sensitive adhesive that is activated upon compression. 
     Referring now to  FIGS. 17 and 18 , the stylus  100  can provide wireless charging capabilities.  FIG. 17  illustrates a side sectional view of the stylus  100  taken along line C-C of  FIG. 7 , according to some embodiments of the subject technology.  FIG. 17  illustrates a front sectional view of the stylus  100  taken along line D-D of  FIG. 7 , according to some embodiments of the subject technology. As shown in  FIGS. 17 and 18 , the stylus  100  can include a wireless power receiver  450  that is within the housing  110 . The wireless power receiver  450  can be positioned on the same radial side as the glass member  180 . The frame  402  can be of a metallic and/or conductive material that provides adequate structural support and shielding to components housed therein. The wireless power receiver  450  can be positioned near or adjacent to the glass member for electromagnetic power transfer through the glass member  180 . 
       FIGS. 19 and 20  illustrate some of the various operations of a stylus to display information relating to use with a host device. According to some embodiments, a stylus can replicate the display of a representation that is also displayed on the host device. For example, while the interface surface  50  of the host device  90  displays a representation  56 , the stylus  100 , through the glass member  180 , can replicate at least a portion of the representation  56  as another representation  156 . The stylus  100  and/or the host device  90  can estimate what portion of the glass member  180  is between the user and the displayed representation  56 . Such an estimate can be based on the position and/or orientation of the stylus  100  and/or the host device  90 . Corresponding sensors can be provided to perform such estimates. The resulting representation  156  displayed through the glass member  180  can give the appearance of the underlying representation  56  so the user is able to see the portion of the representation  56  that is otherwise blocked from user by the stylus  100 . 
     According to some embodiments, the stylus can display a color, pattern, or other visual feature for output on the host device base on operation of the stylus. For example, a color can be selected. In some example, the stylus  100  can be used to select the color. The stylus  100  can transmit the color to the host device  90 . The host device  90  records the color, and a corresponding signal is communicated to the display of the stylus for display to a user through the glass member  180 . For example, a display beneath the glass member  180  can show one of more selected colors. As shown in  FIG. 20 , the tip  190  of the stylus  100  can be used to contact the interface surface  50  of the host device  90 . A corresponding representation  56  is recorded and displayed on the interface surface  50  at the location of the tip  190 . According to some embodiments, the selected and displayed color can be applied to the representation  56  that is displayed on the host device  90 . Thus, the same color can be displayed through the glass member  180  of the stylus  100  and applied to the representation  56  that is displayed on the host device  90 . 
     While portions of the above description relate to selection of color, it will be recognized that other characteristics, including other visual aspects, can be selected, displayed, and applied. For example, the selection, display, and application can relate to a brightness, opacity, shading, gradient, texture, size, proportion, and/or pattern. 
     Accordingly, the inclusion and arrangement of a glass member at an outer periphery of the stylus facilitates various functions of the stylus while providing structural support and aesthetic features. The glass member facilitates detection of touch input with a capacitive touch sensor within the stylus. The glass member facilitates magnetic coupling with a host device and wireless charging from the host device. The glass member also provides a durable outer surface along a section of the stylus to reduce the effects of wear. The glass member can be provided in a variety of shapes and arrangements that offer aesthetic options and customization for personal preferences. 
     While some embodiments of touch-based input devices disclosed herein relate to styluses, it will be appreciated that the subject technology can encompass and be applied to other input devices. For example, an input device in accordance with embodiments disclosed herein can include a phone, a tablet computing device, a mobile computing device, a watch, a laptop computing device, a mouse, a game controller, a remote control, a digital media player, and/or any other electronic device.

Finally, any combination of separate programs that together implement a software aspect described here is within the scope of the subject disclosure. In some implementations, the software programs, when installed to operate on one or more electronic systems, define one or more specific machine implementations that execute and perform the operations of the software programs. 
     A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network. 
     It is understood that any specific order or hierarchy of blocks in the processes disclosed is an illustration of example approaches. Based upon design preferences, it is understood that the specific order or hierarchy of blocks in the processes may be rearranged, or that all illustrated blocks be performed. Some of the blocks may be performed simultaneously. For example, in certain circumstances, multitasking and parallel processing may be advantageous. Moreover, the separation of various system components in the embodiments described above should not be understood as requiring such separation in all embodiments, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products. 
     The previous description is provided to enable any person skilled in the art to practice the various aspects described herein. Various modifications to these aspects will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other aspects. Thus, the claims are not intended to be limited to the aspects shown herein, but are to be accorded the full scope consistent with the language claims, wherein reference to an element in the singular is not intended to mean “one and only one” unless specifically so stated, but rather “one or more.” Unless specifically stated otherwise, the term “some” refers to one or more. Pronouns in the masculine (e.g., his) include the feminine and neuter gender (e.g., her and its) and vice versa. Headings and subheadings, if any, are used for convenience only and do not limit the subject disclosure. 
     The predicate words “configured to”, “operable to”, and “programmed to” do not imply any particular tangible or intangible modification of a subject, but, rather, are intended to be used interchangeably. For example, a processor configured to monitor and control an operation or a component may also mean the processor being programmed to monitor and control the operation or the processor being operable to monitor and control the operation. Likewise, a processor configured to execute code can be construed as a processor programmed to execute code or operable to execute code 
     A phrase such as an “aspect” does not imply that such aspect is essential to the subject technology or that such aspect applies to all configurations of the subject technology. A disclosure relating to an aspect may apply to all configurations, or one or more configurations. A phrase such as an aspect may refer to one or more aspects and vice versa. A phrase such as a “configuration” does not imply that such configuration is essential to the subject technology or that such configuration applies to all configurations of the subject technology. A disclosure relating to a configuration may apply to all configurations, or one or more configurations. A phrase such as a configuration may refer to one or more configurations and vice versa. 
     The word “example” is used herein to mean “serving as an example or illustration.” Any aspect or design described herein as “example” is not necessarily to be construed as preferred or advantageous over other aspects or design 
     All structural and functional equivalents to the elements of the various aspects described throughout this disclosure that are known or later come to be known to those of ordinary skill in the art are expressly incorporated herein by reference and are intended to be encompassed by the claims. Moreover, nothing disclosed herein is intended to be dedicated to the public regardless of whether such disclosure is explicitly recited in the claims. No claim element is to be construed under the provisions of 35 U.S.C. § 112, sixth paragraph, unless the element is expressly recited using the phrase “means for” or, in the case of a method claim, the element is recited using the phrase “step for.” Furthermore, to the extent that the term “include,” “have,” or the like is used in the description or the claims, such term is intended to be inclusive in a manner similar to the term “comprise” as “comprise” is interpreted when employed as a transitional word in a claim.
