Abstract: A head-mounted wearable device provides many functions to a user. The functions may be provided based in part on whether the device is being worn (donned) or not worn (doffed). Force sensing resistors in the device provide output indicative of forces associated with wearing the device. A time series of values indicative of the magnitude of a force may be determined. An increase or decrease in force values measured at different times may indicate that the device has been donned or doffed, respectively. If a subsequent force value does not differ substantially from a previous force value, this may indicate that the device has remained donned or doffed.

Abstract: A user interface for a head-mounted wearable device provides many functions to a user. Information about whether the device is being worn (donned) or not worn (doffed) may be acquired in several ways. Force sensing resistors in the device may provide output indicative of the pressure associated with wearing the device. Output from a bone conduction (BC) microphone may be analyzed to determine if the device is in use. Piezoelectric BC speakers typically used to present audio output to a wearer provide changes in voltage corresponding to a change in pressure associated with wearing the device. A BC speaker may emit a signal that is detected by the BC microphone, with changes in the signal strength being used to determine if the device is donned or doffed.

Abstract: A head-mounted wearable device (HMWD) with a form factor of eyeglasses incorporates hinges between a front frame and temples. The hinges provide a fully enclosed passage for a flexible printed circuit (FPC). The FPC allows electrical connectivity between devices in the front frame and in the temple. The hinge includes a cam device that provides a biasing force that allows the temples to remain in one of four configurations: closed, transit, neutral, and maximum neutral. When in the transit configuration the biasing force provided by the cam device tends to move the temples towards the closed configuration. When in the maximum neutral configuration the biasing force provided by the cam device tends to move the temples towards the neutral configuration. During use, this biasing of the temples provides a gentle clamping force that assists in maintaining the HMWD on the user's head.

Abstract: A head-mounted wearable device (HMWD) may be fashioned that includes temples that pass near each ear of the user. To accommodate different head shapes and sizes, a head contact piece may be mounted to the temple. Head contact pieces with different profiles may be used to improve user comfort, aid in retaining the HMWD on the user's head, improve performance of output devices such as bone conduction speakers, and so forth.

Abstract: A head-mounted wearable device (HMWD) includes a bone conduction speaker (BCS) to provide audio output to a user wearing the HMWD. The BCS may be mounted within a recess of a temple of the HMWD. During wear a portion of the BCS is in physical contact with a head of the user. In one implementation, a head contact piece may be mounted to the side of the BCS that is proximate to the head. The head contact piece is contoured to maximize the contact area with the head, and may have a cross section that is approximately wedge shaped, with a thicker portion of the wedge proximate to the front of the HMWD. The BCS may include low damping elements to provide protection to the BCS from damage and improve performance, as well as high damping elements to reduce the transfer of vibrations from the BCS to the temple.

Abstract: A head-mounted wearable device (HMWD) may incorporate bone conduction speakers (BCS) to generate audio output that is perceptible to a wearer. Due to the mechanical connection between the BCS and the rest of the device, when the output amplitude of the BCSs is too great, the air-conducted audio “leaks” and may be heard by other people. This leakage may result in eavesdropping by, or generate a nuisance to, those other people. The noise level in the environment around the HMWD is determined and used to dynamically adjust the amplitude of the audio output generated by the BCS. This adjustment improves the comfort and intelligibility of the audio output to the wearer while minimizing audio leakage to the surrounding environment.

Abstract: A head-mounted wearable device (HMWD) incorporates a visual indicator device (VID) that provides a visual cue to a wearer about activity of the HMWD. The VID may be positioned in a frame of the HMWD to be within an upper portion of a wearer's field of view during wear. The VID may provide a diffuse illumination that is visible to the wearer but does not obtrusively illuminate the face of the wearer, resulting in the visual indicator being unobtrusive to bystanders. Activation, intensity, color, blink rate, or other characteristics of the visual indicator may be used to provide the wearer with information. For example, the VID may illuminate with a solid color while a microphone on the HMWD is active, or blink while the microphone is muted. Input from an ambient light sensor may be used to adjust the operation of the VID during operation.

A temple may incorporate a bone conduction speaker (BCS) to provide audio output to the user. During wear, a portion of the BCS is in physical contact with a head of the user to transfer the vibrations from the BCS to the user. To accommodate different head shapes and sizes, a head contact piece may be mounted to the BCS. The user may add, remove, or swap the head contact piece from an assortment of such pieces to find a profile that is comfortable to the wearer and improves performance of the BCS. The head contact piece may be magnetically affixed, allowing for easy changeout.
