Abstract: A head-mounted device or other electronic device may emit an alternating-current magnetic field. A wireless controller may have alternating-current magnetometers for monitoring the alternating-current field. The wireless controller may also have an accelerometer for measuring the orientation of the controller relative to the Earth's gravity and a direct-current magnetometer for measuring the orientation of the controller relative to the Earth's magnetic field. The alternating-current magnetometers may be three-coil magnetometers located at different locations in a controller housing. Using data from the alternating-current magnetometers, the direct-current magnetometer, the accelerometer, and/or other sensors, the wireless controller can determine the position and orientation of the wireless controller. This information can be wirelessly transmitted to the head-mounted device to control the head-mounted device.

Abstract: A head-mounted device may have a display with first and second pixel arrays that display content for a user. A head-mounted support structure in the device supports the pixel arrays on the head of the user. A left positioner may be used to position a left lens module that includes a left lens and the first pixel array. A right positioner may be used to position a right lens module that includes a right lens and the second pixel array. Sensing circuitry such as proximity sensing circuitry may be used to detect relative positions between the left and right lens modules and facing surfaces of a user's nose while the user is wearing the head-mounted support structure. Control circuitry may adjust the positions of the left and right lens modules using interpupillary distance information for the user and using information from the sensing circuitry.

Abstract: A system may include one or more finger devices that gather input from a user's fingers. A finger device may include one or more self-mixing interferometric proximity sensors that measure a distance to the user's finger. The proximity sensor may measure changes in distance between the proximity sensor and a flexible membrane that rests against a side portion of the user's finger. The self-mixing interferometric proximity sensor may include a laser and a photodiode. In some arrangements, a single laser driver may drive the lasers of multiple self-mixing proximity sensors using time-multiplexing. The self-mixing proximity sensor may operate according to a duty cycle. Interpolation and stitching may be used to determine the total displacement of the user's finger including both the on periods and off periods of the self-mixing proximity sensor.

Abstract: A wristband can comfortably secure an electronic device, such as a wristwatch or fitness/health tracking device, to a wrist of a user. The wristband can include a number of magnets that allow the wristband to be magnetically coupled to itself when folded over or when separate band portions are overlapping. The magnets can include a polymer mixed with a magnetic material to provide magnetic properties and flexibility. The magnets can be joined together by a continuous support structure that extends through opposing pairs of the magnets. The support structure can provide substantial and ability as well as tensile strength. The magnets and the support structure can be surrounded by a flexible cover to protect the components within.

Abstract: A finger device may be worn on a user's finger and may serve as a controller for a head-mounted device or other electronic device. The finger device may have a housing having an upper housing portion that extends across a top of the finger and first and second side housing portions that extend down respective first and second sides of the finger. Displacement sensors in the side housing portions may measure movements of the sides of the finger as the finger contacts an external surface. To account for variations in skin compliance, the finger device and/or the electronic device may store calibration data that maps displacement values gathered by the displacement sensors to force values. The calibration data may be based on calibration measurements gathered while the user's finger wearing the finger device contacts a force sensor in an external electronic device.

Abstract: A head-mountable device can include multiple microphones for directional audio detection. The head-mountable device can also include a speaker for audio output and/or a display for visual output. The head-mountable device can be configured to provide visual outputs based on audio inputs by displaying an indicator on a display based on a location of a source of a sound. The head-mountable device can be configured to audio outputs based on audio inputs by modifying an audio output of the speaker based on a detected sound and a target characteristic. Such characteristics can be based on a direction of a gaze of the user, as detected by an eye sensor.

Abstract: An input device includes an enclosure defining a three-dimensional input space and one or more self-mixing interferometry sensors coupled to the enclosure and configured to produce a self-mixing interferometry signal resulting from reflection of backscatter of emitted light by a body part in the three-dimensional input space. In various examples, movement of the body part may be determined using the self-mixing interferometry signal, which may in turn be used to determine an input. In some examples, a body part displacement or a body part speed and an absolute distance to the body part may be determined using the self-mixing interferometry signal and used to determine an input. In a number of examples, multiple self-mixing interferometry sensors may be used and the movement may be determined by analyzing differences between the respective produced self-mixing interferometry signals.
