Abstract: A wearable electronic device including a housing that is worn by a user and a SMI sensor contained within the housing. The SMI sensor may include an emitter that outputs coherent light toward the skin of a user when the housing is worn by the user. The SMI sensor may also include a detector that detects a portion of the coherent light reflected towards the sensor and generates electrical signals that indicate displacements of the skin based on the portion of coherent light received at the detector. The housing may include a transmitter that is operatively coupled with the SMI sensor and is configured to transmit physiological data to a receiving device based on electrical signals output from the SMI sensor.

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: A wearable display system includes a housing, a display module positioned within the housing and including a lens and a display panel, and a seal extending between the housing and the display module.

In one aspect, the seal includes first and second segments with generally linear configurations and a third segment with an arcuate configuration that is positioned between the first and second segments. In another aspect, the seal includes a first portion with an arcuate configuration and a second portion with a linear configuration and a bellows portion. In another aspect, the seal includes corrugations to facilitate controlled deformation of the seal during relative movement of the display module.

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.

Abstract: A system may include finger devices. A touch sensor may be mounted in a finger device housing to gather input from an external object as the object moves along an exterior surface of the housing. The touch sensor may include capacitive sensor electrodes. Sensors such as force sensors, ultrasonic sensors, inertial measurement units, optical sensors, and other components may be used in gathering finger input from a user. Finger input from a user may be used to manipulate virtual objects in a mixed reality or virtual reality environment while a haptic output device in a finger device provides associated haptic output. A user may interact with real-world objects while computer-generated content is overlaid over some or all of the objects. Object rotations and other movements may be converted into input for a mixed reality or virtual reality system using force measurements or other sensors measurements made with the finger devices.
