Abstract:
1. A method, comprising: initiating, by a head-mountable device, a camera application; receiving, by the head-mountable device, first audio data that is generated by an audio sensor associated with the head-mountable device; detecting that the first audio data includes a speech command that corresponds to a video recording process; in response to the speech command, initiating the video recording process via the camera application, wherein the video recording process comprises capturing second audio data and video data and storing the second audio data and the video data to a video file; emitting infrared (IR) radiation from an IR radiation source associated with the head-mountable device toward a target location; receiving, at an IR sensor associated with the head-mountable device, reflected IR radiation, wherein the reflected IR radiation comprises IR radiation emitted by the IR radiation source and reflected from the target location; generating time-varying amplitude data for the reflected IR radiation received at the IR sensor; determining, based on the time-varying amplitude data, a sequence of viewing states of the target location; and during the video recording process:
