Abstract
Techniques are described for optical sightline tracking in a wearable system. Embodiments include a wearable structure that includes at least one integrated illuminator and at least one integrated imaging array. Each illuminator and imaging array is disposed in the periphery of an eye of a user wearing the structure. From the peripheral viewpoint, embodiments measure a three-dimensional origin point of one or both eyes and can compute angular coordinate measurements for one or both eyes based on the imaging to indicate the direction in which the user's eyes are looking (a sightline). Embodiments can track changes in the sightline to support various applications, such as positioning of display of virtual objects in virtual or augmented reality environments. Some embodiments can also use the obtained imagery for biometric verification and/or identification, detection of changes in pupillary response, etc.
