摘要： Examples relating to using non-visual feedback to alert a viewer of a display that a visual change has been triggered are disclosed. One disclosed example provides a method comprising using gaze tracking data from a gaze tracking system to determine that a viewer changes a gaze location. Based on determining that the viewer changes the gaze location, a visual change is triggered and non-visual feedback indicating the triggering of the visual change is provided to the viewer. If a cancel change input is received within a predetermined timeframe, the visual change is not displayed. If a cancel change input is not received within the timeframe, the visual change is displayed via the display.

摘要： Embodiments that relate to determining gaze locations are disclosed. In one embodiment a method includes shining light along an outbound light path to the eyes of the user wearing glasses. Upon detecting the glasses, the light is dynamically polarized in a polarization pattern that switches between a random polarization phase and a single polarization phase, wherein the random polarization phase includes a first polarization along an outbound light path and a second polarization orthogonal to the first polarization along a reflected light path. The single polarization phase has a single polarization. During the random polarization phases, glares reflected from the glasses are filtered out and pupil images are captured. Glint images are captured during the single polarization phase. Based on pupil characteristics and glint characteristics, gaze locations are repeatedly detected.

摘要： Techniques for implementing an integrative interactive space are described. In implementations, video cameras that are positioned to capture video at different locations are synchronized such that aspects of the different locations can be used to generate an integrated interactive space. The integrated interactive space can enable users at the different locations to interact, such as via video interaction, audio interaction, and so on. In at least some embodiments, techniques can be implemented to adjust an image of a participant during a video session such that the participant appears to maintain eye contact with other video session participants at other locations. Techniques can also be implemented to provide a virtual shared space that can enable users to interact with the space, and can also enable users to interact with one another and/or objects that are displayed in the virtual shared space.
