Abstract: 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.

Abstract: This document describes techniques and apparatuses for implementing an object-detecting backlight unit for a display device. An object-detecting backlight unit includes two or more light sources configured to provide light to a display to form an image, and a light sensor configured to receive reflected light when an object is near the display and determine that the reflected light originated from a region of the display. The reflected light is caused by light from the image reflecting off of the object back towards the display. The backlight unit is configured to detect a position of the object based on the region of the display from which the reflected light originated.

Abstract: Embodiments are disclosed herein related to the avoidance of undesirable optical effects in a liquid crystal display used with a touch-sensitive display input device. For example, one embodiment provides a user interface comprising a body, a light source disposed within the body, and a liquid crystal display configured to create an image displayable on one or more display surfaces coupled to the body. The user interface device further includes a light delivery system positioned optically between the light source and the liquid crystal display to deliver light produced by the light source to the liquid crystal display. The light delivery system comprises a light exit surface spaced from the liquid crystal display to form a gap positioned between the light exit surface of the light delivery system and the liquid crystal display.

Abstract: This document describes embodiments of a low-latency touch-input device. The low-latency touch-input device receives writing as input to the device and temporarily displays the writing on a physical layer that overlays a touchscreen display of the device. The writing is displayed instantaneously on the physical layer before the touch-input device processes the input. The low-latency touch-input device then processes the input to generate a digital representation of the writing and renders the digital representation of the writing on the touchscreen display to replace the writing displayed on the physical layer.

Abstract: This document describes various techniques for implementing a variable-depth stereoscopic display. A first distance at which a viewer is disposed relative to a stereoscopic display is received. Once received, a second distance by which to change a front focal distance of a lens structure of the stereoscopic display is determined based on the first distance. The front focal distance of the lens structure is then caused to change by the second distance effective to display a stereoscopic image at the first distance.
