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.

Abstract: A light guide of the tapered-waveguide type includes an input slab for expanding a projected image between an input end and an output end; and a tapered output slab arranged to receive rays from the said output end of the input slab, and to emit them at a point on its face that corresponds to the angle at which the ray is received. The taper is calculated so that all rays injected into the input end undergo the same number of reflections before leaving the output face. The thickness of the input slab light guide is greater in the transverse direction away from the center line, so that light travelling at the critical angle from the input face of the slab waveguide towards the output waveguide bounces the same number of times in the input slab, regardless of its fan-out angle, in order to further reduce image distortion.

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.
