  • Patent number: 10996795
    Abstract: An optical touch-sensitive device includes a touch-sensitive surface over which touch events are detectable. The device also includes surface features on the surface that reduce touch object friction relative to an absence of surface features. Emitter and detectors are arranged along a periphery of the touch-sensitive surface. The emitters can produce optical beams that travel across the touch-sensitive surface to the detectors. Touches on the touch-sensitive surface disturb the optical beams and the touch-sensitive device determines touch events based on the disturbed optical beams. The surface features may also be arranged to reduce glare by diffusing light. In some embodiments, an anti-reflective layer is on top of the touch-sensitive surface and the surface features.

  • Patent number: 10969590
    Abstract: A near-eye display has a light-guide optical element (LOE) with two major parallel external surfaces. An image projector introduces image illumination into the LOE so as to propagate by internal reflection. The image projector includes one or more light-generating laser diode operated by a controller. A coupling-out arrangement includes a set of mutually-parallel, partially-reflective surfaces associated with the LOE at an oblique angle to the major external surfaces for coupling the illumination out of the LOE towards the eye of the observer. The light-generating laser diode has a characteristic variation of coherence length of generated light as a function of diode actuation power. The controller actuates the laser diode at a level of diode actuation power that generates light with a coherence length that is less than twice a spacing between adjacent partially-reflective surfaces of the coupling-out arrangement.
