Abstract: This disclosure relates to an interactive display, having a front surface including a viewing area, and providing an input/output interface for a user of an electronic device. A planar light guide (PLG) disposed substantially parallel to the front surface, has a periphery at least coextensive with the viewing area. A light-emitting source (LES), disposed outside the periphery of the PLG, is optically coupled with a PLG input. The PLG outputs reflected light, in a direction substantially orthogonal to the front surface, by reflecting light received from the LES. A light collecting device (LCD) collects scattered light that results from interaction of the reflected light with a user-controlled object. The LCD redirects the collected scattered light toward one or more light sensors. A processor recognizes, from outputs of the light sensors, an instance of a user gesture, and controls the interactive display and/or electronic device, responsive to the user gesture.

Abstract: A display engine assembly comprises a first imager and a second imager to generate a left image and a right image, respectively, in a head-mounted display device. The left and right images are left and right components, respectively, of a single stereoscopic image. The display engine further comprises an optical waveguide optically coupled to the first imager and the second imager. The optical waveguide is part of a first optical path to convey the left image to a left eye of a user of the head-mounted display device and is also part of a second optical path to convey the right image to a right eye of the user of the head-mounted display device.

Abstract: An environmental sensing device includes an interferometric modulator which permanently actuates, in a visually-detectable manner, in response to being exposed to a predetermined environmental threshold or condition. The device can include a reactive layer, coating, or proof mass disposed on a movable member of the interferometric modulator. The reactive layer, coating, or proof mass can expand, contract, bend, or otherwise move when exposed to a predefined chemical, level of humidity, temperature threshold, type of radiation, and/or level of mechanical shock, causing the interferometric modulator to collapse and permanently indicate such exposure.
