Each projector specifies coordinates of a position which is indicated by an indicator, and outputs coordinate information representing the coordinates which are specified, and identification information identifying a display position of the image. An information processing device includes a conversion unit converting the coordinate information into coordinate information representing coordinates in a coordinate system of the information processing device on the basis of the identification information.

A display device has a pixel array including a plurality of pixels arranged in a matrix and a backlight provided to face a substrate over which the pixel array is formed, and display element portions photosensor portions are formed in the pixels. In the display device, in one frame period for displaying a black image which is interposed between two successive periods forming an image or a backlighting shutoff period in one frame period in which the display element portion holds an image, an accumulation operation of the photosensor portion is performed, the pixels are successively selected for each row, and a signal corresponding to the potential of a signal charge accumulation portion of the photosensor portion is output.

Control apparatus includes an optical subsystem, which is configured to direct first light toward a scene that includes a hand of a user in proximity to a wall of a room and to receive the first light that is reflected from the scene, and to direct second light toward the wall so as to project an image of a control device onto the wall. A processor is configured to control the optical subsystem so as to generate, responsively to the received first light, a depth map of the scene, to process the depth map so as to detect a proximity of the hand to the wall in a location of the projected image, and to control electrical equipment in the room responsively to the proximity.

In one aspect, an illumination device with integrated touch sensor capability includes a light guide having a metalized light-turning feature and an electrode system for sensing changes to the capacitance between electrodes in the electrode system induced by the proximity of an electrically conductive body, such as a human finger. The metalized light-turning features may be electrically connected to and/or part of the electrode system.

An input sensor, an electronic device comprising such, and a method of manufacturing the same are described. The input sensor may be implemented as part of a mechanical key input. The input sensor includes a substrate having a first substrate portion with a signal pattern unit patterned therein, the signal pattern unit configured to generate a signal according to a touch or proximity of an object, and a second substrate portion having an integrated circuit united disposed thereon, the integrated circuit being electrically connected to the surface pattern unit, and a key support having a seating portion configured to support the substrate. The input sensor, electronic device, and the manufacturing method can be modified without limit.

This disclosure provides methods and systems for mitigating pathogen transmission via a touch surface of a touch input device. Mitigation is accomplished through selective touch surface sterilization and through touchscreen user interface reorganization. The touch surface includes a pixel array for illuminating selected portions of the touch surface with ultraviolet light of a sterilization wavelength based upon the received touch inputs. The selective illumination may occur while receiving a touch input or after an accumulation of touch inputs have been received. The user interface may also be reorganized based on received touch inputs in order to locate user interface icons to lesser touched locations of the touch surface.

A wearable device includes: a touch screen; an acceleration sensor configured to generate an acceleration signal; an optical sensor using a light source and configured to generate a touch interrupt signal; and a control unit configured to detect a wearing state of the wearable device, the wearing state of the wearable device including a not-wearing state for the wearable device, a wrist wearing state, and a hand gripping state on the basis of the acceleration signal and the touch interrupt signal, and to execute a function corresponding to the wearing state of the wearable device.
