An interactive projection system including a projector and a touch interactive light source device is provided. The projector includes a projection optical engine, a camera module, and a control module. The touch interactive light source device includes at least one infrared light source module and a wireless signal transmission module. The control module is electrically connected to the projection optical engine and the camera module, and controls the touch interactive light source device through the wireless signal transmission module, so that the touch interactive light source device is placed in a recommended installation position and the interactive projection system is in an interactive mode. An operation method of the interactive projection system is also provided.

An information processing apparatus includes a processor configured to: detect a closest portion being a portion having a shortest distance from an operation surface in a perpendicular direction of the operation surface among portions of an object in a spatial region facing the operation surface; determine a position on the operation surface corresponding to a position of the closest portion as an instruction input position by a non-contact operation of a user; and, in a case where a distance between a first position of the closest portion, which is detected at a first time point, and a second position of the closest portion, which is detected at a second time point after a minute time has elapsed from the first time point, in a plane direction parallel to the operation surface is equal to or longer than a threshold distance, invalidate an instruction input on a position on the operation surface corresponding to the second position or output a warning to the user.

Provided is a character input method and apparatus for automatically switching an input mode in a terminal having a touch screen. If a press event occurs in one of key regions displayed in the touch screen, it is determined whether a drag event occurs prior to occurrence of a release event. According to whether the drag event occurs, one of a separate input mode for inputting one of characters of a corresponding character group and a text input mode for inputting a word including one of the characters of the character group is executed. Thus, a user can easily input a character by rapidly selecting a desired input mode.

A component for a vehicle interior may comprise a housing; a cover structure comprising a cover surface; and a user interface at the cover surface comprising a light display. The light display may comprise a light guide comprising a projection. The cover structure may comprise a cover base and a cover layer. The cover layer may be molded on the cover base. The cover base may comprise the light guide. The cover layer may comprise an aperture. The projection may extend into the aperture. The cover base may comprise an aperture, recess, notch and/or indentation. The cover layer may comprise a generally opaque material preventing visibility of a recess in the cover base. The cover base may comprise a different color and/or softness than the cover layer. The cover structure may comprise apertures and/or recesses for the light guide.

A touch display device includes several LED units and several switches. Each LED unit includes a LED and a photo sensor. The switches are electrically coupled to the LED units. During a conductive period of a conductive one of the switches, the LEDs and the photo sensor coupled to the conductive one are enabled non-simultaneously.

A display device includes a substrate; a barrier layer above a first surface of the substrate; a protective film below a second surface of the substrate opposite the first surface; an adhesive member between the substrate and the protective film; and an optical sensor below a second surface of the protective film opposite a first surface of the protective film that faces the second surface of the substrate.

An image display apparatus includes a display section that displays an image on a display surface, an output section that outputs light, a changer that changes the angle of the light outputted from the output section with respect to the display surface, a position detector that detects a reflected position where the light outputted by the output section is reflected, and a change controller that controls the changer based on the result of the detection performed by the position detector.

A display device capable of reducing a non-display area includes a substrate hole surrounded by light emitting elements, and a moisture penetration preventing layer disposed between an inner dam surrounded by the light emitting elements and the substrate hole. Accordingly, it is possible to prevent damage to light emitting stacks caused by external moisture or oxygen. Since the substrate hole is disposed within an active area, a reduction in non-display area is achieved.
