A non-contact-type information processing device includes a display mechanism having a display surface which displays an image, an aerial-image forming mechanism which forms an image as an aerial image by projecting the image displayed on display surface to a space, and an annularly formed antenna for communication. The antenna is disposed on an outer peripheral side of an aerial-image display region so as to surround the aerial-image display region, which is the region in which an aerial image is displayed.

An electronic device is provided. The electronic device includes a sensor unit comprising one or more sensors, a display comprising a touch sensor, and at least one processor for controlling the electronic device, wherein the processor may detect a touch input through the touch sensor, when a touch input is detected, determine whether the touch input is valid on the basis of state information generated through the one or more sensors, when it is determined that the touch input is valid, determine a target level of responsiveness for the touch input from among a plurality of levels on the basis of at least one of the state information and application information about an application being executed by the electronic device, and control the electronic device on the basis of the target level.

Provided is an information processing apparatus capable of further improving operability. A virtual touch panel surface that does not actually exist is set in a space in front of a display surface of a display. Then, a touch operation on the virtual touch panel surface performed by a user is detected on the basis of position information of a specific site of a body used by the user for the touch operation on the virtual touch panel surface, and processing corresponding to the detected touch operation is executed. Here, in the setting of the virtual touch panel surface, a curvature radius of a movement trajectory of the specific site when the user has moved the specific site in a predetermined direction is calculated on the basis of the position information of the specific site, and a flat surface is set as the virtual touch panel surface in a case where it is determined that the calculated curvature radius is larger than a predetermined threshold, and a curved surface whose central portion is recessed to a side of the display is set as the virtual touch panel surface in a case where it is determined that the curvature radius calculated by a calculation unit is equal to or smaller than the predetermined threshold.

A method for determining for determining response for a touch display panel begins by receiving an analog input signal from a data drive input circuit that is operable to generate an analog input signal based on a digital input. The method continues by generating a reference signal voltage from the analog input signal, generating a data signal voltage from the analog input signal and using a difference detection circuit, outputting an analog output voltage. The method then continues by generating an error correction current based on the analog output voltage, where the error correction current adjusts the data signal voltage in order to keep inputs to the difference detection circuit substantially equal. Finally, the method finishes by generating a current representative of a light intensity for light received by a sensor cell associated with the touch display panel, converting the analog output signal into a digital representation of the current and producing information representative of light intensity.

An interactive display apparatus includes a projector, a 3D sensing device, and a control unit. The projector projects, from an origin, an image defined by image data onto a projection surface. The 3D sensing device senses, in a monitored space between the origin and the projection surface, and generates 3D sensing data representative of results of the 3D sensing. The control unit is configured to compute reference surface data representative of a virtual reference surface corresponding to the projection surface, control the sensing device to generate secondary 3D sensing data, retrieve a measurement offset value, determine from the secondary 3D sensing data and the reference surface data, a measured height representative of a sum of the measurement offset value and a distance between the object and the projection surface, and generate a trigger signal.

An electronic device may have a touch sensitive display that is insensitive to the presence of moisture. An array of pixels in the display may be used to display images. A display cover layer may overlap the array of pixels. A light source may illuminate an external object such as a finger of a user when the object contacts a surface of the display cover layer. This creates scattered light that may be detected by an array of light sensors. The light source may supply light to an edge of the display cover layer at an angle that ensures total internal reflection within the display cover layer is sustained across the display cover layer even when the display cover layer is immersed in water or otherwise exposed to moisture.
