A floating touch display device and a floating touch method are provided. The floating touch display device includes a display layer, a protective cover, light emitting units, and light receiving units; the protective cover includes a first region and a second region surrounding the first region; the display layer is disposed under the first region; the light emitting units and the light receiving units are sequentially arranged under the second region. Each of the light emitting units corresponds to one light receiving unit. The floating touch is realized, by a light emitting unit transmitting an optical signal toward a direction above the protective cover and a corresponding light receiving unit of the light emitting unit that receives the optical signal reflected by a touch object above the protective cover. Such a design can extend a touch range of the floating touch and improve user experience.

A touch sensing apparatus is disclosed, comprising a light transmissive panel that defines a touch surface, an opposite rear surface, and panel sides extending between the touch surface and rear surface. The panel sides define a perimeter of the light transmissive panel. The touch sensing apparatus comprises a plurality of light emitters and detectors arranged along the perimeter and adjacent the panel sides, a light guide arranged along the perimeter and having a first reflective surface comprising a diffusive light scattering element. The light emitters are arranged to emit a respective beam of light onto the diffusive light scattering element so as to generate propagating light that diffusively propagates above the touch surface, wherein the light detectors are arranged to receive detection light generated as said propagating light impinges on the diffusive light scattering element, and wherein the diffusive light scattering element is arranged at least partly outside the panel sides and extending at least partly above the touch surface.

A gaming device, and related devices, methods, and systems, may include a touch input device to detect touch inputs performed by a user, and a gesture input device to detect gesture inputs performed by the user. The gaming device may further includes a processor circuit and a memory coupled to the processor circuit. The memory may include machine-readable instructions that, when executed by the processor circuit, cause the processor circuit to: receive a first gesture input value from the gesture input device, predict, based on the first gesture input value, a predicted touch input value corresponding to a predicted touch input that is predicted to be performed by the user, and modify a user interface element of the gaming device based on the first gesture input value and the predicted touch input value.

An electronic device using a novel optical module is provided. The optical module includes a first light-emitting element, an optical conversion element, and a first light-receiving element. The first light-emitting element includes a plurality of fluorescent substances and a light-emitting diode. The optical conversion element includes a first optical filter. The light-emitting diode emits first light, and the fluorescent substances can emit second light by being excited by the first light.

A display panel and a manufacturing method thereof are disclosed. The display panel includes: a base substrate; a first sub-pixel disposed on the base substrate and including a first light-emitting device configured to emit visible light for display operation; a second a light-emitting device overlapped with the first light-emitting device in a direction perpendicular to the base substrate and configured to emit infrared light; and a first photosensitive device disposed on the base substrate and configured to sense light obtained after the infrared light is reflected.

A system for interacting with a screen without touching it, comprising a source of radiating energy directed into a predefined area, at least one directionally sensitive sensor that detects the radiation when it's reflected off of an object within the predefined area, and a processor that calculates position and motion information of the object and generates therefrom image information, which it sends to a screen where it is displayed.

Provided is an image display method for performing drawing in a display region overlapping at least with a part of an external scene in a state in which the external scene is visible. The image display method images a region including the display region, and extracts an operating object from a captured image in which this region is imaged, as a region of a color of the operating object. In accordance with a size of the region of the color thus extracted, a drawing mode of the operating object is changed, and image display in the display region is controlled in accordance with the changed drawing mode. As the control of the image display, for example, performing drawing, and moving or replicating a drawn image is assumed.

An electronic device such as a head mounted device may have an inner display that displays an image for a user through lenses. Head-mounted support structures may be used to support the display and lenses. One or more external displays may be publically viewable while the head-mounted device is being worn. The head-mounted support structures may have a front face on which an external display is mounted. One or more finger sensors that are configured to detect touch input, force input, and/or other input from an external object such as a user's finger may be included in the head-mounted device. A finger sensor may have an elongated shape that runs along a peripheral edge of an external display on the front face. Finger sensors may also be located on other portions of the support structures.
