A display system includes visible light-emitting first devices and infrared light-emitting second devices, infrared light-detecting third devices, an optically reflecting first film between the third devices and the first and second devices, and an optically reflecting second film between the first film and third devices. The optically reflecting second film defines first openings aligned with the third devices in a one-to-one correspondence. The first devices emit a first wavelength in a visible wavelength range, and the second devices are configured to emit a second wavelength in an infrared wavelength range. The third devices are configured to detect the second wavelength. The first film has an average reflectance of greater than 60% for the visible wavelength range, and an average transmittance of greater than 50% for the infrared wavelength range. The second film has an average reflectance of greater than 60% for the visible and infrared wavelength ranges.

An interactive environment image may be displayed in a virtual environment space, and interaction with the interactive environment image may be detected within a three-dimensional space that corresponds to the virtual environment space. The interactive environment image may be a three-dimensional image, or it may be two-dimensional. An image is displayed to provide a visual representation of an interactive environment image including one or more virtual objects, which may be spatially positioned. User interaction with the visualized representation in the virtual environment space may be detected and, in response to user interaction, the interactive environment image may be changed.

The present invention provides an optically clear adhesive sheet having excellent environment resistance using a heat-curable polyurethane composition that has excellent flexibility and is capable of giving a thick film. The optically clear adhesive sheet of the present invention is formed of: a cured product of a heat-curable polyurethane composition, the heat-curable polyurethane composition containing a polyol component, a polyisocyanate component, and a tackifier, the polyol component having an olefin skeleton, the polyisocyanate component being a modified polyisocyanate that is obtained by reacting an acyclic aliphatic and/or alicyclic polyisocyanate containing an isocyanate group with an ether compound containing an ethylene oxide unit.

A touch panel and a touch panel operation method are disposed. The touch panel includes a flexible element and a controller. The flexible element includes a plurality of sensing electrodes. In a stacked state, a first portion of the flexible element overlaps a second portion of the flexible element. The controller for receiving an active touch signal from the plurality of sensing electrodes in the second portion of the flexible element and a non-active touch signal from the plurality of the sensing electrodes in the first portion of the flexible element. In the stacked state, the controller allows the active touch signal subject to a subsequent process.

A floating image generation device is disclosed, which includes a light source, an image generation module, and a floating image generation unit. The image generation module is disposed above the light source and includes a shading unit and an image generation unit. The shading unit is capable of changing light transmissivity state. The image generation unit is disposed above the shading unit. The floating image generation unit is disposed above the image generation unit. The light source emits a light passing through the shading unit, the image generation unit, and the floating image generation unit to generate a first floating image when the shading unit is in a first light transmissivity state. The light source emits a light passing through the shading unit, the image generation unit, and the floating image generation unit to generate a second floating image when the shading unit is in a second light transmissivity state.

The present disclosure provides a keyboard, including: a keyboard body; at least one physical key disposed on the keyboard body; at least one virtual key projection device connected to the keyboard body and configured to present, by means of projection, an image of at least one virtual key in a projection area outside the keyboard body; and a click detection device configured to detect whether a finger clicks on the projection area and determine on which virtual key the finger clicks in response to that the finger clicks on the projection area.
