The present disclosure provides a touch device. The touch device includes a frame, a substrate, an infrared emitting unit, and an infrared receiving unit. The infrared emitting unit and the infrared receiving unit are disposed on the frame and located above the substrate. The touch device also includes: a connecting block which is connected at an edge region on a lower surface of the substrate, and an adjusting member which connects the connecting block and the frame and adjusts a lateral tensile force applied by the adjusting member to the substrate. The touch device of the present disclosure ensures the flatness of the substrate by the connecting block in cooperation with the adjusting member, avoiding the influence of the substrate on the infrared light, and has a simple structure and is convenient to assemble.

The present application discloses interaction method, system, and device for information. After recognizing a non-transparent shielding object or a second device, a first device with a light-sensing screen provided in the embodiments of the present application transmits shielded screen information to the second device for processing. One example is that the second device sends an operation instruction to the first device with a light-sensing screen according to a use scenario of a user, to change the screen information stored or/and displayed in the first device with a light-sensing screen. In this way, Interaction for information according to user requirements based on a photosensitive recognition technology between different devices may be implemented according to this application.

A method for imaging a fingerprint under a screen, including: acquiring a finger pressing area formed by a finger pressing on the screen; determining a first light source and a second light source of the screen based on the finger pressing area, wherein arrangement directions of the first light source and the second light source are not perpendicular to a long axis of the finger pressing area; acquiring a first fingerprint image after the first light source is turned on, and a second fingerprint image after the second light source is turned on; and splicing the first fingerprint image and the second fingerprint image to acquire a target fingerprint image.

An electronic device may have light-emitting devices. A light-emitting device may include light-emitting diodes, a display, or other components that emit visual output. One or more image transport layers may be included in the electronic device. An image transport layer may have an input surface that receives an image and an output surface to which the image transport layer transports the image for viewing by a user. The image transport layers may have areas with compound curvature and other shapes. Deformed image transport layer structures such as deformed fibers in a coherent fiber bundle may be configured to hide gaps in displays and other structures. Displays may include light detectors that serve as a two-dimensional touch sensor. The touch sensor may detect touch input on an output surface of an image transport layer. Image transport layer material may be incorporated into buttons, elongated housings, wearable devices, and other equipment.

The present disclosure relates to a vehicle table device that is extracted toward a driver or a passenger to place foods or books thereon for a simple meal or reading, and a method of controlling a virtual keyboard thereof. The method includes: determining a state of a table accommodated inside a housing by a controller; determining a position of a monitor by the controller when, in the determining of the state of the table, the table is determined to be extracted from the housing; and activating a virtual keyboard on the table by the controller when, in the determining of the position of the monitor, the monitor is determined to be located on a passenger seat side.
