Various implementations disclosed herein include devices, systems, and methods that obtain information from a first electronic device (e.g., to improve interactions for a CGR environment). In some implementations at a second electronic device having a processor, event camera data is obtained corresponding to modulated light (e.g., light including an information signal in its modulation) emitted by an optical source on the first electronic device and received at an event camera. The second electronic device is able to identify information from the first electronic device based on detecting a modulation pattern of the modulated light based on the event camera data. In some implementations, second electronic device is the same electronic device that has the event camera (e.g., laptop) or a different electronic device that receives the event data (e.g., a server receiving the event data from a laptop computer).

The present disclosure relates to an information processing apparatus, an information processing method, and a program capable of, when accepting hand-based operation inputs from a plurality of users, performing appropriate pairing of left and right hands for each user.

An image of an operation surface from above is acquired, the operation surface being configured to accept a hand-based operation input from users, left and right hands of the users and arms corresponding to the respective hands are detected from the image, a base position of one of the arms is set as a benchmark position, a base position of the arm that is closest adjacent along a periphery of the operation surface is set as a reference position when the one of the arms is a left hand, and pairing of the hand of the arm at the benchmark position and the hand of the arm at the reference position is performed. The present disclosure can be applied to an information processing system.

A pointer position detection method performed by a sensor controller connected to a sensor pattern includes: detecting a pen signal transmitted via a pen electrode provided at a distal end of an active pen, detecting a position of the active pen based on a level of the pen signal detected; detecting one or more candidate touch positions of a passive pointer that does not transmit a signal by detecting one or more changes of one or more capacitances of the sensor pattern, and outputting, as the position of the passive pointer, the one or more candidate touch positions remaining after excluding the position of the active pen from the one or more candidate touch positions.

A method of fabricating a thin-film transistor (TFT) photodetector includes forming diffusion layers on a glass substrate or a transparent flexible substrate, wherein the diffusion layers include a P-type diffusion layer of P-type polycrystalline or amorphous silicon, for use as an active layer and P+-type diffusion layers of amorphous or polycrystalline silicon at both sides of the P-type diffusion layer, forming an insulating oxide layer on the formed diffusion layers, forming an N-type diffusion layer of polycrystalline or amorphous silicon on the insulating oxide film, forming a gate to be used as a light receiving part by photo-patterning the N-type diffusion layer, etching the generated insulating oxide layer except for only a necessary part in a photoresist (PR) patterning process, removing a remaining area of the P+-type diffusion layer except for areas to be used as a source and a drain by etching, and generating electrodes by depositing a metal in etched parts of the insulating oxide film in the source and the drain.

An electronic device and a fingerprint image correction method are provided. The electronic device includes an optical fingerprint sensor and a processor. The optical fingerprint sensor is used to obtain a fingerprint image. The processor is coupled to the optical fingerprint sensor. The processor judges multiple analog-to-digital converter values of multiple pixels of the fingerprint image according to a numerical mask to generate a comparison image. The processor compares the comparison image with a sample image to obtain a pressure level classification corresponding to the fingerprint image.

A touch panel and a touch panel operation method are disposed. The touch panel includes an active region and a non-active region in an operating state, and the touch panel includes a plurality of sensing electrodes and a controller. The plurality of sensing electrodes are disposed in the active region and the non-active region. The controller receives an active touch signal from the plurality of sensing electrodes located in the active region and a non-active touch signal from the plurality of the sensing electrodes located in the non-active region. The controller manages the active touch signal and the non-active touch signal, so that only the active touch signal is subjected to a subsequent process.

A transparent display can allow viewing of real world content through the display, while rendering virtual content to the display. A display may take the form of a touch-sensitive display, allowing user input directly through physical interaction with the display. A display may include a pair of major outer-most faces and a pair of inner faces, one of the inner faces angled to reflect light from a projector, outward via one of the major outer-most faces. The gap may advantageously be formed via a pocket extending inwardly from an edge of an optical substrate that comprises the display.
