A touch field is created around a touchscreen display, the field is in front of a touch surface of the display and the field maps to locations on the display. An operator of a terminal during a transaction is presented with transaction interface screens that are visually rendered on the display. The operator makes interface options selections, performs screen navigation, and provides date entry field inputs by placing the operator's hand within the field without touching the touch surface of the display and making hand poses, hand movements, and/or hand gestures. The poses, movements, and/or gestures are translated into touch actions and touch inputs recognized by the transaction interface and processed as operator-provided input during the transaction.

A mobile device includes a housing, a network interface to communicate with an external network, a user interface comprising a panel with a display panel to display a menu image and a touch panel to receive a touch input, the panel including a first portion and a second portion with a transparent condition and being within the first portion, a sensing unit including two front cameras disposed in the second portion of the panel, and a control unit to control the sensing unit in a photographing mode and a sensing mode to perform a function of the mobile device.

There is provided a user equipment. The user equipment has a body. The user equipment includes at least one gesture sensor configured to, when activated, detect movement, outside the body and in at least one direction from the body, of a user interacting with the user equipment. The user equipment includes a visual user interface configured to provide visual feedback of activation of the gesture sensor. The visual feedback indicates in which at least one direction from the body the detection of movement using the gesture sensor has been activated.

A biometric authentication system including: a translucent protective plate having an authentication region on a front face of the protective plate, and a reverse side forming the second face of the plate, essentially in parallel to the front face; a light emitting source to illuminate an object pressed against or being in touch with the authentication region; a sensor arranged at the reverse side or in a distance from the reverse side; an optical path from the authentication region to the sensor; an optical filter within the optical path;
whereat the optical filter is a layered near infrared (NIR) filter including: at least one of an inner ZnO.sub.x and/or inner TiO.sub.x layer at a substrate side; followed by a multitude of silver layers, each silver layer being separated from each neighboring silver layer by at least one of a further ZnO.sub.x and/or a further TiO.sub.x layer; at least one of an outer ZnO.sub.x layer, an outer TiO.sub.x layer, and/or a blocking layer deposited on the outermost silver layer.

An example touch/pen (T/P) sensor device includes a T/P sensor to generate position information based on user interaction with a sensor surface of the T/P sensor, and a color sensor to sense a color hue of a writing tip of a pencil to be used to interact with the sensor surface of the T/P sensor to generate a digital image. The T/P sensor device also includes a processor to record metadata with the digital image to indicate the sensed color hue.

A display device includes a display panel, a cover glass disposed on the display panel, and a biometric sensor device disposed below the display panel. The biometric sensor device includes a printed circuit board, a biometric sensor disposed on the printed circuit board, and a housing disposed on the printed circuit board and in which an opening is formed. The biometric sensor is disposed in the opening of the housing and is attached to a surface of the display panel through the housing.

According to the invention, the photosensitive module is disposed below the display unit and is located on or near the optical axis for imaging of physiological feature information of the user, so that compared with a structure having a camera separately disposed on the peripheral edge of a display, the apparatus of the invention can timely capture the physiological feature information (such as eye motion information) of the user, shorten the detection response time and improve user experience. In addition, the photosensitive module is disposed below the display unit, and the display unit with infrared pixels emits infrared light, so that compared with the structure having the camera separately disposed outside the display, the overall thickness of mobile devices can be effectively decreased, wearable devices or mobile devices are lighter and thinner, and the apparatus is more suitable for flexible wearable devices or mobile devices and can meet market requirements.

A light detection circuit, an electronic device, and an optical recognition method are provided. The light detection circuit includes a charge storage sub-circuit (10), a photoelectric conversion sub-circuit (30), a signal collection sub-circuit (40), and a potential pull-up sub-circuit (50). When a potential of a reading node (A) is decreased by a preset value, the potential pull-up sub-circuit (50) changes the potential of the reading node (A) to an initial potential. A photoelectric diode may continuously generate a light current under the action of light, so that the potential of the reading node (A) is decreased again. Even when the intensity of ambient light is high, a touch can be accurately recognized in an optical touch recognition circuit, and ridge lines and valley lines can be accurately recognized in an optical fingerprint recognition circuit.

A projector includes an imaging section for generating imaging data obtained by taking an image of first light emitted by a first pointing member, second light emitted by a second pointing member, and a target range, and a position detection section for detecting a first position and a second position with respect to the target range based on the imaging data so as to be distinguished from each other, and the imaging section includes a sensor for outputting detection values of first colored light, second colored light, and third colored light to detect first infrared light and light with a first wavelength included in the first light, and second infrared light and light with a second wavelength different from the first wavelength included in the second light with the sensor.
