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.

Touch detection may include determining, based on data from an IMU on a first device that monitors movement of a touching object, a touch event, wherein the touch event indicates contact between the touching object and a surface, obtaining a depth image captured by a second device, comprising a touch image, determining a touch point of the object based on the touch image, and providing a response based on the touch point of the object and the touched surface.

An electronic device capable of detecting a difference in the way of touch is provided. An electronic device capable of detecting a difference in the way of touch with a small number of components is provided. An electronic device capable of executing various types of processes with simple operation is provided. The electronic device includes a control portion and a display portion. The display portion has a function of displaying an image on a screen and includes a detection portion. The detection portion has a function of detecting a touch operation and a function of imaging, at least twice, a detection object touching the screen. The control portion has a function of calculating a difference between the area of the detection object in first imaging and the area of the detection object in second imaging to execute a different process depending on whether the difference is larger or smaller than a reference.

A touch display system and a control method thereof are provided. The touch display system includes a touch display panel and a controller. The touch display panel includes a touch area and is configured to sense a touch operation of a user. The controller is coupled with the touch display panel and is configured to acquire a physical sign information of the user who is to operate the touch display panel, and adjust a touch range for the user to perform the touch operation in the touch area according to the physical sign information of the user.

The present disclosure provides a display panel and a driving method thereof. The display panel includes a substrate and a scan line, a light control device, and a display device on the substrate. The scan line is electrically connected to the light control device and the display panel, so that the light control device and the display device operate simultaneously.

An electronic device may have a touch sensitive display that is insensitive to the presence of moisture. The display may have a two-dimensional optical touch sensor that gathers touch input while the electronic device is immersed in water or otherwise exposed to moisture. The optical touch sensor may include light sources and light detectors. The light sources and the light sensors may be mounted on a common substrate with an array of image pixels. The image pixels may be formed by crystalline semiconductor light-emitting diode dies. Angular filters may be included over the light sources and/or the light detectors to improve discrimination between a user's finger and water droplets. The angular filters may be on-axis light blocking angular filters or off-axis light blocking angular filters.

A gesture-based text entry user interface for an Augmented Reality (AR) system is provided. The AR system detects a start text entry gesture made by a user of the AR system, generates a virtual keyboard user interface including a virtual keyboard having a plurality of virtual keys, and provides to the user the virtual keyboard user interface. The AR system detects a hold of an enter text gesture made by the user. While the user holds the enter text gesture, the AR system collects continuous motion gesture data of a continuous motion as the user makes the continuous motion through the virtual keys of the virtual keyboard. The AR system detects a release of the enter text gesture by the user and generates entered text data based on the continuous motion gesture data.

Input devices having a deformable membrane and methods of their use are disclosed. In one embodiment, an input device includes a body, a deformable membrane coupled to the body such that the body and the deformable membrane define an enclosure filled with a medium, and an internal sensor disposed within the enclosure, the internal sensor having a field of view configured to be directed through the medium and toward a bottom surface of the deformable membrane. The input device further includes a controller configured to receive an output signal from the internal sensor corresponding to a deformation in the deformable membrane, determine a gesture based on the output signal from the internal, and provide a gesture signal corresponding to the gesture.
