Abstract:
A method includes obtaining a partial frame by sampling parts of a frame from a touch panel which comprises an array of sensor areas (step S1). The method also includes generating, based on the partial frame, a new frame which comprises estimates of the un-sampled parts (step S2). The method also includes determining whether at least one touch event is present in the new frame (step S3), and upon a positive determination, for each touch event, determining a location of the touch event in the new frame and obtaining a sub-frame by sampling a region of a subsequent frame from the touch panel frame at and around the location (step S4). The method also includes outputting touch information based on one or more sub-frames (step S7).
Abstract:
Always-on or nearly always-on sensing of human touch at a device is provided. The sensing is split into a low-power detection stage and a full-power analysis stage, where the detection stage is implemented continually or nearly continually and causes system circuitry to perform analysis of the human touch after the low-power detection stage has confirmed the human touch. The sensing permits avoiding the reliance on physical actuation of a trigger prior to analysis of human touch.
Abstract:
A method and apparatus that resolve near touch ambiguities in a touch screen includes detecting a touch screen touch event and detecting a vibro-acoustic event. These events generate signals received respectively by two different sensors and/or processes. When the two events occur within a pre-defined window of time, they may be considered to be part of the same touch event and may signify a true touch.
Abstract:
An optical touch-sensitive device detects touch events caused by instruments (e.g., pens, styluses) and distinguishes these events from touch events caused by fingers. In some embodiments, different instruments can also be distinguished. The optical touch-sensitive device includes multiple emitters and detectors. Each emitter produces optical beams which are received by the detectors. The optical beams preferably are multiplexed in a manner so that many optical beams can be received by a detector simultaneously. Touch events disturb the optical beams, for example due to frustrated total internal reflection. Information indicating which optical beams have been disturbed is analyzed to detect one or more touch events. The analysis also distinguishes instrument touch events from finger touch events.
Abstract:
A mobile terminal and controlling method thereof are disclosed, by which a touch sensitivity of a display unit can be improved. The present invention includes a display unit, a touch sensor configured to detect a touch input applied to the display unit by periodically waking up while the display unit is turned off, and a controller, if a preset user input is received, controlling a wakeup period of the touch sensor distributed in at least one partial region of the display unit to be decreased.

Abstract:
Systems and methods for context-based touch-sensing and processing are disclosed. The energy-efficiency of a touch sensitive device may be improved by dynamically adjusting the function of the touch sensitive surface in real-time based on contextual information such as expected QoS, expected user input in defined regions-of-interest of the touch sensitive surface, and usage modalities of the touch sensitive device.
