  • Patent number: 9639210
    Abstract: A device implements a data processing method for an optical FTIR-based touch system. The touch system defines detection lines across a surface portion of a panel by propagating light inside the panel from a plurality of incoupling points to a plurality of outcoupling points, such that each location on the surface portion is illuminated by incident light rays. At least one light detector is coupled to the outcoupling points to generate an output signal. The device obtains signal values for the detection lines from the output signal and processes the signal values to at least partly compensate for variations in the apparent interaction among the subset of detection lines that interact with an object on the surface portion.

  • Patent number: 9626741
    Abstract: Systems and methods dynamically configure a display (104) of an electronic device (102) to a desired display resolution and/or a magnification factor without noticeable impact on the user viewing experience. According to certain aspects, the distance between a user (100) and the display is measured (1002), and the desired display resolution is determined (1006) based on the distance. If a user is exhibiting (1008, 1010) symptoms of presbyopia, a magnification factor may be determined (1012). A request indicating the desired display resolution and/or magnification factor is transmitted (1016) to a server that supplies images, such as pictures or videos. The image is received (1018) from the server and displayed (1020) on the display. A focus area distance and/or a pupil orientation of the user may also influence the desired display resolution. Bandwidth, processing, and power savings may result through the use of these systems and methods.
