  • Patent number: 10983611
    Abstract: A touch sensitive surface has emitters and detectors arranged around at least a portion of a periphery of the touch sensitive surface. The emitters produce optical beams that are received by the detectors. Touch events disturb the beams propagating toward the detectors. Variations in the beams resulting from the touch events are captured and are used to determine the touch events. A stylus disturbs beams when in contact with the touch sensitive surface. The stylus includes a control that can change the stylus from a default state to an alternative state, where the stylus disturbs the beams differently in each state. A controller determines the state of the stylus based on the beams received by the detectors.

  • Patent number: 10979685
    Abstract: Methods and apparatus for focusing in virtual reality (VR) or augmented reality (AR) devices based on gaze tracking information are described. Embodiments of a VR/AR head-mounted display (HMD) may include a gaze tracking system for detecting position and movement of the user's eyes. For AR applications, gaze tracking information may be used to direct external cameras to focus in the direction of the user's gaze so that the cameras focus on objects at which the user is looking. For AR or VR applications, the gaze tracking information may be used to adjust the focus of the eye lenses so that the virtual content that the user is currently looking at on the display has the proper vergence to match the convergence of the user's eyes.
