  • Patent number: 11751462
    Abstract: A display may have both a full pixel density region and a pixel removal region with a plurality of high-transmittance areas that overlap an optical sensor. Each high-transmittance area may be devoid of thin-film transistors and other display components. To improve transmission while maintaining satisfactory touch sensing performance, one or more segments of the touch sensor metal in the pixel removal region may have a reduced width relative to the touch sensor metal in the full pixel density region and/or one or more segments of the touch sensor metal in the pixel removal region may be omitted relative to the touch sensor metal in the full pixel density region. To mitigate a different appearance between the pixel removal region and the full pixel density region at off-axis viewing angles, the position of the touch sensor metal in the pixel removal region may be tuned.

  • Patent number: 11726557
    Abstract: Program actions may be initiated after detection of a predefined gesture by a user with a real-world object. Users may interact with their physical environment in an augmented reality by detecting interactions with real objects using a combination of location and motion detection, material identification using wearable sensors, or both. Based on detected sensor data from user interaction with a real-world object, a predefined gesture may be identified and a program action associated with that target interaction for the real-world object may be executed. In some cases, the user experience may be enhanced by providing haptic feedback in response to tactile gestures and resulting events.
