    Abstract: Content-aware device selection is performed for modifying content elements in digital collaboration spaces. A content element, such as a text box or drawing space, is detected within a digital collaboration space based on input received from a first device of a first device type. A second device type to use to modify the content element is determined based on a content type of the content element. One or more devices of that second device type which are authenticated to access the digital collaboration space are identified. At least one of those authenticated devices are then prompted for input to use to modify the content element. The content element is then modified within the digital collaboration space based on the input received from at least one of those prompted devices.

  • Patent number: 11675470
    Abstract: Embodiments include a method and system for projected capacitive (PCAP) touchscreen construction with laser ablation. In glass/film/film (GFF) PCAP touchscreens, the films are coated with indium-tin-oxide (ITO), patterned by printing silver ink, and by ablating both the ITO and silver with a laser. A similar process occurs for a glass/glass (2GS) PCAP touchscreen. Embodiments include varying the pattern with which the laser ablates ITO on film within the touch area to improve touchscreen sensitivity. For example, by varying the width of patterns of floating ITO islands such that widths are less than or equal to a plan-view electrode gap between vertical and horizontal electrode pads and larger elsewhere, the touch sensitivity of the PCAP touchscreen may be improved and/or maximum touchscreen size may be increased.

  • Patent number: 10928782
    Abstract: System and techniques for a virtual detent bezel device are described herein, a configuration that specifies a detent pattern and an output pattern corresponding to the detent pattern may be received receiving by the virtual detent bezel device. A physical portion of the virtual detent bezel device may sense a rotational action of a user interacting with a physical portion of the virtual detent bezel device. The rotational action may be compared to a present rotational position to determine a rotational change. The rotational change may be thresholded against the detent pattern to determine that a detent is crossed. A haptic feedback device may be activated in response to determining that the detent is crossed. A portion of the output pattern that corresponds to the detent that is crossed may be output by the virtual detent bezel device.

  • Patent number: 10895932
    Abstract: Improved sensing can include modified sampling and/or processing to improve performance against noise due to environmental variations and interference. In some examples, improved interference rejection can be achieved by sampling a sensor multiple times during settled periods. In some examples, the excitation signal and sampling window can be dynamically adjusted to satisfy drift and/or interference specifications based on various operating conditions or the operating environment. In some examples, drift performance can be traded off to improve interference performance. In some examples, improved immunity to environmental variations can be achieved by equalizing sensor outputs in accordance with characterization of the sensing system. In some examples, improved performance can be achieved by sampling the sensor continuously and using an optimized window function to improve performance against noise.
