  • Patent number: 11175774
    Abstract: A method for determining a time of contact of a capacitive sensor includes continuously measuring a capacitance value of the capacitive sensor and processing the measured capacitance value into a digital sensor signal. The sensor signal is filtered to output a filter signal. Initial dynamics of the filter signal are identified upon the filter signal exceeding a first set filter threshold value. A time at which the filter signal falls below a second set filter threshold value is determined as being a potential time of contact of the capacitive sensor. An actual time of contact of the capacitive sensor is determined when the sensor signal relative to an offset of the sensor signal exceeds a sensor signal threshold value. The offset of the sensor signal is a value of the sensor signal prior to the contact of the capacitive sensor.

  • Patent number: 11106276
    Abstract: A virtual reality (VR) headset adjusts the phase of light of a virtual scene received from a display element using a spatial light modulator (SLM) to accommodate changes in vergence for a user viewing objects in the virtual scene. The VR headset receives virtual scene data that includes depth information for components of the virtual scene and the SLM adjusts a wavefront of the light of the virtual scene by generating a phase function that adjusts the light of the virtual scene with phase delays based the depth values. Individual phase delays shift components of the virtual scene based on the depth values to a target focal plane to accommodate a user at a vergence depth for a frame of the virtual scene. Further, the SLM can provide optical defocus by shifting components of the virtual scene with the phase delays for depth of field blur.
