  • Publication number: 20190096068
    Abstract: A method of camera pose and plane estimation may include detecting a marker within a 3-dimensional (3D) environment by detecting, using a Dynamic Vision Sensor (DVS), a first plurality of light sources arranged in a known shape and blinking at a first frequency, wherein the known shape corresponds to the marker, determining an orientation and an identity of the marker based upon detecting, using the DVS, a second plurality of light sources corresponding to the marker and blinking at a second frequency different from the first frequency. A camera pose for the DVS may be determined based upon the known shape, the orientation, and the identity of the marker using the processor.

  • Patent number: 10231673
    Abstract: A method for determining a stress level of a user based on a sympathovagal balance (SVB) value calculated based on a set of measurement data may include determining a heart-rate variability (HRV) characteristic as a ratio involving a number of autonomic nervous system (ANS) activity markers within a first portion of the set of measurement data and the number of ANS activity markers within a second portion of the set of measurement data, and then determining the stress level of the user based on the HRV characteristic. The first and second portions of the set of measurement data may be selected based on a user-specific baseline SVB value that divides a histogram representation of the set of measurement data into the first and second portions.
