  • Patent number: 12069453
    Abstract: A system to output a cross-talk cancelled spatial audio signal to two speakers, including a user tracking module to provide a location and orientation of a head of a user, and a time-domain dynamic crosstalk cancellation module to receive a spatial audio signal, the location and orientation of the head of the user from the user tracking module, a location for each of the two speakers, and generate the time-domain crosstalk cancelled spatial audio signal based thereon.
    Type: Grant
    Filed: February 25, 2020
    Date of Patent: August 20, 2024
    Assignee: Arizona Board of Regents on behalf of Arizona State University
    Inventors: Robert LiKamWa, Frank Wencheng Liu
  • Patent number: 11462128
    Abstract: A haptic feedback system to stimulate physical sensation of handling a fluid in virtual spaces. The system includes a physical vessel containing a solid object and mechanical means to move the solid object therein, a virtual reality module to track a position of the physical vessel and a corresponding virtual vessel, logic to simulate a fluid contained in the virtual vessel based on the tracked position of the virtual vessel, logic to calculate coordinates of a center of gravity for the simulated fluid based on the tracked position of the virtual vessel, logic to translate the calculated coordinates of the center of gravity for the simulated fluid into cylindrical coordinates to which to move the solid object in the physical vessel, and logic to send instructions to the mechanical means to move the solid object in the physical vessel based on the cylindrical coordinates to shift the weight of the physical vessel in accordance with the center of gravity of the simulated fluid in the virtual vessel.
