  • Patent number: 11847261
    Abstract: A computer device is provided that includes a display device, and a sensor system configured to be mounted adjacent to a user's head and to measure an electrical potential near one or more electrodes of the sensor system. The computer device further includes a processor configured to present a periodic motion-based visual stimulus having a changing motion that is frequency-modulated for a target frequency or code-modulated for a target code, detect changes in the electrical potential via the one or more electrodes, identify a corresponding visual evoked potential feature in the detected changes in electrical potential that corresponds to the periodic motion-based visual stimulus, and recognize a user input to the computing device based on identifying the corresponding visual evoked potential feature.

  • Patent number: 10129684
    Abstract: Systems and methods of providing an audio signal are disclosed herein. In one embodiment, a method of delivering an audio signal from a device toward a user's ear includes, for example, transmitting a filtered audio signal from a transducer positioned at a location on the device that is longitudinally spaced apart from an entrance of an auditory canal of the user's ear when the device is worn on the user's head.

  • Publication number: 20160345095
    Abstract: Systems and methods of providing an audio signal are disclosed herein. In one embodiment, a method of producing an audio signal includes applying, for example, a head related transfer function (HRTF) and a transducer position compensation filter to an input audio signal to generate an enhanced audio signal configured to be transmitted toward an entrance of the user's ear from a transducer carried by a headset and spaced apart from the entrance to a user's ear.
