Abstract
According to the invention, a system for converting sound to electrical signals is disclosed. The system may include a gaze tracking device and a microphone. The gaze tracking device may determine a gaze direction of a user. The microphone may be more sensitive in a selected direction than at least one other direction and alter the selected direction based at least in part on the gaze direction determined by the gaze tracking device.
Claims7
A system for converting sounds to electrical signals, wherein the system comprises:
- a gaze tracking device, wherein the gaze tracking device determines a gaze direction of a user;
- multiple stationary microphones comprising a first stationary microphone and a second stationary microphone;
- a camera;
- a display device reproducing a scene captured by the camera, wherein:
- the gaze tracking device determining the gaze direction of the user comprises determining a gaze point of the user on the display device;
- wherein the first stationary microphone is more relatively directed towards the gaze direction than the second stationary microphone;
- and
- processing outputs from the multiple stationary microphones for delivering directional sensitivity, wherein said processing comprises adding a delay to a signal received from the first stationary microphone to create a delayed signal, and then summing the delayed signal with a signal received from the second stationary microphone.
A method for converting sounds to electrical signals, wherein the method comprises:
- reproducing a scene captured by a camera on a display device;
- determining the gaze direction of the user with a gaze tracking device, wherein determining the gaze direction comprises determining a gaze point of the user on the display device;
- processing outputs from the multiple stationary microphones for delivering directional sensitivity, said multiple stationary microphones comprising a first stationary microphone and a second stationary microphone;
- and
- wherein said processing outputs from the multiple stationary microphones for delivering directional sensitivity comprises adding a delay to a signal received from the first stationary microphone to create a delayed signal, and then summing the delayed signal with a signal received from the second stationary microphone, wherein the first stationary microphone is more relatively directed towards the gaze direction than the second stationary microphone.
A non-transitory machine readable medium having instructions stored thereon, wherein instructions are executable by a processor to at least:
- reproduce a scene captured by a camera on a display device;
- receive, from a gaze tracking device, data representing a gaze direction of a user;
- determining the gaze direction of the user from the data, wherein determining the gaze direction comprises determining a gaze point of the user on the display device;
- processing outputs from the multiple stationary microphones for delivering directional sensitivity, said multiple stationary microphones comprising a first stationary microphone and a second stationary microphone, and
- wherein said processing outputs from the multiple stationary microphones for delivering directional sensitivity comprises adding a delay to a signal received from the first stationary microphone to create a delayed signal, and then summing the delayed signal with a signal received from the second stationary microphone, wherein the first stationary microphone is more relatively directed towards the gaze direction than the second stationary microphone.
