First Claim
Patent Images
1. A method of signal processing, said method comprising:
- producing a command in response to a representation of a hand gesture of a user, wherein the hand gesture indicates (i) a change to a sound field near the user and (ii) a direction of where to direct the sound field, wherein the sound field comprises a beam;
producing a filter configuration for a spatially directive filter in response to said command based on a current filter configuration;
applying the spatially directive filter to a multichannel signal; and
driving an array of directionally controllable transducers with the multichannel signal to change the sound field that includes the beam.

29. An apparatus for signal processing, said apparatus comprising:
-
a gesture interpreter configured to produce a command in response to a representation of a hand gesture of a user, wherein the hand gesture indicates (i) a change to a sound field near the user and (ii) a direction of where to direct the sound field, wherein the sound field comprises a beam; a command interpreter configured to produce a filter configuration for a spatially directive filter in response to said command based on a current filter configuration; a synthesizer configured to apply the spatially directive filter to a multichannel signal; and an audio output stage configured to drive an array of directionally controllable transducers with the multichannel signal to change the sound field that includes the beam. - View Dependent Claims (30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 46, 49, 50, 51, 52, 53, 54)

43. A non-transitory computer-readable medium having tangible features that cause a machine reading the features to:
-
produce a command in response to a representation of a hand gesture of a user, wherein the hand gesture indicates (i) a change to a sound field near the user and (ii) a direction of where to direct the sound field, wherein the sound field comprises a beam; produce a filter configuration for a spatially directive filter in response to said command based on a current filter configuration; apply the spatially directive filter to a multichannel signal; and drive an array of directionally controllable transducers with the multichannel signal to change the sound field that includes the beam. - View Dependent Claims (47)
