Method and system for haptic beamforming and haptic effects in a handheld controller

1. A handheld controller comprising:

a housing including an interior space;

a first vibration source disposed in the housing, wherein the interior space between the first vibration source and the housing is filled with a mechanical structure;

a second vibration source disposed in the housing, wherein the interior space between the second vibration source and the housing is filled with the mechanical structure; and

a controller disposed in the housing, coupled to the first vibration source and the second vibration source, and configured to:

generate, via the first vibration source, first vibratory oscillations characterized by a first phase;

generate, via the second vibration source, second vibratory oscillations characterized by a second phase; and

vary at least one of the first phase or the second phase.

2. The handheld controller of claim 1 further comprising a third vibration source disposed in the housing, wherein the controller is configured to generate, via the third vibration source, third vibratory oscillations characterized by a third phase different from at least one of the first phase or the second phase.

3. The handheld controller of claim 2 wherein the first vibration source, the second vibration source, and the third vibration source are disposed in a plane.

4. The handheld controller of claim 3 further comprising a fourth vibration source, wherein the first vibration source, the second vibration source, the third vibration source, and the fourth vibration source form four corners of a tetrahedron.

5. The handheld controller of claim 1 wherein the mechanical structure comprises a vibration conducting material disposed between the first vibration source and the housing.

6. The handheld controller of claim 5 wherein the mechanical structure comprises the vibration conducting material disposed between the second vibration source and the housing.

7. The handheld controller of claim 1 wherein the controller is further configured to generate a combined vibration at a predetermined location on the housing.

8. A method of operating an array of haptic elements disposed in a handheld controller having a housing including an interior space, the method comprising:

generating a first vibration using a first vibration source, wherein the first vibration is characterized by a first phase;

generating a second vibration using a second vibration source, wherein the second vibration is characterized by a second phase different from the first phase;

operating a controller disposed in the housing and coupled to the first vibration source and the second vibration source, wherein the controller is configured to vary at least one of the first phase or the second phase;

propagating the first vibration through a first mechanical structure filling the interior space between the first vibration source and the housing;

propagating the second vibration through a second mechanical structure filling the interior space between the second vibration source and the housing; and

producing a combined vibration at an initial location on the housing.

9. The method of claim 8 further comprising modifying at least one of the first phase or the second phase.

10. The method of claim 9 further comprising translating the combined vibration to a subsequent location different from the initial location.
