Abstract
A hand-held controller includes a handle extending in a longitudinal direction. The handle is shaped and dimensioned to be grasped by a user's hand. A ring is attached to an end of the handle and surrounds a thumb of the user when the handle is grasped by the user's hand. The ring has an annular surface that defines a plane that forms a predetermined angle with respect to the longitudinal direction, and a curved outer surface. Light sources are mounted on the curved outer surface and configured to emit light to be captured by an imaging device for tracking a position or orientation of the hand-held controller. The light is emitted in a direction normal to the curved outer surface.
Claims20
A hand-held controller comprising:
- a handle extending in a longitudinal direction;
- a ring attached to a distal end of the handle, the ring defining a plane that forms a predetermined angle with respect to the longitudinal direction, the ring having a curved outer surface;
- and
- a plurality of electromagnetic wave sources mounted at different locations on the curved outer surface and configured to emit electromagnetic waves to be captured by an imaging device for tracking a position or orientation of the hand-held controller.
A system, comprising:
- a hand-held controller comprising:
- a handle extending in a longitudinal direction;
- a ring attached to a distal end of the handle, the ring defining a plane that forms a predetermined angle with respect to the longitudinal direction, the ring having a curved outer surface;
- and
- a plurality of electromagnetic wave sources mounted at different locations on the curved outer surface and configured to emit electromagnetic waves;
- and
- an imaging device configured to capture one or more of the electromagnetic waves for tracking a position or orientation of the hand-held controller.
