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.
