    摘要: A hand-held controller includes a handle extending in a longitudinal direction. The handle is shaped and dimensioned to be grasped by a hand of a user. A ring is attached to an end of the handle and surrounds a thumb of the user when the handle is grasped by the hand of the user. The ring has an annular surface defining a plane that forms a predetermined angle with respect to the longitudinal direction. The ring also has a curved outer surface. A sensor is embedded within the ring or mounted on a side surface of the handle to detect whether the hand of the user grasping the handle is a right hand of the user or a left hand of the user.
