Patent ID: 8795077

Claim:
A personal control mechanism comprising: a pair of identical controllers, each of the controllers including: a housing having at least a forward end, a top surface and a bottom surface, the forward end including an emitter emitting a light to be captured by a receiver remotely located, the top surface including a number of buttons and a joystick all operable by a finger of one hand, the bottom surface including a trigger operable by another finger of the hand, the housing having a holding portion designed in a way that the trigger, buttons and the joystick are operated by respective fingers of the hand when the holding portion is being held in the hand; a plurality of inertial sensors producing sensing signals that are sufficient to derive relative positions and orientation in six degrees of freedom by a processing unit; and an indicator indicating the each of the controllers is being held in a left hand or a right hand when both of the controllers are being held by one user and indicating the each of the controllers is being held by which user when the two controllers are respectively being held by two users, wherein the indicator is turned on automatically by the processing unit configured to receive independently and process the sensing signals from both of the controllers in conjunction of determined respective coordinates of illuminations from the controllers in an image from a camera provided in vicinity, wherein the sensing signals of each of the controllers are received in the processing unit configured to generate a virtual interactive environment in which at least one of objects is responsive to the sensing signals of either one of the controllers.
