Abstract
A hand-held controller is enables a user to manipulate objects in a VR environment with hand movement. The hand-held controller includes a handle, a ring attached to an end of the handle and one or more light emitting diodes (LEDs). The handle has appropriate shape and dimensions so that it can be grasped by the user's hand. The ring has an outer body that includes an inner surface that is formed with one or more concave dome and an outer surface facing away from the inner surface. Each of the one or more LED is mounted under a concaved dome. Light emitted from the LED spreads at the concaved dome to form uniform illuminous intensity. The light transmits out of the body through the outer surface of the outer body. The light can be captured by a camera for tracking the hand-held controller.
