Abstract
A method for determining positions of fingers of a user is described. The method includes transmitting a power signal from a head mounted display (HMD) to provide power to a plurality of light emitters. The light emitters emit light in a sequence upon receiving the power signal. The method includes using the light emitted by the light emitters to determine a plurality of positions of the light emitters. The positions are used to play a game using the HMD.
