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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Signal generation and detector systems and methods for determining positions of fingers of a user","description":"A method for determining positions of fingers of a user is described.
