  • Patent number: 11914786
    Abstract: Provided is a gesture recognition (GR) device that includes a circuit board on which a plurality of light sources are mounted. A first light source is side-mounted at a tip of a second unit of the circuit board, and the set of second light sources is mounted at right angles at top and bottom surfaces of the second unit. A first pair from the set of second light sources is positioned adjacent to the side-mounted first light source. The plurality of light sources are controlled to generate multiple lighting effects for the tip based on assertion signals generated at a first unit of the circuit board. A first lighting effect corresponds to a directional beam generated by the first light source. A set of second lighting effects, which remains unblocked by the side-mounted first light source, corresponds to a multi-color illumination generated by the set of second light sources.
