Abstract
A Li-Fi enabled stylus includes a Li-Fi receiver, a stylus memory, a Li-Fi source, and a movable lens. The receiver detects multiple channels of information-encoded light from a first Li-Fi enabled display. The stylus memory stores information contained in the multiple channels of information-encoded light from the first Li-Fi enabled display. The Li-Fi source transmits the information stored in the stylus memory onto a second Li-Fi enabled display via multiple channels of information-encoded light. The movable lens adjusts a range of view of the Li-Fi enabled stylus.
