Dartmouth Researchers Develop Smart LED System to Monitor Human Movement

A team from Dartmouth College has developed LiSense, the first light-sensing system capable of continuously and unobtrusively reconstructing human postures, marking a significant advancement in creating smart environments that respond to human gestures. This innovative system leverages visible light communication (VLC) to convert light intensity variations into data, enabling devices like smart glasses and watches to interact with users without the need for cameras or wearable sensors. The researchers achieved real-time movement tracking using LED lights and photodiodes, overcoming challenges related to shadow patterns created by multiple light sources. This technology opens up new possibilities for natural interaction with smart appliances and could enhance passive health monitoring by fostering healthier lifestyles. Findings from this research will be showcased on September 9 at the MobiCom conference.
