The data transmission stops whenever people’s movements, shadows or other obstacles block the light. One of the problems in more effectively using Visible Light Communication to send data wirelessly involves line of sight interference. This allows a continuous flow of data wirelessly among personal computers and smart devices in rooms, buildings, trains and other indoor places. The Smart Spaces track users’ gestures and separate shadows from light. The integrated Visible Light Communication project is the first time an integrated networking and sensing environment has been proposed for sending information by light. “This is actually a huge leap forward,” she said. That research is pushing that progress further to include the use of light to communicate human behavior as well. Her research team in October began tackling the idea of integrating human sensing with the data communication. “The progress those researchers made has developed a communication system that is much like a wired network,” said Zhou. Zhou, who co-directs the Dartmouth research with Professor Andrew Campbell, described the UK researchers as the pioneers in light communication. Key to that discovery is a research group based in the University of Edinberg. Other researchers already established the use the light for data communication. It is sort of a buy one and get one free approach,” Xia Zhou, Assistant Professor of Computer Science at Dartmouth University, told TechNewsWorld. The new thing here is to reuse the light for both deliveries. “In our project the revolutionary idea is to combine communication with human sensing. The Smart Spaces technology allows the interplay of algorithms, ceiling-mounted LEDs (light-emitting diodes) and light sensors embedded in floors and in smart devices. The smart spaces overcome existing limitations in other low-tech approaches that stops data transmission whenever the light is blocked by people’s movements, shadows or other obstacles. Thus, the light spectrum is able to carry high-speed data wirelessly without interruption between smart devices. This technology enables so-called smart spaces to separate shadows from light in real time. The integrated Visible Light Communication project (iVLC) marks the first time an integrated networking and sensing environment has been proposed for sending information by light, according to Dartmouth University researchers. The three-month-old research pushes the envelope beyond advancements already made by researchers in the UK, at the University of Edinberg. Dartmouth University researchers are shining a new light on using “smart spaces” in ambient room lighting to transmit both data and human gestures.
