Dartmouth researchers have proposed an integrated networking and sensing environment, or ‘smart space’, that uses light to wirelessly send information between personal computers and smart devices. The integrated visible light communication project or iVLC, uses an experimental ‘smart space’ that contains a combination of algorithms, ceiling-mounted LEDs and light sensors embedded in floors and smart devices.
Currently, visible light communication (VLC) data transmission ceases when the light is blocked by shadows or other obstacles. Dartmouth’s ‘smart space’ track users’ gestures and separate shadows from light to continuously transmit data. The results from the team’s simulation tests are positive, and the researchers are working towards building a proof-of-concept iVLC testbed.
