Casio showed a prototype of a visible light communication system using smartphones at CES.
Visible light communication (VLC) transmits digital signals by flashing light in frequencies visible to the naked eye. VLC has potential applications in many fields including augmented reality (since it can use a wide range of light-producing sources including monitors, LED lighting and signage, and because it can be read from a distance without impacting people or electronic equipment).
Casio has been a member of the Visible Light Communications Consortium since it was initiated in 2004.
