VLC-based light-weight portable user interface for in-house applications

Advances in solid-state lighting have overcome common limitations on optical wireless such as power needs due to light dispersion. It’s been recently proposed the modification of lamp’s drivers to take advantages of its switching behaviour to include data links maintaining the illumination control they provide. In this paper, a remote access application using visible light communications is presented that provides wireless access to a remote computer using a touchscreen as user interface.
