This paper presents VINCE - a novel Visible Light Communication (VLC) system for smartphones. VINCE encodes information as different brightness levels of smartphone screens, while receivers capture the light signal via light sensors. We experimentally profile the impact of screen brightness levels and refresh rates of smartphones, and then use the results to guide the design of light intensity encoding scheme of VINCE. We adopt several signal processing techniques and empirically derive a model
