"Optone project has been started to bring in dynamic change of colors such as a sky at sunset into light of daily life. Instead of switching on and off, new controls of lightl by physical action such as swinging or rotating are invented to enjoy colors. The designer has been exploring quality of action and experience of light besides that of traditional light system, and developing not only form of light product but also original color control algorithm with sensor technology for full color LED light source."
