Synthesizer interfaces using laser projection are nothing new. Jean Michelle Jarre was famous for playing around with such devices back in the eighties when I was a kid. Lenovo are not the first tech company to play around with interactive projected control surfaces either. This review (below) would suggest that they have not cracked it. But I still want one.
Being able to project video or a presentation on a wall from your phone sounds like fun. Being able to flip that around and project a computer keyboard onto the table sounds like even more fun. Being able to project a piano keyboard onto a table top and play some music with tolerably low latency sounds like as much fun as you could have from a mobile device. So I’m going to be watching this market very closely. My next smartphone might not be the S6 edge after all!
