As Electrons and Holes blog mentions, NY Times has an article on Canesta 11-year history. The article is accompanied by two video demos showing gaiming and TV remote control applications.
Over the years, Canesta has raised about $60M. Quanta and Honda are among the investors. Quanta expects to sell laptops with 3D camera later this year. Canesta hopes to piggyback on the exploding interest in the technology and pop low-cost chips into every device it can.
