Hardware.Info posted Celluon Epic and EvoMouse review: virtual keyboard and touchpad
A quote from the article:

A red laser created the virtual keyboard and IR was used for detecting each keystroke. We recently had the opportunity to test its successor, along with a touchpad mouse controller from the same company.
