One of my friend is interested in a DIY virtual laser keyboard, which has been purchased by him for some days.

I noticed the item but confused about it in some points. These points are based on both computer gamers we are.
1. Laser keyboard is harmful to our bodies though it's too cool. Short time of using is okay. Long period of using is trouble. Laser rays is harmful to people? I don't know.
2. Laser keyboard is like a paper. No any tacticle feeling so that we are unable to knock at them without glancing at the keyboard. Playing games seems to be too hard.
3. Laser keyboard exists in some fixed situation. It must be in a dark room, the keyboard must be supplied by power source and the most significant point is that you have to find an excellent horizontal surface for projection.
Guys what do you think of it?
