- I finally bit the bullet and assembled the Powerglove and SEGA units
- for my PC. For those of you too timid to give it a try, even this
- liberal arts major was able to assemble it with only a few tantrums.
-
- Now that I am feeling cocky, I would like to build another "VR" type
- of interface. I vaguely remember reading a description of a home brew
- touch screen interface in _Circuit Cellar_ (???) by Garcia (??) a few
- years ago. The author included plans for a grid of photo-cells and
- lights mounted in a frame places over the monitor. When the light
- path was broken, a signal was sent to the computer so that the
- location could be calculated. I think the author mentioned
- constructing multiple frames to create a type of "volumetric touch
- screen."
-
- First, would this work in principle?
-
- Second, my trip to the library was unsucessful. Can someone give me a
- lead on the correct spelling/title of the author/magazine or any other
- leads for an interface of this type.
