To use this, one would wear a laser-pointing device attached to their forefinger and use their thumb and middle finger to engage this.
With this, they could interact with a giant interface screen projected on the wall. The projection could also be used for videos,
music visualizations, and enlargements of the instructor on camera.
Users either liked the idea of the projector or hated it, but they didn't feel
as though they would be comfortable trying to point-and-shoot at such a large screen. They also felt the students might oddly mimic this movement.
