Comment Enhanced Pool Table (Score 1) 57
I've always wanted something like this projector + camera shining down on a pool table.
It could record all of the shots, and easily show you a prior table position so you could "un-do" a shot as well as re-play slow motion video of a "break" or other action. Based on varying games, it could count and keep score (cutthroat, multiple iterations of "4 ball run", etc etc) by just displaying the scores somewhere on the table.
For interactivity, it could "visualize" the line of an intended ball strike by viewing your cue stick and anticipating the output (it wouldn't be perfect with only a top-view camera, but good enough). Once you find your desired "line" a voice or other gesture control could "freeze" the drawn lines, allowing you to more easily aim.
Fun stuff, and I didn't even watch the video (:
