I feel like I hit what I'm aiming at maybe half the time when I turn a laser on.
That's why all of the laser UI is designed so you can point in the general direction of something, and then correct to where you meant to point. Almost all objects respond to the laser entering them or going up in them, not the laser going down in them.
In the case of a wall-painting app, I might use a quasimode. The laser would only leave paint while you're holding down a button on the iPad. For example, the iPad would have a color palette that you could reach from your left thumb, and you would have to hold your thumb down on a color while painting. (Like photoshop, it would probably show the outline of the brush as a "cursor" even when you're not holding down the button, so you can see where the paint would appear.)
I wanted the precision of drawing with your hand vs. the shakiness and imprecision of the laser.
Our laser tracking is pretty crude right now, but there's a lot you can do to smooth the signal in something like a painting app. Heavily time-averaging the point would give you a slow but precise line that would "chase" the laser point.

To answer your question: because I don't know how to interact with the laser system :). Also, I wanted the precision of drawing with your hand vs. the shakiness and imprecision of the laser. I feel like I hit what I'm aiming at maybe half the time when I turn a laser on.
