How do you think about the philosophy of pointer prediction as in; however good you get, you'll never get good at predicting when a user decides to stop and do something (that's like predicting the stock market) unless you can also predict intent based on task context.

Totally! If you view source on the html you’ll find a function called onRest that is called in a variety of conditions to halt the prediction. Mainly when there has been an longer than usual period since input data.

Ah, thanks for the shout. You can play here: andymatuschak.org/scrying-pen/ Fun memory: in ~2013, when I was at Apple, I made all scroll views predict future touches to get a tighter response. We pulled it before shipping—not a big enough diff. There's an API for this now for drawing.

I’m guessing this is the talk? developer.apple.com/videos/play/ww There’s discussion of deceleration rates for projecting positions of animated objects, but not for estimating when a touch sequence is coming to a stop. Haven’t seen that mentioned in a talk, but don’t watch WWDC anymore.

Throw projection and touch sequence prediction are similar in so far as they’re modeling inertia - either of the designed digital object being thrown, or the physical inertia of a body / hand performing the input. Predicting much beyond that can add an undesirable feedback loop.
