Haptic feedback only on touch-down event?

[chrisballinger]

I'm curious if you've tried only doing the feedback on touch-down only, and not on touch-up.

If I touch the key fast enough I only seem to get the touch-down feedback, which makes the response feel inconsistent sometimes. Then I started wondering what it felt like if was possible to only send one haptic event instead of two.

It is using both touch down and up and triggers different type of haptic feedbacks, as long as these two events are not happening in a very short period, which is 50ms now. This is intentional implementation to address #3.

I think it’s reasonable behavior, however this is fixed value so we may want to adjust or make it configurable.

For quick taps, personally, I find one key stroke (down) more natural with a better feeling. I have added three more cases to the app such as Down/Up key event (default), Down Key event or Up key event to keep experimenting.

@munsuri can you create also a pull request for your changes?

It'd be nice to have this be configurable, as I'd prefer a much longer time. Asking the user to rebuild seems like kinda a hassle. I'd love to contribute, but Objective-C is unfortunately outside my wheelhouse for now.

I played around with the kMinimumActuationInterval a bit and found that 200ms gives a pretty good experience for me personally. Anything longer, I experience as a proper key press that should have down and up feedback. Anything shorter, I experience as a tap, for which a single feedback is sufficient.

Also, major thumbs up to @niw for making this easy to compile (without any Ruby or XCode experience)!
