So, I think there are actually two different cases at play here: I'm afraid I haven't made my point clear, in the scenario described above the user is holding the pencil without it touching the screen at all, what I want is to trigger its haptic engine over-the-air in response to a finger touch (to compensate for the lack of a haptic engine in the iPad itself). It's been a very long time since I looked at this in detail, but I think there was actually some logic in the pencil itself that prevented it from vibrating when it wasn't in contact. Even in the other scenario, where both a finger and the pencil are touching the screen simultaneously, I can't get a finger touch to generate a buzz in the pencil. Only when I trigger the feedback from a pencil-generated touch does the pencil ever buzz. What did you try here? What I would expect to work here is generating view motion that moved to the point where the pencil was located, but it's possible we're
