The iPad is great for sketching and taking notes, but could it be even better if it was able to respond to pen pressure?

We plan to release this capability as a free software library so it can be included in any application. However, this may not be possible for a while as the library now uses a private function call to access the required information.

We hope the UIKit framework can be updated to make the required information available, but there are no guarantees this will ever happen. In the meantime, we hope the video provides some insight into what is possible on this amazing piece of hardware.

Note: The small drawing lag in the video is an issue with our demo application code, and isn't a limitation of the iPad or the pressure-sensitive library.
