(Not really tablet-related, but related to NumptyPhysics, which has been initially written for the tablets. Feel free to skip :)
The summer semester is in full swing, and we have been working on our HCI multi-touch seminar work for the last few weeks. We plan on extending Tim Edmonds' NumptyPhysics to work on multi-touch tables and adopt the UI accordingly to take advantage of multiple input cursors. We did a trial run on a real table last week:
The cude currently only emulates mouse events, but will allow real multi-touch input soon. We will release the code as soon as some bugs have been fixed and the code design got a bit more stable.
