1. University of Illinois at Chicago Electronic Visualization Laboratory (EVL) The magic touch… This semester’s tools: –Processing –TacTile Processing is an open source programming language. –Essentially a blend between Java and scripts. –Straightforward and easy to use –Advanced users still have all the Java capabilities. TacTile is a multi-touch table developed here at EVL. –Uses IR light to generate touch feed back. –Daubed just last semester at SC 2008.

2. University of Illinois at Chicago Electronic Visualization Laboratory (EVL) Gotta walk, before you run… Multi-Touch Pad –For all those who don’t have a tacTile at home ~.- –Will need two components: Touch Tracker TouchAPI Development will occur on the Multi-Touch Pads –Highly recommend you build this ASP –Most of your development time and testing will be done with the Multi-Touch Pads.

4. University of Illinois at Chicago Electronic Visualization Laboratory (EVL) TouchAPI The Idea –Written to be a library that could be added to Processing –Allows users to communicate between a Touch Server and Processing Application Do we have to write a Touch Server?! –TacTile has its own touch server –The Multi-Touch Pad drivers will also come with an application that will act as a touch server on your personal computers. What does this mean?! –During development: the TouchAPI will facilitate communication between your Processing Application and the Multi-Touch Pad. –Presentation time: the TouchAPI will facilitate communication between your Processing Application and TacTile

5. University of Illinois at Chicago Electronic Visualization Laboratory (EVL) Do not do it’s a trap! Processing –Processing does not need to be installed. –The Processing folder is called the “sketchbook” –The “sketchbook”, must contain all the libraries you call upon. –Adding multiple files is easy. Processing takes care of the linking TacTile –The methods to access intensity. –FingerIDs across zones.
