Delphi productions came to us to design, direct, and program 4 multi touch tables and a 20 ft multi touch wall.  Since this was both Delphi and EC’s first multi-touch project there was quite a bit of research to be done.

We worked closely with Rick McKee, Delphi’s Executive Producer, to evaluate the various options for vendors that could supply the multi-touch hardware.  We decided to go with GestureTek because they offered the best combination of performance and support. From there we had the task of implementing the TUIO library within Flash, modifying our Flash interface to accept multi-touch commands.

Multi-touch commands are similar to an iPhone.  For instance, you can grab an image with 2 fingers and rotate it or scale it.  And even more importantly, we used multi-touch to allow a number of people (up to eight) to interact with the screen at once.

Using conventional computers, it is not even possible to prototype multi-touch interactions. So we had to get a test table at our studio for the 6 weeks prior to the show.

With this set up we were able to design and program the interface which included: a 3D interface to rotate and scale Medtronic devices, a fun drawing application, a hockey game, and a deep content area with presentations, video and audio.

Delphi producer, Jodie Marko, managed all of the content from the various Medtronic clients and insured that the content would be legible on the touch screens.  Jodie also designed the information flow and categorization of the interface. With over 90 pages of content that needed daily updates, this was no small feat.
