Here are some early tests and prototypes of my first homemade multitouch surface on a small and large scale.
Passing controller data from Arduino to Processing. The arcade button controls the appearance of the white dot on the screen and two potentiometers control movement left and right.
IBM Think! was an exhibit / interactive experience staged in an underground parking garage at Lincoln Center in NYC. The entrance ramp was flanked by a huge LED wall which streamed a mix of prepared video and real time data (pollution index, traffic data etc). Inside the exhibit were large vertical LCD panels and mirrored walls which transformed the space into an immersive presentation that surrounded the audience with choreographed sound, video and text. When the video presentation ended the screens essentially turned into large interactive iPad-like devices which the exhibit-goers used to explore content. This was a very well crafted exhibit full of useful information and technology.
