Multi-Touch Calibration & Particle trail Demo

Below are a couple of videos that demonstration some functionality of the Bespoke Multi-Touch Framework.

The calibration system compensates for differences in alignment between the camera, surface, and projector. This algorithm takes a series of sample points to calculate offset vectors and interpolates the remaining screen coordinates. The system generates a lookup table for quick (no run-time calculation) conversion between camera and screen points, and the calibration table can be serialized for automatic loading.

 

The next video is a demo app that produces 3D particles at every multi-touch interaction point. This is an extremely simple application, and is included in the framework package — coming soon!

    Yes. That application requires (the now deprecated) XNA 2.0 and a camera (for multi-touch sensing) attached.

    If you really want to use the Multi-Touch Framework, I recommend that you compile the package and update the source to more recent versions of XNA and .NET.
