The Bespoke Multi-Touch Framework

I’m pleased to announce the initial release of the Bespoke Multi-Touch Framework. You can download the release from here. There are a two packages available: source+pre-compiled-binaries; and source-only.

6 sample applications are included:

  • HelloWorld (the canonical intro app and almost one-liner for interacting with the API – outputs to a text console)
  • CalibrationDemo
  • InkDemo (Pen-style interaction on a multi-touch surface)
  • ParticleTrails (presents smoke-like particle effects at each interaction point)
  • SurfaceSimon (2D XNA version of the classic 80s memory game – demonstrates multi-touch hit testing)
  • SurfaceCommand (3D XNA application demonstrating a simple real-time strategy (RTS) style multi-touch interface)

The samples (except for HelloWorld) employ the XNA presentation layer and share a common set of key-commands, such as:

V – Toggle display modes (there are 5 display modes, 4 debug + 1 normal)
C – Calibrate
Esc – Exit the app

This release is admittedly light on the documentation. I’m actively working on the doc and will be updating it soon. I’ve also left out WinForms and WPF sample applications, but these presentation layers should work without issue. The release is labeled 4.0 (instead of 1.0 for a typical intro release) because I’ve been working on this for awhile and have done a few internal releases. Aside from these few disclaimers, the code should at least compile cleanly and hook to a DirectShow capable video camera. Be certain to configure the Bespoke.MultiTouch.Framework.config file to match your multi-touch surface.

I hope you find the framework useful. If you have any questions please let me know.

Paul
