My first WPF 4.0/Windows 7 multitouch application

So I finally bought an Acer T230H multitouch enabled monitor that is supported by Windows 7. Actually, it is a dual touch but that’s enough. (for more on multitouch input devices for Windows 7 see my previous article).

On the good side it is a decent 1900x1080 monitor, not too expensive and multitouch works even under VMWare Workstation 7. On the bad side I knew it has some problems following fingers. Actually sometimes it gets just confused. That’s not a problem for a project I am working on but nevertheless I was curious.

Hence I created my first multitouch application that visualizes touch positions from monitor. Here is a screenshot featuring two fingers:

The application itself supports two different colors because I was interested only in two (no problem adding more if somebody wants me to). So, try the application and see how good or bad does your multitouch input device. Note, .net framework 4.0 RC is required.

As per my Acer T230H: indeed it has problems that usually manifest when fingers are nearby. And sometimes it just gets confused. Heck, it is one of the first multitouch monitors and a cheap one.

Have fun multitouching!
