Update

It's been a while since our last update, but we sure made some progress in the meanwhile.

We completely closed the table with wooden panels, so no external light can disturb with the working of out table.





We successfully installed MultTouchVista and made it work with Tbeta as an input device (sends TUIO to MultiTouchVista).
So now we use the standard built in multi-touch function of Windows7.

We installed google earth to play around with :P, and we also tried to install Nasa Worlwind and the multi-touch plugin, but for some reason (we think: not supported driver) it won't start up at all, so we can't test with it.

We installed Bumptop for a more multi-touch experience, it has some cool functions.

The frame is almost finished

This is why we recommend to first draw the multi touch screen on a computer, so you know what to expect, and so you can overlook problems more easier and you can handle with them before the problem really occurs.

Difficulties with projector in frame

After noticing the problem it wasn't so hard to figure out a way to solve this problem.
We got back to the drawing board and adapted the first prototype sketch we drew.

This is our solution to the problem,




- We raised the projector 4,5cm above the top of the frame, this is to get the proper image projection size.
- We also had to move the projector 23,3cm to the back to fit the image centered onto the surface.
- We figured out a way to stabilize the projector. We made a support under the projector where he can rest on, and we are going to attach the projector to the back of the frame.

See sketches (support and attachment in more dark brown color).

Prototype

This is the prototype we started from.
The sketch was to see how it would look like, and this is what we came up whit. (created with Skechup )

If the build go's along pictures will follow of the real frame.
