This is a bit of a crazy idea, but I think it would make an interesting variation on the current multi-touch format. The basic idea is to build a multi-touch table that tilts in several directions, and use the wiimote to relay tilt information. Obviously you’ll have to be quite inventive with the design of the table so that the projected image isn’t affected by the tilting, but I think the tilting information might be useful for some applications.

For example, you could use a sideways tilt to turn the pages of a virtual book, or to navigate through a map or maze. Or if you’ve got a drawing program, a simple tilt could clear the screen. Does anyone else have any crazy ideas for integrating tilting into multi-touch?

I love this idea I am sure it would not be to hard to archive with an accelerometer or wiimote.

But the hard part is how to deal with moving the projector or camera if you are using a vision based system :(

You would need some sort of pivoting system that the camera/projector sit on that tilts with surface.

Keep thinking crazy… thats how the future is made

We already built a tilting table: See http://mi-lab.org/projects/flux/ We used an accelerometer to track its orientation! It features FTIR and ANOTO Pen tracking and has also an inbuilt Sensorbar for the use with Wii-Controllers!

The main challenge is, as you said, to built the table in a way so its easy to tilt (weight of frame) and how you mount the projector so it doesn’t move inside the table but its definitely doable! If you’d like to try yourself I’d recommend going for lightweight components (frame + LED-projector)!

If you check out Johnny Lee’s Wiimote stuff you’ll find that he has developed throwable displays! http://procrastineering.blogspot.com/ so this idea could be implemented into the tilt MT table and digitally change the projected geometry, perhaps simpler than mechanically swinging the beamer, Even better would be hacking into the key stone feature, unfortunatly most small beamers only have horizontal keystone and not vert, Some also support there own geometry adjustment. I’d love to see that lcd or dlp plate tracking the tables motion, but id probly burn out my retina!

Get your gimble’s on the go and its digital labarinth ahoy!

Your tilting table is very inspiring!
I wanted to build one too, and seeing this thread and your FLUX project, I feel confident it can be done

As far as mirror and camera/projector configuration, do you have any details posted somewhere?

Thanks! Great work
