-What's a MTmini?-
-------------------------------------
Don't have a Multitouch Table yet? Have one,
but need something smaller for testing?
Building a small portable multitouch pad will
allow you to test software and experiment on
a smaller scale while building your full
table or when away from your multitouch
screen. Have fun and make a MTmini! This uses
Front Diffused Illumination, with normal
ambient light (infrared not required or
needed) and a normal off-the-shelf webcam (IR
filter can still be in place).
-How's it Work?-
-------------------------------------
For this to work, all you need is a room with
(at least) some light. The results will be
best when the room lighting is even (no
bright lights shinning from one direction
onto the multitouch pad).
When you place you fingers on the surface,
shadows are created where your fingers are.
The webcam sees these shadows and sends the
image to the tracking software which tracks
the shadows as they move on the surface.
It's important to try different lighting
setups and to configure the software in order
to get the best results.

This is my video response, summarizing the
creation of my MT Mini multi-touch interface
and some demonstration of it in use. I'm
still working on my editing skills and the
interface could use some fine-tuning, but I
was pleased to have it actually working
without a lot of effort. If you want to skip
the building and commentary, jump to 3:26 in
the video.

| My MTmini box |

A very simple MTmini implementation. Finger
tracing seems to work nicely, but I recon the
suggested Acrylic or glass panel will up the
performance further. Also a better cam won't
hurt lol.
Building process:
- Open the top of the cardboard box.
- Place a webcam on the bottom, try to center
it as much as you can. Make a small hole in
one of the sides of the box to guide the
USB/FireWire cable through.
- Take a plastic binder with at least 'some'
strength.
- Lay it on top of the box and tape it up.
- Lay the tracing paper on top of the plastic
binder and tape it too.
And that's basically it. For more information
