As far as #2 goes, sounds like you have a directional light source, such as a lamp. This causes your hand to cast a shadow on the paper. I too noticed this effect when I was doing the project (it was night with just one lamp shining directly on the paper as a light source). If you have light sources from multiple angles, or a very even but bright light source (like the sun shining off a white wall and making the whole room glow) this effect should be minimized because then your hand will not cause a large shadow, just your fingertips touching the paper. Hope this helps, good luck with your project!

Hi everybody! I’m new to the world of MTmini, and I’ve got a few questions that are probably pretty basic, but I feel like I’m missing something.
Question 1: How big does the box need to be? Is there a certain height that works best?
Question 2: When I place my hand on the paper and plexiglass I’ve taped together, I don’t just see the tips of my fingers, I see the whole hand. What am I doing wrong, lighting-wise?
I’m using a Microsoft Lifecam VX3000 on Windows 7, if that helps. I’d like to get it to work on Snow Leopard, but the camera isn’t agreeing with my computer there.
Thanks Seth. I Have try as you suggested but didnt work.
I modified the Xml file in several ocasions but wasnt able to change the default camera (iSight) or to browse to the next device connected through usb drive.
If you have any other idea on how could I make the shift for the additional camera on a Mac I’d appreciate it. Thanks!
Before I start this project, I only have a mac at home and I was wondering what the chances of a good mouse driver in mac for the mtmini.
I have been reading on these forums for a while but I can’t seem to find anything to fit the bill.
I know there is no click on the surface, which makes it difficult to do anything with it unless you used a tap for click and drag for moving the cursor. I want to replicate the functionality of the magic trackpad on mac with the multitouch gestures but I don’t know if there is anything currently to do it, I have been searching a while but I cant seem to find it.
This is the best community I have been looking through, even better than XDADevs, and that is fantastic,
Edit: I will try the tuio Mouse and tbeta, and see how that is although, if this is possible, it would be great, im sure heaps of people would go this over a magic trackpad, much cheaper, much more versatile!
