Hi everyone, I discovered this site sometime back and registered but I'm pretty sure I haven't posted anything yet. I started watching the hacks Johnny taped earlier last year and had been watching off and on to find updates. Now that I'm back on, I hope to learn more about the discoveries he and his team has made. Hopefully, I'll be able to contribute to the project(s) for the betterment of using such great technology to its fullest.

My initial vision for what the Wiimote can do is to use the fingertip recognition hand-in-hand with a flat OLED surface. This will accomplish the same effect as Microsoft's Surface.

At the very least, I hope to learn something new and I'm sure that won't be hard here.

Good to see you here Oliver. As you know, the site covers a pretty wide spectrum, so learning something new will be easy indeed.

Interactive multi touch surfaces are going to rock the world in the next few years. I like this project because I can be an open source contributor to such a technology leap.

Hi Oliver

Welcome (or should I say welcome back). I also joined recently. Your microsoft surface idea is good. I also thought of contributing to something like that (after I finish a huge "todo" list). The Idea seems really feasible and as I read more about how microsoft's concept not too hard a project.  A great link which explains how the microsoft table works for anyone who is interested is :

The thing I am puzzled about is why use a flat OLED instead of a projector (like microsoft)? I started reading about oleds on wiki and they sound like they fit specifications but seem expensive (because it is a new relativly technology).

Anyways welcome Oliver. You will find people here are very nice and helpful.

Projector is not a feasible way to go if you're looking for something compact. Unless you mess with your own optics, the projecting angle is going to be way too narrow.

Hi Wiweeyum,
I'm not sure it's not feasible. I think that it may be possible just by using mirrors (to get the distance).

hi all,
         Guess what i found. this dj table does a projection from below and wiimote from above (it seems like they used bits from an old type overhead projector). Here is the link:

anyone know more of this project (If they have detailed instructions on how they built it)

If you search for interactive tables in google, you can get a couple of pictures of tables that use mirrors. This would be the way to go for sure, but keep in mind that if anything is in the pathway of the reflected path, then you're going to have some issues.

I've been building a table using mirrors, and it's been a lot of trial and error. It will work, but it's taken a lot of tweaking. The math doesn't match up nearly as closely as I'd like.

Also, I think using multiple wiimotes will be necessary as well if you want to keep it cost effective.

I really don't have a lot of specifics to give you, but these are the issues I've run into myself. Just keep them in mind as you're working on it so that you don't have to stress yourself about what to do.
