Hi everyone, first post. Bear with me. :)

I've been looking around the net for the last few days, but have been unable to find anything close to this idea. 

I was wondering if anyone had any ideas about how to set up an Interactive Visualisation Wall. That is, a projector aimed at a wall projecting say.... a lava lamp.. and a wiimote aimed so that the visualisation reacts when people interact with it. I've not even found non-interactive visualisations that I could run on the projector alone...

I ask because I am hosting a dinner party, and wondered about projecting various visuals onto the ceiling (bubbles, lava lamp, clouds etc) and whether a wiimote aimed at the dinner table could detect various natural infrared signals from people (or possible infrared leds on cutlery?!?) so that the ceiling projection reacts as the people eat their meal.

Lol, anyway, I'm no programmer, so I just thought I'd throw it out as a nice idea.

:)

Hi,

If you are planning to turn a projected screen on a wall, you can already easily do so with existing applications. All you need is just to face your Wiimote towards the wall and use some interactive software for the visualizations.

For your idea of projecting towards the ceiling and use the Wiimote to detect motions from people, it is certainly possible. However, it may end up just looking like random visualizations. :)

As a note, you may want to keep in mind that the Wiimote can only detect up to 4 IR blobs.

Coolies, thanks for the reply. I'll have a look around for some decent visualization software. (seem to be alot of crappy particle systems so far)

I walked through our local cinema the other day and they had a screen on the floor which was all water sloshing about in response to people walking on it, and it changed to balls and blocks that could be kicked around. Much better than sparse particle systems on monochrome backgrounds.

At the movie theater you probably saw something created with Open Frameworks. Open frameworks is really cool but it doesn't work with the Wii Remote. It works with standard web cams in general. And a library called openCV, short for open computer vision. You are proposing a very ambitious project for someone who is not a programmer but I wish you the best of luck.

I could build some full IR electronics into some table items for you if you have some money to spend but I think, a bread basket or a serving bowl would be a better choice then a utensil, for two reasons: one, it will be far easier to hide the electronics inside a basket or bowl, giving a very magical effect, and two, the Wii remote can only track 4 IR blobs maximum, as Boon already just mentioned.

Please send me an email at [email protected] or here on the board.

Once again good luck on your project it could be very cool.
