Scratching Records in 3D Space
http://www.vimeo.com/4312616
This is an interesting idea by Vanderline. He comments:
I was playing around with some AR markers the other day and came up with this idea. taking just a plain old vinyl record and attaching an AR marker to the label you can track the record in 3D space.
The next question was, can you scratch the record? So by figuring out the velocity of the records rotation and applying it to the payback of the audio you can scratch. There is some digital noise that needs to be worked out, but sounds pretty good. Its still really hard to scratch, it takes some practice but is super fun. The next step is to figure out some nice triggers for different modes. I like the idea of not needing a turntable but the actual spinning of the record helps with the scratching and playback. I made a couple modes, one where the record is paused and you can just scratch through the song. The other looks for zero velocity for x time and then continues on with the song. If there is velocity you then are scratching and the audio is affected. I think that this project has some legs can’t wait to play more.

It’s already been done by numerous companies.VirtualDJ,is the best one by far.You can go to ant DJ gear web site and there enough to pick and choose from.But it is cool that you can make your own program. I wish I knew enough about computers that I could.

Also,what you are doing with the album and the video camera they have done with a time coded album,so the computer knows what position the stylus would be in if it were actually playing a song,and what it’s doing like scratching,spinning,sitting idle,spinning backwards or whatever.Any way have fun and good luck.

And it is cool you don’t need a turntable,or any thing.could you put the marker on your hand,and just move your hand to get yhe effect ? That would be awsome.And then it really would be a “Virtual DJ”
