   Multi-Touch Interaction
  Just check ">THIS out!I don't know if this is old or not, but it would definetly change the way we interact with a computer, it's just awesome technology!There are so many new things that this could add to games and applications in general...Oh well, can't wait till it becomes popular :)   
  I saw that a while ago, pretty awesome stuff.Now all we need are Holodecks!Dave   ;Quote:Original post by DaveNow all we need are Holodecks!I think the more difficult thing about that would be keeping the person in the same place even as the person walks etc. And what would happen if the person walks agains a wall?I think 'virtual reality' things will only be achieved with some kind of thing like in the Matrix movie hahah (not necessarily plugin in something directly into your brain)I could be wrong though.   ;">GroupLab Diamond TouchWarcraft 3 game table prototypeMicrosoft Gaming InnovationThe last video is about a year and a half old (I think) and does not represent the current state of the technology, not by a long shot -- MS' is at least as good as Apple's. I know because I'm working on it over summer [grin] Unfortunately, I'm under NDA against saying more. But since getting hired I've been keeping an eye on what other people are doing. It looks like the technology appeared at quite a lot of different places more or less simultaneous, though implementation details vary. I know for a fact that the Apple and MS implementations use very different approaches, for example.   ;  The thing with the map and the pictures sold it for me. I can actually see interacting with a computer this way. It's like Minority Report, only without Tom Cruise's craziness[smile]   ;Quote:Original post by Cold_SteelIt's like Minority ReportBeaten to it. Dammit!It would be fun to have a try mind, watching it in Minority Report didnt make it seem all that fun, but watching that video, shifting round the photos, the little games, just makes it seem more, well, interactive [smile]   ;  Well... humm, I've become very interested in doing something similar to this just now haha.How would you go about figuring out the distance a finger is from the camera?I mean, let's imagine I put the camera on the right side of my monitor, I can easily figure out the y (vertical) position of each finger, but how would I know the x (horizontal) position?Also, this would have the obvious flaw that the some fingers could be behind other fingers.The only solution I can see to solve this problem would be 2 cameras, one on the right/left side, and another one at the top. I honestly don't think this would be too dificult to do, what do you guys think?   ;Quote:Original post by Kamikaze15The only solution I can see to solve this problem would be 2 cameras, one on the right/left side, and another one at the top. I honestly don't think this would be too dificult to do, what do you guys think? I think you're significantly underestimating the difficulty. You need a person or several who know machine vision and can do it well. Watch the MS video, watch how it track the finger. That's not limited to a single finger; it can cover a lot of individual contacts on screen (again, I can't give numbers). Notice that the tracking isn't affected by shadows. Recognizing multiple objects means being able to do it generally, as well as understand the zoom style motions that the Apple video was using. And doing it in real time is very difficult indeed, you need to be rather efficient about it.   ;  Am I the only one that just cant get over how ridiculously flashback-inducingly trippy that second demo was?   ;I posted this last year.
