Display System That Knows Who You Are

lee1 writes "New Scientist reports on an 'interactive computer display that keeps track of multiple users by differentiating between their touch'. The system consists of a touch-sensitive screen that can be operated by several users simultaneously. When a user touches the screen an electrical signal is sent through their body and picked up by a receiver located in their chair, telling a computer precisely where the screen was touched and by whom. Applications could include system access control, safer vehicle controls, and smarter videogames. The bottom line, in the words of one of the inventors: 'If the controls know who is operating them, they can behave appropriately.' The movie even has funkier than average background music."

      "It was terribly dangerous to let your thoughts wander when you were telecommuting or within range of a telescreen. The smallest thing could give you away. A nervous tic, an unconscious look of bedroom eyes, a habit of muttering to yourself, anything that carried with it the suggestion of looking at b00bies, or having something to hide from HR. In any case, to sport wood at the office, was itself a punishable offense. There was even a word for it in Cubespeak: pantcrime."

    Of course the chair would also need to be able to read the RFID tag implanted in your butt to solve the Musical Chairs Problem.

    1. Re:The Musical Chairs Problem by CastrTroy · · Score: 3, Interesting

      Maybe the system doesn't care that jim or bob is touching the screen, but rather that seat 1 or seat 3 is touching the screen. However, this also creates the problem that everyone must be sitting on a chair. Maybe they could just have something you stick on your finger tip, or have each user have a separate stylus. Would be a lot easier to implement than tranmitting the signal through the person, and hoping that they are sitting in the chair.

      ...RFID tag implanted in your butt...

      Why are you people so pessimist? They have no need for such invasive measures... I think they're just going to use something similar to an anal probe, for which everyone already have a proper receiver. Actually, it seems like a pretty good idea, just think about it. It's universal, not limited to humans - maybe soon we can see fish using touch screens. Wicked, eh? Some may even get extra pleasure from using it, besides the joy of using a touch screen, that is - I'm pretty sure we can expect an increase in productivity in many offices. Only God knows what else can this thing bring in the future...

  12. Not a great example movie by Shawn+Parr · · Score: 2, Insightful
    Wow, that movie doesn't really show how the user detection works at all really. The section with the two different boxes was supposed to I guess, but since both users just made the boxes jiggle around it wasn't effective.

    Definitely we can see that multiple input works, but that has been shown within the last year or two already, so that is nothing new.

    You would think that if the major new feature is this user detection, they would have used different colors for the different users, or found some other method to really show off that it doing one thing for one user (resizing/moving windows for instance), while doing something else for the other user (scrolling through a window, selecting options in a different window, etc.).

    And what was with the staged beverage spill. For a technology demo that was pretty weird.

    I did find it ironic that the entire demo was done in XP, but they used Apple's website as their demo material.

    1. Re:Not a great example movie by electron_plumber · · Score: 3, Informative
      The boxes are in different colors - it's just hard to see. (We're researchers - not videographers!) Oh, and the spill was to show robustness. In the classic UIST video, an especially robust DiamondTouch is lit on fire (don't try this at home), and people continue to use it as the flames sizzle...

      In any case, DiamondTouch is not really new. It is already a product which you can buy today! The article in New Scientist was originally going to focus on DT Controls, which is very new. It uses the same idenity trick as DiamondTouch, but applies it to non-virtual controls, such as in an airplane cockpit or on an automobile dashboard. One of the killer apps is allowing a passenger to operate a vehicle navigation system while the car is moving. (Typically, the system is locked out to prevent use by the driver.) The system really only knows which seat the touch is coming from, so it's not particularly Orwellian...
