3M Says Its Multi-Touch System Means Almost No Lag

Posted by timothy on from the so-why-don'tcha-marry-it? dept.

jonniee writes "3M has rolled out a 22-inch digital display capable of 20-finger multi-touch input with less than 6 millisecond response time. The monitor incorporates 3M's Projected Capacitive Technology based on mutual capacitance operation theory. The result produces a silky smooth response that has almost no lag in execution."

    ...20-finger multi-touch input

    Wow! Does that mean you can use your toes for input as well as your fingers?

      How about two people using a screen at the same time when talking about something on the screen. Both are turning objects that are being rendered, to view different angles and the like.

      Seems that 20 inputs for a 22 inch screen is the most fingers that would be able to realistically get to it... Any more than two people huddling around the same screen would mean it needs to be significantly bigger in size than 22 inches.

    Now I can finally use both my fingers and toes to play games on my 22" monitor!

    Still not perfect, though. I really need 21 point for reasons I won't go into.

    Assuming you can set the screen down flat, you can do a lot of multiplayer games with this. Like duet piano, or playing Magic the Gathering with two players (and "tapping" virtual cards couldn't be any more realistic too!)

    about 150ms for instinctive (spinal/stem) response, 300ms for a conscious(cortical) response, 400ms to be aware of what you decided to do.

    They also made some great boardgames back in the day.

    A lot of it is down to the famous 15 percent rule--the idea that their researchers and engineers are free to spend 15% of their time pursuing their own ideas.

    Some of the younger developers at our place are in awe of Google having "invented" the whole one day a week innovating thing, and are shocked that some of the less cool corporations were doing this back in the sixties.
