Ok.... Not to ask stupid questions, but why would you need to have a screen that can have inputs from that many fingers at once? lol

playing a game with two people?
 
Good technology for times to come, and for early adopters I guess. Nevertheless, once that's implemented in a bigger system it really sounds useful.
 
Now I can multi touch using my hands and feet, 5 fingers left hand + 5 fingers right hand + 5 fingers left foot + 5 fingers right foot = 20 fingers.
 
Isn't mutli-touch detection kinda like counting. Once you figured out that 2 came after 1, and that 3 came after 2, is it really that impressive that 20 comes after 19? I mean really, all they've done is increased the processing power to track 20+ inputs instead of the 3 or 4 of previous devices, right?

And touch points? You mean my fingers are simply activating various points on a detection grid (like buttons or switches)? I suppose the detection had to be reduced to a discrete number at some point, but only 3358 touch points? That's 73x46 points. That's what, 3 every 2 centimeters or something? That's not a very precise surface. Maybe I'm just confused.
 
LOL Twenty fingers on a 22" display? Four full hands, trying to make different gestures? Are we talking about using this for a pre-school? LOL

Now, put this on a 60" display, and hang it up in a board room with multiple windows open so folks can work on different things at once.... maybe I can see it. But even still, then you'd have at least two people standing in front of the display to manipulate it...
 
It's forward thinking technology. Like for when conference rooms will have a touch screen for the table allowing multiple participants to interact. Pretty cool when you think of the applications.

^ this.

Not on 22" ... what the heck, what can you do with 2-20 hands on a 22" lcd? One is the driver, the other one looks and points, not work too. It'll be weird.

I believe you're thinking of the 20+ touch in a linear fashion rather than simultaneous. A lot of touch-screen devices can only track one touch at a time. If you touch with two fingers, it tends to jump back and forth. Multi-touch devices have started to become more common, and these can track, well, more than one touch at a time. Of course, 20+ is beyond their capacity.

So what are the potential applications of something like this? A touch-screen keyboard that could actually keep up with a proficient 10-finger typist. A collabortive screen where multiple people could input information or maninpulate objects all at the same time.

A lot of times, stuff like this will come out and people will treat it like a solution in search of a problem. That's not entirely untrue. Often times, the next great gadget is only possible once certain technological breakthroughs have been achieved. In fact, there was an article that came out when the iPad debutted pointing out that an iPad prototype was actually invented a decade or so earlier. However, it would not have been possible to create THE iPad because the technology did not exist yet.

I agree with this. An application on a conference table could be useful. Introducing a 20 touch display on a 22" is kind of silly. I guess you have to start somewhere...
 
This tech should be good for MS surface concept. I still remember seeing the concept of playing D&D on "surface" system. Yes... 20+ multitouch seems a little bite useless on up-right monitors... but... it can be very useful when the monitor is bigger and lying down as a table surface..
 
hhmmm.... imaging having a 50" monitor on the table surface.. having 2 3D glasses-equiped people trying to catch a fish from the monitor with their fingers...

hmmm...

kind of freaky...lol

I think the 22 inches is a bit small for 2 to fit comfortably and use it, but it's a good bench mark for number of inputs. I'd much rather see more inputs than needed rather than too few. It helps ensure future multi-touch displays will reach this 20 input goal (and hopefully be larger displays).

Or you're penis if you don't have 20 fingers.
