how many fingers does your multitouch pc support at the same time?

    Last week I got the Acer 1825ptz, a small convertible similar to the device the pdc attendants were given last year. I was interested in checking out the new multitouch capabilities in wpf4.

    I was a bit surprised when I recognized that the device, which is advertised as multitouch capable, actually supports only two fingers. Ok, that's more than one, so they can call it multi, I suppose. Still I was expecting something more.

     

    Does anyone own some of those hp touchsmarts or similar devices? What are your experiences? What is the maximum number of fingers supported on the multitouch pcs or screens usually these days?

    Before I had the PDC Tablet I had an HP TX2 which supported 4 touch points.  ( At the moment I am finding that two touch points is sufficient for most development purposes)

    I believe the norm is 2, and it's generally sufficient.

    I'm fairly sure I've used at least five fingers in MS Paint on my EeePC Multitouch -- I shall check this evening assuming I can wrench it away from the kids for a few minutes.

    I don't have a touch device, but I believe the standard is two. It lets you do the moving and resizing gestures, which seem to be all people need.

    Good Lord -- I've just checked my touch PC and it does indeed only support 2 fingers!  Why on earth did I believe I had used up to five?

    I must be getting old -- my mind's obviously not what it used to be.  Perplexed

    For a paint application you can set the application to track each finger. In most other typical applications you typically have the motion detectors in the top left and right hand corners, so any more than two fingers results in fingers blocking the path of a motion detector and the application loses track of what it is meant to be tracking and you get jerky and wierd behavior
