    A few months back, folk were wondering what ipad touch limits were. On the ipod/iphone, it's a max of 5 simultaneous touches, with wacky behavior if a sixth touch occurs. Now that people are getting their hands on ipad hardware, has anyone confirmed the actual limitations? There was thought that Apple might relax it to allow for as many as 10 touches, but I haven't seen this confirmed.

    As far as I can tell, the iPad is still limited to five touches. At least as far as game salad is concerned.

    I'm nearly 100% sure that the five touch limit still applies to the iPad.

    Hopefully someone will be able to test the limit on real hardware and will be able to answer definitively without guessing. I'd do it myself, but I won't have a development iPad for at least a few more weeks.

    :confused: Of topic I know, but just how do you manage to use six touches for anything practical on an iPhone?

    I seem to recall reading in some of Apple's docs that the 5 touch limit was just in software though, and that it theoretically could be unlimited touches. It would be a real shame if the five touch limit is still in place for a device as large as the iPad so I'm also curious about this.

    TapTap Revenge multiplayer. When 2 players need to hit 3 notes each at the same time, one of them will probably fail :cool:

    Using Shiny Drum, a free iPad app, I was able to light up 10 of its drum pads using all of my fingers.

    So it's at least 10 points so far, confirmed.

    How silly that it's limited. I'd say 20 atleast. That way 2 people can play

    lol. Actually it's true. just tested it out. When playing when your friend, the trick is to try to do it as soon as possible, while still hitting the note.

    I remember reading a while back that it was still 5 (of course, that was still during speculation), but I'm thinking that I could be wrong because the Plants Vs. Zombies app description says "dig into multi-touch gameplay exclusively on iPad. Play with up to 11 simultaneous touch points and challenge all your fingers!".

    Edit: Whoops, didn't read to the bottom of the thread. Silly me. Never mind. :)

    I was able to play 8 simultaneous notes in Pro Keys as well.

    BoardBox also supports up to 11 simultaneous touches, so that would appear to be the limit.
     
  14. If I remember correctly limitation of 5 touches are for 1 object instance so you can track more touches if you have several touch-places. But that needs testing.

    It's said to be 11 on iPad and 5 on iPhone/iPod. I've seen the touch input taking up to 50% CPU time on first-gen devices so it was probably mainly an artificial limit based on the CPU speed. Correctly detecting the finger center and distinct fingers can be quite complex.

    So far, 10 seems to work, but since I am alone (at the moment) and I don't want to put my toes on my iPad, it stays at 10 :)
