How to ignore a touch input

Recently discovered that all devices are not created equal for example an iPad can track 11 touch points at the same time, where the Kindle Fire and the NOOK can only do 2 and who knows about all the android phones out there.

Here is my question, an app I am developing requires the user to hold their hand over the screen for a certain logistic purpose which means they would add anywhere from 1 to 4 touchpoints when that happens, well I dont need any of those inputs. I would like to have an area of the screen or an object that when touched kills the touch input so the 2 or more touch events are not in use and I can use them elsewhere.

Its a weird problem but it will make sense when/if the app happens.

I know motorola droidx and droid2 have 2 touch points max.

The Kindle Fire screen is small enough that you're less likely to have parts of your hand resting on the edges. I just did a test, and dragging two things around works well enough, you have to intentionally touch a third point in order to ruin things. So, I guess it's more of a design problem, you would make things big enough to easily drag, and positioned in places that make it less likely to cause extra fingers to touch the screen.

If you really need more touch points at once, then just don't publish it for Nook or Kindle Fire.

Colin I am not trying to have the User control more than 2 events at once. The app requires the User to hold the device by the screen so some of the fingers on the screen are useless to the function of the app however they will take over the two available touchpoints. What my goal is to create a handle mc that knows when its touched to nullify the touchpoint and leave it open for other parts of the screen. I hope I am explaining myself correctly.

I tried another test, where I had the first two touch objects immediately stop their touch drags, and most times I couldn't operate a third object. When it did work it would behave strangely, heading off towards the second of the touch points. Overall, I think you won't be able to do what you want to do.
