Hi, sorry for the confusing title.
For example I have a 16x16 2D matrix. and I've pressed on a multitouch pad around (4,4) with a certain force, then the data in the (4,4) slot will be 1. And the slots around (4,4) - 8 of them - will have a number a bit lower (like 0.8). and the slots a step further away - 16 of them - will be lower again (e.g. 0.5).
And in this process, I can use my force to control how much the date would be in the slots.
Here in attachment I've made a simple drawing shows what I mean, there are 2 presses, the top-left is harder than the lower-right.
Edit: the top attachment is the right one, how do I delete posted attachments?
