Looks like multiple touches on the screen? How is the order of touches to screen is known?

If you have a time series of these you can look at the rate of change of the size of the blobs and estimate if the touch is growing or shrinking, but I think this is an example of 4 fingers on the screen at once for multi-touch gestures. They probably sample fast enough that the order of the fingers does not matter for any given sample.
