Food for thought!
Could their be a link between this patent and something similar to Perceptive Pixel multi-touch software which Apple already uses in the iphone.
Although patent doesn't refer to such, since when did Apple release patents which stated clearly their intended use.
With a BIG increase in Research and Development over the past 8 Months maybe this is the next big thing that's due.
May sound far fetched but read between the lines and it's not impossible that this is what it could be referring to.
