We've seen some interesting large-scale multitouch products from SMART lately, but the company's bread and butter is still the SMART Board interactive whiteboard, and it's getting a neat little upgrade today: touch recognition. The board now intelligently senses the difference between a pen and your hand, so you can draw with the pen, move objects with your finger, and erase with the palm of your hand all at the same time -- no tool switching required. It's just a little tweak, sure, but it's the stuff like this that's going to make touch a viable primary interface -- check out a video after the break.
