Microsoft recently unveiled their Microsoft Surface Computing technology that they have been demoing and perfecting over the past six years or so. It looks like this is a great idea that will unlikely to take off any time soon. I would love to see it used for many of the scenarios they present such as syncing to cell phones, paying with plastic by dragging bill items to your card that has been placed on the table, or having a video puzzle which shows the potential of the technology. They would most definitely make this into a platform technology as well, sort of like the tablet where applications can utilize all the different functionality that is available.
This is similar to Jeff Han’s Perceptive Pixel’s touch screen technology. He showed off his research at the TED conference a few years back, but this technology is different from Microsoft’s. I’ll go into details in another post.
