Anup Chathoth, left, co-founder and CEO of Ubi Interactive, demonstrates his company's system, which can turn any surface into a touch screen, with the help of a colleague at the Microsoft Accelerator for Kinect exhibition in Redmond on Thursday, June 28, 2012. &quot;You can use any surface -- glass, table, whiteboard,&quot; Chathoth said. This is using glass with a film backing, so it looks particularly good. Photo: Aubrey Cohen/seattlepi.com Staff
