The 40-inch SUR40, co-created by Samsung and Microsoft, is a thin tabletop computer that sees and responds to whatever is placed on it. Each of the table's LCD pixels emits an infrared beam that reflects off an object back to a sensor. The processor synthesises the sensor data to create an eight-bit image from which it can pick out shapes and large text, such as product names and numbers. Once the object is identified, the table displays related YouTube videos and other product information. Right now most apps are on the simpler side, but developers are free to program custom games and more, depending on what bar or store the table winds up in. US$8,400
