Domino tags recognize commands

These are domino tags. They can be placed on top of the Surface device, which then recognizes commands from the pattern of eight dots. The tags can be used on a variety of objects, and different commands can be programmed into the Surface system. Microsoft is developing domino tags with 90 dots to increase the number of options.
