Microsoft's Kinect is a motion-sensing device that allows people to control Xbox video games using body movements alone. It consists of a webcam-like camera for creating an image of players, an infrared laser for measuring their distance, and a specialised microchip that interprets the data to track people and objects in three dimensions.
Microsoft's hope in launching the Kinect was to change the way people interact with and play video games. But many users immediately recognised that the device had broader applications and began to hack it for their own projects. Before long, Microsoft released software developer kits allowing anybody to develop applications for the Kinect on both the Xbox and Windows.
Enter David McGloin and buddies at the University of Dundee in Scotland, who are experts in an area of physics called optical manipulation: the use of highly focused laser beams to trap, move, and even rotate small particles such as cells.
