'In addition to causing health problems,' explains Microsoft in the patent, 'the traditional keyboard and mouse interface can be simply inconvenient in certain situations as well. In one instance, a mother with a baby in her arms is unable to easily perform simple tasks, such as checking email, on a computer.' Users of the 'Foot-Based Interface for Interacting With a Computer,' however, will be able to move their feet and step on the floor a la DDR to execute various commands, such as deleting email or scrolling down the screen. Due to the usual foot-dragging on the part of the USPTO, the patent — filed for in 2006 — was essentially obsolete by the time it was issued on Tuesday, a week after Microsoft's Kinect launch.
