The filing, published in November, 2006 describes "a vehicle which can travel in the front and back direction and which can turn by right and left wheels rotated when a rider riding on a step-board moves the position of rider's balance from the center of a vehicle base."
In other words, Sony envisions a device similar to a Carrom Balance Board — a board atop a cylinder that you try to balance on — except with two or more motorized wheels that you drive by shifting your weight.
The described device — a skating roller board — would power down when not bearing weight, a situation that might occur following a fall, for example.
In September, 2006, Segway, Inc. issued a voluntary recall of its two-wheeled electric scooters for potential malfunction that "can unexpectedly apply reverse torque to the wheels, which can cause a rider to fall." The company said it had received six incident reports possibly attributable to this issue.
President Bush famously fell from a Segway scooter in June, 2003, though the machine's maker blames that tumble on operator error.
Sony appears to have considered such incidents because it also envisions three- and four-wheel versions "to improve stability of the vehicle."
