There are a few companies out there that have spent big money researching and developing high tech personal mobility devices for geeks who don’t want to move under their own power. The most notable of the high tech mobility devices is probably the Segway your local Paul Blart rides around.
Honda has announced its own personal mobility device called the U3-X. The device looks like a high tech unicycle and fits between the user's legs and is controlled by leaning in the direction the rider wants to move.
Honda says the U3-X can move in any direction including to the side and diagonally when the rider shifts body weight. It's not clear form looking at the press release if the U3-X balances itself like the Segway or if the rider is responsible for balance like a bike. The U3-X will be shown at the Tokyo Motor Show 2009.
