At the upcoming SXSW Conference... Honda will give attendees a chance to try out a new mobility device... specifically designed for mixed reality entertainment experiences.
Users can steer... without the use of their hands — they simply have to lean into one direction to move forwards, backwards, sideways or diagonally.
There's no good reason to walk while wearing an AR headset. You might get exercise. If you bump into someone, you might get hurt.
It's so much better to ride around wearing an AR headset instead. If someone bumps into you, you have the opportunity to draw blood. And you just got a great deal on liability insurance! Also, there's no chance it will run out of power and you'll have to push or carry it back to the car.
This would be a great idea for wheelchair users, since I imagine being in a crowd of people at waist level detracts a bit from the experience you'd get by walking. But if everyone is able to use these chairs, it'll just cause more congestion.
