Say what you will about Kinect games, but the Kinect remains an impressive piece of affordable technology. Case in point, Toyota included the tech in their latest Smart Insect prototype, an adorable yet technologically advanced vehicle being shown off at this year's CEATEC in Japan.
The vehicle boasts gull-wing doors and motion detection utilizing Microsoft's Kinect. On-board motion sensors can actually recognize the car's owner based on face and body shape, and can actually predict his/her behavior by analyzing movement -- and determine when to open the car door, for instance. Voice recognition has also been applied to basic functions like opening doors and the like, with a speaker on the hood of the vehicle and a "dialogue monitor" on the front and back dash.
Being a prototype and all, it's very unlikely we'll actually see this car on the road, but hey, it's fun to see regardless.
