Toyota Prius: the gear ... Huh? Like a joystick

I was at the IGEM 2012 show yesterday at the KLCC, the show case of the green technology & innovation. Kind of exciting & cool to see the new stuff display and demonstrate.

One of the thing that I want to share is the Toyota Prius gear stick.. It is really like a joystick.. Really fun to see it.

The gear just have three main functions.. Which I am not so sure what is it mean. I believe it should have the drive, reverse, parking minimum.. Similar to the our current automatic gears..

For your eyes & analysis, here I attached the picture of the gear.. Enjoy..
