My room mate Szabolcs (its
pronounced Sabolsh) works on some haptics stuff. He wanted me to be a test subject for one of his experiments. There was a chair mounted on a platform which can move sideways. The chair had a joystick attached to it at the right armrest, and the idea was to accurately control something using the joystick (in this case, a cursor on a computer screen), when the chair was shaking randomly. Apparently, with no haptic feedback, the control accuracy was poor, and with some feedback to the joystick (similar to the jerk you get on game controllers when you hit something or get shot in a video game), the control accuracy improved. I don't know by how much, but I had fun being a test subject, sitting on a violently shaking chair. I got scared a bit the first time the platform jerked abrubtly to one side. I had a good time..
