animators have to move the limbs of the characters they are making for animations by using a computer mouse or stylus. They have to tediously move the limbs into place one key frame at a time.
However,their job could be made much easier as researchers at ETH Zurich in the Interactive Geometry lab have now designed a different way of being able to move virtual characters via 3D joysticks. The joysticks can create shapes and movement inputs.
