Joysticks are a natural control for VR interfaces — problem being, they mostly only work on desks. The Bottomless Joystick overcomes this limitation by attaching the stick to a counterweight. Connected by a gimbal, the counterweight stays planted downward no matter the angle of the stick. It comes from the Smart Systems Institute at the University of Singapore, who also added two servo motors to replicate various force feedbacks and allow for the adjustment of resistance to better replicate real-world experiences.
