Grabity: A Virtual Reality Controller that Simulates Weight and Stiffness

Stanford researchers in the SHAPE lab have patented a virtual reality, haptic device called 'Grabity' that simulates weight, stiffness, and torque. Grabity uses two linear resonant actuators (LRA) attached adjacent to the fingers to simulate stiffness and buoyancy of virtual objects while grasping. Unlike existing devices, this efficient method provides realistic mass perception making it ideal for virtual and augmented reality and gaming applications.

Stage of Development - Prototype
Inventors have successfully built and demonstrated the prototype device. (See the following video demonstration.)
