GamesBond: Bimanual Haptic Illusion of Physically Connected Objects Using Grip Deformation

ACM CHI — Honorable Mention

GamesBond creates a bimanual haptic illusion of two physically connected objects in VR using dynamic grip deformation on 4-DoF controllers without any physical linkage. User studies showed enhanced realism, immersion, and enjoyment.

To give both hands the feeling of holding one object in VR, previous work physically linked two controllers with a mechanism that renders adjustable stiffness. But a physical link restricts movement, can’t be removed for free motion, and can’t keep up with highly dynamic objects with many degrees of freedom — like a jumping rope swung between the hands.

Solution — a “virtual bond” from grip deformation

GamesBond is a pair of 4-DoF controllers with no physical link between them that still create the haptic illusion of a single connected object. Each handle mechanically bends, twists, and stretches; those kinesthetic deformations of the skin make both hands feel one coordinated motion — a virtual bond.

Applications

By rendering different grip deformations, the controllers can simulate a range of immersive two-handed experiences — a jumping rope, the illusion of force, and various rigid grip shapes. A user study showed GamesBond increased the realism, immersion, and enjoyment of bimanual interaction.
