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.
Problem — mechanical links between controllers are rigid and unremovable
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.
