Challenges of controlling the rotation of virtual objects with variable grip using force-feedback gloves

This paper investigates an interaction technique that replicates variable grip strength when using force-feedback gloves in VR. Finger pressure maps to the virtual object's rotational freedom: a firm grip fixes the object's orientation, while a loose grip allows free rotation. A user study (N=21) revealed challenges in controlling object rotation using this technique with the SenseGlove DK1. Despite high action fidelity, grip variability led to poorer performance and increased task load compared to fixed rotation. The authors attribute this to low haptic fidelity, with only kinesthetic forces rendered, lacking cutaneous cues. The paper discusses system limitations and suggests improvements for future haptic interfaces.
