HapticLever: Kinematic Force Feedback using a 3D Pantograph

TL;DR

HapticLever introduces a mechanical 3D pantograph system for VR haptics that provides stiff force feedback on virtual surfaces without power consumption, enabling realistic interaction with large-scale virtual objects.

Contribution

It presents a novel kinematic haptic approach using a 3D pantograph that renders large surfaces with small proxies, reducing power use and increasing realism.

Findings

Provides stiff force feedback on static virtual surfaces

Allows free arm movement in virtual space

Uses no power to render forces

Abstract

HapticLever is a new kinematic approach for VR haptics which uses a 3D pantograph to stiffly render large-scale surfaces using small-scale proxies. The HapticLever approach does not consume power to render forces, but rather puts a mechanical constraint on the end effector using a small-scale proxy surface. The HapticLever approach provides stiff force feedback when the user interacts with a static virtual surface, but allows the user to move their arm freely when moving through free virtual space. We present the problem space, the related work, and the HapticLever design approach.
