Haptic Dial based on Magnetorheological Fluid Having Bumpy Structure

TL;DR

This paper introduces a novel haptic dial utilizing magnetorheological fluid with a bumpy structure to improve user interaction in virtual environments.

Contribution

It presents a new haptic interface design that increases MRF exposure area for enhanced tactile feedback and demonstrates its effectiveness through a virtual game application.

Findings

Enhanced tactile feedback with increased MRF exposure.

Effective user interaction demonstrated in a virtual game.

Improved performance over traditional haptic dials.

Abstract

We proposed a haptic dial based on magnetorheological fluid (MRF) which enhances performance by increasing the MRF-exposed area through concave shaft and housing structure. We developed a breakout-style game to show that the proposed haptic dial allows users to efficiently interact with virtual objects.
