Guidance of the Center of Pressure Using Haptic Presentation

TL;DR

This paper introduces a haptic feedback system using a Wii Balance Board and vibration motors to guide the Center of Pressure, comparing its effectiveness with visual and auditory cues through experiments and surveys.

Contribution

It presents a novel haptic guidance system for CoP control and compares its performance with traditional feedback methods.

Findings

Haptic feedback effectively guides CoP movement.

The system reduces induction time compared to visual and auditory cues.

User surveys indicate high satisfaction with haptic guidance.

Abstract

Accurately instructing posture and the position of the body's center of gravity is challenging. In this study, we propose a system that utilizes haptic feedback to induce the Center of Pressure (CoP) movement. The Wii Balance Board is employed to sense the CoP, and vibration motors are used for haptic feedback. To provide a comparison, inductions were also performed using visual and auditory feedback, and the time required for induction was measured. Additionally, after the experiments, a questionnaire survey was conducted.
