Presenting the Sense of Effort through Vibration Based on Force Estimated by Inverse Dynamics in Videos

TL;DR

This paper introduces a method to convey the sense of effort in videos by generating vibrations based on estimated forces, enhancing viewer understanding of body movements through tactile feedback.

Contribution

The study proposes a novel approach to represent effort in videos using force-based vibrations, enabling real-time tactile feedback synchronized with video content.

Findings

Vibration intensity correlates with estimated force.

Real-time vibration generation from videos is feasible.

Enhanced viewer perception of effort in videos.

Abstract

We present the sense of effort through vibration to help the video viewer understand how the person in the video moves the body. We suppose sense of effort is related to force, so we generate vibration based on force and present the sense of effort through the vibration. We use perceived intensity to make sense of effort proportional to vibration. In our demonstration, you can experience vibration while watching a video. We can create vibration on the spot, so you can experience vibration made from a video taken on the spot.
