Interactive Virtual Fishing with Rendering Continuous Reel Weight and Line Slack

This paper presents an interactive virtual fishing system that offers continuous reel weight and line slack using a fishing rod-type device and a grounded device. We detect the rotation of the reel and the pulling force of the fishing rod with a current sensor from a hand-crank generator and a load cell, respectively. To render the reel weight, we leveraged a phenomenon of the resistive rotational force change due to the electrical resistance of a hand-crank generator. Also, our system provided the slack of the fishing line by the electromagnets connected to the grounded device. We demonstrate a tug-of-war game between an angler and a fish using our technology. The angler uses our system to catch the fish; the fish escapes from the angler by moving their legs.
