Abstract
In Tsubazeriai performed during sword stimulation, a strong force works because the sword is pushed with its own power. Therefore, when trying to present this force sense in a game, it is necessary to present a strong and continuous force. In the field of haptic presentation, various haptics are presented. However, existing methods cannot present a continuous strong force sensation like Tsubazeriai. Therefore, in this study, we aimed to reproduce the state in which the forces antagonized. The elastic force of the spring was used to reproduce this state. In this study, a sword-shaped device was created, and force sensation was presented by the elastic force of a spring attached to the sword-shaped device. Furthermore, an evaluation experiment was performed to see if a strong reaction force like Tsubazeriai could be presented using the developed sword-shaped device. As a result, it was found that using the sword-shaped device, it was possible to present a force sense of the reaction force pushed back from the partner required for Tsubazeriai.
