Development of a wearable lower limb force feedback device that can move freely in VR space

Abstract

In recent years, force feedback devices have been developed to improve the reality of VR experiences. However, most of the general force feedback devices target the upper limbs. By realizing force feedback to the lower limbs, it will be possible to realize an experience in VR space that cannot be achieved by force feedback to the upper limbs alone. Therefore, the authors aim to develop a lower limb force feedback device. In this study, we developed a lower limb force feedback device based on a physical model at soccer kicking. The output torque of the developed device was confirmed that met the target torque by the experiment.
