Research

This research explores how haptic feedback can improve safe human–robot interaction in remote and uncertain environments. By converting environmental information, such as the distance between a robot and nearby obstacles, into intuitive force cues, the operator can perceive risks not only through vision but also through touch. This approach enhances situational awareness and supports safer, more reliable control, especially when visual information is limited. The goal is to develop human-centered teleoperation technologies for applications such as assistive robotics, rehabilitation support, and safe robotic operation in complex environments. 

Mechanical vibration stimulation offers a unique way to influence both human movement and the feeling of movement. When vibration is applied to specific muscles, it can produce actual muscle responses and joint motion, while also creating an illusory sensation of movement. Based on these effects, vibration-based methods are being developed for the safe and noninvasive control of motion and motion perception. These technologies have potential applications in rehabilitation training, tremor suppression, and motion assistance for people with motor impairments.
