Development of Haptic and Force-Feedback Interfaces Using Perceptual Illusions

My research focuses on developing compact and lightweight haptic interfaces that generate diverse tactile and force sensations by exploiting human haptic perception and perceptual illusions. In particular, I investigate force illusions induced by skin shear deformation and vibration, aiming to create sensations of force and movement without applying large physical forces. Through this research, I seek to develop wearable haptic technologies that provide effective force feedback without relying on large mechanical systems.

Human Motion Guidance and Motor Assistance Through Haptic Stimulation

My research investigates techniques for guiding human movements and posture through haptic stimulation. A particular focus is the Hanger Reflex, a phenomenon in which pressure applied to the skin induces involuntary rotational movements of the head or other body parts. I explore methods for eliciting and controlling this phenomenon in different body regions to guide posture and movement. I also develop haptic-based motion guidance and assistance techniques, with potential applications in rehabilitation, navigation, and motor skill training.

Embodied Interaction in Virtual and Extended Reality

My research explores embodied interaction in virtual reality (VR), augmented reality (AR), and other extended reality (XR) environments through haptic and force-feedback technologies. I investigate wearable interfaces for interacting with virtual objects, providing feedback during body movements, and guiding posture and head orientation. By integrating haptic stimulation with visual and auditory information, I aim to enhance immersion and bodily sensations in virtual environments and develop interactive systems for applications such as sports, gaming, and education.
