About

Kohei Arai is a researcher whose work sits at the intersection of robotics, human-computer interaction, and assistive technology. His primary research areas include neural network applications for robotic control, eye-based human-computer interaction (HCI), and assistive systems for individuals with disabilities. Arai’s most significant contribution is his pioneering work on eye-controlled robotic systems, designed to empower patients with limited mobility—particularly stroke survivors—to regain independence. His 2013 paper on an eye-based domestic helper robot, which allows patients to be self-sufficient and communicate remotely, exemplifies this focus. He has also developed a meal aid system where a robot arm is controlled solely by eye movements, enabling disabled individuals to select and retrieve food. In the domain of robotics, Arai applied Bayesian regularization backpropagation in neural networks to solve inverse kinematics for planar manipulators, a foundational contribution to robotic arm control. While his citation counts are modest—his most cited work has 14 citations—the practical, human-centered nature of his research underscores its potential for real-world impact in rehabilitation and assistive robotics.
