About

Shota Yamada is a researcher focused on human factors and ergonomics, particularly in the context of educational technology. His work centers on the design and evaluation of telepresence robot systems to support school education for students who are long-term hospitalized or chronically absent. In his most-cited study, Yamada investigated the physical ergonomic challenges faced by students using telepresence robots in real classroom settings. By collecting head and neck angles, gaze direction, and viewing distance data from six participants—including healthy middle school students and a hospitalized high school student—he identified significant differences in head flexion angles across educational activities. Notably, during lecture-style classes, students exhibited a mean head flexion angle of −20.4°, which was significantly deeper than during exercise-based classes (−4.7°) or breaks (−12.3°). This finding highlights critical ergonomic risks, such as increased cervical spine strain, that may arise from prolonged use of telepresence robots in educational settings. Yamada’s research provides actionable insights for improving the design of telepresence systems to better accommodate the physical well-being of students, contributing to the broader goal of inclusive and accessible education.
