An exhibition collecting numerous handheld devices used in the pavilions of Expo 2025 Osaka-Kansai. The handheld devices introduced a system that automatically linked commentary audio, video, light, and vibration effects according to visitors' location information, heart rate data, and actions to exhibits, realizing rich learning experiences tailored to each individual even in large-scale spaces where thousands of people visit daily, like Expo pavilions. In this exhibition, based on devices collected by the science museum as Expo legacy, including loaned materials, the new exhibition styles pioneered by Expo are reviewed through valuable actual materials from 13 pavilions and zones with various shapes and functions.
