    Experiment Description

    Research Overview

    • The major objectives of this research are to verify the system performance of the JAXA-developed Head-Mounted Display (HMD) and to ensure that our HMD does not induce any stress in astronaut musculoskeletal systems or visual systems in a microgravity environment.

    • The HMD system performance in a 1G environment has been verified, but no data is available to confirm that the HMD exhibits the same performance in a microgravity environment.

    • The posture of an astronaut in microgravity is quite different from that in 1G. Furthermore, much evidence suggests that head, neck and eye position of those wearing the HMD are causal factors of stress to their musculoskeletal system and visual system in experiments on the ground. Therefore, we need to determine if the HMD induces any stress in astronauts in microgravity before we employ the HMD practically on ISS.


    To demonstrate performance of HMD System. Wearing the HMD, crew can see electronic documents or movies.

    Earth Applications

    The place is not chosen when it is necessary, and tonal information and the visual information (textual information, still picture, and animation) can be presented selectively by "Hands-Free". Be it to small, to light, not to use both hands, and a function characteristic very effective on the work improving to be able to operate it.
