Between the field workers wearing smart glasses and the supporters’ devices, two things become possible: situation sharing via video and audio as well as remote support for inexperienced workers by supporters’ sending images, manuals, etc. Supporters can remotely support multiple sites, and can achieve significant operational efficiency such as standardization of work quality and reduction of travel costs. Communication between the smart glasses and the supporters’ devices does not go on the Internet at all but is done via a server on the docomo Open Innovation Cloud. It is possible to safely and securely send and receive highly confidential on-site videos of manufacturing, infrastructure, medical, etc., as well as files such as drawings and manuals in a highly secure environment.
