To develop the usability testing criteria of a movement support service robot for elderly people, this study carried out the followings: product selection, selection of target product, IRB passing, development of leading indicators, correction by experts, preliminary evaluation according to the scenario and development of core indicators. For this, a draft questionnaire was developed against the elderly at around age 60. After small group tests and interviews, the experts modified the initial draft to the Usability evaluation Criteria of movement support service robot for elderly people.
