Study on the level value standard of the robot appearance interface factor for user experience design

Abstract

This study aims to establish the robot's external appearance interface design factor level values, which give meaningful differences in user experience, by clarifying the standards for the level values. The standards of the level values for the core design factors of the external appearance interface were summarized through the reference studies, and level value cases were summarized through case study analysis. Lastly, the existence of meaningful differences from the values derived through the reference studies and case study analysis in terms of user experience were investigated. As a result of the research, it was found that 'prototype categorization, 'visual realization', 'level of body materialization', 'level of body components materialization', 'proportion of body components', 'height compared to user', and 'width compared to user', that are researched as the standards for dividing the level values, show differences in user experience, so they should be utilized as important categorizing factors. When the detailed level values that were divided with above standards do not show a meaningful difference in user experience, they were merged, and among the researched 27 subordinate level values, three level values were deleted and re-summarized into 24 level values. This study has a significance as a base study that systematizes the robot interface design factors in terms of user experience. © 2018 SERSC Australia.
