Design Principles and Strategies of Interface in Extra Vehicular Activity Spacesuit

The purpose of this paper is to reflect on the design method and process of extravehicular activity (EVA) spacesuit interface design, which is mainly dominated by engineering. Studies in the literature focus on “physical device,” but research on “interactive behavior” is insufficient. This study also proposes a change in the design strategy of an EVA spacesuit’s interface from the design of “things” to the design of “behavior”. Interaction design takes people’s “interaction behavior” as its design object, and the interface itself are the intermediary of the interaction process. This paper analyzes the influencing factors and principles of the design of the interface of the spacesuit through case studies and analogy analysis. Results of this study can help designers comprehensively research the relationship among humans, actions, intermediary (tools), goals, and scenes involving the interactive design of a spacesuit.
