During human exploration of space, a suited crewmember needs effective and accurate information about their spacesuit's operation. Ideally, the information should be presented in a manner that provides real-time situational awareness and increases task efficiency and operational autonomy. Typically, however, the effective display of information has been limited by the relatively low resolution of radiation-tolerant sunlight readable displays and the low processing power available on currently deployed spacesuits. As part of NASA's Enabling Technology Development and Demonstrations Program, a prototype EVA Information System has been constructed to test and study humancomputer interaction and system operations. In one tested configuration, the Information System provides acquisition and display of science data via a cuff-mounted graphical display and keypad and features a camera capable of capturing both still images and high-definition video. The Information System provides a capability for astronautcomputer interaction beyond currently deployed state-of-the art EVA systems. Using the Information System, crewmembers may receive timeline-based procedures, general procedures, and text messages from either ground or space-based EVA mission controllers. Additionally, using the EVA Information System prototype, crewmembers can generate and analyze scientific artifacts (pictures, videos, or voice notes) and deliver them to the ground-based science team for detailed analysis. This paper discusses the software architecture of the prototype Information System software and the user feedback obtained from field testing the system at NASA's Desert Research and Technologies Studies (Desert RATS) activity.
