An Information System prototype for analysis of astronaut/computer interaction during simulated EVA

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 human-computer 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 astronaut-computer 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.
