5Net Habitable Volume Summer Workshop - DeliverablesAssisted in the development/organization of a spreadsheet of NHV driving tasks from various resourcesEX: Exercise activities, nominal ingress/egress, suit donning/doffing, food prep, etc.Consolidates list of expected mission tasks from various studies and guidelinesCaptures additional key information e.g., does it need a dedicated space?Assisted in the development/organization of a metrics listConsolidates metrics/methods used in previous studies that may be useful in assessing whether a volume is adequateCaptures information such as appropriateness for use during conceptual design, pros and cons of the method, etc.Assisted in the development of Process Flow for evaluating a habitat/vehicle volumeProvides high-level process flow chart, annotated with details related to the process, based on existing process documentsAdds emphasis to long-duration mission concernsAdds emphasis to necessary inputs such as ConOps details or assumptions

Displays & Controls Interface DRPSupervisor: Aniko SandorDeveloped a conceptual prototype for new Extravehicular activity (EVA) suit displayGoal: Develop visual design to gather feedback on data that should be included on the display with regards to consumables, how the data should be grouped, how the data should be displayed. Focused primarily on consumables data (Oxygen, Battery, Carbon Dioxide & Water), but other important information also considered:EVA time and time on taskSuit status data (suit pressure, suit temp, fan speed, etc.)Communication statusCrew member (Buddy) consumables statusCaution & Warning (C&W) messagesTable of Contents for proceduresElectronic procedures30 July 20128EVA Consumables Display PrototypeFirst prototype developed based on previous studies and reports:NASA. (2009). Orion Program Display Format Standards Document (Baseline, CxP 72242). Houston, Texas: Lyndon B. Johnson Space Center.Sandor, A., Archer, R. D., & Boyer, J. (2011). Extravehicular activity consumables. Houston, TX 77058: NASA, Lyndon B. Johnson Space Center.

Discussions With Subject Matter ExpertsDiscussions with Subject Matter ExpertsMet with five Subject Matter Experts to get feedback on the displaysDiscussion sessions lasted approximately 1 hour, held in the Usability labDiscussed information included, organization of the information and grouping of information

Recommendations included:Grouping oxygen, carbon dioxide and metabolic rateInclude Mission timeMap with location of habitat and crew membersPresent consumables data graphically Distance measures data (i.e. distance from habitat)Type of data displayed should change according to mission ops (e.g., suit port info, rover status info)Include recording status data (Video, Audio, Pictures)
