4. Starting Off  Getting Situated Email, Computer, Phone NDC SATERN log in Etc.  Online Training BCiWeb, SATERN, CITI Basic/Refresher course  Reviewed background materials SHFE Hab evidence report Extravehicular Activity (EVA) CONSUMABLES REPORT 30 July 2012 4

5. Habitability DRP – NEEMO Study results  Supervisor: Sherry Thaxton  Human Factors & Habitability Assessment Tool Transcribed audio and video reports from underwater habitat Took notes and observations from reports Reports were evaluating tools that enable crewmembers to record human factors and habitability observations near real-time -iSHORT (Space Habitability Observation Reporting Tool) -Looxcie -iPad 30 July 2012 5

6. Net Habitable Volume Summer Workshop - Deliverables  Assisted in the development/organization of a spreadsheet of NHV driving tasks from various resources EX: Exercise activities, nominal ingress/egress, suit donning/doffing, food prep, etc. Consolidates list of expected mission tasks from various studies and guidelines Captures additional key information – e.g., does it need a dedicated space?  Assisted in the development/organization of a metrics list Consolidates metrics/methods used in previous studies that may be useful in assessing whether a volume is adequate Captures 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 volume Provides high-level process flow chart, annotated with details related to the process, based on existing process documents Adds emphasis to long-duration mission concerns Adds emphasis to necessary inputs such as ConOps details or assumptions 30 July 2012 6

7. NHV Workshop (07/30/12 – 07/31/12)  Assisted in coordination of workshop  Took notes and audio recording of NHV splinter group  Incorporated additional feedback from workshop into deliverables  Drafted outbrief PowerPoint presentation 30 July 2012 7

8. Displays & Controls Interface DRP  Supervisor: Aniko Sandor  Developed a conceptual prototype for new Extravehicular activity (EVA) suit display Goal: 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 task Suit status data (suit pressure, suit temp, fan speed, etc.) Communication status Crew member (“Buddy”) consumables status Caution & Warning (C&W) messages Table of Contents for procedures Electronic procedures 30 July 2012 8

9. EVA Consumables Display Prototype  First 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. 30 July 2012 9

10. EVA Consumables Display Prototype  Second iteration based on feedback from HFE on the Displays & Controls Interface team throughout several group meetings Formatting changes Additional information added Table of Contents page added 30 July 2012 10

11. EVA Consumables Display Prototype 30 July 2012 11  Electronic Procedures page (eProc) with two viewing configurations: Default “Task” view (left) “Figure” view (right)

12. EVA Consumables Display Prototype  Two alternative layouts developed (Left) consumables data displayed in squares, status information in right column (Right) consumables data displayed in columns 30 July 2012 12

13. Discussions With Subject Matter Experts  Discussions with Subject Matter Experts Met with five Subject Matter Experts to get feedback on the displays Discussion sessions lasted approximately 1 hour, held in the Usability lab Discussed information included, organization of the information and grouping of information  Recommendations included: Grouping oxygen, carbon dioxide and metabolic rate Include “Mission time” Map with location of habitat and crew members Present 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) 30 July 2012 13

14. Iterated Prototype Based on Feedback 30 July 2012 14

15. Displays & Controls Interfaces DRP – Next Steps  Integrate prototype with Legaci metabolic rate advisor Provide realistic consumables data for EVA  Collaborate with Glenn Research Center (GRC) to evaluate prototype on various hardware displays Head mounted display Cuff display  Conduct studies to examine different control methods Touch Voice Cursor control  Continue iterations of design based on future studies 30 July 2012 15

16. Multidimensional icon study  Supervisor: Aniko Sandor  Team members: Shelby Thompson, Ron Archer, John Pace  Assisted in development of Multidimensional icon study  Ran 28 participants in study Goal: Investigate effectiveness of different representations of EVA consumables data for a team of four crew members  Next step: Data analysis 30 July 2012 16
