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

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

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

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

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

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


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


30 July 2012 11

Electronic Procedures page (eProc) with two viewing configurations:• Default “Task” view (left)• “Figure” view (right)


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

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

Iterated Prototype Based on Feedback

30 July 2012 14

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

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
