Practicing UX at NASA

My experiences practicing UX at NASA in an engineering driven organization and thoughts on how to communicate the value of user research, usability, and design to skeptics. In this environment hard numbers, requirements, and acronyms rule the conversation. How do you communicate the value of softer concepts such as user research, usability, and design

Adaptive Problem Solving and Mitigation

This presentation examines how problem solving was done on the NEEMO 22 Mission and whether human autonomy teaming would be able to assist in the type of troubleshooting that was conducted by Mission Control

Lessons Learned from International Space Station Crew Autonomous Scheduling Test

In 2017, our team investigated and evaluated the novel concept of operations of astronaut self-scheduling (rescheduling their own timeline without creating violations) onboard International Space Station (ISS). Five test sessions were completed for this technology demonstration called Crew Autonomous Scheduling Test (CAST). For the first time in a spaceflight operational environment, an ISS crewmember planned, rescheduled, and executed their activities in real-time on a mobile device while abiding by flight and scheduling constraints. This paper discusses the lessons learned from deployment to execution

Ratlose Regierungen?! : Sozial- und Wirtschaftspolitik unter dem Druck der Weltmärkte

Die Globalisierung ist ein uraltes Phänomen – wer will, kann sie sogar aus der Schöpfungsgeschichte des Alten Testaments herauslesen: Mose 1, Kap. 1, Vers. 28: „Und Gott segnete sie [Mann und Frau] und sprach zu ihnen: Seid fruchtbar und mehret euch und füllet die Erde und machet sie euch untertan und herrschet über die Fische im Meer und über die Vögel unter dem Himmel und über das Vieh und über alles Getier, das auf der Erde kriecht. Und Gott sprach: Sehet da, ich habe euch gegeben alle Pflanzen, die Samen bringen auf der ganzen Erde …” Der Druck der Weltmärkte trifft alle Branchen,wenn auch unterschiedlich stark, das heißt aber, keine Branche, aber auch wirklich keine, kann die Hände in den Schoß legen. Die Politik war und ist an diesem Prozess ganz maßgeblich beteiligt,weil sie – aus guten Gründen – durch politisches Wollen die Grenzen zum Weltmarkt aufgestoßen und die Transaktionskosten entscheidend gesenkt hat

Playbook Data Analysis Tool: Collecting Interaction Data from Extremely Remote Users

Typically, user tests for software tools are conducted in person. At NASA, the users may be located at the bottom of the ocean in a pressurized habitat, above the atmosphere in the International Space Station, or in an isolated capsule on a simulated asteroid mission. The Playbook Data Analysis Tool (P-DAT) is a human-computer interaction (HCI) evaluation tool that the NASA Ames HCI Group has developed to record user interactions with Playbook, the group's existing planning-and-execution software application. Once the remotely collected user interaction data makes its way back to Earth, researchers can use P-DAT for in-depth analysis. Since a critical component of the Playbook project is to understand how to develop more intuitive software tools for astronauts to plan in space, P-DAT helps guide us in the development of additional easy-to-use features for Playbook, informing the design of future crew autonomy tools.P-DAT has demonstrated the capability of discreetly capturing usability data in amanner that is transparent to Playbooks end-users. In our experience, P-DAT data hasalready shown its utility, revealing potential usability patterns, helping diagnose softwarebugs, and identifying metrics and events that are pertinent to Playbook usage aswell as spaceflight operations. As we continue to develop this analysis tool, P-DATmay yet provide a method for long-duration, unobtrusive human performance collectionand evaluation for mission controllers back on Earth and researchers investigatingthe effects and mitigations related to future human spaceflight performance

Changes in performance and bio-mathematical model performance predictions during 45 days of sleep restriction in a simulated space mission

Lunar habitation and exploration of space beyond low-Earth orbit will require small crews to live in isolation and confinement while maintaining a high level of performance with limited support from mission control. Astronauts only achieve approximately 6 h of sleep per night, but few studies have linked sleep deficiency in space to performance impairment. We studied crewmembers over 45 days during a simulated space mission that included 5 h of sleep opportunity on weekdays and 8 h of sleep on weekends to characterize changes in performance on the psychomotor vigilance task (PVT) and subjective fatigue ratings. We further evaluated how well bio-mathematical models designed to predict performance changes due to sleep loss compared to objective performance. We studied 20 individuals during five missions and found that objective performance, but not subjective fatigue, declined from the beginning to the end of the mission. We found that bio-mathematical models were able to predict average changes across the mission but were less sensitive at predicting individual-level performance. Our findings suggest that sleep should be prioritized in lunar crews to minimize the potential for performance errors. Bio-mathematical models may be useful for aiding crews in schedule design but not for individual-level fitness-for-duty decisions

Designing for Astronaut-Centric Planning and Scheduling Aids

We have investigated and evaluated a novel concept of operations for human spaceflight: allowing astronauts to manage and schedule their own timeline. In order to evaluate this self-scheduling concept of operations, we have designed, implemented, and field-tested astronaut-centric planning and scheduling aid. Our mobile-based software aid, Playbook, has been used in a variety of Earth analogs as well as onboard the International Space Station. We will demonstrate the unique Playbook features that we have developed based on research findings during field testing that facilitate planning and scheduling in extreme environments
