Description

Initial state of Gap:

Exploration crewmembers will rely heavily on information-rich displays for commanding and monitoring vehicles and habitats during autonomous long-duration missions. They will interact with displays using fine motor skills for pointing, touching, and actuating hardware and software controls. We do not know the impacts of extended microgravity on the cognitive functions and fine motor skills required to interact with computer-based systems. 

Interim steps for getting to the target

  1. Mine available data (Human Performance Database current HRP research from BHP/other elements) and Design Reference Missions (DRMs) to identify tasks/scenarios for which allocation of attention and/or cognitive load may be improper, or where cognitive or fine motor impairment would create a safety issue with respect to interacting with computer-based systems.
  2. Construct a table listing the types and levels of operator attention and cognitive load required for identified tasks, and time/safety critical tasks for which cognitive or fine motor impairment would be hazardous.
  3. Complete directed research on the effects of long-duration microgravity on fine motor skills.Complete directed research on the effects of long-duration microgravity on fine motor skills.
  4. Solicit research to identify the impacts of long-duration missions on operator allocation of attention and cognitive load performance. Solicitation topics will be refined through the Cognitive Scoping task, but may include areas such as: 
    • Multitasking [Standing Review Panel (SRP) recommendation]
    • Task complexity (SRP recommendation)
    • Situation Awareness and shared awareness during collaboration (SRP recommendation)
  5. Review/assess results and determine the need for mitigations
  6. Deliver results to Agency stakeholders, including NASA standards and requirements documents (e.g., NASA-STD-3001, HIDH).  

Research Approach

  1. Collect existing spaceflight performance data relevant to the Attention and Cognition, and Motor skills contributing factors.
  2. Perform research targeted at the effects of long-duration spaceflight on the allocation of attention, cognitive performance, and fine motor performance. 

This gap informs the Risk of Impaired Control of Spacecraft, Associated Systems and Immediate Vehicle Egress Due to Vestibular/Sensorimotor Alterations Associated with Space Flight 

Target for Closure
Quantitative effect sizes for different levels and types of cognitive functions and fine motor skills.
  • Effects will be categorized by the HFACS contributing factors: Allocation of Attention, and Cognitive Overload/Underload, Cognitive Impairment, and Motor skill/coordination or timing, prioritized by effect size.
  • Results may also lead to requirements represented in HCI-05 and Mitigation Gaps HCI-06 and HCI-03
Mappings
