NCT07431970

Brief Summary

The goal of this study is to learn whether virtual reality (VR) construction tasks can detect performance changes associated with prior sleep, and to determine the extent to which these changes can be distinguished from interacting repetitively with VR itself.

Outcome Measures

Primary Outcomes (4)

  • Feasibility: Recruitment

    Number of eligible participants who enroll in the study.

    From first date of recruitment activities to last day of study activities, up to 100 weeks.

  • Feasibility: Retention

    Proportion of eligible participants who enroll and complete all scheduled study visits.

    From start of recruitment activities to the end of study activities, up to 100 weeks.

  • Feasibility: Tolerability of Repeated VR use and Physiologic Monitoring

    Proportion of participants able to complete repeated VR tasks and physiologic monitoring without early discontinuation due to discomfort, cybersickness, or adverse symptoms.

    Assessed each 8-hour in laboratory visit

  • Feasibility: Data Completeness and Quality

    Proportion of planned VR task sessions and physiologic recordings successfully completed with usable data.

    Through study completion, an average of 1 year

Secondary Outcomes (14)

  • Instruction Re-Engagement During VR Tasks

    Assessed during each 8-hour in-laboratory visit.

  • Task Resumption Time Following Disruption

    Assessed during each 8-hour in-laboratory visit.

  • VR Task Completion Time

    Assessed during each 8-hour in-laboratory visit.

  • Movement Efficiency During VR Tasks

    Assessed during each 8-hour in-laboratory visit.

  • Controller Interaction Metrics

    Assessed during each 8-hour in-laboratory visit.

  • +9 more secondary outcomes
