Outcome Measures

Primary Outcomes (12)

• Motor Performance - Speed

  We will track and store participant movements during each task via the VR headset. These movements will be downloaded and processed to calculate speed

  Through study completion, 1 day

• Motor Performance - Velocity

  We will track and store participant movements during each task via the VR headset. These movements will be downloaded and processed to calculate velocity

  Through study completion, 1 day

• Motor Performance - Precision

  We will track and store participant movements during each task via the VR headset. These movements will be downloaded and processed to calculate Precision

  Through study completion, 1 day

• Motor Performance - Trajectory

  We will track and store participant movements during each task via the VR headset. These movements will be downloaded and processed to calculate trajectory

  Through study completion, 1 day

• Motor Performance - Path Length

  We will track and store participant movements during each task via the VR headset. These movements will be downloaded and processed to calculate path length

  Through study completion, 1 day

• Motor Performance - Time to Target

  We will track and store participant movements during each task via the VR headset. These movements will be downloaded and processed to calculate Time to target

  Through study completion, 1 day

• Motor Performance - Error rate

  We will track and store participant movements during each task via the VR headset. These movements will be downloaded and processed to calculate error rate

  Through study completion, 1 day

• Embodiment

  Participants perception of immersion during VR experience: Using Peck's Embodiment Scale (16 items scored on a 7 point likert scale with a final score between 1 and 7 with a higher score indicating greater emobidment) and the IPQ Presence questionnaire (14 items on a 7 point likert scale with a higher score indicating greater embodiment)

  Through study completion, 1 day

• Presence

  Participants perception of immersion during VR experience: IPQ Presence questionnaire (14 items on a 7 point likert scale with a score between 7 and 98 and a higher score indicating greater presence)

  Through study completion, 1 day

• Usability - Engagement

  Participants perception of the ease of use of the VR system using the User Engagement Scale (a 12 item 1-5 pt likert scale with scores between 12 and 60 and a higher score indicating greater usability)

  Through study completion, 1 day

• Usability - Task Demands

  Participants perception of the ease of use of the VR system using the NASA Task Index (6-item scored on 10 point VAS. Items are weighted by subject perception of what is important part of task. Higher score indicates greater task demand)

  Through study completion, 1 day

• Usability - ease of use

  Participants perception of the ease of use of the VR system using the System Usability Scale (10 item scored on 1-5 likert, scores are converted to a 100 scale with a higher score indicating greater ease of use)

  Through study completion, 1 day

Study Arms (2)

Visio-tactile stimulation (VTS) during Virtual Reality

EXPERIMENTAL

Participants in this group will receive visio-tactile stimulation prior to engaging with the VR program. They will see their virtual hand touched while simultaneously feel their opposite real hand touched in the same pattern.

Behavioral: Visio-Tactile Stimulation

No Visio-Tactile Stimulation (NoVTS) during Virtual Reality

NO INTERVENTION

Participants in this group will not receive visio-tactile stimulation prior to engaging with the VR program. They will be asked to look at their virtual hands for approximately the same amount of time as the VST group receive their stimulation

Interventions

Visio-Tactile Stimulation BEHAVIORAL

They will see their virtual hand touched while simultaneously feel their opposite real hand touched in the same pattern.
