UX-Evaluation: Motion Sickness - 2d

VR surgery simulation and post-operative 2D analysis are currently separated.

Hypothesis

H0: VR surgery with magnification quickly induces motion sickness, necessitating separate 2D PC analysis and preventing VR-based analysis.

UX Evaluation

Participants

• 20 students
• Mixed VR experience levels

Test Conditions

A: Current approach with Valve Index

• 5 surgeries
• analysis in 2d

B: Full VR with Meta Quest

Measurements

• Motion Sickness: SSQ
• Usability: SUS, task completion time, error rate
• Preference: Post-test interview

Success Criteria

Hypothesis confirmed if:

• Significantly higher motion sickness in Condition B (p < 0.05)

• 60% prefer Condition A

• 20% higher error rate in VR analysis

Safety

• Abort if SSQ >40 or FMS >7
• 30-min break between conditions

Expected Outcome

If confirmed: Maintain separated workflow If rejected: Develop integrated VR analysis
