Exploring Users Pointing Performance on Large Displays with Different Curvatures in Virtual Reality

Area of Science:

• Human-Computer Interaction
• Virtual Reality Systems
• Display Technology

Background:

• Large curved displays are increasingly used in Virtual Reality (VR) for immersive high-resolution content visualization.
• While offering a wide field of view and immersion, user performance on these displays is not well understood.

Purpose of the Study:

• To investigate user pointing performance on large virtual curved displays.
• To analyze the impact of display curvature and pointing factors on speed and accuracy.

Main Methods:

• Evaluated pointing performance using standard factors (target width, amplitude) and curvature-related factors (linear and angular measures).
• Compared performance across different display curvatures and with flat displays.

Main Results:

• Reduced display curvature led to improved pointing speed (movement time).
• Display curvature significantly influenced error rates for both linear and angular pointing tasks.
• Throughput analysis indicated curved displays performed similarly to or better than flat displays.

Conclusions:

• User pointing performance on large VR curved displays is sensitive to curvature, with less curvature generally yielding better results.
• Findings provide practical recommendations for optimizing pointing tasks on curved VR displays.
