Gaze Direction Visualization Techniques for Collaborative Wide-Area Model-Free Augmented Reality

Explore innovative gaze direction visualization techniques for collaborative wide-area model-free augmented reality in this 24-minute conference talk from the ACM Symposium on Spatial User Interaction 2019. Delve into the challenges of conveying gaze information in large-scale AR environments without environmental models. Examine two novel techniques: the Double Ray method for reducing visual ambiguity and the Parallel Bars approach for providing spatial cues. Learn about the controlled experiment conducted to evaluate these techniques in target identification tasks of varying difficulty. Gain insights into the effectiveness of the Double Ray technique in reducing visual ambiguity and the limitations of the Parallel Bars method. Discover the implications of these findings for designing collaborative mobile AR systems in expansive outdoor settings, covering topics such as awareness information, laser pointers, experiment design, and result analysis.
