About
Hossein Azari is a researcher in the Department of Computing Science at the University of Alberta, focusing on advanced 3D interaction methods. His work addresses the challenges of transitioning from 2D to stereoscopic 3D environments, particularly through the development of the Stereo 3D Cursor (S3D-Cursor) for precise 3D object manipulation.
- Research Areas: Computer Graphics, Human-Computer Interaction, 3D Visualization, Stereoscopic Displays, Virtual Reality, and 3D User Interfaces.
In his 2010 publication, Azari introduced a novel approach to implementing a stereo 3D mouse cursor, enabling users to interact with 3D objects via disparity control. The study demonstrated the technique’s effectiveness in enhancing depth perception and user satisfaction, validated through experiments with QSplatMV software and user evaluations on tasks like 3D lung model contouring.
The theoretical contributions include mathematical models for stereo cursor accuracy, analysis of depth resolution limitations in stereoscopic systems, and proposed virtual enhancements (e.g., auto-disparity adjustment, target size scaling) to improve performance. Applications span 3D games, medical imaging, and autostereoscopic displays, with future work emphasizing accuracy improvements and advanced UI tools.
