iMedic: a two-handed immersive medical environment for distributed interactive consultation

Area of Science:

• Medical Informatics
• Virtual Reality
• Human-Computer Interaction

Background:

• Traditional 3D medical systems often lack intuitive interaction methods.
• Tele-consulting and virtual reality (VR) offer potential for remote medical collaboration.

Purpose of the Study:

• To introduce and evaluate the iMedic system, a two-handed immersive 3D medical platform.
• To assess the efficiency of iMedic's interface for 3D tasks and collaborative scenarios.

Main Methods:

• Development of a two-handed immersive and distributed 3D medical system (iMedic).
• Implementation of features including measurement tools, interactive segmentation, non-orthogonal views, and 3D markup.
• Conducting user studies comparing iMedic's performance against mouse and one-handed wand interfaces for 3D object placement and construction.
• Evaluating avatar-to-avatar collaboration versus face-to-face collaboration in iMedic-based scenarios.

Main Results:

• iMedic's two-handed interface demonstrated 4.5-4.7 times faster 3D object placement/construction than a mouse.
• iMedic was 1.3-1.7 times faster than a one-handed wand interface for the same tasks.
• Avatar-to-avatar collaboration within iMedic was more effective than face-to-face collaboration for three specific tasks.

Conclusions:

• The iMedic system provides an intuitive and efficient interface for 3D medical tasks.
• Two-handed interaction in VR significantly enhances performance in 3D manipulation compared to traditional methods.
• Immersive virtual collaboration can be superior to traditional methods for certain medical training and consultation scenarios.
