基于实物增强的交互式下颌运动可视化

Interactive Visualization of Jaw Motion Based on Tangible Augmented Reality

利用计算机图形学技术实现交互式下颌运动仿真与可视化具有重要意义。针对传统交互界面的缺点,基于视觉跟踪技术利用牙齿实物模型和标记卡片实现了一种实物增强的三维交互界面,将多种交互任务与交互技术无缝融合在一起,物理空间和数字空间实现同步一致性。实验评估表明,这种交互方式能够让用户更有效地利用已有技能,以自然、直观的方式与虚拟对象进行交互。

Realizing interactive simulation and visualization of the human jaw motion by use of computer graphics is significantly beneficial to the dentistry. Using the physical teeth model and marker cards based on visual tracking technique, a tangible augmented interface for this visualization system was developed. Various interaction tasks and techniques were merged into a uniform interface paradigm. Compared with the traditional interface, this innovative interface seamlessly integrated physical space with virtual space together. A primary informal evaluation indicates that dentists can effectively exploit their existing skills, and interact with virtual objects intuitively and naturally.
