摘要
针对传统医学可视化仿真系统中交互界面和交互技术的缺点,基于视觉跟踪技术采用实物模型设计和实现了一个基于混合现实界面的下颌运动仿真系统。通过对物理界面元素、虚拟界面元素以及交互隐喻的分析,为混合现实环境下的交互技术建立了一个具有通用性的分类体系。物理与虚拟的界面元素之间通过语义映射将用户的操作从物理世界映射到虚拟空间中,从而为用户提供一种更为直观、自然的交互方式。
Aiming at the disadvantages of user interface and interaction techniques of traditional three-dimensional medical visualization,a simulation system of the jaw motion with mixed reality interface is designed and developed.Based on visual tracking technique,this interface uses several types of physical models as UI elements.Through building appropriate interaction metaphors between physical UI elements and virtual UI elements,a preliminary classification system of interaction techniques in mixed reality is proposed.Thus interaction tasks can be well supported by semantic mapping between physical world and virtual space.And users can interact with virtual objects intuitively and naturally.
