摘要：A user of a modeling application uses a haptic interface device in the real world

to manipulate a virtual tool in a virtual environment to interact with a virtual object. Theuser can use the tool to evaluate the shape of the virtual object and navigate its virtualsurface, based on an interactive force feedback approach. When the user attempts topenetrate the virtual object with the virtual tool, a modeling application limits themovement of the virtual tool depending on the geometry of the surface, the position ofthe virtual tool, and a haptic interface location in the virtual environment, which

represents the physical location of the haptic interface device in the real world. The usercan evaluate different geometries of the virtual surface, including an edge geometry,such as occurs when the virtual tool is touching or moving along an edge of the virtualobject.
