A 3d Puzzle for Learning Anatomy

We present a new metaphor for learning anatomy the 3d puzzle. With this metaphor students learn anatomic relations by assembling a geometric model themselves. For this purpose, a 3d model is enriched with docking positions which allow objects to be connected together. As complex 3d interactions are required to compose 3d objects, sophisticated 3d visualizationand interaction techniques are included. Among these techniques are shadow generation, 3d input devices, snapping mechanisms and collision detection. The puzzle, similar to a computer game, can be operated at different levels. To simplify the task, a subset of the geometry, e.g. the skeleton, can be correctly assembled initially. Moreover, textual information concerning the region of objects is provided, along with snapping mechanisms to support the user. With this approach we expect to motivate students to explore the spatial relations between parts of the human body.
