Melk Design makes use of exact 3d models to solve Human-Factor-Challenges. This Human 3D model is modeled from laser scanned data, and is very exact. The wheelchair is not designed by Melk Design, but is used during the design process to make sure the concept is adjusted to all potential users. The wheelchair is produced by Handicare The 3d model is the production 3D model from Handicare, and is 100% exact. It is also possible to elevate as in real life. Melk Design also use many other human 3d model that are produced from laser scan. Many of these come from LowPolygon3D.
