Digital Human Modeling tools simulate a task performed by a human in a virtual environment and provide useful indicators for ergonomic, universal design and represen- tation of product in situation. The latest developments in this field are in terms of appearance, behaviour and movement. With the considerable increase of power com- puters,some of these programs incorporate a number of key details that make the result closer and closer to a real situation. With the differences in terms of performance, qualities, limitations, the choice of the tool becomes com- plicated in this wide range of possibilities. In this context, we propose to study and compare the most human mod- elling software available on the market, and thus provide an aided decision tool to help the designer to get the most adaptable tool.
