This article aims to create automatic placement and trajectory generation for the head and the eyes of a virtual mannequin. This feature allows the engineer using off-line programming software of mannequin to quickly verify the usability and accessibility of a visual task. An inverse kinematic model is developed taking into account the joint limits of the neck and the eyes as well as interference between the field of view and the environmental objects. This model uses the kinematic redundancy mechanism: the head and eyes. The resolution algorithm is presented in a planar case for educational reasons and in a spatial case.
