The process of evaluating the accessibility to manipulation in a built environment is linked to the determination of accessibility in its overall meaning (access, move, use). This amounts to evaluate all the possible movements of an articulated structure taking into account the constraints due to the environment and the mobility device (trolley or wheelchair). It is important to ask the question: how the environment is accessible? Given these assumptions, the process of evaluating the accessibility is formulated as a problem of inverse kinematics of an articulated structure (mobility device and user) by verifying that the end effector (the hand) can reach objects in the environment taking into account the constraints related to the degree of disability and those related to the nature of the environment. The approach is demonstrated on simulated environments using the techniques of virtual reality.
