Description of each model user

Based on the premise that the existence of an "average" standard person representative of all populations is a fallacy, we have attempted to establish a series of user profiles.

These users have a common set of characteristics that differentiate them from other user groups. The benefit of dividing subjects into these groups (while remaining aware of the limitations of the method) is to enable us to make an approach to the peculiarities of the individual person.

Classes are distinguished by their characteristics. We do not take into account the condition or deficiency that has led to the disability, but the operational constraints.
