In the last 10 years there has been a growing experimentation and production of technologies useful to support the learning processes of students with special educational needs (autism, learning disabilities, attention and hyperactivity disorders, severe disabilities). All the technology production of these years has given life to an important number of innovative solutions. These innovation processes made it necessary for software engineers to begin to understand more about the psychological functioning of people with special educational needs. Many observation scales of the psychological functions and behavior of the person with autism have been designed and developed for use in the clinical setting and collect and contain very detailed information that is not necessary for those who have to develop technological systems to support learning processes. For these reasons it is necessary to develop new observation tools that give useful information to software engineers, especially as regards the aspects of sensory-motor coordination, relational aspects, cognitive functions and communication functions.
