Web accessibility recommendations for the design of tourism websites for people with autism spectrum disorders

The universal Web design represents an ambitious and open challenge for the current research on the Web. Key aspects are Web accessibility and Web usability by people with the widest possible range of abilities, operating within the widest possible range of situations. Universal design is adaptive for the users, and provides personalised answers to different users. A recent study shows an estimation of the global burden of people with Autism Spectrum Disorders. In the last 24 years, the incidence of autism has a stable prevalence of 7.6 per 1000 or one in 132 persons. They represent a significant number of people.

The second website contains as a tourist destination the area around Mestre, close to Venice, Italy. In this case, the website has been validated on a single, non-verbal autistic user
