he Siena system contains information relevant for moving around the city and descriptions of possible sites of interest (including their accessibility). It is supposed to be used by tourists and citizens of Siena. The system can also support professionals (tourist office clerks) to help people with disabilities in programming their visit to Siena.

The user trial in Siena addressed the information and interaction needs of able-bodied and motor impaired people, accessing the system from their home/office or using public information points. The scenario based evaluation has been organised in three experiments, involving, respectively 24 users (14 able-bodied and 10 disabled), 24 users (again 14 able bodied and 10 disabled) and 12 users (8 able bodied and 4 disabled). The third session has been mainly devoted to adaptivity testing.
