User Model to Design Adaptable Interfaces for Motor-Impaired Users

User modeling is an important strategy for designing effective user interface. User model for able-bodied user is not always suitable for physically and mentally retarded people. There are some special characteristics of users and also of the interfaces, which have to be considered when building a user model for disabled users. This paper concerns about modeling motor-impaired users for developing personalized interfaces for those people. In the proposed user model, main emphasis is given on making the user model application independent, clustering users according to their physical disability and cognitive level and adapting the model with respect to individual user as well as cluster of users.
