ABSTRACT

Hands-free interfaces could be the best choice for Human-Computer Interaction (HCI) for people with physical disabilities that are not capable of using traditional input devices. Once a first prototype is developed in the laboratory taking into account design and usability requirements, real users is what finally categorize an interface as useful or not. Therefore, an evaluation of our interface with users with cerebral palsy and multiple sclerosis has been carried out during a project of 9 months long. This paper presents a vision-based user interface designed to achieve computer accessibility together with the validation and evaluation of its human computer interaction issues such as usability and accessibility.
