Abstract: Severe neurological conditions may considerably affect one’s functional capabilities. Special computer interfaces and access methods have been developed in attempt to provide a mean to overcome the functional disabilities experienced by persons in these conditions. In this paper, a case study on the usage of a brain-body interface by a young man with Amyotrophic Lateral Sclerosis is presented. From the study different ways of interacting with the computer, beyond the traditional direct selection and scanning methods, emerge. These resort to control signals that combine binary and continuous features, blended control signals. Such control signals may provide more flexible and efficient ways of interacting with Assistive Technology systems, especially for those individuals with neurodegenerative conditions.
