Visualizing motion history for investigating the voluntary movement and cognition of people with severe and multiple disabilities

Abstract

Two case studies were conducted with two children with severe physical and cognitive disabilities in this research, and a computer-vision based technique called Motion History was applied to visualize their movement. By changing the conditions of intervention to the children, the Motion History successfully helped to find their voluntary movement and effective stimuli that attracted their attention. It was concluded that finding the changes of movement is very important for extracting voluntary movement and Motion History is suitable for that purpose. This gives us a greater possibility of evidence-based interaction with people with severe and multiple disabilities. © 2014 Springer International Publishing.
