Digital remote-action environment for disabled persons: automatic adaptation of the scrolling time to the user's characteristics and intentions

This article deals with a method of automatic adaptation of the scrolling time of the different actions proposed in a man/machine interface called "communicator". The EDITH project (for Digital Remote-action Environment for Disabled persons), elaborated at the University of Metz, was used as a test-bed to define this method. It is only after the clinical evaluation of the EDITH system with a patient suffering amyotrophic lateral sclerosis that we realized an optimization of the temporal management on the control sensor that enables to increase the performance of this type of interface.
