Study the feasibility of assisted systems for the disabled taking into account the views of users. Presentation and operating principle of adapted interfaces developed in the research group of the authors. Presentation of the structure and principle of operation of two systems that use the adapted interfaces implemented. The first succeeds in establishing a surveillance and telecare system using a mobile robot equipped with a webcam. The second facilitates patient mobility through the control of a modified electric wheelchair. Presentation of the results and experience in the use of the entire system and interfaces. Additionally there is a discussion about the advantages of the interfaces based on residual voluntary actions of severe motor disabilities and compare its advantages over other systems found in the scientific literature for the same kind of disability. The developed devices are described with sufficient level detail. Thus a specialized reader can incorporate different tools and procedures to their own developments. The comparison that will be made with similar systems will focus primarily on the study and adaptation to the parameters defined in the introduction. In addition it should be noted that the adequacy of systems will be studied in relation to its use in patients with severe motor disabilities excluding other types of disabilities like sensorial or cognitive ones and their specific needs. 3. Implementation This section describes the working principle of a robot guidance system based on a user interface customized according to severe motor disabled patients. This system has been implemented in two different applications the first one a surveillance and telecare system using a mobile robot equipped with a webcam .
