Brief Summary

Computers now play an important role in the lives of most individuals.Access to computers is crucial for people with disabilities and may improve their quality of life. The use of computers can facilitate mainstreaming at school, for example, and the Internet may provide a valuable means of communication. However, the use of computers requires a certain degree of motor ability. People with motor disabilities frequently experience difficulties using a standard keyboard and standard pointing input systems such as a mouse. Many solutions exist to facilitate computer access, depending on the person's specific impairments and the purpose for which the computer is used. The most common solution relies on the use of a virtual keyboard which is directly displayed on the computer screen. The selection of the desired key on the virtual keyboard can be handled by a large variety of input devices, from a microgravity mouse to single switch devices supplemented by a process of dynamic scanning of the keyboard.Although such assistive devices render computers accessible to people with disabilities, the actual inputting of text can be very slow. A method to increase text input speed is to display words which are predicted from the letters previously typed. Word prediction reduces the number of necessary key strokes by avoiding having to type the whole word. The effect on text input speed is, however uncertain and results in the literature are inconclusive. Indeed, word prediction software provide a enhancement of cognitive load which decrease text input speed.The reduction of cognitive load could therefore be based in part on the optimization settings of the software and / or achievement of a rehabilitation program.Our hypothesis are for people with spinal cord injury : i) optimization settings word prediction software and ii) a rehabilitation program could improve the text input speed.The investigators propose to study the influence of settings word prediction software on text input speed and the influence of a rehabilitation program provided by a therapist, focused on word prediction software to help integrate them. The aim is to increase the performance of people with spinal cord injury and their satisfaction. The first phase of this research is to select the word prediction software and configuration that provides the best user support.The second phase corresponds to the objective of evaluating the efficiency of a rehabilitation program .
