- Intelligent wheelchair simulator for users' training: Cerebral palsy children's case studyPublication . Faria, Brigida Monica; Reis, Luis Paulo; Teixeira, Sofia Carmo; Faias, Joaquim; Lau, NunoThe use of real context simulation programs for training driving skills to control an intelligent wheelchair is an emergent area. The aim of this study is to verify if the exigency of use of the simulator of the IntellWheels project is adequate to the skills of children with cerebral palsy. A group study case was performed using children with cerebral palsy classified in the levels IV and V of the Gross Motor Function Classification System, aged between 6 and 12 years old. The user's performance in a wheelchair driving game using the Joystick and the Wiimote (for head movements' recognition) and the users' opinions about the system were studied. Results suggest that the system matches the children skills and it was verified that it was easier to drive the wheelchair with the joystick for most of the participants. Generally, the participants presented positive reactions, showing themselves satisfied with the experiment and convicted about the wheelchair future usability.
- Intelligent wheelchair driving: a comparative study of cerebral palsy adults with distinct boccia experiencePublication . Faria, Brígida Mónica; Silva, Ana; Faias, Joaquim; Reis, Luís Paulo; Lau, NunoAn electronic wheelchair facilitates the autonomy and independence of a person, however specific cognitive, sensorial and perceptual skills are needed to conduct the assistive technology. These skills are also inherent to the sport boccia. Thus, the aim of this study is to understand the relationship between the experience of the participant in driving a wheelchair in relation to their autonomy and independence and also examine the practice of boccia in relation to the cognitive skills and performance in driving an intelligent wheelchair using a simulator. It was performed an evaluation of 28 participants, 6 of whom had no experience driving an electronic wheelchair and 22 had experience, 15 practice boccia and 13 did not practice this type of adapted sports. In the collection of data was tested three interfaces command of a smart wheelchair in a simulator. It was showed a good performance of the participants with experience in using electronic wheelchair and practitioners of boccia. It was also possible to observe that the autonomous and independent participants showed good results.
