Virtual reality allows to create situations which can be experimented under the control of the user, without risks, in a very flexible way. This allows to develop skills and to have confidence to work in real conditions with real equipment. VR is then widely used as a training and learning tool. More recently, VR has also showed its potential in rehabilitation and therapy fields because it provides users with the ability of repeat their actions several times and to progress at their own pace.

ABSTRACT Virtual reality allows to create situations which can be experimented under the control of the user, without risks, in a very flexible way. This allows to develop skills and to have confidence to work in real conditions with real equipment. VR is then widely used as a training and learning tool. More recently, VR has also showed its potential in rehabilitation and therapy fields because it provides users with the ability of repeat their actions several times and to progress at their own pace. In this communication, we present our work in the development of a wheelchair simulator designed to allow children with multiple disabilities to familiarize themselves with the wheelchair.

VR allows the development of specific skills and to evolve independently VR simulation create a safe learning environment, user can test the consequences of his actions without risk in the real world. With a simulation, it is possible to expand the range of possible situations and to adapt them to different users, capabilities and knowledge[1][2]. In addition, the virtual environment allows to easy and quantitatively assessing the progress of the user and his weaknesses [3].

The objective of the current work we present in this article is the realization of an electric wheelchair simulator for children with multiple disabilities, aged between 13 and 16 years. This simulator will prepare children to wheelchair driving, taking into account motor and cognitive aspects. The first stage of this work concerns the development of a demonstrator to assess children’s interest in the IT tool, which will then be integrated into their learning project.

“Multiples disabilities” is a serious handicap associating motor impairment and severe mental retardation, resulting in a extreme restriction of autonomy and possibilities of perception, expression and relationship [4]. In fact, drive autonomously a wheelchair provides better mental and motor development by initiating new movements and by increasing socialization. But learning to drive a wheelchair in real conditions can be dangerous and tiresome sometimes even scary for patients, which can lead to slow this crucial stage in their development. The use of a virtual environment can help in this learning process and also allow them to use an electric wheelchair earlier, once children habituate and control the emotions provoked by driving.
In addition, the handling of the vehicle is not intuitive and requires practice, especially for patients with severe motor dysfunction preventing them from using conventional devices such as the joystick. A simulator may help find which devices are suitable for the individual and teach him how to use it without taking any risk.
This project is carried out in collaboration between the Institute for Children and Adolescents with multiple disabilities Coste Rousse located in Prades-le-Lez (Hérault, France) and the Laboratory of Informatics, Robotics and Microelectronics of Montpellier (LIRMM) in Montpellier. We work closely with the multidisciplinary team (educators, orthoptist, physiotherapist) of the center to make the simulator accessible from this conception. 2 RELATED WORK Several wheelchair simulators are available; some designed to learn to drive or to evaluate the wheelchair and others to understand the difficulties of using a wheelchair and evaluate constructions accessibility. But there is not, to our knowledge, a simulator designed or adaptable for children with multiple disabilities. Marchal-Crespo presents in [5] a wheelchair prototype to facilitate the learning to drive, especially for the mentally handicapped. The system provides a chair with force feedback joystick and sensors to detect collisions. The prototype is able to avoid the walls and other obstacles to help movement.

In the work of Steyn[6], the simulator uses a immersive virtual reality interface displayed on 4 screens and a physical platform with a force feedback chair. ACCESSIM [7] uses a very realistic representation of urban areas to educate architects and decision makers on the difficul
