People with intellectual disability (ID) should routinely train themselves to carry out a variety of daily challenging tasks while being supervised by one or more supervisors. Virtual reality (VR) technology enables the simulation of certain learning scenarios that would be risky or difficult to set up or repeatedly replicate in the actual world. This paper introduces a VR simulator created for this aim with the assistance of social educators. The purpose is to use VR to conduct learning exercises with teenagers with ID and assess the extent to which the abilities learned in VR can be transferred to the real world. This project focuses mainly on urban mobility with three types of exercise. A study was conducted with 18 students in five institutions for 7 months. Post-tests were also carried out after 1 month with 11 teenagers. In the end, four teenagers are completely autonomous in their travels: two travel on foot and two travel by public transport. Regarding the impact analysis, the results are stable over time regarding self-reported ease, satisfaction, and fatigability. Finally, the system received valuable feedback from the educators.

Virtual Reality (VR) has three main advantages: allowing safe simulations, experimenting different conditions for the same scenario, and providing the perfect replicability of the scenarios. We present a feasibility study on the use of VR and VR immersive headsets to assist young adults (10-18) with intellectual disabilities in learning new skills. We focused on the scenario of a pedestrian crossing without traffic lights, and we considered several environmental conditions (day/night, weather, kindness of drivers, etc.). Our study is not limited to young people with autism spectrum disorder but takes into account young adults with intellectual disability with an associated disorder. 15 young people participated in the study showing a very good acceptability of immersive headsets and a noticeable learning effect already after a short training session. However, a longer and more extensive study is needed to evaluate the transfer of learning to reality.
