Autism Spectrum Disorder (ASD) is defined as a neurodevelopmental disorder that affects the functioning and development of social communication (DSM5 - 2013). ASD causes particularities in sensory treatments (auditory, visual), qualified as uni-modal. Added to this, there is difficulties to deal with prevailing stimuli of the environment (pluri-modal) ; parents report the discomfort of their child in this situation with "noisy" behavioral manifestations. Therapeutic social skills programs most often address the subject's lack of adjustment to their environment through understanding social rules and codes and cognitive treatment of situations. Thus, in order to relieve the sensory modulation disorders which can be the cause of social adjustment difficulties, it's propose to exercise the sensory habituation of children with ASD thanks to virtual reality scenarios restored in 3D immersion booth (the CAVE). The child will be exposed to multimodal stimulation during immersion sessions reproducing the conditions of an ecological environment. A therapist will accompany the child in the CAVE throughout the session. The investigators hypothesize that regular and repeated exposure to a simulated environment in the CAVE can improve multisensory treatment capacities and have a beneficial effect on the autonomy of children and adolescents with ASD in everyday situations.

Behavioral scale VABS II is a test for assessing autonomy of child/adolescent in everyday life. From 0 to 108, higher is the score, more independent the person is in the rated field.

ECA2 provides an assessment of the current extent of the child's behavioral characteristics. Scale reportes a score from 0 to 4, 5 levels according to the current importance of these behaviors (0 :absent - 4 :very serious)

ECA2P provides an assessment of the current extent of the child's behavioral characteristics. Scale reportes a score from 0 to 4, 5 levels according to the current importance of these behaviors (0 :absent - 4 :very serious)

Dunn sensory profile is completed by the parents. From 0 to 110, higher is the score more important is the comportement

VABS-II provides an assessment of problematic behaviour. From 0 to 108, higher is the score, more independent the person is in the rated field.

Evaluation of intensity scores for signs of stereotyped and repetitive activity on the EC2R.Factor sensory-motor stereotypies is evaluated by a score from 0 to 44. Factor reaction to change and modulating insufficiency factor are evaluated by a score from 0 to 28. Factor restricted behaviors is evaluated by a score from 0 to 32. Higher is the score more important is the severity.
