Unilateral spatial neglect (USN) is a highly-prevalent neuropsychological syndrome following a cerebral stroke characterized by massive impairments in daily life. The evaluation and the rehabilitation of USN encounter many limits whereas immersive virtual reality (VR) could be an efficient tool to go through these limits by imitating an environment of perception and action very close to the real one. The investigators will test a multisensory battery of evaluation based on VR for the diagnostic of USN.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Spatial cognition assessment | Experimental | A single session of spatial cognition assessment (baseline) will be proposed to participants. This assessment will be based on paper-and-pencil tasks and immersive virtual reality tasks (with an HTC Vive Pro Head-Mounted-Display). The assessment will last around 1 hour. |

| Spatial cognition assessment | Behavioral | The intervention will be composed of tasks assessing spatial cognition in a real environment (cancellation task, line bisection and baking tray task) and in a virtual environment (cancellation task, line bisection, baking tray task and localization tasks).The Catherine Bergego Scale (questionnaire) will also be used. |
| Measure | Description | Time Frame |
|---|---|---|
| Omissions in cancellation tasks | Number and localization in space | Baseline |
| Deviation in line bisection tasks | Deviation of the bisection from the true center of the lines (in mm) | Baseline |
| Number of the cubes in each side of space in the Baking Tray Tasks | 16 cubes have to be disposed | Baseline |
| Detections in the localization tasks | Number and localization in space | Baseline |
| Measure | Description | Time Frame |
|---|---|---|
| Duration of eye fixation in each side of space during VR tasks | Collected thanks to the VR headset | Baseline |
| Completion time of each task | (in s) |
