Abstract_ Background Hemispatial neglect is a cognitive disorder defined as a lack of attention for stimuli contra-lateral to the brain lesion. The assessment is traditionally done with basic pencil and paper tests and the rehabilitation programs are generally not well adapted. We propose a virtual reality system featuring an eye-tracking device for a better characterization of the neglect that will lead to new rehabilitation techniques. Methods This paper presents a comparison of eye-gaze patterns of healthy subjects patients and healthy simulated patients on a virtual line bisection test. The task was also executed with a reduced visual field condition hoping that fewer stimuli would limit the neglect. Results We found that patients and healthy simulated patients had similar eye-gaze patterns. However while the reduced visual field condition had no .
