Crossing iVRoad: A VR application for detecting unilateral visuospatial neglect in poststroke patients

This paper presents the immersive virtual reality (VR) application iVRoad for the detection of unilateral visuospatial neglect in right hemisphere poststroke patients. With our immersive VR tool, it is possible to perform realistic road crossing in a safe environment using a head-mounted display (HMD). We present and discuss the virtual environment (VE) for an upcoming study with neglect patients, a broad range of neurological patients and a healthy control group. Our aim is to determine whether extrapersonal neglect can be reliably diagnosed in the chronic phase using VR with the help of various measured values (task completion time, errors, head rotations, eye tracking).
