Rehabilitation robots are frequently used in combination with virtual or augmented reality applications. Impairments in the patient’s visuospatial perception reduces the ability to correctly estimate the distance between virtual objects, leading to a limited task performance. However, the implementation of monocular cues can enhance the performance in patients with impaired visual spatial perception. Since impairments in visuospatial perception are present after stroke, these findings might be crucial when applying virtual or augmented reality-based intervention methods. In order to maximize the therapy outcome, the design of the AR games should be adapted to patients’ visuospatial perception.
