In the envisioned setup, the patient operates in a virtual environment were his avatar interacts with virtual objects. This bidirectional interaction involves motor (e.g. arm/hand movement), sensory (e.g. visual, audio and tactile) and cognitive (e.g. executive function) functions. In this virtual environment, the patient has to solve a task through his avatar, for example, to interpret visual, audio and tactile information to find objects in the non-neglected space and move them into the neglected space. Such a VR based tool can be used to diagnose and quantify USN or to train the "attentional shift" with the goal to achieve a short and long-term reduction of USN.
