VR Motor Cues: Inducing user movements in virtual rehabilitation systems.

Abstract

Generally, the tracking system is one of the main restrictions in a virtual rehabilitation system because of its cost and / or complex setup. Here we introduce the concept of Virtual Reality Motor Cues (VR Motor Cues). VR Motor Cues include those mechanisms designed with the specific purpose of inducing the user to realize a specific motor activity. An effective VR Motor Cue can guarantee, in a high percentage of cases, the realization of specific user movements, thereby avoiding the need to integrate a tracking system to ensure these movements are carried out. Following this concept, this contribution proposes two initial classifications of VR Motor Cues.
