PlaygroundVR is a virtual playground. Through putting on a pair of VR glasses, sick children enter a world where they can play freely. Children that are confined to a hospital bed can experience just being a child. They can even interact with other children in a department in the VR-environment and thus increase their social skills. Playing is important for children, because it is a way to process impressions. Precisely for children that are being treated for an illness, this is essential. Thus PlaygroundVR contributes to both the mental and physical recovery of the child. Research even shows that children experience less pain during unpleasant physical treatments.
