A low-cost 3 projector display system for pain reduction and improved patient recovery times

Medical procedures are often associated with discomfort, pain and anxiety. Previous studies have shown that one way to reduce pain during treatment is to watch nature scenes and listen to nature sounds or escape into immersive virtual environments. This not only benefits the patients' well-being but also effectively reduces costs for governments, health care providers and patients themselves. Previous studies show that high levels of immersion into virtual environments significantly reduce pain that is experienced during medical procedures. However, large-scale immersive display systems are inherently expensive and pixel resolution and field of view in smaller and more affordable Head-Mounted Displays has increased only very slowly over the past 40 years. In this paper we consider a Low-Cost 3 Projector Display System as an alternative display method for restorative virtual environments until high quality, highly immersive Head-Mounted Displays have been developed and are available at a reasonable price.
