Disclosed is a method of localized immunosuppression which may be used for preventing graft rejection or for preventing tissue destruction due to autoimmune disease. A camera generates a stream of images of the user; a processor detects the presence of the user in the stream of images and applies adaptive transformation mapping to the stream of images captured by the camera to generate modified images that appear to be captured from a different point of view of the camera’s actual point of view. The inflated state may form a particular three dimensional shape configured to protect the user from impact andor provide inverse segregation during an avalanche.
