Lightbulb [Q] app for people with balance problems?

People who have multiple sclerosis often have vestibular (balance) problems. Since GLASS has both 3d gyroscope and 3d accelerometers, I expect someone has an app that gives audio cues as to whether one is leaning left, right, forward or back. Does anyone know of an app for GLASS that can help the nearly 250,000 US citizens that are thus affected?
