The HiSaturn Navi unit is a oddball - very cool though - piece of work, but outside of that one rare outstanding example, game platforms haven't seen much success integrating into applications outside of entertainment. This is especially true of things like home appliances, where you need to worry about the cost of your unit versus that of a competitor...doctors might be able to afford equipment with crazy 3D rendering systems built in, but for the average person there's absolutely no use for this capability.
