Handrails 2.0 ?

My dad's 'fall down go boom' experience has me pondering if, when we go to make improvements around here the next time, it might work to set up a series of hand rails that are strategically placed and bolted to the floor. It would be kind of like them little lead things in banks and airports where you have a hand rail that guides the person from point A to point B but would have breaks in it so that you can go off the guide path if you want/need to. I need to get out a floor plan for the house and look at if that is something that is feasible.
