Martin Frey came up with a concept called CabBoots. It is a completely novel interface for pedestrian guidance applications. The feedback takes place at the body part that is most affected while walking: the foot.Electromechanic parts in the sole of the shoes are able to generate the angle of the shoe as well of the feet artificially. The artificial slope is not distinguishable from a real one. Individual and virtual trails can be communicated by the shoe.
