We present Mechanical Force Redistribution (MFR) Floor Tiles: a method of sensing which creates a seamless, anti-aliased image of forces applied to a floor. This technique mechanically focuses the force from a surface onto adjacent discrete forcels (force sensing cells) by way of protrusions (small bumps or pegs), allowing for high-accuracy interpolation between adjacent discrete forcels. By minimizing active materials and computational complexity, MFR makes large-format floor tiles possible and economically feasible.
