This paper reports on the ongoing development of the TapTiles system, a low-cost, floor-interaction technology that overcomes problems found in previous overhead projector-based floor-interaction systems by using Light Emitting Diodes (LEDs) embedded into a carpet tile. Despite many advantages compared to projector-based floor interaction systems, LED-based systems could be criticized for lacking the resolution for a worthwhile interactive experience. User studies of both simulated and real hardware are reported on. This includes a comparison of tiles of different resolution that suggests that pixel density, over the range of tests, is less important than visual artifacts introduced by carpet tile edges. Contrary to initial expectations, denser LED spacing did not improve legibility or raise user preferences. Overall our studies suggest that LED-based floor interaction can be legible and effective in a walk-up and use situation.
