The Tangible Augmented Street Map (TASM) is a novel interface to geographic objects, such as tiled maps of labelled city streets. TASM uses tangible Augmented Reality, where a tangible object (i.e. a cube) is used to both scroll through and display digital maps. Hence the cube can be rotated to display maps that are adjacent to the current tile in geographic space. The cube is capable of theoretically infinite movement, embedded in a coordinate system with topology enabled. TASM has been tested for usability using heuristic evaluation, where selected experts use the cube, establishing non-correspondence with recognized usability principles. While general and vague, the heuristics helped prioritize immediate geographic and system-based tasks needed to improve the usability of TASM, also pointing the way towards a group of geographically-oriented heuristics.
