A computer implementation of a classic memory card game was adapted to rely on touch rather than vision. Instead of memorizing pictures on cards, players explore tactile graphics on a computer-generated virtual surface. Tactile sensations are created by controlling dynamic, distributed lateral strain patterns on a fingerpad in contact with an electronic tactile display called STReSS2. The tactile graphics are explored by moving the device within the workspace of a 2D planar carrier. Three tactile rendering methods were developed and used to create distinct tactile memory cards. The haptic memory game showcases the capabilities of this novel tactile display technology.
