Tactile Map Open Stimulus Set (TMOSS)

The Tactile Map Open Stimulus Set (TMOSS) is a set of highly-controlled tactile maps for use in tactile/haptic experiments. The goal of having this database freely available is to facilitate rigorous and rapid experimentation in tactile perception. Using the information here, you can manufacture these stimuli. I have constructed the stimuli by laser-cutting clear acrylic, but other approaches are possible, including using the APH Tactile Graphics Kit, thermoforming, and printing on swell/microcapsule paper.

The TMOSS database consists of 56 tactile maps, each sized 12 in. x 12 in. These are broken into 7 groups of 8 maps. Many parameters are controlled so that they are the same for each map (e.g., there are 13 point symbols on every map), while other parameters are controlled so that they are the same for each group (e.g., there are the same 24 clusters of point symbols spread across the 8 maps in each group). A large number of parameters are controlled, in addition to the maps being constrained by tactile-map conventions and previous research. Therefore, the maps are applicable to many different experimental goals.
