The use of vibrotactile stimulation is increasing rapidly, and prominent examples of this increase can be found in the domain of sensory substitution (Dakopoulos & Bourbakis, 2010; Visell, 2009). The conceptual cornerstones of the ecological approach are crucial to research on sensory substitution: Whether perception occurs through normal vision (or other sense modalities) or with a sensory substitution device, the apprehension of environmental properties can be veridical only if information is detected that is specific to the properties to be perceived. For vision, specific information can often be identified as higherorder properties of the optic flow. As a consequence, the concept of optic flow has received wide attention in research on vision (Lee, 1980). Given that optic flow is crucial to vision, one might hypothesize that vibrotactile flow is crucial to vibrotactile sensory substitution. Which properties of the environment can be specified in vibrotactile flows? And which properties of vibrotactile flows can users detect? Our claim is that such questions are useful guidelines for research in the domain of sensory substitution (in line with several previous efforts; e.g., Mizuno, Ito & Okamoto, 2009). To illustrate our claim we designed a simple sensory substitution device. The present paper reports an experiment performed with the device. The experiment determines the detection threshold of step-on-places for blindfolded users.
