 The multimodal mental imagery of the visually impaired plays an important role in various ways in which they can navigate their environment. Cane use and brail reading rely on the subject’s visual mental imagery triggered by tactile input as does echolocation, a more and more widespread means by which blind people can learn to gather information about the spatial layout of their environment (by making clicking sounds and use the echo of these sounds as the source of spatial information). It is now known that echolocation relies on processing in the early visual cortices: it is visual mental imagery that is triggered auditorily (Thaler et al. 2011). Finally, sensory substitution devices also create visual mental imagery. These devices consist of a video camera mounted on the head of the blind subject that provides a continuous stream of tactile or auditory input (transferred from the visual input the camera registers – for example gentle needle pokes on the subject’s skin in a pattern that corresponds, in real time, with the image the camera records). This tactile input then leads to processing in the early visual cortices of these blind subject (which then gives rise to an experience that the subjects characterize as visual). In short, what is referred to as sensory substitution assisted perception is in fact another example of multimodal mental imagery (Renier et al. 2005, see Nanay 2017a for a summary).
