“…Back-y-Rita's tvss enabled blind subjects to feel objects exterior to their bodies via substitution of vision by artificially produced vibrotactile patterns [4]. A most interesting, minimalist variant is described by Lenay et al where distal attribution is reported to occur for single-site, single-taps vibrotactile stimuli given under the proper sensorimotor coupling [52,36].…”

This paper surveys more than twenty types of tactile illusions and discusses several of their aspects. These aspects include the ease with which they can be demonstrated and whether they have clear visual analogs. The paper also shows how to construct equipment made of simple supplies able to deliver well controlled tactile signals in order to conveniently demonstrate four different tactile illusions.

“…Tactile based systems continue the tradition of Bach-y-Rita and his original Tactile Vision Sensory Substitution (TVSS) device (Bach-y-Rita, Collins, Saunders, White, & Scadden, 1969), which acted on the skin of the back. More recent tactile systems have used a fingertip (Kaczmarek, Tyler, & Bach-y-Rita, 1997) and the tongue (Bach-y-Rita, Kaczmarek, Tyler, & Garcia-Lara, 1998).…”

Sensory substitution is a promising technique for mitigating the loss of a sensory modality. Sensory substitution devices (SSDs) work by converting information from the impaired sense (e.g., vision) into another, intact sense (e.g., audition). However, there are a potentially infinite number of ways of converting images into sounds, and it is important that the conversion takes into account the limits of human perception and other user-related factors (e.g., whether the sounds are pleasant to listen to). The device explored here is termed “polyglot” because it generates a very large set of solutions. Specifically, we adapt a procedure that has been in widespread use in the design of technology but has rarely been used as a tool to explore perception—namely, interactive genetic algorithms. In this procedure, a very large range of potential sensory substitution devices can be explored by creating a set of “genes” with different allelic variants (e.g., different ways of translating luminance into loudness). The most successful devices are then “bred” together, and we statistically explore the characteristics of the selected-for traits after multiple generations. The aim of the present study is to produce design guidelines for a better SSD. In three experiments, we vary the way that the fitness of the device is computed: by asking the user to rate the auditory aesthetics of different devices (Experiment 1), and by measuring the ability of participants to match sounds to images (Experiment 2) and the ability to perceptually discriminate between two sounds derived from similar images (Experiment 3). In each case, the traits selected for by the genetic algorithm represent the ideal SSD for that task. Taken together, these traits can guide the design of a better SSD.

“…The image is converted into tactile stimulus (for example pressure or vibration) on a plate which is in contact with the subject's back or tongue. After some practice, subjects learn to locate the position of things recorded by the camera (Bach-Y-Rita et al 1969). There must be some difference between random twinges on the back and the stimulus provided by the plate converting the camera's image.…”
