Abstract:
Spatial navigation within a real 3-D maze was investigated to study space perception on the sole basis of tactile information transmitted by means of a ‘tactile vision substitution system' (TVSS) allowing the conversion of optical images—collected by a micro camera—into ‘tactile images’ via a matrix in contact with the skin. The development of such a device is based on concepts of cerebral and functional plasticity, enabling subjective reproduction of visual images from tactile data processing. Blindfolded sighted subjects had to remotely control the movements of a robot on which the TVSS camera was mounted. Once familiarised with the cues in the maze, the subjects were given two exploration sessions. Performance was analysed according to an objective point of view (exploration time, discrimination capacity), as well as a subjective one (speech). The task was successfully carried out from the very first session. As the subjects took a different path during each navigation, a gradual improvement in performance (discrimination and exploration time) was noted, generating a phenomenon of learning. Moreover, subjective analysis revealed an evolution of the spatialisation process towards distal attribution. Finally, some emotional expressions seemed to reflect the genesis of ‘qualia’ (emotional qualities of stimulation).

Abstract:
Postural control is essential for most activities of daily living. The impairment of this function can be extremely disabling. This work was stimulated by the testimony of a bilateral partial foot amputee who describes his difficulty in maintaining balance while washing his hair in the shower. We postulated that if the postural control system could not rely on accurate and reliable somatosensory inputs from the foot and ankle, as is probably the case following bilateral foot amputation due to the loss of the foot afferents and efferents, the weight of visual and vestibular cues would increase. We therefore assessed if a vestibular-to-tactile sensory substitution device could compensate for this impairment. Two separate experiments were conducted. Experiment 1: The effect of a vestibular-to-tongue tactile biofeedback balance system on the postural stability of this amputee was tested (on a force platform) and compared with a non-amputated, matched control group. The results showed that use of the biofeedback reduced centre of foot (CoP) displacement in all subjects but more spectacularly in the amputee. Experiment 2: The effect of the biofeedback was tested in 16 young healthy adults following a protocol of ankle muscle fatigue (known to alter ankle neuromuscular function and to perturb the control of bipedal posture). The results showed a significant decrease in CoP displacement compared with the control, non-biofeedback condition and a significantly greater effect of the biofeedback in the fatigue than the non-fatigue condition. Taken together, the results of these two studies suggest that an individual with double partial foot amputation was able to improve his balance control thanks to the use of a vestibular-to-tongue tactile biofeedback balance system and that young healthy individuals were able to take advantage of it to reduce the postural destabilisation induced by plantar-flexor muscle fatigue. Further studies are however necessary to confirm this in larger numbers of impaired persons as well as to assess the effectiveness in dynamic situations.

Abstract:
What is the relationship between the ‘haptic’ and the ‘tactile’ when it comes to media? We might question whether there is such a thing as ‘haptic media’; in other words, is there a type of media that invite the attention of one modality rather than another, or that foster certain types of interaction over others? If we were to speak about ‘haptic media’, to what extent does it engage directly (only) with touch, and to what extent does it involve some form of enhancement of another modality? In what ways can haptic media appeal beyond the visuocentric norm of the screen, and therefore to non-normate or disabled users? Further, to what extent does the haptic in particular benefit from ‘sensory substitution’, which is most usually of touch for vision in assisted living technologies for the blind, or of sound for touch for the deaf, for example? Certain historical instances of sensory substitution systems are discussed below, including Norbert Wiener’s ‘hearing glove’ and Bach-Y-Rita’s tactile–visual sensory substitution (TVSS) system, to make a larger argument about the role of haptic technologies, and haptic media, for more inclusive digital interactions.

Abstract:
In this paper, we present the results of an empirical study that aims to evaluate the performance of sighted and blind people to discriminate web page structures using vibrotactile feedback. The proposed visuo-tactile substitution system is based on a portable and economical solution that can be used in noisy and public environments. It converts the visual structures of web pages into tactile landscapes that can be explored on any mobile touchscreen device. The light contrasts overflown by the fingers are dynamically captured, sent to a micro-controller, translated into vibrating patterns that vary in intensity, frequency and temperature, and then reproduced by our actuators on the skin at the location defined by the user. The performance of the proposed system is measured in terms of perception of frequency and intensity thresholds and qualitative understanding of the shapes displayed.

Abstract:
Sensory substitution devices such as The vOICe convert visual imagery into auditory soundscapes and can provide a basic ‘visual’ percept to those with visual impairment. However, it is not known whether technical or perceptual limits dominate the practical efficacy of such systems. By manipulating the resolution of sonified images and asking naïve sighted participants to identify visual objects through a six-alternative forced-choice procedure (6AFC) we demonstrate a ‘ceiling effect’ at 8 × 8 pixels, in both visual and tactile conditions, that is well below the theoretical limits of the technology. We discuss our results in the context of auditory neural limits on the representation of ‘auditory’ objects in a cortical hierarchy and how perceptual training may be used to circumvent these limitations.

Vision is a very important tool for exploring the world in daily lives. The blind usually needs more time to be acquainted with the environment because of the imperfection of vision. If we can give them more information about the profile of the condition, it may take shorten time for them to be familiar with the environment without fumbling around. This study stems from an international cooperating project with Prof. Ehud Ahissar, the chairman of Weizmann Institute of Science in Israel. The purpose of this research is to develop prototype of tactile vision substitution system, TVSS. A TVSS converts visual information acquired from a CCD camera into tactile signals. So that the TVSS users can receive visual information by touching tactile signal generated by a tactile stimulator array attached on the skin. In this study, we probed into the image processing methods in TVSS, and built an image tracking system. The image processing methods in TVSS included image reducing, denoising, smoothing, image feature extraction, image feature combination, and image prettifying. The image tracking system used to find the region the active camera shoots, and then generated the moving route of the active camera, for the research in human experiments. We used the 2D wavelet transform sampling to reduce the image size. After comparing the kept power after 2D Wavelet transform sampling and the process time, we chose rbio6.8 as the mother wavelet for the downsampling process using discrete Wavelet transform. And we used a low-pass filter and mean shift smoothing method to eliminate noises and unnecessary textures. In image feature extraction, we chose the techniques of edge detection and thresholding, and combined the edge feature and color blocks to produce a feature image. Finally, we used the morphological closing operation to prettify the image. In the image tracking system, we first find the red laser point from the active camera by searching the maximum difference of the red pixel value between the image frame and previous image frame from the fixed camera. Then, by setting the coordinate of the red laser point to be the beginning, we searched for the most similar image region inside the fixed camera when compared with what active camera shot using correlation coefficient as a similarity index. The results showed the rate of image transforming to tactile signal was 1.5 sec per frame. Moreover, by adding the edge line, we can highlight the shape of objects when their colors were too close to the background in the image. The rate of image tracking system was 0.8 sec per frame. Although the tracking accuracy may sometimes be affected by the size difference of objects in images between the active camera and the fixed camera, high accuracy can still be preserved.

Abstract:
abstract: One type of assistive device for the blind has attempted to convert visual information into information that can be perceived through another sense, such as touch or hearing. A vibrotactile haptic display assistive device consists of an array of vibrating elements placed against the skin, allowing the blind individual to receive visual information through touch. However, these approaches have two significant technical challenges: large vibration element size and the number of microcontroller pins required for vibration control, both causing excessively low resolution of the device. Here, I propose and investigate a type of high-resolution vibrotactile haptic display which overcomes these challenges by utilizing a ‘microbeam’ as the vibrating element. These microbeams can then be actuated using only one microcontroller pin connected to a speaker or surface transducer. This approach could solve the low-resolution problem currently present in all haptic displays. In this paper, the results of an investigation into the manufacturability of such a device, simulation of the vibrational characteristics, and prototyping and experimental validation of the device concept are presented. The possible reasons of the frequency shift between the result of the forced or free response of beams and the frequency calculated based on a lumped mass approximation are investigated. It is found that one of the important reasons for the frequency shift is the size effect, the dependency of the elastic modulus on the size and kind of material. This size effect on A2 tool steel for Micro-Meso scale cantilever beams for the proposed system is investigated.

Abstract:
When a user integrates a sensory substitution device into her life, the process involves perceptual learning, that is, ‘relatively long-lasting changes to an organism’s perceptual system that improve its ability to respond to its environment’. In this chapter, I explore ways in which the extensive literature on perceptual learning can be applied to help improve sensory substitution devices. I then use these findings to answer a philosophical question. Much of the philosophical debate surrounding sensory substitution devices concerns what happens after perceptual learning occurs. In particular, should the resultant perceptual experience be classified in the substituted modality (as vision), in the substituting modality (as auditory or tactile), or in a new sense modality? I propose a novel empirical test to help resolve this philosophical debate.

Abstract:
According to proponents of the sensorimotor contingency theory of perception, active control of camera movement is necessary for the emergence of distal attribution in tactile-visual sensory substitution (TVSS) because it enables the subject to acquire knowledge of the way stimulation in the substituting modality varies as a function of self-initiated, bodily action. This chapter, by contrast, approaches distal attribution as a solution to a causal inference problem faced by the subject’s perceptual systems. Given all of the endogenous and exogenous evidence available to those systems, what is the most probable source of stimulation in the substituting modality? From this perspective, active control over the camera’s movements matters for rather different reasons. Most importantly, it generates proprioceptive and efference-copy based information about the camera’s body-relative position necessary to make use of the spatial cues present in the stimulation that the subject receives for purposes of egocentric object localization.
