The present paper initially presents to the reader the most prominent results in the field of SSD (Sensory Substitution Devices) for the visually impaired population. Afterwards, a technical-ergonomic comparison is held, where some important academic and commercial projects in the last decade are highlighted. Several transcendental discoveries in this matter are depicted and at the end a new promising method is introduced, making use of Haralick texture features. The main finding of the present work is that this approach could present to the visually impaired texture-like properties of the image based on its physical characteristics, and even more, since the Haralick approach is mathematically rigorous, then it may render a more coherent and congruent image-to-sound algebra than previous methods.
