How can ‘fast’ lemons aid in providing vision for the blind?

With 40 million people worldwide classified as blind numerous methods have been developed to attempt to provide a visual percept to such populations. While invasive techniques such as retinal implants are both limited and costly, technological advancements and developments in perceptual science have facilitated low cost, non-invasive, interventions to provide the ‘missing’ input via alternative sensory systems. This sensory substitution not only provides useable technology but also gives insight into how we all process sensory information in a multisensory manner. In this talk I will discuss the crossmodal correspondences which drive the substitution algorithms and how these have been utilised in a number of sensory substitution devices. And just what are ‘fast lemons’ and how can they be used to provide visual information.
