The article described an SSD (sensory substitution device) that converts a particular color under a stylus into a sound.
I wonder if you could build an SSD that did a playback of a 2-dimensional scan of an input image in such a way that a blind person could rebuild the 2-dimensional image. Perhaps the brain could pick up something akin to CRT horizontal scan lines. Also, I wonder whether stereophonic output would be advantageous.
- joelg 9y agoThis is actually exactly the topic of the 3Blue1Brown video on Hilbert Curves: https://www.youtube.com/watch?v=3s7h2MHQtxc https://www.youtube.com/watch?v=3s7h2MHQtxc Space-filling curves are a sort of optimal mapping strategy for compressing two dimensions down into one.
