Ahoi! I’ve been working on this project for some while now and I thought it was about time for an update. The tactile sensory substitution display has changed greatly since the last iteration, mostly in terms of electronics, currently it’s running at 10×10 pixels with a much faster refresh rate than the previous iteration. Previously I had it running a face detection program to isolate faces and present them to the wearer on their back, giving people additional information about their environments, here’s a video of me using the old haptic display:
The new electronics uses shift registers to load up chars which describe the video information, this makes it easier to send the data in streams and allows for a faster refresh.
