A few years ago, I was very inspired by Daniel Kish and others who use echolocation. So I started a side project called Project Sonorous. Sonorous was a prototype to explore combining AR with echolocation and 3D audio. This allows you to translate visual spatial information into echolocation-like audio cues through headphones.

I would still love to work on this idea in the future. But it would require a lot of funding and advanced technology (similar to that used by self-driving cars.)
