The navigation through vibration feature is unique. It means you don’t have be looking at a screen while walking and it works offline. It’s not necessarily only tourists that would use this. The plan to create wearables and walking sticks with this feature could help the visually impaired (for example) navigate cities (including their own) much easier. If the vibration navigation technology becomes a standard feature of walking sticks and other tools the visually impaired use, it will greatly increase accessibility. I think this makes the project especially interesting. Too bad it’s underplayed somewhat in the whitepaper.
