So when we are on snapchat, we can see our friends current locations or public stories based on locations on world map, on Yelp/facebook you can see your friend check in a particular location with a sentiment etc. I was wondering what if we integrate Social media with AR, such that if for example my friend Raj checked in restaurant BBq nation and could share what he ordered, and how was he feeling! And if you're somewhere near that location and open your social app then it notifies you of a public AR message! This can be a AR action from premade set of options by the social app or based on your sentiment or any information the app collects at that time, can automatically create an AR story for you! These are my questions: 1. Is there already something like this? 2. Would you want to use anything like this? If yes, any reasons! 3. Why wouldn't you want to use this if any! 4. Any use case other than just pure entertainment or as a unique experiment?
