The primary strength of google has been search. How about using google glasses for finding physical things in the real world. "Tell me where I kept my red shirt?", "Where is the my Algorithms book?", "Where did I keep my phone charger", "Let me look for a pen to note down ... ah i can't find it", "Ah its raining can't find my umbrella. Google do you remember where you saw it last?" ... sounds familiar.

Google could potentially index my room and help me find some things. Sounds futuristic but doable nevertheless. Automatic face recognition is an obvious thing to come. But I can save hours of my time if my physical world was also indexed. This idea did not strike me when the #ifihadglass competition was still running. May be someone already posted something similar. May be google is secretly working this idea. They could also be patenting it. Thoughts?
