Wow congrats to the team! I met them when they were interviewing at YC. They were waiting around to pitch pg and gave me a demo.. I was speechless at the time and I quickly began thinking of all use cases this technology could work with.
congrats to them, never heard of them before. went to their website (after reading the note) and tried to find any documentation on how to use the app. found none other than you can "now use previous and forward". became immediately disinterested.
Obvious usage: Google is lagging behind their competition in the TV space. Apple's iTV, Ouya is taking Android into set-top space with their own ecosystem, Sony is bringing out the VitaStation... and then Microsoft and Valve have their higher-end devices that threaten to become general-purpose living-room computing/media machines beyond the hardcore gaming crowd.
The non-hardcore-gamer set-top space is getting crowded and Google TV flopped.
TV is the natural space for gestures, where a mouse and keyboard aren't practical. Microsoft knows this, Sony knows this - that's why Sony planned the camera as a standard feature for PS4 and only gutted it after cost concerns overwhelmed them.
I have always love Flutter. Yes it made me feel like a superhero !. i always showed my non techie friends Flutter how can i change a song just by waving. I was hoping to see more updates and features from you. Anyways. All the best
