Here is another exciting Kickstarter project that is clearly a harbinger of things to come. As you can see in this little video, CamFind's concept is "mobile visual search". Google already introduced this concept with Google Goggles, but the people behind CamFind say their technology is at least 4 times more accurate.
It is however easy to imagine what would happen if you combined this sort of tech with something like Google Glass. In essence the entire process you see here taking place on an iPhone would actually happen right in your field of vision. People around you wouldn't even be aware of the fact that you are busy researching them or checking out how much they paid for their furniture or new outfit.
Just as exciting as it is creepy, no ?
