Face recognition on Android isn't exactly new - the Sony Ericsson XPERIA X10, when it finally goes on sale, will be able to identify people in photos
and link them to their Contacts entries - but a new app promises facial recognition for all Android devices. Recognizr is the handiwork of The Astonishing Tribe
, and its gimmick is that it can ID people and link them not only to information on your phone, but to their various online social network and blog identities.
Currently in proof-of-concept stage, there are a few caveats to bear in mind. Most pressing is that anyone you want to "scan" with Recognizr has to have also registered with the system before they can show up. That's not particularly surprising, when you think about it; there's no public-access database of faces linked to social networks which it could build upon.
A public release is expected in the next few months.
