This is a new idea for a smartphone application and is based on some already existing technologies for searching the web with pictures rather than keywords. Who’s That App would enable you to take a picture of someone you know or want to know better with your smartphone and would search the web for any matches based on face Recognition Software. Imagine being at a bar and falling head over heels for someone. You could either approach him or her and try get a phone number or email address or you could ask around if anyone you know knows that person. Who’s That App would provide another option - take a picture of the person and get to know him or her a little better through a Facebook page or anywhere else that person’s picture appears. Who’s That App would enable you to be more informed about the person you wish to approach. Dating and matchmaking services aside, Who’s That App is definitely something I’d like to have on my phone, simply because I hate seeing people in the street that I recognize and should remember their names but never do… Who’s That App would appeal to a very wide target audience and shouldn’t be all that expensive to develop considering the fact that it’s based on already existing picture search engines and facial recognition software. It should just be a matter of knitting them together – which is the new idea here – and developing an easy-to-use yet awesome graphic user interface.
