Presenting Peekaboo



Today, we presented our final year design project, Peekaboo, to the University of Waterloo. I thought it was only fair that I post it online on the same day as well.

Peekaboo is an iOS app that lets you find out more about people around you. It accomplishes this by using facial detection and recognition. Simply snap a picture and Peekaboo tries to find out who the people in it are. You can login to the app using Facebook, and it goes through your tagged Facebook photos to create a model of your face. Don’t have or don’t want to connect with Facebook? Peekaboo can train you using your phone’s front-facing camera.

Watch the short video

I thought a video would explain it better than words can. This was taken on my iPhone 4S and recorded using AirPlay. It’s a slightly old build.

The idea

We started with the idea of wanting to know more about people in university. If you think about it, there are 10,000 like-minded students in a university campus but I only know 0.01% of them, due to a random moment that made me meet them. That 0.01% is responsible for most of the joy and friendships that I have created in the last 4 years. So what if this 0.01% was larger? We felt that there should be a better way of knowing more about people around you, so that you can meet more like-minded individuals. Is Peekaboo the right approach? I’m not totally sure, and it certainly has polarizing aspects, but it sure was fun to make.

The technology

I mentioned how I designed Peekaboo’s system architecture in an earlier post. Some things have changed since then. We found face.com provided us improved facial recognition and had a faster execution time, so we went with that. This allowed us to simplify a lot of the code on the C++ side, effectively making the system a combination of the iOS app and a Node.js server on Heroku that acted as an API that linked to the various services, Parse and Face.com.

I was responsible for coding the majority of the Node.js server and the iOS app. My goal throughout this process was to become proficient with Objective-C and the iOS SDK and I think I’ve got close.
