'A white mask worked better': why algorithms are not colour blind - Guardian

A lot of your work concerns facial recognition technology. How did you become interested in that area?
When I was a computer science undergraduate I was working on social robotics - the robots use computer vision to detect the humans they socialise with. I discovered I had a hard time being detected by the robot compared to lighter-skinned people. At the time I thought this was a one-off thing and that people would fix this.

Later I was in Hong Kong for an entrepreneur event where I tried out another social robot and ran into similar problems. I asked about the code that they used and it turned out we'd used the same open-source code for face detection - this is where I started to get a sense that unconscious bias might feed into the technology that we create. But again I assumed people would fix this.

So I was very surprised to come to the Media Lab about half a decade later as a graduate student, and run into the same problem. I found wearing a white mask worked better than using my actual face.
