Does anyone know how the categories are associated with the projects?

The article does not claim that the glasses prevent face detection. It claims that they prevent face recognition. These two concepts are different.

Face detection - determine the location of a face or faces in an image.

Face recognition - given a location of a face in an image, correctly predict who's face it is.
