Existing photo organizational tools on smartphones and related literature inherit similar design used in personal computers. However, in our formative user study, most users felt frustrated organizing their photos taken with smartphones, and photos taken for different purposes are mixed together by current design. We discovered from the user study that photos taken with smartphones can be summarized into three different categories - functional photos, event photos, and random snapshots. Supporting grouping of the three types of photos easily enables users to search and organize them more easily. Since supporting grouping of functional photos has not been well-explored, we put focus on discussing classifying functional photos automatically in this research. We collected both functional photos and non-functional ones from 14 participants. By using our methods combining the face model with texture and color features, it is able to achieve AUC about 0.861, an encouraging result considering the complex semantics of photos.
