*6.1. User Interface*

Guided by the above requirements, our system is designed as Figure 4. The interface consists of six major UI components: (a) a view mapping user's multi-dimensional features into two-dimensional space and showing in the feature space; (b) a list of whole users' detailed features sorted based on LOF anomaly scores; (c) some statistical information for each segment; (d) a novel ego network glyph inspired by the solar system for visualizing the structure of the ego's network and the relationship between alters and egos; (e) a statistical view representing the active time and habit of the ego; (f) a detail view to display the contact between ego and each alter and the anomaly of each alters. In summary, (a), (b), (c) compose our group view, (d) is our ego view, and (e) and (f) are our detail view. We will introduce the design of them as follows.
