Smartphone Usage Analysis Based on Actual-Use Survey

This paper presents a smartphone usage model that will be useful as ground data for works such as proposals on improving services/technologies related to smartphones. It is based on an actual-use survey involving about 700 smartphone users. We conduct web interviews with users to get their demographic data - age, sex, for example, and gather many kinds of usage traces from their device using our logger application. The model describes 1) daily usage pattern (combinations of application usages) and 2) pattern features - demographics, major application usages and so on. Through a cluster analysis of the usage traces, we find there are six typical daily usage patterns and half the users have multiple patterns that differ with the day.
