A systemic smartphone usage pattern analysis: Focusing on smartphone addiction issue

Despite the recent massive popularity of smartphones and their impact on our lifestyles, only few objective studies have been conducted on smartphone usage patterns. In this paper, using a comprehensive smartphone usage logging system (a client app and a server), various statistical analysis results from more than 800 man-days usage logs are presented. The anal-ysis shows 1) significant difference in usage frequency and time statistics among the applica-tions, 2) different application category preferences between addicts and non-addicts, and 3) little usage variation between weekdays and weekends, but higher usage in night time for addicts. © 2014 SERSC.
