Smartphone Lock-screen Interface Design to Facilitate Return for Cross-service Bookmarks

Advances in the development of devices and expansion of communication have exposed new media users to vast amount of information, and the users, subsequently, have to make choice in consuming such information according to their needs. In such environment, a substantial portion of information simply flows to oblivion. Thus, the user finds it necessary to curate and filter the information in order to consume. Accordingly, browser favorites and many other related services have been developed to satisfy the user needs to save personal interests and manage the contents efficiently. But these services do not lead the users to the continued consumption of favorited contents, in other words, 'return.' This study was conducted by constructing image mapping through case studies and existing service analysis, drawing persona and scenario from interviews, and finally exploring the needs. At the end, we propose an interface to efficiently lead the users to return to favorited contents via lock-screen-the uppermost layer of smartphone.
