Abstract: In the era of digital intelligence, the proliferation of mobile applications has profoundly altered the way individuals interact with information and technology, posing challenges to the study of human information behavior and spurring the need for innovative research methods. The App Walkthrough Method, an emerging research approach, offers new opportunities and powerful tools for the investigation of human information behavior and human-computer interaction. This paper provides a systematic review of the App Walkthrough Method, sorting out the relevant research, examining in detail the evolution of the method's origin and its theoretical basis, elaborating the specific implementation steps, and analyzing in depth the research object and research theme. Furthermore, this paper proposes key areas for future research, aiming to bridge the gap between theoretical conceptualization and practical applications, and to offer a new research perspective and framework for the fields of human information behavior and user experience design.

Key words: App walkthrough method, Human information behavior, Interaction design, Research method, Sociocultural perspective
