Ziniu Hu, Yun Ma, Qiaozhu Mei, Jian Tang

TL;DR
This paper presents an empirical analysis of how Android users navigate between apps, revealing insights that can inform the design of better app navigation systems and reduce user effort.
Contribution
It offers the first detailed empirical study of inter-app navigation behaviors, introducing a model to classify pages and highlighting the potential of 'tunnels' to improve navigation efficiency.
Findings
Inter-app navigation is frequent and complex.
Developing 'tunnels' can significantly reduce navigation costs.
Practical implications for OS and app developers.
Abstract
Mobile applications (a.k.a., apps), which facilitate a large variety of tasks on mobile devices, have become indispensable in our everyday lives. Accomplishing a task may require the user to navigate among various apps. Unlike Web pages that are inherently interconnected through hyperlinks, mobile apps are usually isolated building blocks, and the lack of direct links between apps has largely compromised the efficiency of task completion. In this paper, we present the first in-depth empirical study of inter-app navigation behaviors of smartphone users based on a comprehensive dataset collected through a sizable user study over three months. We propose a model to distinguish informational pages and transitional pages, based on which a large number of inter-app navigation are identified. We reveal that developing 'tunnels' between of isolated apps has a huge potential to reduce the cost…
