Investigating smartphone user differences in their application usage behaviors: an empirical study

Abstract

Smartphone applications (Abbr. apps) have become an indispensable part in our everyday lives. Users determine what apps to use depending on their personal needs and interests. Users with different attributes may have different needs, making it natural for their app usage behaviors to be different. The differences in app usage behaviors among users make it possible to infer their attributes. Knowing such differences could help improve mobile user experiences by enhancing smart services and devices. In this paper, we present an empirical study of investigating smartphone user differences on a large-scale dataset of recently used app lists from 106,672 Android users from China. We first investigate the user differences in app usage behaviors with respect to their attributes (gender, age, and income level). We find significant differences in app usage frequency, app usage with time context and functions. We then extract corresponding features from app usage records to infer the attributes of each user, and investigate the predictive ability of individual features and combinations of different individual features. We achieve the accuracy of 83.29% for gender, 69.94% for age (four age ranges) and 71.43% for income level (three income levels) with the best set of features, respectively. Finally, we discuss the implications of our findings and the limitations of this work.

Internet addiction and suicidal ideation among Chinese college students: the mediating role of psychotic-like experiences

“…Contrary findings have been obtained from one meta-analysis based on Chinese college students, indicating the prevalence of males in IA was found to be higher ( 8 ). This may be related to females’ increased demand for online social interactions (e.g., WeChat) ( 51 ) and online shopping (e.g., Taobao) ( 52 ). Among these college students, the self-reported prevalence of SI was 12.1%, slightly lower than the results of a survey of medical students with migraines using the same measure (13.7%) ( 44 ).…”

Smartphone App Usage Analysis: Datasets, Methods, and Applications

“…As a result, they recommended that developers consider cognitive function to better support older adults. Zhao et al [157] looked at how app usage differed by income level. They discovered that users with a higher income use apps in the categories of shopping, finance, travel, and business more frequently.…”

Cross-cultural usability evaluation of AI-based adaptive user interface for mobile applications

“…Based on 100,000 smart phone users' app lists, Zhao (Zhao et al, 2017;Zhao et al, 2019;Zhao et al, 2022), conducted research to elicit their traits and user attributes. An attribute-specific representation generation for the user characteristic was the first approach taken (Zhao et al, 2017) which was then expanded to build up a relationship between the app list and the attribute.…”

“…Based on 106,672 Chinese Android users (broken down into three income bands and four age ranges), an empirical study was undertaken (Zhao et al, 2019) to perform a detailed statistical analysis to see the intrinsic trends and relationships between the user and the app duration of usage, frequency of usage, functionalities utilised and the user's biometrics including financial status. The overall accuracy results obtained were: 83.29% (gender); 71.43% (income segments) and 69.94% (age bands).…”
