This study describes when and how adolescents engage with their fast-moving and dynamic digital environment as they go about their daily lives. We illustrate a new approach - - for capturing, visualizing, and analyzing screenomes, the record of individuals' day-to-day digital experiences.
Over 500,000 smartphone screenshots provided by four Latino/Hispanic youth, age 14-15 years, from low-income, racial/ethnic minority neighborhoods.
Screenomes collected from smartphones for one to three months, as sequences of smartphone screenshots obtained every five seconds that the device is activated, are analyzed using computational machinery for processing images and text, machine learning algorithms, human-labeling, and qualitative inquiry.
Adolescents' digital lives differ substantially across persons, days, hours, and minutes. Screenomes highlight the extent of switching among multiple applications, and how each adolescent is exposed to different content at different times for different durations - with apps, food-related content, and sentiment as illustrative examples.
We propose that the screenome provides the fine granularity of data needed to study individuals' digital lives, for testing existing theories about media use, and for generation of new theory about the interplay between digital media and development.
本研究描述了青少年在日常生活中与快速变化且充满活力的数字环境互动的时间和方式。我们展示了一种新方法——用于捕捉、可视化和分析屏幕记录,即个人日常数字体验的记录。
来自低收入、少数族裔社区的4名14至15岁拉丁裔/西班牙裔青少年提供的超过50万张智能手机截图。
从智能手机收集一至三个月的屏幕记录,即设备激活时每五秒获取的智能手机截图序列,使用用于处理图像和文本的计算机程序、机器学习算法、人工标注和定性探究进行分析。
青少年的数字生活在不同人、不同日子、不同小时和不同分钟之间存在很大差异。屏幕记录突出了在多个应用程序之间切换的程度,以及每个青少年如何在不同时间以不同时长接触到不同内容——以应用程序、与食物相关的内容和情绪为例进行说明。
我们认为屏幕记录提供了研究个人数字生活所需的精细数据粒度,用于检验现有关于媒体使用的理论,并用于生成关于数字媒体与发展之间相互作用的新理论。
