Comparative Analysis of Infinite Scroll and Pagination Visual Interfaces on Spatial Memory in Mobile Digital Libraries - Open Data

This dataset contains anonymized behavioral data from a between-subjects randomized controlled trial (N=30) comparing Infinite Scroll and Pagination interface layouts on spatial memory formation in mobile digital libraries. Using a custom Android application (AYMobileDigitalLibrary), participants browsed a 30-item book catalog under one of two interface conditions, then completed tasks measuring global location recall (allocentric memory), local context recall (egocentric memory), and re-finding task performance. The dataset includes per-participant raw telemetry (CSV and JSON), demographic and baseline survey responses, post-task questionnaire ratings, and full interaction logs (scroll, tap, and page events).本数据集包含一项组间设计随机对照试验（N=30）的匿名行为数据，该试验对比了无限滚动（Infinite Scroll）与分页（Pagination）两种界面布局对移动数字图书馆空间记忆形成的影响。研究依托定制安卓应用（AYMobileDigitalLibrary）开展，参与者需在两种界面条件之一的环境下浏览包含30项图书的目录，随后完成多项任务，以测量全局位置回忆（以环境为中心的记忆，allocentric memory）、局部语境回忆（以自我为中心的记忆，egocentric memory）以及重新查找任务的完成表现。本数据集涵盖每名参与者的原始遥测数据（CSV与JSON格式）、人口统计学特征与基线调查问卷结果、任务后问卷评分，以及完整的交互日志（滚动、点击与页面切换事件）。
