ABSTRACT

We investigated mobile users’ performance on text-only and text-and-icon menu interfaces of short and medium lengths. We conducted two experiments, with 18 participants each, on four mobile menus in two common usage situations, seated and walking. In Experiment 1, seated participants conducted known-item searches of word menus on short and medium text-only menus and short and medium text-and-icon menus. In Experiment 2, we replicated the first experiment in a walking context of use. We used selection time and error as performance measures in both experiments, plus walking speed in the second. Results showed that, when seated, participants recorded faster times in selecting targets with text-and-icon medium menu than text-only medium menu. Participants, when walking, had significantly faster selection times with text-and-icon short menu than text-only short menu, and with text-and-icon medium menu than text-only medium menu. Text-and-icon medium menu also resulted in fewer incorrect selections by users than text-only medium menu in the walking situation. Further, when comparing menus of the same length in the walking situation, text-and-icon menu had a more efficient learning curve than text-only menu. Walking speed was better with text-and-icon medium menu than text-only medium menu. We discuss results and highlight theoretical and practical implications.

摘要

我们调查了移动用户在中短长度的纯文本和文本和图标菜单界面上的表现。我们进行了两个实验，每个实验有 18 名参与者，在四个移动菜单上，在两种常见的使用情况下，坐着和走路。在实验 1 中，坐着的参与者在中短文本菜单以及中短文本和图标菜单上对单词菜单进行了已知项目搜索。在实验 2 中，我们在步行使用环境中复制了第一个实验。我们在两个实验中都使用选择时间和误差作为性能指标，在第二个实验中加上步行速度。结果表明，当参与者坐下时，使用文本和图标媒体菜单选择目标的时间比纯文本媒体菜单更快。参与者在行走时，文本和图标短菜单的选择时间明显快于纯文本短菜单，文本和图标中等菜单比纯文本中等菜单快得多。在步行情况下，文本和图标的中型菜单也比纯文本中型菜单减少了用户的错误选择。此外，在步行情况下比较相同长度的菜单时，文本和图标菜单比纯文本菜单具有更有效的学习曲线。文本和图标的中菜单比纯文本中菜单的步行速度更好。我们讨论结果并强调理论和实践意义。在步行情况下比较相同长度的菜单时，文本和图标菜单比纯文本菜单具有更有效的学习曲线。文本和图标的中菜单比纯文本中菜单的步行速度更好。我们讨论结果并强调理论和实践意义。在步行情况下比较相同长度的菜单时，文本和图标菜单比纯文本菜单具有更有效的学习曲线。文本和图标的中菜单比纯文本中菜单的步行速度更好。我们讨论结果并强调理论和实践意义。
