Visual Behaviors and Mobile Information Acquisition

摘要:

人们在移动中从事信息获取任务是很常见的。为了了解用户的视觉行为如何影响微学习(一种移动信息获取形式),我们对8名参与者进行了一项阴影研究,并确定了三种常见的视觉行为:“扫视”,“检查”和“漂移”。我们发现“漂移”最能支持移动信息获取。我们还确定了四个与用户相关的因素,可以影响利用移动信息获取的机会:态势感知,转换成本,持续的认知过程,并意识到机会。我们进一步研究了这些用户相关的因素如何与设备相关的因素相互作用,通过技术探针与20名参与者使用手机和光盘头安装显示器(OHMD)。研究结果表明,不同的设备平台显着影响如何移动信息采集的机会被使用:OHMD可以更好地支持移动信息采集时,视觉注意力分散。OHMD有助于缩短任务与环境之间的视觉转换时间,从而减少任务转换的心理障碍。另一方面,移动电话在更稳定的环境中提供更集中的体验。基于这些发现,我们讨论了权衡和设计的影响,支持信息采集任务的移动。

英文摘要:

It is common for people to engage in information acquisition tasks while on the move. To understand how users' visual behaviors influence microlearning, a form of mobile information acquisition, we conducted a shadowing study with 8 participants and identified three common visual behaviors: 'glance', 'inspect', and 'drift'. We found that 'drift' best supports mobile information acquisition. We also identified four user-related factors that can influence the utilization of mobile information acquisition opportunities: situational awareness, switching costs, ongoing cognitive processes, and awareness of opportunities. We further examined how these user-related factors interplay with device-related factors through a technology probe with 20 participants using mobile phones and optical head-mounted displays (OHMDs). Results indicate that different device platforms significantly influence how mobile information acquisition opportunities are used: OHMDs can better support mobile information acquisition when visual attention is fragmented. OHMDs facilitate shorter visual switch-times between the task and surroundings, which reduces the mental barrier of task transition. Mobile phones, on the other hand, provide a more focused experience in more stable surroundings. Based on these findings, we discuss trade-offs and design implications for supporting information acquisition tasks on the move.
