ABSTRACT

Screen mirroring might be a way to improve older adults’ user experience of smart televisions (STVs) through smartphones. To examine this possibility, two experiments were conducted. Experiment I examined older adults’ difficulties of screen mirroring (mirroring smartphone screens to STVs) through five common touch gestures (“Drag,” “Slide,” “Zoom,” “Draw,” and “Handwrite”), in comparison to younger adults. The results indicated that a major problem for older adults is the frequent attention switching between the STV and smartphone screens. Therefore, experiment II explored how to reduce the need of attention switching through the touch gestures (“Tap,” “Slide + Tap,” and “Slide + Release”) and the button sizes (8, 14, and 20 mm) for different input postures. Thirty older adults participated in this experiment and their eye movements were tracked. Four major findings were derived. First, the “Zoom,” “Draw,” and “Handwrite” gestures in screen mirroring were difficult for older adults with a task completion rate lower than 68%. Second, the problem of frequent attention switching between the STV and smartphone was predominant for tapping tasks. Third, the “Slide + Tap” and “Slide + Release” touch gestures helped to reduce attention switching in tapping tasks more than the “Tap” for older adults, while the “Slide + Release” received the worst subjective feedback. Fourth, increasing the button size from 8 mm to 14 mm on smartphones can improve the task completion rate and the task efficiency in screen mirroring when older adults used the one-handed posture to tap.

屏幕镜像并不像看起来那么简单:通过触摸手势近距离观察老年人的跨设备体验

摘要

屏幕镜像可能是改善老年人通过智能手机使用智能电视 (STV) 的一种方式。为了检验这种可能性,进行了两个实验。实验我通过五种常见的触摸手势(“拖动”、“滑动”、“缩放”、“绘图”和“手写”)检查了老年人在屏幕镜像(将智能手机屏幕镜像到 STV)方面的困难,与年轻人相比. 结果表明,老年人的一个主要问题是在 STV 和智能手机屏幕之间频繁切换注意力。因此,实验二探讨了如何通过触摸手势(“点击”、“滑动+点击”和“滑动+释放”)和按钮尺寸(8、14 和 20 毫米)来减少对不同用户的注意力切换的需要。输入姿势。三十名老年人参加了这个实验,他们的眼球运动被跟踪。得出了四个主要发现。首先,屏幕镜像中的“缩放”、“绘图”和“手写”手势对于任务完成率低于 68% 的老年人来说是困难的。其次,STV 和智能手机之间频繁切换注意力的问题是点击任务的主要问题。第三,对于老年人来说,“滑动+点击”和“滑动+释放”触摸手势比“点击”更有助于减少点击任务中的注意力切换,而“滑动+释放”的主观反馈最差。第四,将智能手机的按键尺寸从8mm增加到14mm,可以提高老年人单手敲击时的任务完成率和投屏任务效率。”和“手写”手势在屏幕镜像中对于任务完成率低于 68% 的老年人来说是困难的。其次,STV 和智能手机之间频繁切换注意力的问题是点击任务的主要问题。第三,对于老年人来说,“滑动+点击”和“滑动+释放”触摸手势比“点击”更有助于减少点击任务中的注意力切换,而“滑动+释放”的主观反馈最差。第四,将智能手机的按键尺寸从8mm增加到14mm,可以提高老年人单手敲击时的任务完成率和投屏任务效率。”和“手写”手势在屏幕镜像中对于任务完成率低于 68% 的老年人来说是困难的。其次,STV 和智能手机之间频繁切换注意力的问题是点击任务的主要问题。第三,对于老年人来说,“滑动+点击”和“滑动+释放”触摸手势比“点击”更有助于减少点击任务中的注意力切换,而“滑动+释放”的主观反馈最差。第四,将智能手机的按键尺寸从8mm增加到14mm,可以提高老年人单手敲击时的任务完成率和投屏任务效率。对于老年人来说,“滑动 + 敲击”和“滑动 + 释放”触摸手势比“敲击”更有助于减少敲击任务中的注意力切换,而“滑动 + 释放”收到的主观反馈最差。第四,将智能手机的按键尺寸从8mm增加到14mm,可以提高老年人单手敲击时的任务完成率和投屏任务效率。对于老年人来说,“滑动 + 敲击”和“滑动 + 释放”触摸手势比“敲击”更有助于减少敲击任务中的注意力切换,而“滑动 + 释放”收到的主观反馈最差。第四,将智能手机的按键尺寸从8mm增加到14mm,可以提高老年人单手敲击时的任务完成率和投屏任务效率。
