触摸屏成为智能手机的主要输入设备。用户的触摸行为已经在实验室研究中得到了广泛的研究,参与者的数量相对较少。相比之下,我们在Android Market上发布了一款游戏,该游戏在执行受控任务以收集大量触摸事件时记录触摸行为。玩家的任务是简单地触摸屏幕上出现的圆圈。收集了91,731个装置的数据,玩家产生了120,626,225个触摸事件。我们确定了不同目标尺寸和屏幕位置的错误率。大量的数据使我们能够表明触摸位置是系统性的。一个补偿函数,转移用户的触摸,以减少错误的数量是从数据中得出的,并通过发布游戏的更新进行评估。使用来自12,201次安装和15,326,444次触摸事件的数据进行的独立测量实验表明,该功能将错误率降低了7.79%。我们认为,这种补偿功能可以提高几乎每个智能手机用户的触摸性能。
Touchscreens became the dominant input device for smartphones. Users' touch behaviour has been widely studied in lab studies with a relative low number of participants. In contrast, we published a game in the Android Market that records the touch behaviour when executing a controlled task to collect large amounts of touch events. Players' task is to simply touch circles appearing on the screen. Data from 91,731 installations has been collected and players produced 120,626,225 touch events. We determined the error rates for different target sizes and screen locations. The amount of data enabled us to show that touch positions are systematically skewed. A compensation function that shifts the users' touches to reduce the amount of errors is derived from the data and evaluated by publishing an update of the game. The independent-measures experiment with data from 12,201 installations and 15,326,444 touch events shows that the function reduces the error rate by 7.79%. We argue that such a compensation function could improve the touch performance of virtually every smartphone user.
