最近，带有触摸屏的便携式终端的普及引人注目。这些终端可以轻松操作。此外，用户界面设计允许屏幕界面的灵活设计。然而，由于用户拇指的宽度较大，准确操作终端变得困难。因此，许多研究尝试改善图标/按钮的可操作性；然而，只有少数人关注滑块。滑块存在两个操作问题：一是由于滑块拇指尺寸较小或滑块位置不合适，导致拖动前难以精确指向；其次是用户无法正确定位滑块。在本研究中，我们进行了两个实验来克服这些问题。第一个实验表明，当滑块拇指的尺寸大于8.0毫米时，滑块拇指可以准确、快速地指向，并且其位于屏幕的中心。第二个实验表明，当移动比率为0.7或0.8时，调整位置所需的时间和拖动操作的主观易用性都得到改善。此外，当移动比率减小到0.3时，滑块拇指调节更加精确。
The recent spread of portable terminals with touch-sensitive screens has been remarkable; these terminals can be operated easily. Moreover, user interface design allows for a flexible design of the screen interface. However, owing to the large width of the user’s thumb, operating the terminal accurately becomes difficult. Therefore, many studies have attempted to improve the icon/button operability; however, only a few have focused on sliders. Sliders have two operational problems: first is the difficulty in precisely pointing before dragging owing to the small size of the slider thumb or inappropriate position of the slider; and second is the inability of the user to correctly position the slider. In this study, we conduct two experiments to overcome these problems. The first experiment reveals that the slider thumb can be pointed accurately and quickly when the size of the slider thumb is greater than 8.0 mm, and it is positioned in the center of the screen. The second experiment shows that both the time taken to adjust the position and subjective ease of the drag operation improve when the movement ratio is 0.7 or 0.8. Additionally, when the movement ratio is decreased to 0.3, the slider thumb adjustment is more precise.
