我们提出了我们的设计探索，在该地区的虚拟棒控制器和编辑任务的初步评估。虚拟摇杆控制器是解决触摸屏上精确指向问题的一种方法。它们通过使用触摸屏的一个区域作为移动指针的速率控制设备来操作。我们实现和评估这种技术在文本编辑的情况下，独立的插入符号的精确位置是困难的。结果表明，大字体和长指向距离定位插入符号与虚拟棒是显着慢于传统的手指触摸。相反，对于小字体和短指向距离，我们没有注意到任何差异。
We present our design exploration in the area of virtual stick controllers and a preliminary evaluation in an editing task. Virtual stick controllers are one solution to the problem of precise pointing on touch screens. They operate by using an area of the touch screen as a rate control device that moves a pointer. We implemented and evaluated this technique in a text editing context where unaided precise placement of the caret is difficult. The results showed that with large fonts and long pointing distance positioning the caret with the virtual stick is significantly slower than with conventional finger touching. On the contrary, with small fonts and short pointing distance, we noted no difference.
