Editing on a touchscreen

摘要

A touchscreen device is configured to facilitate editing on a touchscreen. The touchscreen device determines a position of a guide device on the touchscreen and determines an axis of the guide device on the touchscreen. The touchscreen device displays a first line on the touchscreen parallel to the axis of the guide device, while the touchscreen displays a second line on the touchscreen. The touchscreen device detects movement of the guide device on the touchscreen and moves the first line on the touchscreen based on the detected movement. The touchscreen device moves the first line to coincide with the second line in response to a determination that the first line is within the threshold distance of the second line. The touchscreen device then indicates that the second line is selected for potential editing.
