A Gesture- --based Mechanism for Text Selection on Touch Sensitive Screens

based Mechanism for Text Selection on Touch Sensitive Screens

Problem

We are using mobile devices with touch sensitive screens on a daily basis. When we need to select some text to copy or move, based on the current way of selecting text, we always need to tap the screen several times to trigger text selecting, to set the starting and ending point of the target text, and to call out the menu for further actions. The process is not smooth enough to create a good user's experience.

Prior arts

A: The current text selection method on Smart devices.

Drawback: User need to trigger the selection of a word or a paragraph first, and then specify the starting and ending point by separated touching and sliding. This method is not smooth enough.

This invention provides a systematic gesture-based method for the users to select desired text in a smooth and accurate way .

Advantage: Users can place the cursor, select the text, and copy the selected text using one series of consecutive slide gestures instead of multiple individual gestures, creating a better user's experience in selecting text.

This invention provides a systematic gesture-based method for the users to select desired text in a smooth and accurate way . Users can place the cursor, select the text, and copy the selected text using a series of consecutive slide gestures without having to detach the fingers from the screen for another tap gesture to relocate the cursor .

Step 1. Placing the cursor with 1 point touching

Touch the screen with one finger for one second to call out the cursor. The cursor appears above the touching point to avoid text being blocked by the touching finger. The cursor moves in correspondence with the movement of the touching point and automatically fit into the gap between characters when it gets near. Slide around the screen to place the cursor at the starting point of the target text (as shown in Figure 1).

This cursor placing process ends when the touching stops, or a second touching point is detected. The location of the cursor when this process ends will be recognized as the starting point of the text selection.
