Method and terminal device for selecting character

A terminal device, comprising:

• a touch screen for displaying content;
• a processor;
• and
• a memory for storing instructions executable by the processor,
• wherein the processor is configured to execute instructions for:
• detecting a touch point of a user gesture acting on the touch screen, wherein the touch point falls into a touch point node;
• searching a plurality of nodes of the contents to find a nearest text node to the touch point, when the touch point node is not a text node;
• and
• selecting a nearest character to the touch point within the nearest text node,
• wherein the plurality of nodes are organized as a node tree, and wherein searching the plurality of nodes comprises:
• determining whether the touch point node contains any text node;
• calculating the distance between the touch point and each text node contained in the touch point node when the touch point node contains at least one text node;
• and
• selecting the text node of the smallest distance as the nearest text node to the touch point.

A non-transitory readable storage medium including instructions, executable by a processor in a terminal device, for performing the method for selecting a character from content displayed in a touch screen, the method comprising:

• detecting a touch point of a user gesture acting on the touch screen, wherein the touch point falls into a touch point node;
• searching a plurality of nodes of the contents to find a nearest text node to the touch point, when the touch point node is not a text node;
• and
• selecting a nearest character to the touch point within the nearest text node,
• wherein the plurality of nodes are organized as a node tree, and wherein searching the plurality of nodes comprises:
• determining whether the touch point node contains any text node;
• calculating the distance between the touch point and each text node contained in the touch point node when the touch point node contains at least one text node;
• and
• selecting the text node of the smallest distance as the nearest text node to the touch point.
