Electronic device and touch control method thereof
First Claim
1. An electronic device comprising:
- a storage unit, configured for storing a relationship table recording a mapping relationship between handwritten touch inputs and a plurality of commands associated with the handwritten touch inputs;
a display unit for displaying an electronic file;
a touch input unit, configured for generating a trigger signal if a touch trace of a user on the displayed electronic file forming a closed loop having an enclosed region, sensing handwritten touch input by the user within the enclosed region and generating signals associated with the handwritten touch input; and
a processor, comprising;
a command identification module, configured for determining a command associated with the sensed handwritten touch input according to the relationship table in response to the trigger signal;
a content retrieving module, configured for retrieving content of the displayed electronic file within the enclosed region; and
a control module, configured for controlling executing the retrieved command to the retrieved content.

Abstract
A touch control method used for an electronic device storing a relationship table recording a mapping relationship between handwritten touch input and a number of commands includes the following steps. Display an electronic file. Sense a touch trace of a user on the displayed electronic file and generating a trigger signal if the touch trace forms a closed loop having an enclosed region. Sense handwritten touch input by the user within the enclosed region and generate associated signals. Recognize a circled path having an enclosed region as input by the user according to the generated signals. Determine a command associated with the sensed handwritten touch input according to the relationship table in response to the trigger signal. Retrieve content of the displayed electronic file displayed within the enclosed region. And execute the retrieved command to the retrieved content. An electronic device using the method is also provided.
