US 8,913,023 B2 · Electronic device and touch control method thereof

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.
