Electronic device, method for driving electronic device, and method for controlling data recording application

Abstract

One embodiment of the present invention relates to an electronic device for reproducing, in time sequence, first pen data in which handwriting strokes are digitized on a medium by an electronic pen. The electronic device comprises: a communication module; a control module; an output module for reproducing or outputting first handwriting information, first image or audio information photographed or recorded by the electronic device, and event information in time sequence; and a memory module for storing contents including the first handwriting information, the first image or audio information, and the event information, wherein, when the communication module further receives second pen data in a state where the first handwriting information is held on the output module after the contents are stored in the memory module, second handwriting information corresponding to the second pen data is added to the first handwriting information and then reproduced.
