## Abstract

A method for operating an electronic device is provided. Aspects include configuring a touch slop corresponding to a reference for performing a scroll in response to detection of a first touch event and acquiring touch information corresponding to a current touch point every predetermined time while the first touch event is maintained. Based on a determination that a touch movement distance exceeds the touch slop, based on the acquired touch information, aspects include initiating a scroll for a first screen displayed on the display module. Aspects further include identifying scroll data comprising at least one of a movement speed, a movement distance, and deceleration of the first touch event, based on the touch information acquired while the scroll is performed and determining whether to end the scroll, based on the scroll data to control a state of the scroll for the first screen.

identify a movement speed for each scroll interval while the scroll for the screen is performed based on the touch information; and
change the first threshold value to a value smaller than a predetermined value based on a determination that an average speed calculated based on the identified movement speed is equal to or lower than a predetermined speed.

### Claim 8 (depends on 1)

The electronic device of claim 1, wherein the instructions, when executed by the at least one processor, further cause the electronic device to:
identify a scroll map stored in the memory in response to detection of the first touch event;
