17 is a flowchart of a method for determining a touch input according to an exemplary embodiment.

According to an embodiment, the electronic device 301 may detect a touch input to the frame 353 . For example, even if the electronic device 301 does not include a sensor for sensing a touch input directly to the frame 353 , the electronic device 301 may display a frame based on the input to the first display area and the second display area. An input to (353) can be detected. Hereinafter, the first display area may be referred to as the first display area 1361 described with reference to FIGS. 8A and 13A . The second display area may be referred to as the second display area 1362 described in relation to FIGS. 8A and 13A .

In operation 1705, the electronic device 301 may detect a touch input through at least one of the first display area and the second display area.

In operation 1710 , the electronic device 301 may determine whether the sensed touch input is a simultaneous touch input through the first display area and the second display area. When a touch input is detected only in one of the first display area or the second display area (eg, in operation 1710 -N), in operation 1725 , the electronic device 301 provides information about one display area corresponding to the touch input. It can be determined by input. For example, when a touch input is detected only for the first display area, the electronic device 301 may process the touch input as an input for the first display area. For example, when a touch input is detected only for the second display area, the electronic device 301 may process the touch input as an input for the second display area.

When a touch input is detected in both the first display area and the second display area (eg, operation 1710 -Y), in operation 1715 , the electronic device 301 may determine whether the touch input satisfies a specified condition. For example, a touch input sensed by the first display area may be referred to as a first touch input, and a touch input sensed by the second display area may be referred to as a second touch input. According to an embodiment, the electronic device 301 may determine whether a specified condition is satisfied based on the location of the first touch input and the location of the second touch input. For example, if the distance between the position of the first touch input and the position of the second touch input is within a specified distance, the electronic device 301 may determine that the specified condition is satisfied. For example, the specified distance may be 1 cm. As another example, the electronic device 301 may determine whether a specified condition is satisfied based on a ratio between the first distance and the second distance. A distance between the first touch input and the frame 353 may be referred to as a first distance, and a distance between the second touch input and the frame 353 may be referred to as a second distance. The electronic device 301 may determine that the specified condition is satisfied when the longer distance among the first distance and the second distance is within twice the shorter distance. As another example, in the electronic device 301, if the distance between the position of the first touch input and the position of the second touch input is within a specified distance, and the deviation of the first distance and the second distance is within the specified range, the specified condition can be determined to be satisfied.

When a specified condition is satisfied (eg, in operation 1715 -Y), in operation 1720 , the electronic device 301 may determine the touch input as an input to the frame 353 . For example, the touch input is a swipe input for the first display area and the second display area (eg, a swipe input in a direction substantially perpendicular to the extending directions of the first display area and the second display area); When the touch input satisfies the specified condition, the electronic device 301 may determine the touch input as a swipe input for the frame 353 .

When the specified condition is not satisfied (eg, in operation 1715 -N), in operation 1730 , the electronic device 301 may determine a touch input as an input to the first display area and the second display area. For example, the electronic device 301 may process a touch input as a plurality of touch inputs of a first touch input and a second touch input. The electronic device 301 may recognize a first touch input to the first display area and a second touch input to the second display area.

According to an embodiment, the electronic device 301 may set the direction of the first scroll input to the first display area 1361 and the direction of the second scroll input to the second display area 1362 to be different from each other. . For example, the electronic device 301 responds to a swipe input in an up or down direction (eg, an extension direction of the first display area 1361 or the second display area 1362 ) with respect to the first display area 1361 . So the text can be scrolled. The electronic device 301 may display the third text 1823 that is not currently displayed in the first display area 1361 based on the upward scroll input. For example, the electronic device 301 may scroll an image according to a swipe input in a left or right direction with respect to the second display area 1362 . The electronic device 301 may display the third image 1823 based on a left swipe input. The electronic device 301 may display the first image 1821 based on a rightward swipe input.
