Claim 3:
4. A one-hand touch operation method, applied to a portable electronic device comprising a touch screen, the method comprising:
detecting a touch operation performed on the touchscreen, wherein the touch operation includes an operation comprising movement in a first direction followed by movement in a second direction in a sequence, wherein the second direction is a vertical direction alongside a screen edge of the touch screen and the first direction is a horizontal direction inward from the screen edge of the touch screen to a center of the touch screen;
determining whether a shift amount of the touch operation in the first direction is greater than a first non-zero threshold;
in response to determining the shift amount of the touch operation is greater than the first threshold:
activating a one-hand mode in response to determining a shift amount of the touch operation in the second direction is greater than a second non-zero threshold, and skip activating the one-hand mode and display another operation interface image in response to determining the shift amount of the touch operation in the second direction is not greater than the second threshold;
wherein the shift amount of the touch operation in the second direction comprises a difference between a coordinate component of a touch start position of the touch operation in the second direction and a coordinate component of a touch end position of the touch operation in the second direction;
providing a first visual prompt when the shift amount of the touch operation in the second direction increases to a preset value, the preset value being less than the second threshold, wherein the first visual prompt comprises separating an image boundary of the operation interface image from a second edge of the touch screen; and
zooming out or shifting the operation interface image and displaying the operation interface image in a one-hand mode interface display region in response to the one-hand mode being activated.
