Methods and apparatus for preventing accidental touch operation

摘要

Method and apparatus for preventing an accidental touch operation. The method includes determining, when detecting a touch point in a display area on a touch screen, whether the touch point is within an invalid touch area based on the detected touch point in the display area; and making a response to the touch point only if it is determined that the touch point is not within the invalid touch area. If it is determined that the touch point is within the invalid touch area, no response to the touch point is made.

1. A method for preventing an accidental touch operation, comprising:
determining a default area that is frequently touched in cases where a touch screen is operated accidentally on the touch screen for each of at least a first graphic interface and a second graphic interface; in response to initiating one of at least a first graphic interface and a second graphic interface, defining, using a menu, a first invalid touch area as an area associated with the first graphic interface that is frequently touched in cases where the touch screen is operated accidently based on a first set of pixel values input by a user and the default area for the first graphic interface, and a second invalid touch area as an area associated with the second graphic interface that is frequently touched in cases where the touch screen is operated accidently based on a second set of pixel values input by the user and the default area for the second graphic interface; detecting a touch point in a display area on the touch screen; detecting which of the first graphic interface and the second graphic interface is displayed; determining, using a processor, whether the touch point is within the first invalid touch area based on the detected touch point in the display area when the first graphic interface is displayed and is within the second invalid touch area based on the detected touch point in the display area when the second graphic interface is displayed; and making a response to the touch point only based on a determination that the touch point is not within an associated invalid touch area.
