Electronic device with touch screen and method and system for protecting same
First Claim
1. A method for protecting an electronic device with a touch screen, comprising:
- detecting a distance between the touch screen and an object in front of the touch screen;
determining whether the distance is less than or equal to a distance limit;
determining whether a touch action is applied to the touch screen in a first predetermined time when the distance is less than or equal to the distance limit;
determining whether the electronic device is put into a pocket of a user with its touch screen facing outwardly when no touch action is applied to the touch screen within the first predetermined time;
sending a warning to a user when the electronic device is put into the pocket of the user with its touch screen facing outwardly; and
determining whether the object remains within the distance limit for duration of a second predetermined time,wherein if a duration of time of the object remaining within the distance limit is greater than the second predetermined time, determining whether the touch action is applied to the touch screen within the first predetermined time;
wherein the first predetermined time and the second predetermined time have equal lengths.

Abstract
An electronic device comprises a touch screen, a distance determining module, a touch determining module, and a warning control module. The distance determining module determines whether a distance between the touch screen and an object in front of the touch screen is less than or equal to a distance limit. The touch determining module determines whether a touch action is applied to the touch screen within a first predetermined time when the distance between the touch screen and the object is less than or equal to the distance limit. The warning control module controls the electronic device to send a warning to a user when no touch action is applied to the touch screen within the first predetermined time.

4. A system for protecting an electronic device with a touch screen, comprising:
-
a distance determining module determining whether a distance between the touch screen and an object in front of the touch screen is less than or equal to a distance limit and determining whether the object determined as being within the distance limit remains inside the distance limit for the duration of a second predetermined time; a touch determining module determining whether a touch action is applied to the touch screen within a first predetermined time when the distance between the touch screen and the object is less than or equal to the distance limit and determining whether the touch action is applied to the touch screen in the first predetermined time when the duration of time of the object remaining within the distance limit is greater than the second predetermined time; and a warning control module controlling the electronic device to send a warning to a user when no touch action is applied to the touch screen within the first predetermined time. - View Dependent Claims (5, 6)
