Method and System for Turning off an Alarm of a Mobile Terminal

A method for turning off an alarm of a mobile terminal, the method comprising:

• performing an estimated setting according to a palm size and a touchscreen size, determining a value for presetting an area threshold value;
• automatically turning on a mobile terminal touchscreen when the alarm of the mobile terminal sets off;
• detecting a touch signal, when a touch signal is detected, calculating an area of a valid touch region in which a user touches the touchscreen;
• dividing the valid touch region into a plurality of graphics according to pre-stored graphics, calculating an area of each graphic and adding the area of each graphic to produce an area sum, and calculating the area of the valid touch region based on the area sum;
• comparing the calculated area of the valid touch region with the area threshold value, if the area of the valid touch region is greater than or equal to the area threshold value, controlling the mobile terminal to turn off the alarm.

A system for turning off an alarm of a mobile terminal, the system comprising:

• a storage module for storing a preset area threshold value;
• a detection module for detecting a touch signal;
• a calculation module for calculating an area of a valid touch region;
• a comparison module for comparing the area of the valid touch region with the area threshold value;
• an alarm control module for controlling the alarm according to a comparison result of the comparison module, wherein when the area of the valid touch region is greater than or equal to the area threshold value, controlling the mobile terminal to turn off the alarm, and wherein when the area of the valid touch region is smaller than the area threshold value, the alarm of the mobile terminal keeps ringing.
