Claim Text:
1. A proximity sensing method applied in a proximity sensing unit in a mobile device, the method comprising: comparing a sensed value of the proximity sensing unit with a predetermined offset value or a first predetermined range to determine if the sensed value is smaller than the predetermined offset value or if the sensed value is within the first predetermined range; comparing the sensed value stored in the mobile device with a predetermined value; and providing an offset value for confirming if an object is near the mobile device according to the determination that if the sensed value is smaller than the predetermined offset value or within the first predetermined range; wherein when the sensed value is within the first predetermined range, choosing the sensed value as the offset value for confirming if the object is near the mobile device; and otherwise, choosing the predetermined offset value as the offset value for confirming if the object is near the mobile device.
