Touch input determining method which can determine if the touch input is valid or not valid and electronic apparatus applying the method
First Claim
1. A touch input determining method applied to an electronic apparatus with a main controller for performing a predetermined function based on at least one touch input, a sub-controller for computing a tilt angle of the electronic apparatus, an environment sensing device, a touch sensing device and a display, wherein the method is performed when the main controller is in a sleep mode, the display is off and the touch sensing device is off, comprising:
- applying the sub-controller to compute the tilt angle of the electronic apparatus according to an environment parameter received from the environment sensing device while the main controller is in the sleep mode;
applying the sub-controller used to compute the tilt angle to activate the touch sensing device without turning on the display if the tilt angle falls in a predetermined angle range, while the main controller is in a sleep mode;
determining a size of a region on the touch sensing device that an object provides the at least one touch input to;
keeping the display off if the sub-controller determines the size is larger than a first predetermined value or if the sub-controller determines the size is smaller than a second predetermined value, wherein the second predetermined value is smaller than the first predetermined value; and
the sub-controller waking the main controller from the sleep mode and activating the main controller to turn on the display and to control the electronic apparatus to perform the predetermined function according to a gesture formed by the touch input if the size is smaller than the first predetermined value and larger than the second predetermined value.

Abstract
A touch input determining method applied to an electronic apparatus with a touch sensing device, which comprises: (a) determining a size for a region of the touch sensing device that an object provides at least one touch input to; (b) if the size is larger than or equals to a first predetermined value, not determining the touch input is a valid touch input; and (c) if the size is smaller than or equals to a second predetermined value, not determining the touch input is a valid touch input, wherein the second predetermined value is smaller than the first predetermined value.

14. An electronic apparatus with a touch input determining mechanism, comprising:
-
an environment sensing device; a display; a touch sensing device; and a processing module, comprising; a main controller, configured to perform a predetermined function based on at least one touch input; a sub-controller, configured to compute a tilt angle of the electronic apparatus according to an environment parameter received from the environment sensing device while the main controller is in a sleep mode, and configured to compute the tilt angle to activate the touch sensing device without turning on the display if the tilt angle falls in a predetermined angle range, while the main controller is in the sleep mode; wherein the processing module is further configured to perform following steps when the display is off; determining a size of a region on the touch sensing device that an object provides the at least one touch input to; wherein the processing module keeps the display off if the sub-controller determines the size is larger than a first predetermined value or if the sub-controller determines the size is smaller than a second predetermined value, wherein the second predetermined value is smaller than the first predetermined value; wherein the sub-controller wakes the main controller from the sleep mode and activates the main controller to turn on the display and to control the electronic apparatus to perform the predetermined function according to a gesture formed by the touch input if the size is smaller than the first predetermined value and larger than the second predetermined value. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
