Touch Determining Method and Determining Method of Touch Gesture on a Touch Panel
First Claim
1. A determining method for a touch gesture on a touch panel, the method comprising:
- determining whether a first valid touch is present on the touch panel;
determining whether a second valid touch is present on the touch panel within a predetermined time period of the first valid touch being determined as present, when the first valid touch is continuously detected; and
generating a first instruction when the second valid touch is determined as not present within the predetermined time period.

Abstract
A determining method of touch gesture on a touch panel is provided to avoid misjudgment of determination of a multi-finger touch as a single-finger touch. The method includes determining whether a first valid touch is present on the touch panel; determining whether a second valid touch is present on the touch panel within a predetermined time period when the first valid touch is continuously present within the predetermined time period; generating a first hand gesture instruction when the second valid touch is not detected during the predetermined time period; and generating a second hand gesture instruction when the second valid touch is detected within the predetermined time period.

12. A determining method of a touch on a touch panel, the method comprising:
-
receiving a plurality of detection values from the touch panel; respectively determining whether the detection values are larger than a first predetermined value; detecting a trend of variances of the detection values, that are larger than the first predetermined value, to determine a first detection value, a second detection value, and a third detection value from the detection values that are larger than the first predetermined value, wherein a first touch group of detection values is determined according to a first detection value and a second detection value, and a second touch group of detection values is determined according to the second detection value and a third detection value; and respectively determining whether the first touch group and the second touch group are valid touch groups to determine a number of the valid touch groups. - View Dependent Claims (13, 14, 15, 16)
