摘要:
A method for determining a displacement of a touch point is applied to a touch panel to reduce noise interfering with determination of the displacement. The method includes obtaining a displacement according to a movement of a touch point on the touch panel; checking whether the displacement is within a predetermined range; and determining that the movement is valid when the displacement is within the predetermined range.

A hand gesture recognition method according to the present disclosure is applied to a touch panel comprising a plurality of sensors, each of which generating a sensing value according to a touch operation. The method includes providing a first reference value and a second reference value; generating a count value by counting a quantity of the sensing values that are greater than a threshold; determining the touch operation as a first hand gesture when the count value is greater than the first reference value but smaller than the second reference value; and determining the touch operation as a second hand gesture when the count value is greater than the second reference value.

A signal processing method for a touch panel is provided. The touch panel includes several capacitor electrodes. The method includes the following steps. Detection values are provided according to self-capacitance changes of the capacitor electrodes. The detection values are then low-pass filtered by a filter structure to generate several filtered values. A position where a touch event occurs on the touch panel is determined according to the filtered values.

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.
