    • A method for detecting a single-finger rotation gesture and a gesture detecting circuit thereof are provided. The gesture detecting circuit comprises a quadrant dividing unit, a register, a control unit, a comparing unit, and an outputting unit. The quadrant dividing unit, according to the center point, divides a touch panel into at least three quadrants and sets a plurality of data codes respectively corresponding to the quadrants. Within a predetermined time, the control unit controls the register to sequentially record the data codes respectively corresponding to the touched quadrants. When the predetermined time is reached, the comparing unit compares to judge whether the temporary data buffered in the register is the same with the default data. If the temporary data is the same with the default data, then the outputting unit outputs a rotation gesture signal.
    • 提供了一种用于检测单指旋转手势的方法及其手势检测电路。 手势检测电路包括象限分割单元,寄存器,控制单元,比较单元和输出单元。 根据中心点,象限分割单元将触摸面板划分为至少三个象限,并分别对应于象限设置多个数据代码。 在预定时间内,控制单元控制寄存器顺序地记录分别对应于触摸的象限的数据代码。 当达到预定时间时,比较单元进行比较以判断缓冲在寄存器中的临时数据是否与默认数据相同。 如果临时数据与默认数据相同,则输出单元输出旋转手势信号。

    • A method for double click detection includes the following steps. Firstly whether first event is detected is determined, if so, first corresponding position is obtained, a period counting is triggered, and first flag is set. Then whether the period ends is judged; if not and the first flag exists, a counter is incremented and second flag is set when first ending event is detected; if not and the second flag exists, second corresponding position is obtained and third flag is set when second event is detected; if not and the third flag exists, the counter is incremented when second ending event is detected; if so, a double click event is determined when the incremented value is greater than a threshold and a distance between the first and the second positions is smaller a threshold.
    • 一种用于双击检测的方法包括以下步骤。 首先确定是否检测到第一事件,如果是,则获得第一对应位置,触发周期计数,并且设置第一标志。 那么是否判断期限结束? 如果不存在,并且第一标志存在,则计数器递增,并且在检测到第一个结束事件时设置第二标志; 如果不存在,并且第二标志存在,则获得第二对应位置,并且在检测到第二事件时设置第三标志; 如果不存在,并且第三标志存在,则当检测到第二结束事件时,计数器递增; 如果是,则当递增值大于阈值并且第一和第二位置之间的距离小于阈值时确定双击事件。
