摘要： 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.
