摘要： A position sensing system of a touch panel including a sensing unit and a decision unit is provided. When the touch panel is touched, the sensing unit obtains the sensing capacitances of p x-directional sensing lines and q y-directional sensing lines, wherein the sensing capacitances generated by these sensing lines exceed a threshold. The decision unit takes the central coordinates of the sensing lines with peak sensing capacitances as an x base coordinate and a y base coordinate, and adjusts the x base coordinate and the y base coordinate according to the ratios of the sensing capacitances of the other sensing lines to the peak sensing capacitance respectively to obtain an interpolated x coordinate and an interpolated y coordinate.

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.
