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.

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.

A moving point gesture determination method is disclosed for a touch sense device mapped to a screen according to absolute position. The moving point gesture determination method includes steps of comparing one or more signal values of one or more detecting signals generated by the touch sense device with one or more threshold values, to determine whether any touch event occurs, and determining that a moving point gesture occurs once the determination indicates that a touch event occurs.

Disclosed is a click gesture determination method for a touch control chip capable of simply and flexibly determining a single click gesture. The click gesture determination method includes steps of comparing one or more signal values of one or more detecting signals with one or more threshold values, to determine whether a touch event occurs, continuing the above comparing if a touch event occurs, to detect a continuous occurrence time of the touch event, and comparing the continuous occurrence time with a first predefined time, and determining that a single click gesture occurs for a result of the comparison that the continuous occurrence time is longer than the first predefined time.

A driving method adapted to a touch-sensing display device is provided. The touch-sensing display device includes a display panel and a touch panel. The driving method includes following steps. A plurality of first scan signals of the touch panel are sequentially received, so that a plurality of first data values are obtained. It is determined whether the first data values are less than a difference between a baseline value and a threshold value. When one of the first data values is less than the difference between the baseline value and the threshold value, reporting of a touch coordinate of the touch panel is terminated. Furthermore, a touch-sensing device is also provided.
