The invention discloses a method and a system for correcting the touch center of a touch screen according to user behaviors. The method comprises the following steps: when a situation that a user carries out a touch operation is detected, selecting the first n points with a maximum sub-electrode capacitance change quantity as candidate points; judging whether a previous operation of the user is a cancel operation or not; if the previous operation of the user is the cancel operation, extracting a cancel icon which aims at the previous operation; setting a weight for each candidate point, wherein the weight of the candidate point corresponding to the cancel icon is set to be lowest; utilizing the sub-electrode capacitance change quantity and the weight of each candidate point to calculate an electrode capacitance change weighted value of each candidate point; taking the sum of the capacitance change weighted values of all candidate points which belong to the same icon as a weighted sum of the corresponding icon; and taking the icon with the maximum weighted sum as the icon corresponding to a user touch center point. The historical behavior of the user is used for correcting touch selection which is carried out at present so as to more approach to the real intention of the user.
Description
technical field [0001] The invention relates to the field of touch input, in particular to a method and system for modifying the touch center of a touch screen according to user behavior. Background technique [0002] The capacitive screen is the mainstream material of the touch screen on the mobile terminal, which is divided into two types: projection type and surface type. The projected type capacitive screen is the mainstream implementation method of the capacitive screen. [0003] For the surface capacitive screen, when touching the screen, due to the formation of a coupling capacitance between the finger and the conductor layer, the current from the electrodes on the four sides will flow to the contacts, and the strength of the current is proportional to the distance from the finger to the electrode. The control behind the touch screen The device will calculate the proportion and strength of the current, and calculate the position of the touch center point. [0004] Th...
