Determine the size of the pressure value of pressure；By the size of pressure value and default different pressing dynamics model Enclose and be compared, will when the size of the pressure value of pressure belongs to any one in pressing dynamics scope Pressure is defined as the pressing dynamics grade corresponding to the affiliated pressing dynamics scope.
In embodiments of the present invention, for the size of clear and definite pressure applied, we are in advance by different pressures Force value is defined as different dynamics grades, such as dynamics grade 1, dynamics grade 2, dynamics grade 3 ... according to This analogizes.The size of corresponding pressure value is that how much can enter according to different users in specific each grade The different definition of row, e.g., for young man, strength is larger, in the setting of dynamics grade each The larger pressure value of correspondence is could be arranged in grade, e.g., 50g-60g belongs to dynamics grade 1,60g-70g Belong to dynamics grade 2,70g-80g and belong to dynamics grade 3 (it should be noted that due to acceleration of gravity It is constant, the size of pressure is represented with weight here, is described below similarly.)；For the elderly and children For, strength is smaller, could be arranged to the less pressure of correspondence in each grade in the setting of dynamics grade Force value, e.g., 20g-35g, which belongs to dynamics grade 1,35g-50g and belongs to dynamics grade 2,50g-65g, to be belonged to Dynamics grade 3.The above is only the specific embodiment of the present invention, in other embodiments, we Can also be according to different application scenarios to dynamics grade and the size of the corresponding pressure value of each dynamics grade Do corresponding adjustment.
