Patent ID: 8773380

Claim:
A method for updating an interface of a touch screen, comprising: a first operation of determining, from location information on coordinates of and time information on a last preset number of sampled pixel points through which a sliding trace of a control body sliding on the touch screen passes, a distance over which and a period of time in which the control body slides from the first one to the last one of the sampled pixel points in a movement direction of the display interface; a second operation of determining, from the distance and the period of time, the highest speed v 0 at which the control body slides with a zero initial speed and a constant acceleration a 0 starting from the first sampled pixel point to the last sampled pixel point and the acceleration a 0 ; and a third operation of periodically determining a step by which a menu is adjusted and updating the display interface at a preset interval T of updating the interface assuming that the interface slides starting with an initial speed of v 0 or of the product of v 0 and a first weight and with a deceleration of a 0 or of the product of a 0 and a second weight after the control body is released so that the display interface is updated with an effect of decelerated sliding until it stops at an optimum display location, wherein a period of time in which the interface slides between two consecutive instances of updating thereof is preset to T 0 .
