Display interface updating method for touch screen and multimedia electronic device

摘要

An interface updating method for touch screen and a multimedia electronic device are provided, which are used for solving the problem of how to update a display interface of a touch screen according to the slide operating characteristics of a controller. When the controller slides on the touch screen, the operating characteristics of the controller are determined based on the predetermined number of pixel point samples that the slide trail of the controller goes through at last. The interface is updated according to the operating characteristics of the controller. The interface adjustment visually obtains an effect corresponding to the movement of the controller.

1. 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 v0 at which the control body slides with a zero initial speed and a constant acceleration a0 starting from the first sampled pixel point to the last sampled pixel point and the acceleration a0; 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 v0 or of the product of v0 and a first weight and with a deceleration of a0 or of the product of a0 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 T0.
