The invention relates to a method for implementing the dynamic optimization of soft keyboard layout, and the method comprises the steps that a soft keyboard can predict a key value which may be inputted by a user next time according to a received key value when the soft keyboard receives the key value inputted by the user at each time, orders the hit rates of key value prediction, adjusts the position of the key value with the highest hit rate to a designated position, moves a current cursor to the position, takes the current cursor as the center, and arranges other predicted key values around the current cursor according to the ordering of the hit rates, wherein the number of jumps from the key value with the higher hit rate to the current cursor is smaller. According to the invention, the method can reduce the number of jumps of cursor movement for a soft keyboard user, improves the input efficiency of the user, and greatly improves the user experience especially in the application of input through a television remote controller.
