Abstract:
1. A method for controlling a cursor on a touch screen, the method comprising: in response to having entered a pointing mode, displaying the cursor on the touch screen; in response to a touch on the touch screen, calculating a movement velocity of a touch point of the touch, and calculating a touch force of the touch based on one or more of: feedback from a pressure sensor on the touch screen, and a contact area with the touch screen, wherein the touch force is in direct proportion to the contact area with the touch screen; and controlling the movement of the cursor according to the movement velocity of the touch point, and also controlling the movement of the cursor based on the touch force by setting the movement velocity of the cursor to be in direct proportion to the touch force; wherein the controlling the movement of the cursor according to the movement velocity of the touch point comprises determining a location of the cursor according to the movement velocity of the touch point of the touch, refreshing the cursor at the location, and setting a proportion factor to adjust a relationship between the location of the cursor and the movement velocity of the touch point, such that the location of the cursor is determined using the formula: where p wherein at any moment in the pointing mode, an input area of the touch point is any area within the touch screen.
