Abstract:
1. An apparatus for controlling a cursor on a touch screen, the apparatus comprising: a display module configured to, in response to having entered a pointing mode, display the cursor on the touch screen; a calculating module configured to, in response to a touch on the touch screen, calculate a movement velocity of a touch point of the touch, and calculate 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 a control module configured to control the movement of the cursor according to the movement velocity of the touch point, and also control 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 control module is further configured to control the movement of the cursor according to the movement velocity of the touch point by 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.
