Below with reference to the flow chart description of Fig. 3 a example according to the cursor of mouse control method of Fig. 2.In this example, the cursor of mouse control method for movement is realized by a kind of remote controller key mouse algorithm.Specifically, some control word that remote controller key mouse algorithm sends telepilot, for example direction instructions such as upper and lower, left and right, upper left, lower-left, upper right, bottom right, and button is pressed and operational order such as is unclamped and carry out producing mouse event after the special processing, promptly make cursor of mouse move side-play amount dx and/or dy, then the mouse event that is produced is sent to the mouse processing module and handle, thereby the mobile of cursor of mouse controlled.This algorithm may operate in the appliance remote control, also may operate in telepilot receiving terminal equipment such as set-top box, the broadband integral intelligent terminal device (televisor that promptly possesses set-top box functionality) etc.
Remote controller key mouse algorithm of the present invention specifically describes as follows:
A) basic cursor of mouse offset equation:
dx＝±f(t) (1)
dy＝±f(t) (2)
In above formula, t represents that cursor of mouse moves the time span that operating key (being all directions key in this example) is pressed on the telepilot, dx and dy are the X-axis skews and Y-axis side-play amount of cursor of mouse, f (t) be relevant with time t one greater than 0 increasing function ,+/-by directionkeys decisions different on the telepilot.
B) several forms of f (t)
