A method for controlling static and quasi-static devices for pointing the cursor on the screen of interactive systems, the method comprising: providing an actuation element having a button and being subject to control actions that have a lateral component; periodically sensing the components of the control action in directions x and y; processing signals corresponding to the components in the directions x and y; calculating the modulus and the direction parameters of the movement; converting the modulus according to a preset conversion rule; storing, at each cycle, the values of the modulus, of the corrected modulus, and of the direction parameters; transferring and restoring the values; feeding the values of the current cycle and the values of the previous cycle, toward elements for calculating components of the incremental movements in directions x and y to be imparted to the cursor; feeding the components to an adder element, and processing signals to be transmitted to the connected interactive system for controlling movements of the cursor matching control actions. A logic unit is also provided for carrying out the method. |
