Abstract
A cursor (13) is positioned on a display (5) in response to a user input (12) on a pointing device (10). The user input, which represents a desired cursor movement (14) on the display, is converted to time varying magnitude and argument components in polar space. The magnitude component is processed so as to control a speed of movement of the cursor on the display. Separately from this, the argument component is processed so as to suppress rapid angular variations in the movement of the cursor on the display.
Claims18
A method of positioning a cursor on a display in response to a user input on a pointing device, the user input representing a desired cursor movement on the display, wherein the user input is converted to time varying magnitude and argument components in polar space, and wherein the magnitude component is processed so as to control a speed of movement of the cursor on the display, the method comprising the step of processing the argument component, separately from the processing of the magnitude component, so as to suppress rapid angular variations in the movement of the cursor on the display.
An electronic apparatus comprising a display, a user-controlled pointing device, a controller adapted to control a position of a cursor on the display in response to a user input on the pointing device, and a polar converter adapted to convert the user input to time varying magnitude and argument components in polar space, the apparatus comprising:
- an argument filter, the argument filter being adapted to process the argument component so as to suppress rapid angular variations in the positioning of the cursor on the display.
