ON-SCREEN DIAGONAL CURSOR NAVIGATION ON A HANDHELD COMMUNICATION DEVICE
First Claim
1. A method for affecting diagonal movement of a cursor on a display screen of a handheld communication device, said method comprising:
- sensing movement at an auxiliary user input of the handheld communication device indicative of the user'"'"'s desire to affect diagonal movement of the cursor on the display screen of the handheld communication device;
producing x-direction signals and y-direction signals based on said sensed movement at the auxiliary user input;
holding the cursor steady on the display screen while processing said x-direction signals and y-direction signals until a predetermined criterion is met for discriminating whether the user has indicated x-direction cursor movement, y-direction cursor movement or diagonal cursor movement; and
affecting diagonal cursor movement on the display screen of the handheld communication device when diagonal cursor movement is discriminated to have been user indicated.

Abstract
Method an arrangement for affecting diagonal movement of a cursor 171 on the display screen 322 of a handheld communication device 300. The method includes sensing movement at an auxiliary user input 328 of the handheld communication device 300 indicative of the user'"'"'s desire to affect diagonal movement of the cursor 171 on the display screen 322 of the handheld communication device 300. X-direction signals and Y-direction signals are produced based on the sensed movement at the auxiliary user input 328. During that time while the necessary signals are being collected and processed, the cursor 171 is held steady on the display screen 322 until a predetermined criterion is met for discriminating whether the user has indicated x-direction cursor movement, y-direction cursor movement or diagonal cursor movement.

17. A method for affecting diagonal movement of a highlighting cursor amongst an array of icons on a display screen of a handheld communication device, said method comprising:
-
sensing movement at an auxiliary user input of the handheld communication device indicative of the user'"'"'s desire to affect diagonal movement of the highlighting cursor from a currently highlighted icon on the display screen to a diagonally located icon on the display screen of the handheld communication device;
producing x-direction signals and y-direction signals based on said sensed movement at the auxiliary user input;
holding the highlighting cursor steady on a presently highlighted icon on the display screen while processing said x-direction signals and y-direction signals until a predetermined criterion is met for discriminating whether the user has indicated movement to an icon left or right of the presently highlighted icon, above or below the presently highlighted icon, or diagonally positioned relative to the presently highlighted icon; and
affecting diagonal movement of the highlighting cursor between diagonally positioned icons on the display screen of the handheld communication device when diagonal cursor movement is discriminated to have been user indicated. - View Dependent Claims (18, 19, 20, 21)

22. A handheld communication device capable of affecting diagonal movement of a highlighting cursor amongst an array of icons on a display screen of the handheld communication device, said handheld communication device comprising:
-
a lighted display located above a keyboard suitable for accommodating textual input to the handheld communication device;
an auxiliary user input located essentially between the display and keyboard;
sensors capable of sensing movement at the auxiliary user input indicative of the user'"'"'s desire to affect diagonal movement of the highlighting cursor from a currently highlighted icon on the display screen to a diagonally located icon on the display screen of the handheld communication device, said sensors producing x-direction signals and y-direction signals based on said sensed movement at the auxiliary user input; and
a processor capable of analyzing the produced x-direction signals and y-direction signals and outputting a cursor control signal that holds the highlighting cursor steady on a presently highlighted icon on the display screen during said processing and until a predetermined criterion is met for discriminating whether the user has indicated movement to an icon left or right of the presently highlighted icon, above or below the presently highlighted icon, or diagonally positioned relative to the presently highlighted icon and then affecting diagonal movement of the highlighting cursor between diagonally positioned icons on the display screen of the handheld communication device when diagonal cursor movement is discriminated to have been user indicated. - View Dependent Claims (23, 24, 25)
