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.

Claims

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.

2. The method as recited in claim 1, wherein said handheld communication device transmits data to, and receives data from a communication network utilizing radio frequency signals.

3. The method as recited in claim 1, wherein said handheld communication device comprises a lighted display located above a keyboard suitable for accommodating textual input to the handheld communication device when said handheld communication device is in an operable configuration, said auxiliary user input being located essentially between the display and keyboard in the operable configuration.

4. The method as recited in claim 3, wherein said auxiliary user input is a trackball.

5. The method as recited in claim 4, wherein motion of the trackball is assessed using a plurality of sensors that quantify rotational motion of the trackball about an intersecting x-axis and an intersecting y-axis of the trackball.

6. The method as recited in claim 5, wherein said plurality of sensors number two, one of said two sensors outputting signals indicative of x-component rolling motion of the trackball relative to the handheld communication device and about the intersecting y-axis of the trackball and the other of the two sensors outputting signals indicative of y-component rolling motion of the trackball relative to the handheld communication device and about the intersecting x-axis of the trackball.

7. The method as recited in claim 6, wherein said two sensors are oriented radially about the trackball with approximately ninety degree spacing therebetween.

8. The method as recited in claim 7, wherein each of said two sensors is a hall effect sensor located proximate said trackball.

9. The method as recited in claim 5, wherein said plurality of sensors number four, a first pair of opposed sensors outputting signals indicative of x-component rolling motion of the trackball relative to the handheld communication device and about the intersecting y-axis of the trackball and a second pair of opposed sensors outputting signals indicative of a y-component rolling motion of the trackball relative to the handheld communication device and about the intersecting x-axis of the trackball.
