Abstract
Abstract An ergonomic pointing device, such as a mouse, includes a wheel to provide an input signal in addition to X and Y position signals provided by a rotatable ball of a standard mouse. The wheel extends from an upper surface of the pointing device and may be rotated and depressed by the finger of the user, the wheel being positioned and configured to allow a user to activate the wheel while maintaining a finger in a biomechanically neutral position. The mouse is coupled to a computer having a visual display device capable of displaying a data file having adjustable display characteristics. As a user rotates the roller, the mouse generates computer signals that are interpreted by an operating system and software applications running on the computer. The signals generated by the roller, together with a given software application, can be used in spatial navigation. In spatial navigation, a user rotates the roller to cause the computer and the visual display to zoom into and out of the document and thereby display increasing or decreasing magnification levels of the document on the display.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
107 words
A method of displaying displayable information on a display device of a computer system running an application program, the method comprising: the application program receiving a movement signal indicative of rotational movement of a movable member on a user input device; the application program displaying the displayable information within a computer generated display window having a window size at one of a plurality of magnification levels; and the application program changing the magnification level at which the displayable information is displayed based on the movement signal while maintaining the window size of the computer generated display window, regardless of movement of a pointer on the display device.
Claim 2
Independent Claim
107 words
A method of displaying displayable information on a display device of a computer system running an application program, the method comprising: the application program receiving a movement signal indicative of rotational movement of a movable member on a user input device; the application program displaying the displayable information within a computer generated display window having a window size at one of a plurality of magnification levels; and the application program changing the magnification level at which the displayable information is displayed based on the movement signal while maintaining the window size of the computer generated display window, regardless of movement of a pointer on the display device.
Claim 3
Dependent Claim
163 words
A computer system configured to display information on a display device, the computer system comprising: an information store configured to store displayable information wherein the display device is configurable to selectively display the displayable information within a computer generated display window having a window size at one of a plurality of magnification levels; a controller configured to receive a movement signal indicative of movement of a movable member movably coupled to a housing of a user input device and to control the display device to change the magnification level at which the displayable information is displayed based on the movement signal, while maintaining the window size of the computer generated display window, regardless of movement of a pointer on the display device; and wherein the controller is configured to receive the movement signal as a rotation signal indicative of rotation of a wheel rotatably coupled to an upper portion of a housing of the user input device among a plurality of discrete positions.
Claim 4
Dependent Claim
163 words
A computer system configured to display information on a display device, the computer system comprising: an information store configured to store displayable information wherein the display device is configurable to selectively display the displayable information within a computer generated display window having a window size at one of a plurality of magnification levels; a controller configured to receive a movement signal indicative of movement of a movable member movably coupled to a housing of a user input device and to control the display device to change the magnification level at which the displayable information is displayed based on the movement signal, while maintaining the window size of the computer generated display window, regardless of movement of a pointer on the display device; and wherein the controller is configured to receive the movement signal as a rotation signal indicative of rotation of a wheel rotatably coupled to an upper portion of a housing of the user input device among a plurality of discrete positions.
Claim 5
Dependent Claim
45 words
The computer system of claim 2 wherein the controller is configured to control the display device to change the magnification level at which the displayable information is displayed in a direction based on a direction of rotation of the wheel indicated by the rotation signal.
Claim 6
Dependent Claim
58 words
The computer system of claim 3 wherein the controller is configured to control the display device to change the magnification level at which the displayable information is displayed by one of a plurality of predetermined magnification levels based on rotation of the wheel from one discrete position to a next adjacent discrete position, based on the rotation signal.
