System and method of adjusting display characteristics of a displayable data file using an ergonomic computer input device
First Claim
1. A computer readable medium storing instructions which, when executed by a computer, cause the computer to perform 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.

Abstract
An ergonomic pointing device, such as a mouse, is coupled to a computer having a visual display device. As a user rotates a roller associated with the mouse, 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 for spatial navigation. In spatial navigation, a user rotates the roller to cause the computer and the visual display to increase or decrease magnification levels of the document on the display. Other models of spatial navigation allow the user to activate a roller switch, depress special function keys on a keyboard and/or move the mouse to pant, automatically scroll or manually scroll through the document.

2. A method of displaying information on a display device, the method comprising:
-
storing in an information store displayable information; selectively displaying the displayable information on the display device within a computer generated display window having a window size at one of a plurality of magnification levels; receiving a movement signal, at a controller, indicative of movement of a movable member movably coupled to a housing of a user input device; controlling the display device with the controller 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 receiving the movement signal at the controller comprises receiving 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. - View Dependent Claims (3, 4)
