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.

System and method of adjusting display characteristics of a displayable data file using an ergonomic computer input device

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.

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 wheel and associated structure, as well as the forces required to rotate and depress the wheel, are configured to reduce inadvertent actuation and to provide a user with tactile feedback, thereby allowing the user to accurately and intuitively activate the pointing device without exceeding an acceptable extension and range of motion for the user's finger and wrist. The mouse is coupled to a computer having a visual display device. The computer is capable of displaying a data file such as a word processing or spreadsheet document, where the data file has adjustable display characteristics such as size (zoom) or data structure (content). 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 at least two ways: spatial navigation and data 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. Other modes of spatial navigation allow the user to activate a roller switch, depress special function keys on a keyboard and/or move the mouse to pan, automatically scroll or manually scroll through the document. In data navigation, the user rotates the roller to view differing levels of content or detail with respect to the document.

System and method of adjusting display characteristics of a displayable

A system determining an intended cursor location on the computer display screen and automatically repositions the cursor at the intended location. If the user selects a command that alters the contents of the display, such as opening a new window, the system analyzes the new screen display to determine whether there are user selectable options associated with the new screen display. The system determines if one of the user selectable options is a default option and automatically positions the cursor at the default option. If the new screen display is an application program, the system attempts to locate a user selectable option and repositions the cursor at the user selectable option. When the new window is closed, the system returns the cursor to the position it was at before the new window was opened. The system also predicts an intended location for a screen display that has not been altered, and automatically positions the cursor at the intended location. This feature can be selectively enabled to prevent the inadvertent repositioning of the cursor in the display.

System and method for computer cursor control

A routine allows a user to move a cursor in only mutually perpendicular, horizontal or vertical directions on a computer screen, despite erratic or wavy movement of a pointing device. The routine, once enabled, receives mouse movement signals produced when the user moves the pointing device, the mouse movement signals having x and y position components. The routine uses the greater of the change in the x and y components to initially move the cursor in either horizontal or vertical directions, respectively. The routine continues to move the cursor along the initially established direction, even if the change in mouse movement signals in the other perpendicular direction become greater during continued mouse movement. Only when the change in mouse movement signals in the perpendicular direction become much greater (e.g., ten times greater) will the routine switch to moving the cursor along the perpendicular direction.
