US 2004/0017355 A1 · Cursor control systems and methods

Abstract

The present invention relates to cursor control systems and methods therefore for providing coarse and fine control in positioning cursors used on display screens of display units for information processing devices. In particular, the cursor control systems and related methods allow the user to move the cursor to a vicinity of a target position at a fast speed through an initial coarse maneuver, and then to precisely position the cursor in the target position at a slow or manual speed through a subsequent fine maneuver. An exemplary cursor control system typically includes a body, at least one fine controller, and at least one coarse controller. In general, the fine controller couples with the body, receives a first input signal from the user, and moves the cursor at the slow or manual speed as determined by the first input signal, while the coarse controller couples with the body, receives a second input signal from the user independently of the first input signal, and moves the cursor at the fast speed. Another exemplary cursor control system typically includes a cursor controller and an adjustor. In general, the cursor controller receive a first input signal from the user and generate an original output signal in response to the first input signal, while the adjustor has at least two settings, receives the original output signal from the cursor controller, receives a second input signal from the user independently of the first input signal to select one of the settings, processes the original output signal based on one of the settings selected by the user, and generates a final output signal based on the original output signal and the setting selected by the user. The information processing device receives the final output signal from the adjustor and moves the cursor on the display screen at the fast speed or at the slow or manual speed based on the final output signal.

Dependent claims

A cursor control system capable of moving at least one cursor at a plurality of speeds along a target path to a target position, wherein said cursor, target path, and target position are defined on a display screen of a display unit of an information processing device, and wherein said target position and target path are selected on said display screen by an user of said information processing device, said cursor control system comprising:

at least one cursor controller which is configured to receive at least one first input signal from said user and to generate at least one original output signal in response to said first input signal;
and
at least one adjustor which is configured to have at least two settings, to receive said original output signal from said cursor controller, to receive at least one second input signal provided by said user independently from said first input signal to select one of said settings, to process said original output signal based on said one of said settings selected by said user, and to generate at least one final output signal based on said original output signal and said one of said settings selected by said user,
wherein said information processing device is configured to receive said final output signal from said adjustor and to move said cursor on said display screen at one of said of speeds based on said final output signal.
