A pointing device comprises a mouse tablet having a regular repetitive pattern of field sensitive pixels on the surface thereof, and a mouse including coupling elements movable across the mouse tablet, wherein the coupling elements establish position-dependent field coupling with the pixels. Analysis of the coupling yields mouse motion and direction of motion. In one embodiment, the pixels are deployed in rows and columns and a pair of coupling elements are provided for sensing motion and direct...

An improved computer mouse allows a computer operator to interactively adjust horizontal and vertical resolution by depressing switches on the mouse frame and moving the mouse frame on a flat surface. Optional indicators on the mouse frame indicate a plurality of resolution settings. An internal sounding device within the mouse assembly provides audio feedback as the resolution is changed. The invention connects to a standard Personal Computer (PC) through a serial RS-232 port or a standard para...

A table editor for editing a table of rows and columns using a pointing device and display station. The table editor stores information about the lines and boxes that make up the table. A pointing device is used to select horizontal or vertical lines or a box defined by horizontal and vertical lines for an operation. The user can select a command to insert rows or columns, to delete rows or columns, or to concatenate the contents of two or more boxes. The determination of whether rows or columns...

A computer mouse capable of stimulating therapeutic points of the human body to reduce user fatigue. Projection bodies for stimulating the therapeutic points are provided on the main body and click buttons of the computer mouse.

A third axis input device for a computer mouse includes a fixed primary seat, a fixed secondary seat, a wheel, an annular ring-like grating member, a suspending member, and an idle roller, characterized in that: the fixed primary seat has a lower portion provided with a first fixed rod and a first L-shaped hook member adapted to engage with a printed circuit board, a recess between the fixed rod and the L-shaped hook member for receiving a photoelectric controller, two arms provided at two sides...

A desktop operated computer control mouse including a housing, electronic circuitry within the housing, a user manipulable rotatable ball for pointing control, a plurality of finger depressible buttons exposed on the housing and interfacing with sensors electrically connected with the circuitry. At least some of the finger depressible buttons are for user selection of signals to be sent to the computer for window or screen scroll control, and are associated with sensor(s) which are pressure-sens...

A low-cost tactile feedback mouse device for providing haptic feedback to a user for enhancing interactions and manipulations in a graphical environment provided by a computer. The mouse device includes a sensor device able to detect the movement of the mouse in the planar workspace. An actuator is coupled to the housing of the mouse and applies an inertial force in a particular degree of freedom, preferably along an axis perpendicular to the planar workspace, where the inertial force is transmi...

An improved pointing device with ergonomic features is provided. The pointing device allows an operator's hand to remain in a relaxed position in as near a state of repose as possible while operating the pointing device. The shape of the pointing device reduces several of the known high risk postures during use.

A mouse operable in a narrow space on a desk or the like without interposing an operation of lifting the mouse off a mouse pad, moving it in the air and putting it down on the mouse pad. The mouse comprises a moving amount sensor for detecting moving amounts of the mouse in a first area set on a mouse pad, and a second area outside the first area, a button arranged on the mouse, an area sensor for detecting whether the mouse is located in the first or second area, and a signal generator for, whe...

A computer mouse designed for reducing vandalism of its components. In the preferred embodiment, gripping surfaces are removed or impeded on the disk for holding the trackball in place. Accordingly, this makes it difficult for vandals to move the disk to its unlocked position to steal the ball or vandalize the components of the mouse.
