Description
Background of the Invention
1. Field of the Invention
The present invention relates to a computer input device.
More particularly, the present invention relates to a computer input device, similar to a joystick or mouse, but uses palm pressure rather than the wrist for the input.
2. Description of the Prior Art
Much of the interaction between computers and human operators centers on a flashing marker, or cursor, that appears on a computer's video screen. The cursor indicates where the next action will be displayed and moves in response to commands from the keyboard. For example, typing a character moves the cursor one position to the right; striking one of the specially designated cursor keys can move the marker in one of four directions--up, down, left or right.
The most widely used alternative pointing device is the mouse, held in the hand and pushed along a flat surface. It will move the cursor in any direction on the screen. Mice come in two basic versions, optical and mechanical. Buttons on the housing allow the user to select a command from a displayed menu, for example, or determine the end point of a line drawn on the screen.
Devices often used as controllers for games and graphics include thumbwheels, joysticks and trackballs. Thumbwheels, which move the cursor in either direction along one axis, are used in pairs to propel the cursor in as many as eight directions. Newer digital models maneuver it in any direction, as do analog joysticks and trackballs.
A cursor's position at the end of a move depends on whether or not the controller's range of motion bears an absolute correspondence to the area of the screen. With an absolute joystick, for example, moving the stick to its lower left position moves the cursor to the screen's lower left. With a so-called rate joystick, however, pushing the stick to the left moves the cursor to the left of where it was, but not to a particular spot on the screen. Absolute devices are thus more effective for rapid, gross movement of the cursor, rate devices give finer control. Some devices can be switched from one mode to the other.
Numerous innovations for computer input devices have been provided in the prior art that are adapted to be used. Even though these innovations may be suitable for the specific individual purposes to which they address, they would not be suitable for the purposes of the present invention as heretofore described.
Summary of the Invention
Accordingly, it is an object of the present invention to provide a computer input device which avoids the disadvantages of the prior art.
More particularly, it is an object of the present invention to provide a computer input device which uses a palm pad in place of a traditional joystick, avoids user pain in the arm that occurs when using a joystick. When the input device of the present invention is used for extended periods of time uses of the housing are so shaped to avoid the need for gripping, requires only a minimal amount of pressure to operate the palm pad, and readily adaptable for use by the handicapped, used to replace the mouse input device. Much less space is required for the present invention.
The present invention is a device used to control computer games or can be used as another type of input device for a computer. The present invention utilizes the action in the palm of the hand for control. This is done through the use of a small plastic case measuring approximately four to four and one-half inches square by three inches high. The case has a spring-loaded plastic palm pad that is connected to contacts inside the device to provide computer signals via an output port with wires to the computer. Rubber suction cups on the bottom of the device hold it steady and in place. A "firing button" is placed on the front of the device for use by the forefinger. This alleviates the muscle strain that occurs using a typical joystick.

Detailed Description of the Preferred Embodiment
The present invention involves modification to a joystick. The stick of the joystick, is replaced with a palm pad, yet still retaining the same functions. The interior electronic components can remain the same or can be modified.
The mechanical components are to be changed as is the present invention. This would improve the life of the present invention.
The present invention involves cutting the joy stick down to a stub, and affixing the palm pad on the stub of the old joystick. The palm pad cup interior is hollow and allows for fit of a coil spring.
The lip encircling the palm pad cup retains the palm pad cup within the box-like housing while holding the components.
The coil spring is used to hold the palm pad above the electronic components inside the palm pad cup.
The palm pad is mounted on a traditional joystick post (stub) and using the same interior as the joystick.
The pain developed in the arm from extensive use of a joystick is caused by a form of tendenitis. Medical doctors have stated that a cure for this form of tendenitis is to reduce or eliminate the use of the joystick.
