ERGONOMIC COMPUTER MOUSE WITH HANDHELD AND AMBIDEXTROUS BODY DESIGN

摘要

This invention is an ergonomic computer mouse. The computer mouse body has a unique design in shape that may change the way for people to use a computer mouse. It is designed to be handheld by ring finger, little finger, and the hand part between thumb and index finger with a grip handle. A rear extrusion is smoothly curved and is designed to create a curved support area for the hand part between thumb and index finger. A trackball is confined in the body with a spherical housing and partially exposed on right side and left side of the body. The trackball is arranged near the middle of the body and above the grip handle so that thumb can reach it and operate it in its natural posture. A trackball cover is designed to separate the trackball and hand palm. Two click buttons and scroll wheel are arranged vertically on the fore edge of the body so that index finger and middle finger can naturally reach and operate them. A finger guard ring is designed to help adjusting the body's location in a hand palm with ring finger and little finger. A curved top edge and a front extrusion are designed to make the body shape look aesthetic. Two spherical extrusions on each side of the body are designed to provide 3-points support together with trackball on a flat surface. People can hold and use the mouse at any desired orientation without a flat surface and can use either right hand or left hand to operate it. It can also be used on a flat desk surface (even on a transparent flat surface) as people use a regular computer mouse. It allows people to take a comfortable desired posture to operate the computer mouse and allows people to change hand to operate it. As a result it can reduce discomfort, pain, and fatigue injury on a user's hand, arm, and shoulder when the user works on a computer with this invention.
