Abstract

Pointing devices such as computer mouse are commonly used for making selections on computer screens. However, prolong or frequent use of such pointing devices might result in users suffering from repetitive stress disorder. Further, due to the widespread use of personal computers (PC), this problem is made more even pronounced. In addition, users increasingly require additional buttons to be provided on the computer mouse for purposes such as PC gaming. Although device manufacturers have started building more buttons on existing computer mice, the buttons are typically not ergonomically positioned. An embodiment of the invention describes an ergonomic input device with multi-programmable buttons.

Description

technical field [0001] The invention relates to a human-machine interface device used by a general computer, in particular to a human factor engineering designed mouse with a plurality of programmable button functions. Background technique [0002] A mouse pointing device commonly used by a computer is used to control the movement of a cursor on a computer screen so as to select options on a graphical user interface (GUI). Pointing device use often involves highly repetitive hand and phone movements and positional movements, which can cause certain repetitive stress disorders, such as carpal tunnel syndrome (CTS), especially with frequent and stressful movements and / or positions move. Thus, the structure of the pointing device can stress the user's wrist, hand and fingers, causing uncomfortable frequent and stressful movements and / or positional shifts. [0003] In addition, users suffer from repetitive compression disorders due to the use of pointing devices. Currently, p...
