Abstract: The ultra ergonomic computer mouse includes an angled grip-rod which, when held and placed in the correct manner, supports and influences all the fingers and the hand to be in a naturally curved position. It also includes a contoured and grooved rubber foundation, which is shaped in such a way that the hand holding this mouse is put in a natural position and is greatly supported In this way, the user of this mouse would not be required to twist or in some way contort the hand, wrist, or forearm Therefore, the ultra ergonomic mouse especially prevents and/or reduces fatigue, discomfort, and pain despite continuous use over long periods of time.
