Pain in your mousing hand, wrist or forearm? Looking for a better way to click? Are footswitches and dwell-click software too cumbersome? We have the solution! Introducing ....the ErgoClick ™

Mouse...without lifting a finger! Have you ever see a concert pianist play with one hand or with the index finger only? Of course not… But we have been working for years with the PC mouse using only the right hand, clicking with our right index finger…. Until now! With the ErgoClick we use both hands in a completely relaxed manner – the right hand (palm only) is used to position the pointer on the screen and the left hand (palm only) to click. People typically grip their mouse too hard as it is required in order to maintain precision while performing clicking actions. The ErgoClick will make any type of mouse better by permitting the user to use a relaxed grip on their mouse, and eliminate finger activity from mousing.

Ergonomic Benefits

Why use the palm? - When you click your mouse (usually with your index finger) you are using the flexor muscles in your hands, which are used to make a fist (or curl your fingers toward the palm). The extensor muscles are used to open your hand, or extend / uncurl your fingers. The average computer user needs to click their mouse (in a typical 8 hour shift) several thousands times in a day. This can lead to the flexor muscles becoming much stronger than the extensor muscles, which will make the muscles in your hands and arms more subject to fatigue and can lead to RSI related injuries including "trigger finger"

What is trigger finger? - Trigger finger involves the tendons and pulleys in the hand that bend the finger. The tendons connect the muscles of the forearm with the bones of the fingers. Each tendon is covered by a slick lining or sheath. When you bend your fingers, the tendons glide back and forth. When the tendon sheath becomes inflamed, it swells and may develop a knot or thickening in the tendon. The knot passes through the sheath as the finger bends, but gets stuck as the finger straightens. This causes further irritation and results in a vicious circle of irritation, swelling, catching and more irritation until finally, the finger locks in a bent position.

How does it work? - The palm of the right hand is used to position the pointer on the screen (1 on the diagram at left) as always with your mouse, trackball or other pointing device. The palm of the left hand is used only to click (2 on the diagram at left). With a slight movement of your palm you can generate clicks and double-clicks (only a single click is needed for Double Click). By using the palm to click rather than the fingers, your hand can maintain a relaxed neutral supported posture, and by simply shifting the orientation of your palm slightly you can generate clicks. This product works best with a compact keyboard to maximize the desktop space immediately in front of the user.

Features

Buttons?: Button 1: Left Click Buttons 2 and 3: Double Click (you only need to click once) Dial 4: Click Force Adjustment Dial (see below)
How hard is the button to press?: The ErgoClick has a unique feature which is not available in any other keyboard or traditional mouse currently on the market – an adjustable clicking force. You can adjust the actuation force of the button from 30 grams to 300 grams, creating as light or as strong a touch as required. Even at the lightest force setting of 30 grams, the click sensation provided is highly tactile and responsive.
Is it practical?: Yes! Traditionally instruments, machines, utensils or activities required the use of both hands, for example:
- in playing the piano or other musical instruments
- when eating and preparing food
- when handwriting (one hand holds down the paper while the other hand writes)
