RollerMouse is a central pointing device for PC & Mac, which requires only very light movements on the roller bar, allowing the cursor to move around your computer screen with ease.
If you already suffer from wrist, arm, neck or shoulder pain when spending long periods of time working on your computer, it’s possible that RollerMouse will help alleviate your symptoms.
Centrally placed, and in front of your keyboard, RollerMouse is easy to reach, requires no gripping, and reduces the need for wearing and wasteful arm movements.
As well as encouraging a light touch, RollerMouse also invites load-sharing between both hands, and can alleviate RSI inflammation and pain that is often associated with problems such as Carpal Tunnel Syndrome, Tendonitis, De Quervains and many more common conditions.
Even if you don’t have pre-existing pain, RollerMouse is the device that can help keep wear and strain injuries at bay. A relaxed way of working is key.
RollerMouse encourages good posture, and whether you are sitting or standing, avoids the need for awkward reaching and leaning, which is often the case with a traditional computer mouse.
As you become familiar with the controls of RollerMouse, it means you no longer need to reach, stretch, or twist to control the cursor on your computer. RollerMouse encourages you position your arms in a naturally relaxed position, in front of your body, rather than out to the side, removing strain to shoulders, arms and elbows.
There is no need for awkward gripping either, as the wide roller bar design allows for finger-tip control, in a way that is comfortable for you, also reducing strain on the fingers, hands and wrists.
With the option of integrated or extended wrist rests, you can find the RollerMouse that is perfect for your needs.
RollerMouse is efficient. The central positioning of RollerMouse means that your hands are always in a natural position over the roller bar and mouse buttons, doing away with the need to constantly look away from your monitor as you work.
With a downward push, the bar provides a mouse click, allowing easy movement of files and folders around the screen. A double-click button makes it easier to open files, or start new programs, without harmful repetition.
You can easily change your cursor speed to suit the work that you do, or the multi-monitor configuration that you have. In addition to this, an integrated scroll-wheel makes it easy for you to move up and down documents or websites. Dedicated copy & paste buttons make light work of repetitive tasks, and you don’t like the button pre-sets, you can decide on your own favourites instead.
With the smallest of hand movements, RollerMouse will allow you to quickly move your cursor, exactly where you need it to be.
RollerMouse. Reduce pain, avoid strain & work faster.
Better movement. You can move the computer’s cursor using both hands. This helps avoid discomfort and prevent pain by allowing you to vary your position.
In the zone. RollerMouse is placed in the middle of your recommended work zone, eliminating long and repetitive reaching movements.
Less demanding. RollerMouse does not require your back, neck, and shoulders to be involved in mouse work.
No grip. It is stationary and grip-less, reducing static and tense positions.
Supportive. Built-in, adjustable wrist supports help you avoid resting your weight on your wrists, reducing stress and strain.
Less strain, more gain. Keep both hands in front of your body. This is the most relaxed position because you use the fewest muscles and tense up the least. You no longer have to reach, stretch, or twist to control the mouse.
A natural movement. Control the cursor and click lightly with your fingers. The traditional mouse forces the body to use large muscle groups (neck, shoulders , and arms) to carry out micro movements.
Less is more. Reduce the number of unnecessary movements. There’s no need to reach to the side all the time, everything you need to control your computer is placed in front of you.
Two hands are better than one. Avoid discomfort and pain by varying your working position. RollerMouse places cursor control in the rollerbar, giving you the freedom to use both hands.
Safe and quick. Double click with a single movement. This saves the body from making thousands of unnecessary and harmful micromovements each day.
Researchers at Harvard University have found that the RollerMouse device significantly improved the posture of the hand, wrist, and shoulder compared to a conventional mouse, while performing tasks at a computer workstation. The study compared the RollerMouse to a conventional mouse, trackball and touchpad; it was determined that the RollerMouse had the greatest effect in reducing muscle effort in the forearm. Subjects also reported the RollerMouse to be easy to use with the least discomfort while performing tasks.
Abstract (taken from the report, presented at Applied Ergonomic Conference 2013, March 19, 2013):
The goal of this study was to evaluate the effect of different types of computer pointing devices and placements on posture and muscle activity of the hand and arm. A repeated measures laboratory study with 12 adults (6 males 6 females) was performed where participants completed two mouse-intensive tasks while using a generic mouse, a trackball, a stand-alone touchpad, and a roller-mouse. An optical motion analysis system and an electromyography system monitored right upper extremity postures and muscle activity respectively.
Roller-mouse associated with a more neutral hand posture (including lower inter-fingertip spread, finger extension) along with significantly lower forearm extensor muscle activity. Centrally located pointing devices (the touchpad and the roller-mouse) were associated with significantly more neutral shoulder postures and reduced ulnar deviation. In addition, significantly lower forearm extensor muscle activities were observed for these two devices.
Despite being unfamiliar with the device, users reported that the roller-mouse was not more difficult to use than the other devices. These results show that both device design and location illicit significantly different postures and forearm muscle activities during use; and suggest that hand posture metrics may be important when critically evaluating pointing devices and their association with musculoskeletal disorders.

Either at work or at home, we are spending more time in front of computers, and often develop habits that can cause stress, strain, and injury.
