A better way to work
The traditional mouse forces you to use your arms, back, shoulders, neck, hands, and wrists to perform a simple task – moving the cursor on a computer screen. This is the root of many potential problems, from repetitive strain injuries such as Carpal Tunnel to Tendonitis or simply causing pain.
RollerMouse is an ergonomic alternative to the traditional mouse that sits directly in front of your keyboard. You move the cursor by touching the rollerbar lightly with your fingertips. RollerMouse eliminates harmful movements and helps form safer working habits.
Our approach is simple:
a. Eliminate unnecessary movements.
b. Make required movements as precise, comfortable, and effortless as possible.
c. Every movement is made from a central position.
Our products are designed for you, and the way you were meant to work.
Why RollerMouse is a better way to work
You can move the cursor using both hands. This helps avoid discomfort and prevent pain by varying your position.
It is placed in the middle of the recommended work zone, eliminating long and repetitive reaching movements.
Does not require your back, neck, and shoulders to be involved in mouse work.
It is stationary and grip-less, reducing static and tense positions.
Built-in wrist supports helps you avoid resting your weight on your wrists, reducing stress and strain.
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.
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.
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.
Avoid discomfort and pain by varying your working position. RollerMouse places cursor control in the rollerbar, giving you the freedom to use both hands.
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.

As part of a year-long effort to collect data on processes that affect overall production, an internal study was recently performed within the account processing department of a major Fortune 500 business services company, investigated the effect of using the RollerMouse on the daily production rate of account processors. A total of twenty-four active account processors served as the subject group. Subjects were provided the same skilling for the prior 30 days, and contained different skill sets.
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.
