"... While experts predict a steady increase in notebook sales through the end of 2010, consumers often don’t consider the compromises in comfort that are made when using such a computer. Based on academic research and years of manufacturing experience, Ergotron has published a white paper, Comfortable Portable Computing: The Ergonomic Equation, aimed at providing valuable, easy-to-use guidelines to help people achieve comfortable, more productive portable computing.
Using a portable computer improperly can increase one’s risk of future health problems from neuro-musculoskeletal disorders. “The purpose of the white paper is to educate people on the risks associated with portable computing, and to let them know that they don’t have to jeopardize their health and well-being when using a portable,” explained Pete Segar, Senior Vice President of Engineering and CTO of Ergotron. By applying basic principles set forth Ergotron’s “Ergonomic Equation,” anyone can achieve comfortable computing.
The Ergonomic Equation consists of three simple considerations: Neutral Posture, Voluntary Motion and Restorative Time.
First, one must consider Neutral Posture, which is the position the human body assumes naturally and comfortably. It expends the smallest amount of energy and results in the least amount of bodily stress and related fatigue.
The second consideration is Voluntary Motion, which works in conjunction with neutral posture toward maintaining a body in balance with itself and its surroundings. It refers to movements the body makes naturally to prevent strain and fatigue.
Finally, Restorative Time balances stressful activities with restorative activities. These could include a variety of actions, such as a walk to the water fountain, or deep-breathing exercises practiced periodically throughout the day." (Continued via Ergotron) [Ergonomics Resources]
