What are computer ergonomics?
Computer ergonomics includes science associated with safe and efficient use of computer equipment. In the 21st century, many jobs include long periods of work with computer monitors, keyboards and other input devices. The poor use of these devices for a longer period of time may result in recurring stress injuries (RSI) and other health problems for workers and to reduce the effectiveness for employers. Computer ergonomics seeks to correct these problems with technical computer devices to meet the needs of the user rather than forcing the user to match the design of the computer. The industrial revolution of the 18th century and the introduction of the assembly line at the beginning of the 20th century contributed to the new working environment. Workers could produce a huge number of items quickly, but soon it was found that the bad design in the workplace contributed to inefficiency and wozdravotní problems RKER. Ergonomics, although not always known under this name, meant that workers could produceSubjects have reduced the need to replace and train employees faster and better and improved health health.
At the end of the 20th century, a similar revolution in technology created millions of computer jobs around the world. Once computers have become efficient and available, these systems have been transported to offices that replaced older technologies such as typewriters. Computers were often placed in old works that otherwise remained unchanged. Soon workers complained about health problems such as eye -head and back or neck problems. The carpal tunnel syndrome, the nerve disorder affecting the wrist and the hand, has expanded due to the constant use of keyboards and computer mice.
Computer ergonomics fields are trying to fight these problems with scientific studies to improve equipment and workplaces. For example, computer ergonomics experts recommend that the screen includesČe should be at the eye level of the worker, located roughly on the length of the arm for comfortable reading and inclined to reduce the glare from the light sources. The keyboard should be centered in front of the user and placed at the elbow level or under the elbow. The mouse should be in a similar position and the user's hand should only rest when the mouse is used. In fact, frequent short breaks from the mouse and keyboard can reduce the chance of RSI, especially in combination with regular stretching exercises.
Some computer devices have been designed with regard to computer ergonomics. The ergonomic keyboard has an angle surface next to a padded pad, which provides user wrist a more natural, relaxed angle to reduce the chances of carpal tunnel syndrome. The ergonomic mouse is also built to allow a more natural position for the wrist and hand; One design is shaped as a pen and removes the need to place it on the wrist on the table. This external device can be added to the laptop for those whoThe ears use this form of hardware as their primary device. Ergonomic chairs, racks and monitor stands provide support back and do not require the neck to be in cramped or extended positions for a long time.
