What is a computer's adjustable workstation?
The computer's adjustable workstation is one that allows the user to adjust the height and orientation of the chair, keyboard and other input devices and display monitors. It has been shown to allow users to control their workstations to protect their physical health and even increase their productivity. The key feature of the adjustable workstation is that it is constantly adjustable; Repairing different components at certain locations because they are "ideal" based on the user measurement, forcing the user to maintain one position. However, education is a critical requirement because users will sometimes make adjustments that they consider short -term but that could contribute to long -term damage.
Many of the first computer workstations were one -piece terminals for entering data whose keyboards and monitors were part of the same unit. Were often placed on tables or table tops; Sometimes they were screwed into furniture for safety purposes. Thep Chairman was onlyThe device is adjustable by the user, but its adjustability was often limited. Many chairs in the data were on wheels and some were adjustable heights; However, other controls common to modern office chairs were not available, except for very expensive chairs.
Many of those who used these early entry terminals complained of various diseases, from back pain and neck pain for eye pain, headaches and wrist and forearm pain. Studies based on ergonomics - studying job design to adapt to people - showed that users were sometimes forced to sit in unpleasant positions to control keyboards and clearly see monitors. These positions placed unnecessary stress of their muscles, skeletal systems and eyes.
This strain, not relaxed, could lead to damage in the long run. For exampleVillagetes emphasizes the nerves passing through the channel in the wrist called the carpal tunnel. Continued incorrect keyboard can lead to a painful condition called carpal tunnel syndrome.
Studies have found that the optimal position for computer users sits straight with the legs flat on the ground or slightly raised to the adjustable foot. The user's knees should be bent at an angle of 90 degrees and the forearms should also be located at about 90 degrees to the upper arms when the hands rest comfortably on the keyboard without any significant bending on the wrist. The monitor should be at the same height as the user's head or a little lower to see directly forward or slightly down.
As soon as the problems associated with non -evaluable devices are known, it was clear to many that the best solution would be to provide each user with an adjustable computer workstation. This would essentially consist of essentially a separate adjustablepatform for the monitor and Ka keyboard and a completely adjustable chair. Education was also a desirable element of providing adjustable workstations, so users and their employers would know what they are trying to do. For example, it has been found that users should be able to make minor adjustments to their positions more or less continuously to hold a specific position throughout the day.
Some employers resisted the cost of providing each user to provide an adjustable computer workstation. Many people have mocked the statement that the non -consumed workstation could cause long -term injuries and mock research supporting these claims. Some of this resistance was overcome in the US when many carpal tunnel syndrome and some other repeating stress injuries (RSIS) have successfully claimed to compensate workers. Computer workstations and seats are sold separately on a modern market, but if they are integrated, they give users a high level of control of NadjejiceH Own working conditions.
