Sexual discomfort, erg〇n〇mic engineer plays a key role in the design planning of the VDT phase. The computer workstation is designed to reduce the hazards of work and is measured by human measurements. The interface of the user interface, the relevant parameters used in the design of the computer workstation are as follows: 1. Working surface height: The working aspect is generally based on the user's sitting position, and the scholar 15 research indicates that the user adopts a relaxed posture. The upper arm and the elbow are about 9 degrees to carry out the VDT operation, which helps to maintain the integrity of the wrist and position the hand for the best comfort. Currently, the height of the working surface of the computer workstation recommended by each research unit is based on the elbow height. Make set standards. 2. Screen orientation: The screen is twice the vertical distance from the center of the computer screen to the floor. The position of the screen must be at least 15 degrees below the line of sight. The upper edge of the screen must be lower than the eye level, with an adjustable work table or The screen is better. When the VDT operation is known, the viewing distance of the user's eyes to the center of the screen can be defined as the viewing distance. For the VDT operation, the viewing distance of 5 cm is more likely to produce vision than the viewing distance of 1305815 i〇〇 cm. Fatigue, the line of sight should be adjusted according to the size of the screen and the VDT best line of sight should be set between 51 and 99 cm. If the subject is facing the screen and the arm is straight, the distance of one arm is the most. Good sight. The line of sight angle (line_of_sightangle) is the angle between the horizontal intensity of the eye 5 and the line connecting the eye to the center of the screen. The position of the computer screen should be between 15 and 25 degrees below the horizontal line of the eye, and the line of sight angle is at least 30 degrees, and The screen and the line of sight are preferably 9 degrees, that is, the front of the screen should be slightly up. The VD T related research indicates that the line-of-sight angle i is defined as a high-monitor position (HMP) and a line angle of 30 degrees is defined as a low-screen position (i〇w_m〇nit〇rp〇siti). 〇n; the following is called LMP), HMP in the neck and shoulder EMG (Eiectr〇myogram; hereinafter referred to as EMG) reaction value is significantly lower than LMP, showing the difference in eye and neck and shoulder response, 15 degrees cone in the line of sight Within the scope, the eyeball can be easily rotated. In addition, the study also pointed out that in the case of LMP, the eyelid covers more parts of the eye I5 ball, which can reduce the dryness of the eye. Therefore, the study suggests LMp, but most of it is for musculoskeletal. It is recommended that HMp be preferred. 3. Working surface: The area setting of the working surface depends on the difference between the objects and work types that the VDT user may display (for example, VDT work for writing and flipping data). 2) Design the appropriate working surface to accommodate writing. The size of the equipment, the writing space, and the location of the book, as well as the size of the screen, the printer, and the main unit are also included in the space a planning. The layout of the work surface must be compatible with different types of VDT operations, and the computer peripherals that may be used are planned. Therefore, the design must be matched with the work type to achieve the best results. 4·Screen size: 5: The surface area of the sensory is increased, and the volume of the eye is too large: it is easy for the user to cause the shoulder muscles to be vigorously operated, and the screen is too small but VDT is allowed.
