Transcript of Computer Ergonomics
of... but have you ever thought... COMPUTER ERGONOMICS Ever since we learnt how to press a button, hours and hours have been spent infront of the computer Posture ergonomics explains... the very heavy radio stars, whose gravitational field is so strong that even light can't escape from them. that's why they are 'invisible' The theory of general relativity predicts that a sufficiently compact mass will deform spacetime to form a black hole. Computer ergonomics is the study and science of the design and safety of computer equipment which are used in our daily lives. THANK YOU FOR YOUR COOPERATION! :D To the wise old age.. THE NECK Incorrect THE BACK Incorrect Correct Correct THE WRISTS Correct Incorrect THE LEGS Incorrect Correct Equipment ADJUSTABLE CHAIRS LCD MONITOR KEYBOARD ARM RESTS THE EYES Incorrect Correct Environment WINDOWS The monitor should not face any windows which would make the screen reflect light.
This would have a negative impact on your eyes. LIGHTING Computers should be used in a well lit room.
Bad lighting also has a negative impact on your eyes.
Good lighting can reduce eye fatigue and headaches. RECOMMENDATIONS ? Try to spend atleast 5 minutes away from the computer every hour
Stretch to the point of MILD tension
Incooperate the stretches into your daily routines
Use ergonomic equipment
Try to use an ergonomic workspace
Make sure the screen is not facing a window
Use the computer in adequate lighting
Make sure there are no trailing wires SURVEY In order to find out whether students follow basic ergonomic procedure, mainly POSTURE
The survey was carried out at school level
Primary school students were mainly observed The Graph shows the results of the survey... A good chair provides necessary support to the back, legs, buttocks, and arms, while reducing exposures to awkward postures, contact stress, and forceful exertions. Thin flat panel monitors and adjustable monitors have advantages over standard Cathode Ray Tube monitors. Lets you tilt the keyboard away from you slightly for better posture (negative tilt), and allows you to use the mouse with your upper arms relaxed and as close to the body as possible. COMPUTER VISION SYNDROME Occurs when your eyes get tired from intense use Caused by:
Extended use of a computer or video monitor.
Exposure to bright light or glare
Straining to see in very dim light Repetitive strain injury Condition where pain and other symptoms occur in an area of the body which has done repetitive tasks . Also associated with upper limb disorders consequences.. Center for Higher Secondary Education Schools' Health Assembly 2012 Rewiring Health Ahmed Shaffan Mohamed Imaan Ahmed Ismail Aishath Zindh Waleed Hafeeza Ibrahim Dheena Ahmed Shareef Hassan Azzan While the spine can maintain a natural curvature without lower back support provided by the seatback, the natural tendency for most people when sitting for a long period is to slouch forward. This slouching posture pushes the lower back out, so that the natural inward curve goes in the opposite direction—outward toward the chair—straining the structures in the lower back. IMPORTANCE OF LUMBAR SUPPORT Every few minutes look away from the screen for a few seconds.
Focus your vision on distant objects.
Blink serveral times.
Use the palms of your hands place gentle pressure on closed eyes for 15 - 30 seconds. Exercises for the Eye Myopia A condition of the eye where the light that comes in does not directly focus on the retina but in front of it. This causes the image that one sees when looking at a distant object to be out of focus but in focus when looking at a close object. KEEP SMILING! =D
