11. Computers In the Office Computers, PDAs, networked printers, fax machines, e-mail, cell phones Documents are stored on disk instead of paper Companies have corporate intranets to process online forms PDF (Portable Document Format) files are used to preserve formatting across a variety of platforms in a network or on the Internet Paper is still used for easier reading
12. Telecommuting A work arrangement in which employees work away from the office and communicate with the office using technology
13. Human Factors in the Workplace Ergonomics aims to incorporate comfort, efficiency, and safety into the design of items in the workplace Use an adjustable height chair with 4 to 5 legs A work area of 2 feet by feet is recommended Set the monitor viewing distance to 18 to 28 inches Avoid glare on the screen Keep arms and wrists parallel to the floor Place feet flat on floor or stable footrest Center monitor and keyboard in front of you
14. RSI and CVS A repetitive stress injury (RSI) is caused when muscle groups complete the same repetitive actions over and over again Keyboards and mice are major sources of RSIs Symptoms include stiffness or burning of hands, loss of strength in hands, and pain in the upper back, shoulders, and back Computer Vision Syndrome (CVS) is caused by screen glare, improper lighting, and monitor settings hard on the eyes Symptoms include eyestrain, dry or burning eyes, increased sensitivity to light, blurred vision, headache, and pain in the shoulders, neck, or back
