ERGONOMICS

Ergonomics is a science whose main purpose is to design workspaces and tools that

help people do their jobs and use their tools and other products comfortably and safely.

Ergonomics uses knowledge of human abilities and limitations to design systems,

organizations, jobs, machines, tools, and consumer products for safe, efficient, and

comfortable human use. Ergonomics helps to make the best use of human and

technical resources through optimizing the application of existing and new technology to

the benefit of users and environment. Its applications enhance job satisfaction,

productivity and maximize the product or system quality by improving usability. he

importance of arranging a workstation in a healthy way has already been stated in old

records dating back to the !"th #entury. $n old %atin quote notes that &the maladies

that afflict the clerks arise from three causes' first, constant sitting, secondly the

incessant movement of the hand always in the same direction and thirdly the strain on

the mind from the effort to not disfigure the books by errors.& Ergonomics is the study of

understanding the limitations of the human body in order to design productive and

comfortable workplaces, tools and work tasks. (e study what postures are comfortable

for computer work and what are not.

COMPUTER ERGONOMICS#omputer Ergonomics is about things that you can do to make working on a computer

more comfortable and better for your body. )or example, wearing a bike helmet when

riding a bike and a seatbelt when riding in a car are two simple things that you do to be

safe.

Computer Ergonomics is also called as the HUMAN COMPUTER INTERACTION

!HCI" or MANMACHINE INTERACTION !MMI"# *uman+computer interaction is a

discipline concerned with the design, evaluation and implementation of interactive

computing systems for human use and with the study of major phenomena surrounding

them. he basic goal of *#I is to improve the interactions between users and

computers by making computers more usableand receptive to the users needs.

he study of ergonomics is applied in the workplaces where computers are used in

large numbers and for large durations in a day because it is very essential to design the

#omputer related injuries are increasing with the explosion of computer technology in

the workplace. -rolonged and repetitive work at your computer workstation can create

discomfort, muscle aches, and be the cause of work related injuries. Improper posture

and improper body positioning at your computer workstation can cause or exaggerate

the problems. $s we use computers for longer hours every day, we may notice

increasing aches and pains in some parts of our bodies. hese musculoskeletal

problems can happen in anyone who uses a computer for long hours' computer

programmers, engineers, data entry workers, telephone operators, customer service

workers, and even graduate students. he problems can range from minor muscle

aches that last less than a few hours to persistent tendon problems that can last for

years. he more severe problems can lead people to leave a job they like or stop doing

sports activities they enjoy, like tennis or bicycle riding. /o one should do what they can

to prevent the minor aches of work from progressing to disabling conditions. he most

common body areas to watch for are the hands, wrists, elbows, shoulders and neck.

he problems may vary from aches to pain, burning, numbness or tingling. hesesymptoms may be felt during typing or mouse use or at other times when no work is

being done, including during the night when the symptoms might wake you up.

he research on computer ergonomics is important for the working individual as well as

for the employer who is interested in limiting absenteeism, and in increasing worker

productivity.

Importance of Ergonomics in ;esigninga (orkplace for #omputers

=usculoskeletal disorders 6=/;s7, a superset of repetitive strain injuries 65/Is7, are a

mammoth cause of

medical costs, lost work time and reduced productivity. his issue affects both

companies and

employees. >overnment bodies that track such statistics consistently show that the

problem is significant. /ince these injuries develop slowly over time, they can be muchmore difficult to identify than an injury that is attributable to a single traumatic event. $s

a result, people tend to neglect the warning signs and work through the pain, unaware

that they may be suffering significant injury. =eanwhile, the damage continues to

accumulate. (orse, these injuries can be very costly and difficult to treat once they

develop into a full =/;. It is often much easier to address these problems early than it

is to treat them after they have become full+blown disorders. $s the severity and depth

of these problems grow and begin to draw public attention, more emphasis is being

placed on the science aimed at studying and addressing these work+related problems'

ergonomics. Ergonomics is an applied science aimed at studying peoples physical

patterns of work and helping improve them. Ergonomics seeks to make a better match

between workers physical capabilities and their work environment and activities. his

can be accomplished through better design and operation of tools, workstations,

equipment and controls. Ergonomically designed products have been appearing in a

variety of industries in response to the increasingly visible problems addressed by

ergonomics. Ergonomically designed office furniture, luggage, garden tools and

computer products are growing in popularity. In the area of computer input, ergonomics

is aimed at maximizing productivity by reducing worker fatigue and discomfort, reducing

errors, and increasing input speed. ?y applying the principles of ergonomics to the

design of workplace tools such as keyboards and mice, =icrosoft and other companies

are able to make products more comfortable and worker+friendly, particularly during

periods of extended use.

he keyboard is a crucial component of a properly designed computer workstation.

computer users from different occupations, " percent of females and "D percent of

males reported that they were experiencing at least one musculoskeletal symptom.

$ddressing these symptoms before they become full+blown injuries is very important

because it is generally much easier to prevent 5/Is than it is to treat them. )or this

reason, effective ergonomic programs are extremely important. o help deliver on an

important component of effective ergonomic programs, =icrosoft has developed

numerous input devices designed for comfort. he =icrosoft 3atural line of keyboards,

launched in !AAB, has become the 3o. ! best+selling ergonomic keyboard design of all

time.!! In fact, this fixed alternative keyboard design has been shown to reduce wrist

and carpal tunnel syndrome symptoms. )ollowing on the success of the 3atural

9eyboard design, =icrosoft now offers two new ergonomic keyboard designs.

)irst, the advanced 3atural 9eyboard, 3atural Ergonomic 9eyboard BCCC, offers a

breakthrough in ergonomic design that builds on the design principles used in the

original 3atural keyboard design. /econd, the #omfort #urve design offers an easy+to+

approach design, providing a greater comfort benefit that is more accessible toeveryone, especially those who prefer a flat keyboard design. =icrosoft also has

developed a comfortable line of mice by focusing on providing proper contact area with

the hand. 1sing these devices as part of a solid ergonomics program can lead to a

reduction in the instance of repetitive strain injury. $ recent study demonstrated the

injury+prevention benefits of using the fixed alternative design of the =icrosoft 3atural

9eyboard over time, concluding that, FIn terms of primary prevention, only the fixed

alternative keyboard demonstrated a significant effect on the incidence of

musculoskeletal symptoms.G In turn, this reduction in 5/I risk can lead to dramatic cost

savings H over "CC,CCC per year based on the hypothetical example of !C percent

injury reduction in a JCC+person company.

Implementing a strong ergonomics program based on ergonomically designed mice and

keyboards H such as those offered by =icrosoft H can result in many advantages and

cost savings that not only boost employee morale and engagement, but bolster the

bottom line as well.
