Ergonomics and health issues
Lack of physical activity
obesity
hypertension (high blood pressure)
diabetes
increased risk of heart disease.
Repetitive Strain Injury (RSI)
Carpal tunnel syndrome (CTS)

Ergonomics and health issues
Repetitive Strain Injury (RSI)
A class of injuries (to tendons, etc.) caused by
repetitive actions.
Carpal tunnel syndrome (CTS)
CTS is caused by inflammation of the tendons in
the wrist.
Ergonomics
Refers to the study and design of workplace for
comfort and safety of people in work
environments.
5
Ergonomics and health issues
Keyboards
to promote a more natural position for hands and
wrists, with the palms turned slightly toward
each other rather than flat relative to the
keyboard..
6
Ergonomics and health issues
Mice
Used extensively in a GUI environment and
requires users to hold their hands in unnatural,
awkward positions for long periods of time.
7
Ergonomics and health issues
Healthy practices

• Sit correctly

• Adjust the height of your seat or table

• Adequate ventilation/air circulation

• Mouse and keyboard are on same level, close

• Monitor is positioned at the correct level

• Prevent eye strain

• Take regular breaks

8
The need for green computing
Energy efficiency- problem
9
The need for green computing
Energy efficiency- ways to improve
10
The need for green computing
reduce toxins in technology manufacture
E-waste
force re-cycling of e-waste
11
The need for green computing
Paperless office?
Paper
12
The need for green computing
Paperless?

• Small portable devices with high quality
  displays and
• long battery lives only arrived recently

• Digital Divide these devices not affordable
  enough

• Hard copy is the cheapest and easiest way at
  moment

• Paper cheaper and less risky than
• large visible video displays

• Hard copies - non-electronic
• backups of data/information

13
The need for green computing
Tips on how to practice green computing

• Switch off computers and devices you are not
  using

• Try and avoid the senseless wasting of paper

• Try and upgrade or give away old hardware, not
• throw away

• Send old ink cartridges back to manufacturer

• Refill and reuse old ink cartridges
