ICT in society

1
ICT in society

• How ICT affects businesses, consumers employees

2
You need to be able to explain the benefits and
drawbacks of the use of information and
communication technology in

• manufacturing,
• business,
• medicine,
• the home,
• leisure
• education
• tele-working.

3
To what extent has machinery displaced workers?

• Arguments for?

• Arguments against?

Have more jobs have been created by the new
technology (computerisation)? What has happened
to clerical workers over the last 20 years? How
have their skills been lost/changed?
4
Impact of ICT where we live/work

• Call Centres
• Consider British Airways, Insurance Companies,
  Banks etc all who use call centres, but, where
  are these centres?

5
What is Tele-working?

• What are the benefits of Tele-working?
• Consider environment, commuting, working hours,
  commitments, space saving, team-working in a
  network.
• What are the problems with Tele-working?
• Consider management, organisational loyalty,
  social isolation, separation of work with leisure
  time.

6
Consumer issues

• What are some of the new ICT products available
  now?

Addidas store virtual mirrors
A super tablet E-ink
7
Consumer issues

• What new products are on the way?

Not just shoes but clothes
8
New Projector system?

• The EyeMove PC combines the functionality of a
  digital projector and computer into one
  circular-shaped device. Simply hang it on your
  wall or place it flat on a desk and project
  games, movies, or applications.

9
Transparent Toaster

• This innovative concept uses special heating
  glass to warm a single slice of bread.
  Unfortunately, the glass does not reach a high
  enough temperature at this time to actually
  toast the bread. No word yet on if this concept
  will go into production

10
New Batteries

• Two-thirds of mobile and personal digital
  assistant owners said two days' active battery
  life was vital.
• The report said that poor battery life on mobile
  devices was one of the main reasons people did
  not play more games, music and video on their
  devices more often.

11
IT in Banking

• How is IT used in Banking?
• telephone banking, Internet banking, ATMs, Debit
  cards, Credit cards, MICR (Magnetic Ink Character
  Recognition) e.g. cheque processing, Direct
  debiting, etc.
• Paying in cheques scanning

M.I.C.R Magnetic ink character recognition
12
What are the issues of IT in Banking

• Cloning cards
• Fraud
• E-scams
• Consumer confidence

13
E-commerce Virtual stores?

• A virtual store is a web page that hosts
  several stores on one website address. The
  store owners do not want to set up maintain
  their own web-pages and so employ a host to
  manage and maintain the virtual shop for them!
• Web sites used for advertising have been
  developed into a virtual store.

14
Internet shopping

• What are the advantages for the shop?

• What are the advantages for the customer?

What are the implication?
15
How does IT improve home shopping?

• What products can take advantage of INTERNET
  shopping?
• Which products are very difficult to sell on
  line?

16
What issues within Internet shopping will
increase its use?

• The ability to arrange delivery outside work
  hours eg in the evening or weekend is an
  important factor.
• Broadband access has speeded up the process of
  selecting and ordering item on web sites

17
How are computers used in manufacturing?

• What is CAD?
• Computer aided Design
• What is CAM?
• Computer aided manufacture

18
C.A.D. in restaurants
So why is it important for a restaurant to
carefully consider its layout?
19
More C.A.D images
20
CAD

• How can a computer image help with design?
• How does CAD enhance sales and marketing?
• What is the difference between Vector based
  graphics and Bit-mapped graphics?

21
Vector V Bitmap images!
22
Bitmap images
A bitmap image is quite literally a collection of
squares that, taken together, make up the image.
The squares might be of different colors, but
they are all the same size. Because a bitmap
image is this collection of squares, it doesn't
hold up well to expansion
23
Vector images

• the vector image's parts are scalable.
• This means that designers can change the
  resolution of a vector image in both directions,
  making a high-res image lower or making a low-res
  image higher.
• If designers are looking for an image that can be
  easily scaled in both directions, then their
  choice between vector and bitmap should be an
  easy one.

24
Spot the difference in a Vector?
25
Spot the difference with a bitmap image?
26
CAM - basic components
An actuator is mechanical device for moving or
controlling something. They are used in the
computer control of an environment, industrial
automation and in robotics.

• CAM uses Robotics which require the following
  parts
• a sensor,
• a microprocessor,
• an actuator.

27
Actuators
28
Why are robots so useful?

• Give some examples of where robotics are used?
• Consider
• repetition,
• strength,
• quality,
• costs,
• hazardous environment.
