Modern shopping

Online shopping has become much more common:

Supermarkets (e.g. Tesco)

High Street retailers (e.g. Next)

Internet only retailers (e.g. Amazon)

Online Auction sites (e.g. eBay)

Travel companies (e.g. First Choice)

Insurance companies (e.g. Direct Line)

Government services (e.g. Car Tax)

Why do retailers offer their goods on line?

reach a larger number of customers

store more products in warehouses

smaller retailers can compete

lower costs

stay open 24hrs

customer tracking

Future homes

Modern homes are becoming increasingly
computerised
. This fridge has a screen for

TV and Internet viewing. It can keep track of
the goods in your fridge and let you know
when you need to order more groceries.

Other applications where computers are
becoming increasingly used include:

home security

home entertainment

healthcare

Some forecasters think that future smart homes will

include scanners that will link to healthcare software
and monitor our general wellbeing.

Expert systems are computer
systems that try to “think” as a
human expert would.

They have a huge
database

of stored information and a
set of
rules

that apply to it.

By following rules, they can give
out the most appropriate advice.

Modern healthcare

Many people use the
NHS direct

website, which uses
expert
systems

to help diagnose people and save doctors’ time.

Modern surgery concentrates
on making the smallest
wound possible to reduce
damage to the body.

This is called
microsurgery
.

Thin
robotic

arms are fitted
with surgical instruments. They
reduce hand tremors and allow
tiny incisions, which speeds up
healing.

Telesurgery

In 2001, a surgeon
in the USA operated
on a patient in
France


the first

telesurgery
.

Special controllers provided sensory feedback
as the patient was operated upon, and the
use of dual cameras provided the surgeon
with a 3D view. At all times the surgeon in the
USA and the team in Paris kept in close
contact with audio and video links.

3D imaging

Doctors can use 3D images of their patients to
see the shapes of tumours and to practise in
advance of surgery.

Before this technology was available,
doctors could only rely on x
-
rays, which

did not always provide enough information.

By using a number of different types of
scans and building up a 3D model,
doctors can pinpoint the exact areas
where surgery is needed. This increases
the chances of a successful operation.

And beyond…?

Technology is increasing at such a rapid rate that it is hard to

predict what the future will look like. However, some trends

are already appearing:

Conversion

of functions into single devices (e.g. the TV,
computer, recorder, music centre and games console are
replaced by one single device)

Faster

data transfer and
more

data storage (allowing for
cheap video calls and more powerful online services)

More time spent online

and the potential of truly
virtual
worlds

with accessible virtual reality technology

Increased processor power

and more complex
programming resulting in faster, ‘smarter’ computers.

Some futurists suggest one day there will be
artificial
intelligence

or even a
technological singularity
.
