Before we had Windows : Command Line Interface (CLI)

What is the point of this CLI?

What would an advantage of a computer interface like this be?

Can you think of any disadvantages?

Next……..

The first GUI (Graphical User Interface)

This is a graphical user interface, we’ve gone from typing commands in, to clicking on icons, this was a big leap forward

……..and then…..

Windows 95

Really starting to think about a user interface now

Good user interfaces should;

be attractive and pleasing to the eye
allow the user to try out different options easily
be easy to use
use suitable colours for key areas
use words that are easy to understand aimed at the type of user
have help documentation

It should also consider the needs of the users. For example, young children are likely to prefer pictures to words and people with disabilities may benefit from particular input or output devices

Which do people prefer and why?

The GUI is more user friendly and intuitive, this is where HCI comes in, a whole science has been built up around building user interfaces, and it’s called Human Computer Interaction or HCI

Can you think of a disadvantage of GUI?

Much more processing power and memory is needed in the device, and more expensive to make and buy

Some questions

Write down (in your own words) three things you found out about Human Computer Interaction.

State an advantage of the Command Line Interface

What is a GUI?

Following the principles of HCI should mean

You end up with a well designed computer interface, (tablet, PC, laptop, smart phone) which;

is attractive and pleasing to the eye
allows the user to try out different options easily
be easy to use
use suitable colours for key areas
use words that are easy to understand aimed at the type of user
have help documentation
It should also consider the needs of the users. For example, young children are likely to prefer pictures to words and people with disabilities may benefit from particular input or output devices.
