Vocational Scenario or Context

You have just joined the software development team of Hot Digital Web Development as a trainee software developer.

The company specialises in producing websites for organisations.

You have been asked by the development team to produce a report on HCI principles of technology advancements. This report will need to be presented to the development team

Task 1

The software development team manager has requested that you investigate and consider how developments in technology have changed the way users make use of, and interact with, computer systems and the impact this has on society.

Your report should start with an explanation of the principles of human–computer interaction.

Evaluate how the use of computers has developed from the use of early computers to today’s interactive devices:

· command line interfaces versus graphical user interfaces

· sense orientation, graphical, speech and touch.

The developments in user interaction in these areas:

· hardware

· screens

· pointing devices

· speech recognition / voice control

· biometrics

· 3D interfaces

· virtual and augmented reality

· artificial intelligence systems.

Evaluate how the interaction between the computer system and the user is affected by the type of users, device and needs.

· types of users:

· expert users

· regular users

· occasional users

· beginner/novice users

· ergonomics

· health and safety

· demographics:

· age

· education

· cultural issues

· globalisation

· local information systems.

Provide a section on the accessibility features to support a users’ needs with restricted motor skills.

Evaluate the uses of human–computer interaction in self-checkout systems and ways in which people interact with systems such as a touch screen facility.

The impact of human–computer interaction on:

· usability of systems

· social interaction

· cultural impacts

· working patterns and styles in commerce economies.

· assistive technologies in screen magnifiers.

The use and implications of design principles in human–computer interaction.

· difference between recognition and recall

· screen design for intuitive data entry

· menu selection

· perception:

· gestalt laws of perception

· colour, to include trichromatic system and luminance

· gross 3D shapes.

In the last section of the report you should focus on Shneiderman’s rules of interface design:

· consistency

· use of shortcuts

· informative feedback

· design dialog to yield closure

· error handling

· reversal of actions

· support internal locus of control

· reduce short-term memory load.

The report should conclude with an evaluation of behavioural models such as the keystroke level model,
