Define HCI and what it involves

Evaluate the development of:

· Sense Orientation

· Graphical

· Speech and Touch

Evaluate the development in user interaction in the following: -

· Hardware

· Screens

· Pointing devices

· Speech recognition/voice control

· Biometrics

· 3D interfaces

· Virtual Reality and Augmented Reality

· Artificial Intelligence systems

Evaluate how the interaction between the computer system and the user is affected by: -

· Types of Users: -

· Expert users

· Regular users

· Occasional users

· Beginner/novice users

· Ergonomics

· Health & safety

· Demographics: -

· Age

· Education

· Cultural issues

· Globalisation

· Local information systems

Accessibility features that can be used to support a user 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.

Explain the Impact HCI has on: -

· Usability of Systems

· Social interaction

· Working patterns and styles on commerce economies

· Assistive technologies in screen magnifiers

Explain the use and implications of design Principles in HCI: -

· difference between recognition and recall

· screen design for intuitive data entry

· menu selection

· perception:

· Gestalt laws of perception

· Colour (include trichromatic and luminance)

· Gross 3D shapes

Explain Schneiderman’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.

Evaluate behavioural models: -

· keystroke level model

· Throughput (TP)

· Fitt’s Law

· Key-action-model (KAM)

· Buxton's three state model

· Guard's model of bimanual skill
