Factors to be taken into account when designing a good HCI

Year 13Slide2

Lesson Objectives

To understand the factors to be taken into account when designing a good HCI.Slide3

The factors…

Consistency of signposting and pop up information

Clear

navigational

structure

Layout

appropriate to the

task

Customisable

to suit the needs of the

user

Location

of where machine is to be used

House

Style/Ethos (Not Consistent Layout)

Specific

point about colour

blindness

On

Screen / online

helpfiles

(built in with software

)

Expertise

of the user/ ability of user / difference between novice and expert user Slide4

Consistency of signposting and pop up information

e.g

. Every ‘Next’ should be in the same place using the same icon. Navigation around the program should be clear consistent and easy to follow. – intuitive, learn fasterSlide5

Clear navigational structure

e.g. It speeds things up if there is a similar route through the programs (if it is clear) as users do not have to keep learning things / Helps users learn their way around the system. Slide6

Layout appropriate to the task

There

should be standard ‘feel’ to software. e.g. Large/minimal text for a child to minimise reading which builds up user confidence./ Bright colour scheme to attract a young child’s attention. Doing a repetitive task such as entering holiday bookings means you have less guidance on the screen.Slide7

Customisable to suit the needs of the user

e.g

. Makes it more efficient if the user can change items to suit their work preference. Slide8

Location of where machine is to be used

e.g

. No sound in a noisy area. Touch screens in museums / factories /

etc

, (with explanation of why). Slide9

House Style/Ethos (Not Consistent Layout)

e.g

. So that it conveys who the organisation is and all the company docs look/feel the same. Slide10

Specific point about colour blindness

e.g

. Design to avoid red/green combination - blue/yellow best combination. Slide11

On Screen / online helpfiles

(built in with software)

e.g

. Rather than wasting time looking in manuals, important if no outside help available when working. / Tool tips telling the user what to do. / interactive user manual that answers general FAQ. No marks if can be read as a Google search.Slide12

Disabled Access

e.g

. If a person is blind then the computer could recognise voice input / Braille keyboard. Slide13

Expertise of the user/ ability of user / difference between novice and expert user

An

expert user will need shortcuts so that the task can be completed as quickly as possible (Command line) whereas a novice will need a number of steps to guide them (GUI).Slide14

Exam Question (Variations)

Other than [user expertise] and [on screen help] describe [4] factors that should be taken into account when designing a good HCI.

A bank is designing a new HCI for its staff. Give [4] examples that they should take into account when designing a good HCI.
