Introduction

Definition…

Interface Problems

• Difference • Language

Human Factors

• Physical environment

• Health issues

• Use of colour 

physical environment & health issues

• physical position• temperature • lighting• noise • time  

Colours

• Colours• Colour vision Rods Cones

CRT screen

Colour Principles &Guidelines

• bright colour in the foreground

• best background * black*• worst * brown or green*• limit colour to eight • avoid saturated blues for

text• choose with care• Ensure colours differ in

lightness

Web design

Should be designed in shades of gray,

black and white.Reasons for above

statement:• Some type of color

deficiency. • Age factor . • Monochrome monitors.

Guidelines based on properties of color

Murch discussed screen color use based on the properties

of the eyes, discussing distribution of rods and

cones.

Uses of color by Schaeffer

and Bateman

They discuss colors in terms of:

• Affective uses.• Structural uses.• Cognitive uses.

Use of color by Pett and Wilson

• Add reality.• discriminate elements of a visual.• to highlight main points. • highly saturated colors for materials

intended for young children.• red ,yellow and green color have

specific meaning in traffic lights.• Example blue color.

GUI( graphical user interface)

• Definition.• Uses.• Common features.• Control.

Design

Interaction DesignInteraction design principles• Familarity• Human factor• Standards • Feedback

HCI Design Approaches

There are four basic design approaches

• Anthropomorphic ApproachAffordanceConstraints

• Cognitive approachMetaphoric design Human information processing

Model

Contd.

• Empirical ApproachHuman task performance

MeasuresA/B testing

• Predictive Modeling Approach

Design Process

Working in multidisciplinaire teams

• Many people from different backgrounds involved.more ideas and designs

generated.difficult to communicate and

progress forward the designs being create.

Hci and children

• Use of computer technologies

• Interaction design• Négative affect• Design méthodologies• Design principle

The past of Hci

• 1970,Alon Kay an engineer• Formed Xerox PARC( Palo alto

research centre)• Produced Xerox Alto Desktop

Computer in 1973• Don Massaro in 1976• Concept of personal computer for

office called Star• Innovations and validation in Hci

The Present of Hci

• PCs• Office , home, médical and

mobile• Cellphones• 800 million units, four times

annual sales of PCs• Smart phones• Running at 100million units• Internet and softwares• Wireless Keyboards and

remote controls

The Future of Hci

• Computing (WIMP)• Application design• Speech recognition (micro phone and

speakers)• In 2020, computer anticipation(what we

want)• Development of technologies over next

decade, better reflect human values• Drift table, piece of furniture allow people to

view photography of their local neighbourhood and beyond

• Smart devices will replace by tablet computers and speech recognition systems

Saying of Bill Buxton

Microsoft researcher

“It is about how we anticipate the uses of technology rather than being reactive. Currently human is not considered part

Of process.”
