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.
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
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.”
