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 Design Interaction design principles Familarity Human factor Standards Feedback

HCI Design Approaches There are four basic design approaches Anthropomorphic Approach Affordance Constraints Cognitive approach Metaphoric design Human information processing Model

Contd. Empirical Approach Human task performance Measures A/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.

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.”
