Kansei Colour Concepts to Improve Effective Colour Selection in Designing Human Computer Interfaces
Colours have a major impact on Human Computer Interaction. Although there is a very thin line between appropriate and inappropriate use of colours, if used properly, colours can be a powerful tool to improve the usefulness of a computer interface in a wide variety of areas. Many designers mostly consider the physical aspect of the colour and tend to forget that psychological aspect of colour exists. However the findings of this study confirm that the psychological aspect or the affective dimension of colour also plays an important role in colour Interface design towards user satisfaction. Using Kansei Engineering principles the study explores the affective variability of colours and how it can be manipulated to provide better design guidance and solutions. A group of twenty adults from Sri Lanka, age ranging from 30 to 40 took part in the study. Survey was conducted using a Kansei colour questionnaire in normal atmospheric conditions. The results reveal that the affective variability of colours plays an important role in human computer interaction as an influential factor in drawing the user towards or withdrawing from the Interface. Thereby improving or degrading the user satisfaction.
