The question of which type of computer interface is 'better' for different types of users is of great interest to human factors engineers. It is argued that very few valid comparisons have been done on systems whose interfaces have been specifically designed and developed to be functionally identical. This paper covers just one study where such an interface has been developed for an investigation which has looked at the individual subject's psychological, social and environmental differences, and how those differences influence the subjects feelings, performance, and preferences with regard to various computer interaction methods. This paper concentrates on giving a description of the findings on interface preferences and performance.
