Abstract:

The optimum design for human-computer interfaces has become an increasingly important concern. Optimization requires interface to match the characteristics of the user with those of the computer system. At present, it is not clear what user characteristics, beyond a limited set related to experience and training, should be considered. This research project addresses this question. Many forms of human-computer interaction can be viewed as problem- solving activities. Therefore, the cognitive characteristics that affect problem-solving performance may also affect problem-solving performance in the context of user interaction with a computer system. The questions addressed in this research program were these 1 How might fundamental, inherent individual difference dimensions of cognitive operations influence interface design 2 What cognitive dimension, beyond experience, is really important to human- computer interaction 3 Aside from the classification of users into expert and novice categories, is a given interface design equally good in supporting the problems solving activity of any particular person Two experiments were conducted. The results revealed that efficiency in using computer systems depends on user cognitive characteristics and design features of computer interface. Further, usage of interface design features significantly interacts with a subjects fundamental cognitive characteristicscognitive style.
