Investigations of the effects of different computer input methods on man–computer interaction

The development of interactive man-computer systems is a design process wherein various alternatives must be considered from different points of view. In order to make design decisions, information guidelines are needed. Among the requirements are those for different input methods of computers. This thesis has the objective of providing information and guidelines on how different input methods affect man–computer interaction. The objective is reached through a number of stages: a review of literature; the development of a framework for investigation; deriving and testing experimental hypotheses, and discussing and presenting information for future researchers and designers.
