Designing the human interface is an important systems design activity. This week we will see the form and report design, interface and dialogue design, and dialogue diagramming. Form and report design is a key ingredient for successful systems because users often equate the quality of a system to the quality of its input and output methods. A key to designing usable forms and reports is consistency. Students can gain the skills needed to design consistent, usable forms and reports by learning the guidelines of formatting information, using color, highlighting, and avoiding the biasing of information.
What are the different types of errors, and what are some of the ways we can design our system to provide clear error messages and feedback to the user? What happens if the feedback is unclear?
