Interface design technique considering visual cohesion-rate by object unit

With the application development environment rapidly changing, the design of an interface that supports the complex interactions between humans and computers is required. In addition, profound knowledge of various fields is required to cover the requirements of different customers. Therefore, in this paper, we suggest an interface design technique that considers the cohesion-rate in each objects of user interface. To accomplish this, specific and detailed models to embody the user interface are presented on the basis of the following classification: 1) event object model, 2) task object model, 3) transaction object model, 4) form object model. If this detailed modeling work is performed, the visual cohesion of the prototype user interface can be improved and, on this basis, even unskilled designers can construct an improved user interface. Moreover, the proposed method promotes the understanding of the business process and reduces the frequency of system development.
