A redesign of a visual programming language inspected with cognitive dimensions of notations

Abstract [en]

This report describes a redesign of a process modeling program, reMind. The new design, called reMind+, is presented and evaluated from a usability perspective. reMind lets the user model an industrial process by using a graphical user interface. The model is defined by a node-link diagram, and it is possible to add functions to the nodes. This model is then transferred to a tool that optimizes the process. Remind uses a graphical editor to construct a node-link based model of a process. reMind has however usability problems. For example, only a limited set of functions are available for process components. The design of reMind+ blends user requirements together with research results in the area of Human-Computer Interaction to overcome reMind's limitations. The most important user requirements are possibility to add user defined functions, support for reuse of models that been built, and an improved model editor. An evaluation of reMind+ is performed with a system called Cognitive Dimensions of Notations (CD). CD focuses on usability and the design trade-off. This report concludes that the cost for the added functionality is an increased learning threshold for the application.
