Scenarios are commonly used to develop new systems in multidisciplinary projects. However, written scenarios are sequential, not dynamic and often too abstract or difficult to understand for end users. The goal of this paper hence is to extend the use of scenarios in design methodologies, using an interactive scenario visualization (ISV) approach. After discussing scenario-based design, we show that ISV can be used beneficially to develop a new ICT system and that ISV aids in reflection upon the design trajectory. Comparing two software platforms, we found it was possible to develop such ISVs inexpensively, rapidly and with good visual quality. As a case study, we demonstrate the use of a home care telemedicine system in 3D for discussion and development purposes. An evaluation among n=22 professionals illustrates that ISVs can prove useful in design, aid in clarification of new systems, are suitable to demonstrate system functionalities, and aid in articulating feedback. Finally, we discuss generalization of the use of ISVs.
