MoPeDT - Features and Evaluation of a User-Centred Prototyping Tool

User-Centred Prototyping (UCP) tools are expected to support interface developers in order to more efficiently, effectively and satisfactorily design, evaluate and analyse user-friendly products by an all-in-one tool solution. We developed such a UCP tool called MoPeDT that supports the user-centred development of interactive evolutionary prototypes for mobile phones in the context of the Internet of Things. In this paper we address our tool features for the design, evaluation and analysis phase that mostly base on meaningful features from related tools. Additionally, we cover potential enhancements to former UCP tools in order to support interface developers with a wide-ranging playground to investigate the user's behaviour and preferences. The paper also describes MoPeDT's evaluation with 20 students over one month that investigated the interface developer's efficiency, effectiveness and satisfaction when applying our UCP tool. As an outcome of this study we describe potential benefits and problems that might be of interest to other developers of UCP tools.
