Developing UX for Collaborative Mobile Prototyping.

Prototyping is an essential part of the user-centered design process (UCD). Since the emergence of touch-based mobile devices in recent years, a broad range of efforts has been taken to adapt professional prototyping tools to the mobile context. However, none of the existing mobile prototyping solutions adapts sufficiently to the needs of multidisciplinary teams or considers the experience of the users’ working environments explicitly. Our goal was to develop a mobile prototyping tool that supports the users in their tasks with special attention to the context of use. We especially considered the holistic experience relating all tasks of the human-centered design process. Our approach of requirements engineering focused on UX methods to get a deep insight not only on pragmatic features but also emotional demands (i.e. hedonic qualities). Therefore we tried to strengthen the hedonic qualities to support action mode usage for leveraging creative potentials. We’d like to reveal whether and to what extent a detailed look on UX can ensure the working progress efficiency and motivation of a multidisciplinary software engineering team practicing agile methods. We will illustrate this by presenting the development process of our mobile prototyping tool Prime, especially concerning new perspectives of a design process that focuses on hedonic parameters.
