In order to motivate diverse user groups to participate in e-participation, platform designers are keen to offer attractive communication formats in combination with modern tools and suitable forms of online identification. This does not come without difficulties, as individual users prefer different solutions. Research on tools and electronic identification in this context has investigated the appropriateness of different e-IDs for different stages of e-participation. In this respect, this paper offers three contributions to questions of technology application and acceptance in e-participation: Firstly, it showcases two scenarios from a platform simulation on different levels of e-participation. Secondly, the authors present results on the acceptance of these scenarios and tools based on questionnaires and usability tests. Thirdly, viewpoints from interviews with key stakeholders for e-participation in governance and politics are included. Results shall be useful for the future design and implementation of e-participation platforms.
