  One of the most important issues in requirements engineering (RE) is the
alignment of stakeholders' mental models. Making sure that all stakeholders
share the same vision of a changing system is crucial to the success of any
project. Misaligned mental models of stakeholders can lead to conflicting
requirements. A promising approach to this problem is the use of video showing
a system vision, so-called vision videos, which help stakeholders to disclose,
discuss, and align their mental models of the future system. However, videos
have the drawback of allowing viewers to adopt a passive role, as has been
shown in research on e-learning. In this role, viewers tend to be inactive,
unfocused and bored while watching a video. In this paper, we learn and adopt
findings from scientific literature in the field of e-learning on how to
mitigate this passive role while watching vision videos in requirements
engineering. In this way, we developed concepts that incorporate interactive
elements into vision videos to help viewers stay focused. These elements
include questions that are asked during the video and ways for viewers to
decide what happens next in the video. In a preliminary evaluation with twelve
participants, we found statistically significant differences when comparing the
interactive vision videos with their traditional form. Using an interactive
vision videos, viewers are noticeably more engaged and gather more information
on the shown system.
