Video as a By-Product of Digital Prototyping: Capturing the Dynamic Aspect of Interaction
Requirements engineering provides several practices to analyze how a user
wants to interact with a future software. Mockups, prototypes, and scenarios
are suitable to understand usability issues and user requirements early.
Nevertheless, users are often dissatisfied with the usability of a resulting
software. Apparently, previously explored information was lost or no longer
accessible during the development phase. Scenarios are one effective practice
to describe behavior. However, they are commonly notated in natural language
which is often improper to capture and communicate interaction knowledge
comprehensible to developers and users. The dynamic aspect of interaction is
lost if only static descriptions are used. Digital prototyping enables the
creation of interactive prototypes by adding responsive controls to hand- or
digitally drawn mockups. We propose to capture the events of these controls to
obtain a representation of the interaction. From this data, we generate videos,
which demonstrate interaction sequences, as additional support for textual
scenarios. Variants of scenarios can be created by modifying the captured event
sequences and mockups. Any change is unproblematic since videos only need to be
regenerated. Thus, we achieve video as a by-product of digital prototyping.
This reduces the effort compared to video recording such as screencasts. A
first evaluation showed that such a generated video supports a faster
understanding of a textual scenario compared to static mockups.Comment: 7 pages, IEEE International Requirements Engineering Conference
