The project Forgotten Colours analyses colour pigments of medieval wall paintings from diverse churches in the northeastern alpine region. One goal is to communicate the findings via an AR application. The main system requirement is to superimpose a digital layer displaying the original polychromy of selected scenes. This bachelor thesis aims to provide a value-oriented requirements analysis. The intention is to define and implement a project-tailored approach involving domain experts and AR designers in a fruitful dialogue during the early design process.

Based on the Value-Sensitive-Design concept, a project-specific action plan is defined and implemented. It includes multiple phases focusing on conceptual, technical and empirical aspects. The initial investigation steps prepare the ground for a value-oriented exchange with domain experts. The main output is a prototype that presents one possible way of transforming project values into an AR experience. It enables the interdisciplinary dialogue by providing the technical background: The included value propositions are iteratively discussed, adjusted and complemented.

The Value-Sensitive-Design approach provided a valuable toolbox to create a project-tailored and value-oriented action plan for the requirements elicitation process. The AR prototype has facilitated the interdisciplinary dialogue regarding domain-specific and technical knowledge. It figured as the primary enabler of the conversation between AR experts and domain experts, including context- and user-specific requirements and addressing some valuable project aspects: It communicates not only the original polychromy of the wall paintings but also visualises the scientific research approach, focusing on the single colour pigments and showing the sequences of the painting process. Additionally, the exchange with domain experts, including conceptual, technical and empirical methodologies, has allowed the creation of a value pyramid that demonstrates which project values are delivered on each research layer of the project work. The value pyramid and the initial prototype deliver a stable basis for further development of the planned AR application that will provide visitors with valuable new insights about the medieval wall paintings analysed in the Forgotten Colours project.
