The Master thesis by Willem Span covers the student’s exploration of Jacob Jensen Design’s and Jacob Jensen Brand adoption of smart device applications. The thesis explores what opportunities applications may bring related to the companies’ aspirations. The project exemplifies those opportunities by the development of the social playlist app for the Tangent Fjord wireless speaker. The project has kept a focus on interpreting JJD’s design process and form language towards application design, complemented with influential factors originating from app design analysis.
