This document presents the D3.1 - GreenSCENT platform design and integration by introducing the theoreticalframework of the Sustainable Interaction Design, its historical roots, its current methods and researchperspectives and, in particular, the designing for low resource scenarios approach developed in theGreenSCENT project. This deliverable describes the interaction and interface design activity developed withinTask 3.1 - Design concept and interaction design of the GreenScent Identity, including the description of theiterative, participatory and incremental design methodology implemented in the task and all the design cycles,regarded as internal to the design team as well as with the involvement of end users. At the core of the deliverable there is the EXPLOR design concept that integrates the many perspectives ofGreenSCENT into an educational service and interaction design activity. EXPLOR suggests a unique journeythat integrates multiple users' perspectives, including the teachers, the students, the researchers, into asustainability education GreenSCENT scenario. The EXPLOR concept allows the reader to also put in relationthe different technologies of the GreenSCENT ecosystem, the way of interacting with these systems and thepossible adoption in sustainability education, meaning the GreenVERSE, the GreenSCENT mobile app, theGreenSCENT AR Mobile App and the GreenSCENT CleanAir App.
