The KosmoS project, funded by the German Federal Ministry of Education and Research under grant number 16SV8414, ran from 1 February 2020 to 30 June 2022 and was led by Dr. Serge Autexier of the German Research Center for Artificial Intelligence (DFKI). It was a consortium effort that brought together DFKI’s Cyber‑Physical Systems and Interactive Textiles research groups, the partner project DAI, and several IvGA projects such as UbiAct, ConText, Schreibtrainer, and CoPoT. The main objective was to develop a modular, mobile Smart Life Lab kit—CoMobiLL—that combines versatile room‑forming elements, a software platform, and a set of methods and activities for living‑lab research.

Technically, the project produced a fully integrated living‑lab environment that could be deployed in both stationary and mobile settings. The modular kit includes configurable textile surfaces that provide electrical power, data communication, and intuitive gesture‑based interaction with IoT devices. The software stack features an open‑API documentation system (RapiDoc) and an AsyncAPI interface, enabling seamless integration of heterogeneous demonstrators. A rule‑engine editor was also developed to allow non‑technical users to define interaction logic. The demonstrators from partner projects were connected to the living‑lab infrastructure and evaluated in real‑world scenarios. For example, the CoPoT demonstrator was assessed for ergonomics, usability, and emotional resonance during a user‑research session in the Berlin Open Lab (BOL). The ConText demonstrator was integrated into the BAALL Maker‑Lab and mobile modules, and its user experience was measured through a series of usability tests. In the summer of 2022 and 2023, the UbiAct, ConText, and Schreibtrainer demonstrators were showcased during the Long Night of Science, attracting roughly 500 visitors in 2023. One interactive exhibit allowed participants to control a lamp by writing a color on paper, demonstrating the system’s ability to translate simple user inputs into device actions.

The project also focused on participatory design and knowledge transfer. Three cross‑project workshops addressed human‑technology interaction, ELSI aspects with a focus on security and privacy, and methods for involving users in living‑lab studies. Remote workshops were conducted using online templates and whiteboard tools to define living‑lab scenarios and CoMobiLL configurations. The final networking event at the Berlin Open Lab featured presentations of partner results and workshops that employed CoMobiLL elements. Although the COVID‑19 pandemic delayed some demonstrations, the project succeeded in making the demonstrators accessible to end users through a variety of events, including Girls’ Days, the BAALL Maker‑Lab, and the Autumn Academy.

Collaboration was structured around a living‑lab management framework that coordinated technical and organizational aspects across projects. The DFKI team handled the design, implementation, and evaluation of the modular kit, while partner projects supplied demonstrators and user scenarios. The consortium held regular coordination meetings to align requirements, share best practices, and plan joint outreach activities. The project’s outcomes are documented in a final report that includes detailed performance data, user‑feedback metrics, and a roadmap for future deployments. The modular living‑lab kit and its associated software platform are now available for use by researchers and developers interested in rapid prototyping of smart‑home and IoT applications.
