Together with the project partners of Gecko Two GmbH and CG Elementum AG, the 2nd and 3rd workshop of the OPTIMISE project took place on December 07, 2021 and January 19, 2022 at the premises of Gecko Two GmbH and InfAI, respectively. The core objective of these meetings was the detailed elaboration of use cases in the Smart Living domain to be implemented within the OPTIMISE project. The organization and methodical design of both workshops was carried out by Gecko Two GmbH. During the 2nd workshop a questionnaire was developed to serve as a basis for the identification of preferences, wishes, but also concerns of current and potential users of Smart Living solutions. As a result of the 3rd workshop, different maturity levels of Smart Living services could be identified and first use cases to be implemented within the project could be derived from them. In addition, the possibilities for practical implementation of the use cases were discussed and initial technological and organizational measures were recorded that will be undertaken by the project partners in this context.
