The number of people in need of care increases constantly, and in the coming few years many seniors will depend on their close relatives for their care needs. These relatives very often need support to fulfill their role as informal caregivers. The YouDo prototype presented in this paper aims to provide special training programs for informal caregivers in order to help them to improve the quality of their nursing. This work illustrates first development concepts, used methods and techniques towards a modular, extensible and user adaptable multimodal information and training platform.
