Over the past decades, numerous concepts and prototypes for fostering emotional connections across distance (relatedness technologies) have been proposed. This has made it challenging for researchers and designers in Human-Computer Interaction (HCI) to maintain a comprehensive overview and effectively build on previous work. To address this, we conducted a systematic literature search (PRISMA) and collected 241 concepts and prototypes (2010-2024). We organized this corpus according to key aspects: (1) target population, (2) theoretical grounding, (3) design, (4) evaluation, and (5) ethics. Based on this, we developed the “COmpendium of RElatedness Technologies” (CORE), an open-access, searchable online database that provides researchers and practitioners with a reliable repository to inform future work. In addition, we present a systematic review of the corpus, revealing that despite its long tradition work on relatedness technologies remains characterized by limited theoretical grounding, lack of robust empirical evidence of effects, and insufficient attention to ethical considerations.

The rising issue of excessive screen time among children is a significant concern due to widespread access to digital devices. Several strategies for reducing screen time already exist, although their effectiveness varies. We investigated the transition from screen time to non-screen time activities. "Watch with Joy" is a child-friendly video-player which, based on the videos you watch, can suggest activities for the non-screen time. Our four-week qualitative study involving four families revealed that the incorporation of alternative technological methods can ease the transition to non-screen time. A character can facilitate communication with the child. Providing non-screen activities shifts the child’s focus away from turning off the screen and possible negative emotions. Consequently, the child has more time to adjust to accepting the end of screen time. In conclusion, our research underscores the significant role of parents and their parenting styles in shaping the success of such a technology-based approach.
