So-called relatedness technologies aim to create relatedness experiences between people over distance. Typically, such technologies focus on implicit or expressive interaction, as opposed to the explicit, information-focused interaction of conventional communication technologies. Based on psychological theory, previous research has identified different design strategies for relatedness technologies such as awareness, expressivity, or gift giving. However, despite this profound theoretical understanding, designing for a fulfilling relatedness experience remains a challenging task and often conflicts with other psychological needs, such as autonomy or security. This research explores the specific potentials and barriers to the use and acceptance of relatedness technologies. Based on a comparative evaluation of five different relatedness concepts in an online study (N = 221) combining quantitative and qualitative data, we identified overarching patterns of promising design strategies for particular user groups and revealed overall need fulfillment as a central predictor of the intention to use the technology.
