Smart devices are a part of everyday life and screen use is quickly becoming a ubiquitous activity. Related studies have shown that families are experiencing tensions in relation to in-home screen use and that they often fail in trying to implement strategies to address these tensions. This study explore to what extent the Self-Determination Theory and gamification can be utilized to help families reflect on tensions regarding their screen use. We studied how the Self-Determination Theory can be used to map existing feelings towards the motivation to address screen use related tensions. Using Research through Design combined with digital ethnography we have investigated how implementing our board game design called "Free Time" can help sprout motivation towards establishing shared expectations to family time and thereby alleviate tensions related to screen use. In conclusion, this study is a contribution to the field of HCI research on the topic of technological tensions emanating from use of smart devices. Our main contribution with this study lies in the finding that Free Time can influence perceptions on tensions, but also actual behaviour, surrounding screen use during family time. This study suggests that the Free Time could improve upon family time by its ability to bypass the reluctance of family members to engage in screen use related discussion by fear of conflict, found in related work on the subject.
