Akıllı telefon çağında yüz yüze sosyal etkileşimlerin zenginleştirmesinin tasarım odaklı araştırılması

The quality of social interaction has great importance for psychological and physiological health. Previous research indicates that smartphones have adverse effects on collocated social interactions. Many HCI studies addressed this issue by restricting smartphone use during social interactions. Although the results of these studies indicated a decrease in smartphone use, restrictive and limiting approaches have limitations. Users should have high levels of self-regulation to comply with them, and they may lead to unintended outcomes like withdrawal symptoms. Considering the influence of smartphones on people's social relations and interactions, either positive or negative, there is a need for new solutions to mitigate the adverse effects of excessive smartphone use alternatives to restrictive approaches. To this end, this thesis aims to explore individuals' smartphone use behavior from the standpoint of social interactions and relations by employing diverse data collection techniques, i.e., how this behavior hinders and supports social interactions. We started investigating this question through in-situ observations and focus group sessions. With the information learned from this step, we developed two research prototypes to enrich social interactions without restricting smartphone use. We then collected users' thoughts, reactions towards, and concerns about these prototypes through user studies. Finally, we examined how these prototypes influenced conversation quality in social interactions through an experimental user study. Along with the motivation and aim, this thesis makes knowledge and artifact contributions to the growing field of digital well-being. We identified 21 user insights, nine design implications, and four design approaches that will guide the design of innovations and solutions to enrich social interactions in the presence of smartphones. We developed two design concepts, which also served as the validation of these knowledge contributions.
