IntimaSea: Exploring Shared Stress Display in Close Relationships

Automatic stress tracking has become increasingly available on wearable devices. Research has investigated its use for individual stress management, largely within the traditional data-as-care framing. However, its use for stress sharing in social relationships, particularly close relationships, is still under explored. Inspired by the idea of “caring-through-data”, which focuses on mediating the social and emotional experiences of the collective “us” with data, this paper presents a design study with a prototype called IntimaSea, a display featuring illustrative stress data in collective forms to be shared among close relationships. The field trials with nine groups of intimately-connected users (N=19) highlight its potential on stress awareness, interpretation and management, as well as intimacy promotion. We end by discussing sharing stress for social ways of stress management, stress data as a meaningful social cue mediating relationships, as well as design implications for caring-through-data.
