HabiTree: Using the Growth of Nature to Develop New Habits and Rituals

Personal informatics systems commonly support habit formation through digital or paper-based trackers. However, these 2D interfaces often insufficiently engage the emotional engagement needed to support long-term behavior development. HabiTree addresses this by turning habit tracking into a tangible experience with meaningful presence. HabiTree is a physical, artificially growing tree whose LED-lit leaves visualize habit progress. Users log habits by touching capacitive “smart leaves,” triggering light patterns evoking tree growth as habits progress. Two modalities support different reflection styles: leaf-based tracking for individual habits and branch-based tracking for grouped behavioral domains. A companion mobile app enables remote logging, analytics, and feedback while preserving the core ritual of tending to the tree. By merging tangible interaction with personal informatics, HabiTree offers an emotionally resonant alternative to traditional trackers, highlighting how artificial growth metaphors can deepen reflection, support rituals, and enrich ambient, nature-inspired tangbile interfaces for wellbeing and personal data.
