Summary
Neupane et al., "Momentary Stressor Logging and Reflective Visualizations", CHI '24 (DOI 10.1145/3613904.3642662; arXiv 2401.16307). Participants wore a Fossil Sport WearOS watch for 100 days; the watch triggered stress prompts when physiology suggested stress, and participants logged stressors and rated stress. IRB approved.
