BeUpright: Posture Correction Using Relational Norm Intervention
summary
BeUpright uses a shirt-mounted TI accelerometer with magnets, calibrates a personal upright, flags tilt >6° for 20s then vibrates and gives 10s to correct before locking a helper’s phone which the helper must shake phone 10 times to unlock; a two-week study with 6 control targets and 6 target-helper pairs logs ~3,000 poor-posture events and shows higher correction rates for the relational norm intervention, machine alerts habituate over days while the human-linked condition improves, and the strongest motivator is users’ desire to avoid causing helper discomfort.
