Bluetooth-sensed social presence is associated with immediate vigor and delayed fatigue: A multi-method time series analysis by David Willinger, Stefan Stieger

“…We examined these patterns through an experience sampling method study with 80 participants over two weeks (k = 3,716 assessments), combining Bluetooth device counts (n = 123,574) as a social presence proxy with self-reported emotional states. Using linear mixed-effects models, continuous-time structural equation models, and multi-state Markov analyses, we uncovered complex temporal relationships between social presence and emotions. …”
