However, as recent studies suggest, the effects of such tracking devices are debatable 2, seem to be short-lived, and consumers often stop using them after a short period of time 3. Across most such instantiations of wearable technologies, the overarching aim seems to be the quantification of the self 1. Wearable devices are becoming ubiquitous in everyday life, serving a range of functions, from measuring physical activity and a range of physiological variables to providing feedback on emotional states. This finding is discussed in relation to past research on responses and entrainment to rhythms, and their effects on arousal and mood. Therefore, the presence, as opposed to its absence, of a slow rhythm, which in the present study was instantiated as an auxiliary slow heartbeat delivered through doppel, had a significant calming effect on physiological arousal and subjective experience during a socially stressful situation.
Calming heartbeat sound skin#
Participants in the doppel active condition displayed lower increases in skin conductance responses relative to baseline and reported lower anxiety levels compared to the control group. For only one group, the device was turned on and delivered a slow heartbeat-like vibration. Both groups wore the device on their wrist during the anticipation of public speech, and were given the cover story that the device was measuring blood pressure.
Two groups of participants were tested in a single-blind design. We tested whether the use of doppel would have a calming effect on physiological arousal and subjective reports of state anxiety during the anticipation of public speech, a validated experimental task that is known to induce anxiety.
We assessed the calming effect of doppel, a wearable device that delivers heartbeat-like tactile stimulation on the wrist.
