Haptic Feedback for Improved Interoceptive Awareness and Mental Well-being
8. september 2026 opdateret af: Massachusetts Institute of Technology
Haptic Feedback for Improved Interoceptive Awareness and Mental Well-being: A Comprehensive In-the-Wild Study for Wellness
This study investigates the relationship between heart-beat haptic feedback on interoceptive awareness and mental-wellbeing.
Previous research showed non-significant results in short-term emotion regulation tasks when given heartbeat haptic feedback, suggesting the need for an extended adjustment training period to build trust with interoceptive feedback systems.
To address this, the experimenters propose an in-the-wild study where participants wear a Bangle.js
smartwatch for one week each under two conditions: (1) Real heartbeat feedback and (2) Off-set heartbeat feedback.
This design aims to examine the influence of haptic feedback on psychological characteristics, including alexithymia, anhedonia, depression, anxiety, and general mental health.
The experimenters will also explore the usability and comfort levels related to prolonged wearable use, as well as the participants' ability to distinguish between real and off-set heartbeat feedback, particularly across different levels of alexithymia traits.

Våben og indgreb
Deltagergruppe / Arm |
Intervention / Behandling |
|---|---|
|
Eksperimentel: Real heartrate feedback
Participants wear a smartwatch during all waking hours which delivers vibration pulses at a frequency matching the current heart rate sensed by the smartwatch
|
Participants wear a smartwatch during their waking hours which delivers pulses of vibration which can be matched to the frequency of the current heart rate (real condition) or heart rate from one hour ago (sham condition)
|
|
Sham-komparator: Sham heartrate feedback
Participants wear a smartwatch during all waking hours which delivers vibration pulses at a frequency matching the heart rate from one hour ago as measured by the smartwatch.
The time delay means that feedback does not match the current heartrate but maintains the overall descriptive statistics of the participant's heartbeat.

Tidsramme |
|---|---|---|
|
Center for Epidemiological Studies-Depression Scale
Tidsramme: Difference from measurement at the start of each arm to end of each arm (1 week span)
|
Measured by the standard scoring procedure in each lab visit at the start of the week.
Decrease is considered an improvement.
|
Difference from measurement at the start of each arm to end of each arm (1 week span)
|
|
Interoceptive accuracy
Tidsramme: 1 week (difference between SensHB at the start of each arm and the end of each arm)
|
Interoceptive accuracy measured using SensHb (slope of the correlation of estimated heart rate with smartwatch-recorded heart rate measured over three 1-minute measurement periods during the in-lab questionnaire)
|
1 week (difference between SensHB at the start of each arm and the end of each arm)
|
|
Snaith-Hamilton Pleasure Scale
Tidsramme: Difference from measurement at the start of each arm to end of each arm (1 week span)
|
Measured at the lab visit at the start of each week.
We sum the pleasure rating for each item so the score represents overall hedonic capacity (opposite of anhedonia).
Increase is considered improvement

General Anxiety Disorder-7 Anxiety Scale
Tidsramme: Difference from measurement at the start of each arm to end of each arm (1 week span)

Measured by the standard scoring procedure in each lab visit at the start of the week.
Decrease is considered an improvement.

Decrease is considered an improvement.

General Health Questionnaire-12 General Mental Distress scale
Tidsramme: Difference from measurement at the start of each arm to end of each arm (1 week span)
