VisceroHaptics: Investigating the Effects of Gut-based Audio-Haptic Feedback on Gastric Feelings and Gastric Interoceptive Behavior
Researchers' audio-haptic stomach device increased water consumption by 20% and manipulated hunger feelings in 55 participants.
A research team from ETH Zurich and Singapore University of Technology and Design has developed VisceroHaptics, a novel system that uses audio-haptic feedback based on gut sounds to directly influence stomach-related feelings and behaviors. The device applies specific vibration patterns to the abdomen, driven by synthesized or recorded digestive sounds. In their study, accepted for CHI 2026 with an Honourable Mention Award, the team conducted three controlled experiments with 55 total participants to rigorously test the system's effects.
Results demonstrated that different audio-haptic patterns could reliably induce targeted sensations: participants reported increased feelings of hunger, fullness, thirst, and even stomach upset. Crucially, the technology didn't just alter subjective reports—it changed behavior. When subjected to the Water Load Test-II, a standard measure of gastric interoception, participants who received the stimulation ingested significantly larger volumes of water compared to control conditions. This marks a pivotal shift from merely monitoring bodily signals to actively and noninvasively modulating them.
The work challenges the traditional boundary between external technology and internal bodily perception, suggesting our gut feelings are more malleable than previously thought. By providing the first concrete evidence that gastric interoceptive behavior can be altered through noninvasive means, the research lays a foundation for future therapeutic and interactive applications. Potential uses could range from supporting eating disorder therapies and managing satiety cues to creating more immersive, embodied experiences in virtual reality or wellness technology.
- The VisceroHaptics system uses stomach-applied audio-haptic vibrations based on gut sounds to influence internal sensations.
- In experiments with 55 people, it successfully induced hunger, fullness, and thirst, and increased actual water intake during tests.
- This is the first evidence that noninvasive stimulation can directly alter gastric interoceptive behavior, a breakthrough for human-computer interaction.
Why It Matters
This paves the way for noninvasive devices that could help manage eating behaviors, treat disorders, or create deeper immersive tech experiences.
