A wearable device designed to help people who stutter, turning scientific research on vibrotactile therapy into a discreet, personal and easy-to-use everyday product.
- Research
- About 1% of adults worldwide stutter. Assistive solutions rely only on auditory feedback and are often ineffective and stigmatizing, while recent studies confirm the effectiveness of vibrotactile stimulation.
- Technology
- Rhythmic vibrations between 60 and 80 bpm act as a subtle “internal metronome” that supports the body’s natural sense of speech control.
- Prototype
- A hands-on, exploratory process focused on the physical sensation of the device. A working prototype was tested with a person directly affected by stuttering.
- Ecosystem
- Three accessories, designed from persona analysis, work in any wearing position. An app supports autonomous management, health monitoring and repair guidance.
