Abstract:This Creative Technology thesis explores the use of haptic feedback to teach breathing techniques, offering a tactile and personal learning experience. The study aimed to identify key characteristics of haptic stimulation patterns for guiding breathing exercises. A prototype, the Wearable Haptic Breathing Assistant (WHBA), was developed with an ESP32 microcontroller, a breathing sensor, and eight vibrotactile motors arranged around the abdomen. User testing involved two rounds with six participants each, using questionnaires and interviews to evaluate six aspects of haptic patterns contributing to overall comfort. Four initial patterns were tested, using the feedback to improve the prototype with which five other haptic patterns were tested in a second user test. Patterns included time cues without feedback, guiding feedback, direct feedback, and terminal feedback. Results indicated a preference for guided feedback and reassurance, with clear guidance reducing cognitive load and enhancing relaxation. Active vibration patterns were found to be stressful. The study highlighted the importance of responsiveness, accuracy, and consistency in tracking breathing, and the need for durable, high-fidelity motors. The research addressed six key questions through literature review, analysis of existing research and products, and user tests. Recommendations for future research include enhancing haptic breathing systems' responsiveness and comfort.
