Abstract

This study addresses issues such as low treatment adherence and strong psychological resistance during the rehabilitation process for children with asthma. It proposes a service design framework based on gamification thinking that integrates hardware devices and software systems. The framework aims to enhance children's participation in rehabilitation through entertaining interactive experiences. Using the service design double diamond model combined with literature analysis, user journey maps, and NPS assessment methods, the study identifies core pain points in traditional rehabilitation products, such as a lack of interactive feedback, single training modes, and insufficient intelligence. The design incorporates a gourd flute-shaped hardware device that integrates breathing detection and nebulization treatment functions. Dynamic sensors convert breathing mechanics parameters into game commands, enabling children to complete lung function training through blowing-style interaction. The accompanying software system establishes a gamified reward mechanism combined with respiratory data visualization, forming a "detection-trainingfeedback" closed-loop system. User evaluations indicate significant recognition of the solution's functionality and product design, validating the effectiveness of gamified design in alleviating medical anxiety and strengthening treatment motivation. This study provides an innovative, cross-disciplinary paradigm for designing rehabilitation services for children with chronic diseases. Future research should optimize ergonomic details further and deepen the dynamic adaptation mechanism between medical data and game content.
