Chapter 3 58 3.3.3 Stages 3 and 4 – Ideation and prototyping The ideation and prototyping stages were directed at developing ideas and concepts that could be used to reach the design objective that resulted from the first 2 phases. To achieve this, the first author executed a brainstorming session with industrial design students to explore engagement strategies for the monitoring process (e.g., monitor asthma symptoms and monitor inhaler use) and how the data can be presented to patients with LHL to promote awareness. Four overarching design concepts resulted from these sessions, each combining multiple solution possibilities. The concepts included are (1) a smart wheeze-detecting sensor to objectively monitor asthma state, (2) an immersive experience using augmented reality to engage the user in the monitoring process, (3) a playful spirometer, and (4) a wake-up experience, displaying the result of nocturnal asthma symptoms. We translated the concepts into low-fidelity prototypes to explore their feasibility and facilitate the upcoming feedback session with the participants. The prototypes consisted of cardboard mock-ups, physical artifacts, and off-the-shelf products, such as an augmented reality t-shirt with a projection of the lungs (Figure 3.3). Figure 3.3 Low-fidelity prototypes and visual explainers positioned in an exhibition-style setup during the evaluation. 3.3.4 Stage 5 – Test Three patients with asthma and with LHL participated in the experience prototype evaluation sessions. The evaluations took place at the health facility in their neighborhood,
