Following initial responses, probing questions were asked, such as: “What aspects do you like about this product?” and “How do you envision yourself using this product daily?” The prototypes were discussed in random order. At the end of the session, the first author asked the participant to name the prototype or combination of prototypes they liked or did not like the most and why. The experience prototypes were successful in provoking reactions, thoughts, and feelings about the product concepts and potential scenarios of use. Through the monitoring aspects of the concepts, we learned that participants were positive about the possibility of tracking symptoms over time, as they expected symptom tracking to give them a better understanding of their respiratory health. Through the sensorpatch included in the wake-up experience, we learned that tracking should occur almost automatically, as the participants wanted the monitoring process to be as effortless as possible. “It is just like sticking a bandage on your wound. You feel nothing, and after a while, you just remove it”. (Male) Through the augmented reality experience (projecting life-like lungs on the body using augmented reality technology on a T-shirt), we learned that the participants were particularly enthusiastic about novel and innovative technologies, as they improved the perception of the product’s usefulness. The augmented reality visualization of the respiratory tract provided a realistic presentation of the lungs as “their own.” It allowed them to explore the respiratory system entirely by zooming into its various aspects, such as airways and alveoli. As one of the participants expressed: “Sometimes, I think the medication is not that important. (…) Only when you really experience complaints you look for your medication. However, when you use something like this (augmented reality T-shirt), and you see it is not going well over there, you directly are going to use it. Yes, I have the feeling that now I want to use my maintenance medication”. (Male, 44) Based on the gathered insights regarding the target group’s attitudes toward the prototypes, three design requirements were formulated: 1) the design should be able to objectively monitor the user’s respiratory health semi-automatically over time. 2) the design should engage the user in this monitoring process by providing a feeling that the product is innovative and useful. 3) the design should create awareness about respiratory health through feedback that is realistic and displays the respiratory system in its entirety. Second Iteration—the final concept Following the formulated design requirements, we conducted a second iteration consisting of another ideate, prototype, and test stage to arrive at a final concept. This process consisted of concept detailing and technical design, with descriptions extending beyond this paper’s scope. The final concept aims to provide awareness
