3 Participatory design for and with patients with low health literacy 59 were audio-recorded, and took approximately 1 hour. Participant responses (e.g., experiences, attitudes, thoughts, and needs) for each (part of the) prototype were captured with corresponding quotations. Two days before the session, the participants received a link to a short introduction video. In the video, the researcher introduced himself and explained in lay terms the research setup. This helped set a familiar face, manage expectations, and build initial rapport. This was deemed essential to facilitate the participants’ engagement, as anxiety toward research and the research team is a common barrier in socially disadvantaged groups (Bonevski et al., 2014). The session started with a brief individual interview about the demographics, living conditions, and how the participant experienced their asthma. Thereafter, the first author presented the prototypes and invited the participant to interact freely with them. Verbal and nonverbal responses were carefully observed and documented. 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 sensor-patch 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:
