Airbuddy 2 review5/30/2023 Then, the system determines the current IAQ level based on the level of the air pollutant that has the lowest Air Quality Index (AQI) rating among the five air pollutants. This sensor transmits the measurements of these air pollutants to the server every 15 seconds. As the last stage of this project, this paper reports on the outcomes of a 2-month field deployment where we evaluated the usability of AirBuddy in real-world settings.įor IAQ sensing, we used an off-the-shelf sensor that continuously measures the levels of 5 air pollutants: fine particulate matter (PM 2.5), carbon monoxide (CO), carbon dioxide (CO 2), total volatile organic compounds (TVOC), and nitrogen dioxide (NO 2) (see Figure 1). Based on the findings from these previous studies, we developed AirBuddy, a mobile app that visualizes air quality indoors and outdoors in a child-friendly manner. Previously, we investigated children’s perspectives and design requirements through a review of existing applications and 2 sets of semistructured interviews with 12 children with asthma. Specifically, we aimed to adopt an iterative, user-centered design approach by involving potential users throughout the design process to employ their perspectives in design. Thus, this project aimed to create a mobile app for children with asthma to engage in monitoring and improving IAQ. However, few apps are available for IAQ monitoring, and even fewer apps are designed for children’s use. Mobile apps are increasingly available and used to facilitate various aspects of asthma management. A tool that allows children to monitor IAQ easily might help mitigate these problems by enabling them to reduce their exposure to air pollutants and make healthy choices themselves. Furthermore, childhood asthma management is complex because pediatric patients with asthma rely on caregivers to manage asthma, and caregivers cannot fully keep track of the environmental triggers to which a child might be exposed. However, it is challenging to detect air pollutants with human perception because many air pollutants are invisible and thus impossible to detect with human senses. Thus, it is crucial to keep IAQ clean and healthy for asthma management. Since children spend most of their time indoors, the condition of the indoor air quality (IAQ) determines their exposures to many air pollutants. Among the various triggers that contribute to excessive asthma morbidity, exposure to air pollutants is a significant environmental trigger that worsens symptoms and causes asthma attacks. One important aspect of asthma management is avoiding or reducing environmental asthma triggers. Īsthma cannot be cured currently, but good management can control the disease and enable people with asthma to sustain a normal, active life. Childhood asthma is especially concerning because it creates a substantial burden on the affected children and their families by requiring regular medical encounters, restricting the child's physical activities, and increasing the chance of school absences. Its common symptoms include coughing, wheezing, chest tightness or pain, and difficulty breathing. Asthma is recognized as the most common chronic disease in children, affecting approximately 12% of children worldwide.
