This research explores what types of devices humanity might build in order to breathe ambient air in hyper-polluted futures. One such device is the PERA - Personal Ecosystem Respirator Apparatus: a backpack-style wearable which contains the user’s personal-ecosystem to provide them with clean air through a respirator mask. Using the approach of speculative design, the intention is to highlight the consequences of our actions and inactions on climate change and show a world in which we have failed to address the issues of air pollution and global warming. Following a hybrid methodology created from a mixed methods approach, the research was conducted through an iterative process. Throughout the research, there was an increasing focus on the symbiotic relationship between the user and their ecosystem, and how one protects and provides for the other. The result of the work is a speculative wearable device which relies on James Auger’s theory of perceptual bridges in order to help build a believable and relatable future for the viewer.
