What if you could see invisible health data in your immediate area? Candy worked with Spatial Information Design Lab director Sarah Williams and Columbia University Computer Science PhD candidate Sean White on visualizing air quality data for mobile devices. After recording and geocoding carbon monoxide levels around Manhattanville in New York City, the group explored ways this information could be made accessible on mobile devices and augmented reality views. Candy helped design ways users can explore air quality data in their immediate surroundings through map views, live street views, and other layers of information such as land use, demographics, data points, and interactive messages. In the end, this work will help improve site visit tools for architects and urban planners and make invisible health data more accessible to people through mobile devices. 2008.
