Array of Things Public Meeting at Harold Washington Library

On June 22, 2016 from 5:30pm - 7:00pm at Harold Washington Library in the Loop, residents came together for a public meeting about sensors, privacy, data & the Internet of Things in Chicago.


  1. The purpose of the Array of Things Public Meetings is to educate the public on the Array of Things project and help facilitate community feedback on the Array of Things Governance & Privacy policy.
  2. These are open meetings in Chicago Public Library Branches. No knowledge of technology or sensors is required to be a welcome, meaningful addition to the event.
  3. Smart Chicago kicked off the meeting, welcoming residents and introducing the two main speakers: Charlie Catlett of UrbanCCD & Brenna Berman, CIO for the City of Chicago.
  4. Charlie Catlett explained that The Array of Things is a network of interactive, modular sensor boxes that will be installed around Chicago to collect real-time data on the city’s environment, infrastructure, and activity for research and public use.
  5. Since these sensors will be collecting data in public spaces, a privacy policy was crafted that describes how personally identifiable data will be handled by the sensors & by researchers. Brenna Berman provided an overview of the governance & privacy policy.
  6. At the meeting, Chicago residents asked questions and provided comments about the governance & privacy. Those who could not attend can submit feedback online: 
  7. The OpenGov Foundation visited the public meeting, helping residents sign up for and use their Madison Platform. Madison lets users annotate on the text of draft bills or policies. Here is the Array of Things Privacy Policy on Madison:
