ABOUT

HEALTH GREETER KIOSKS

A pilot project from UNC Reese Innovation Lab

THE GOAL

Check mark on a face mask icon.

This project is designed to encourage our community to wear masks and practice proper spacing guidelines when moving through buildings. By using human-centered design and emerging technology, the Reese Innovation Lab has developed a pilot project to promote the University's Guidelines for Fall 2020.

HOW DOES IT WORK?

Using artificial intellligence (AI), specifically computer vision and machine learning, these kiosks detect if a person is wearing a mask or remaining properly spaced when entering a building. The computer vision team has tested the kiosks with a variety of skin tones, masks colors and patterns, and accessories.

ARE THESE KIOSKS RECORDING DEVICES?

A video camera icon.

No. Thirty times per second, a single frame of video is analyzed to count and highlight a face and determine if they are weraing a mask or not. The frame and graphics are displayed on the screen in real-time, then immediately deleted as the next frame is analyzed and presented.

No audio or video is recorded or transmitted. School administration or law enforcement agencies will not access the video from the Kiosks. This system does not use facial recognition technology or any process to identify individuals or groups.

WHERE WILL THEY BE?

A location pin icon.

The kiosks will be piloted in the following areas:

  • Carroll Hall (Hussman School of Journalism and Media)
  • McColl Building (Kenan-Flagler Business School)
  • Gillings School of Public Health
  • School of Information and Library Sciences
  • And other areas over time

WHAT ABOUT THE DATA?

The system counts the number of masks worn and the distance between people. It is encrypted and stored as aggregate data and then transmitted from each kiosk every 5 minutes via HTTPS protocol. We are following all university data security protocols.

CAN I OPT-OUT OF THIS PROJECT?

An open door icon.

Absolutely. This is an opt-in/opt-out experience, so other entrances will be marked to the buildings. These entrances are also accessible for those who need wheelchair access.
