The government is exploring the use of artificial intelligence technology to detect what proportion of people using public transport are wearing a face covering. In addition to monitoring the use of masks, the tech system could also be used to display messages designed to encourage their use. According to rail minister Chris Heaton-Harris, work to trial the use of such technology is currently at the stage of being a “proof-of-concept study”. We are investigating a non-intrusive AI-model capable of detecting the number of face-coverings, and the number of uncovered faces, in an image, he said. The model would then display message responses focused on positive engagement. This work will not be able to identify or track individuals, and no images will be stored by the system. Heaton-Harris added that this project – and others exploring the use of emerging technology – are supported by specialist teams at the Department for Transport.

Facebook says it has deployed a feature in its Community Help hub to make it easier for users to assist each other during the pandemic. As of this week, AI will detect when a public post on News Feed is about needing or offering help and will surface a suggestion to share it on Community Help. Once a post is moved or published directly to the hub, an algorithm will recommend matches between people. For example, if someone posts an offer to deliver groceries, they'll see recommendations within Community Help to connect with people who recently posted about needing this type of assistance. Similarly, if someone requests masks, AI will surface suggested neighbors who recently posted an offer to make face coverings.
