Shutterstock Could artificial intelligence help restaurants reopen in a safer way? Seattle-based RealNetworks hopes so. The 26-year-old tech company has recently launched an app called MaskCheck that can detect whether someone is wearing a face covering properly through AI and encourages compliance via audible feedback. Though the app is generally intended for use in heavily trafficked venues, such as schools and public transportation, restaurants may find it useful as well, particularly once restrictions on indoor dining lift again. The free app — available nationwide for Android and iOS — uses a tablet’s camera to determine full coverage for masks over a person’s nose and mouth, without using facial recognition or collecting any personally identifiable information. It then produces an audio message depending on whether someone is “good to go” or needs to make adjustments to the mask. The app can also send alerts to a manager of the venue if someone is detected without a face covering on at all.
