Amazon has created a new AI called the Distance Assistant to help its fulfillment facility employees keep a safe distance from one another during the ongoing coronavirus pandemic. Using a time-of-flight sensor similar to the depth-sensing cameras you'll find on modern smartphones like the Galaxy S20, the assistant measures the distance between employees. The AI component is there to help it differentiate people from the background. What the AI sees is then displayed on a 50-inch screen for workers to glance at as they pass high-traffic areas.
The final piece the puzzle is an augmented reality overlay. In a kind of magic-mirror like way, employees will see a green or red circle around them on the display. As you might have guessed, green means they're at least six feet apart from one of their co-workers, while red means they're too close. The entire system runs on a local computer and doesn't need assistance from the cloud.
