Smartphone app helps blind people stand in socially distanced lines

During the pandemic, everyone is expected to stay socially distanced, with at least six feet between them and the person in front of them. For those with normal vision, standing in line while remaining at a safe distance from the person in front of you isn't a problem. However, for the blind or visually impaired, maintaining an appropriate distance can be a challenge. A team of IBM researchers have created an AI-driven smartphone application called LineChaser to solve this problem.
