A startup that created a dedicated gadget to help ensure the safety of electrical industry workers has turned their talents to addressing the need for similar workplace protections in the face of another threat: COVID-19. Vancouver-based Proxxi is launching Halo, a wrist-worn wearable device that can provide a vibration notification to alert someone of the presence of another band within 6 feet – the recommended span of separation to ensure proper social distancing.

Proxxi explains that the device is designed to help ensure compliance with social stance guidelines while on a job site or at a workplace, where essential work might need to continue despite the ongoing global coronavirus pandemic, but where it can also be tricky to maintain proper distance between workers without a reminder system.
