Lopos has developed SafeDistance, a small, light, wearable device
It measures the distance to the next nearest device in real time and warns you if it’s closer than 1.5 metres
You can set the minimum distance you want to respect
If someone comes too close, so within a radius of 1.5 or 2 metres, a beep sounds , the wearable vibrates and optionally an LED light comes on to warn you that more distance is needed.
