A Belgian city has come up with a solution to the problem of pedestrians bumping into other people while sending text messages from their mobile phones.
Antwerp has given smartphone users their own designated lanes, where they can walk while texting or looking at their mobiles without irritating or endangering others.
The narrow corridors are marked "text walking lane" in English on a number of busy pedestrian shopping streets in the city centre.
The markings on the ground are in white paint, but some lanes wind through narrow cobbled streets.
Negotiating the corners is likely to remain challenging for people whose eyes are glued to their phone screens.
