Helping kids cope with the fear of medical treatment

According to Gabriella Mullingan a technology of bussiness reporter,BBC ,For children, the fear and pain of medical treatments can be traumatic. So a number of tech companies have come up with ways to help.
Vaccinations save lives, but many children fear the needle.
So one project in Brazil has turned to virtual reality (VR) as a way of helping kids cope.
The VR Vaccine project involves them wearing a VR headset and watching a 3D animated adventure story involving heroes in coats of armour defending their land against a villain.
The nurse can see the story on a separate screen and the action is synchronised with action of cleansing the skin and applying the injection.
The project was launched by pharmacy chain Hermes Pardini to help with their vaccination campaigns, with local design studios VZLAB and Lobo creating the content.
