 Welcome to Spotlight Advanced. I'm Bruce Gulland. And I'm Liz Wade. Spotlight uses a special English method of broadcasting. It is easier for people to understand no matter where in the world they live. Imagine these situations. A young man is walking in the hills, but he is lost. It is getting dark. The man cannot see anything. He falls and hurts his leg. Now he cannot walk and needs help immediately. But he does not know where he is. He cannot ask anyone to come and help him. He does not know how to tell anyone where to find him. A young woman is at an outdoor music event. During the event, she is planning to stay in a tent with her friends. She knows which field they are in, so she walks around the field looking for them. But she cannot find their tent. She does not know how to find the exact position of her friends. Have you ever been in a situation like this? We do not always know where we are, even with modern technology. This can be annoying in some situations, but it can be very dangerous in other situations. Chris Sheldrick has created something that helps people when they face a problem like this. It helps people all over the world who cannot give an address or say where they are. It is called What Three Words. Today's spotlight is on Chris Sheldrick and his app What Three Words. Chris Sheldrick lives in the United Kingdom. He worked in the music industry for ten years. He organized music events around the world. But every day he had problems with addresses. Musicians and people bringing their equipment often got lost when they tried to find an event. One day in Italy, a driver unloaded equipment at a place one hour north of Rome. But he should have unloaded it one hour south of Rome. Sheldrick tried to get the people he worked with to use longitude and latitude to find where to meet. Marking places like this is exact. But it creates a line of sixteen numbers to mark the place. It is too difficult to use. Sheldrick wondered if he could change these numbers into something easier. Sheldrick had a friend who worked with mathematics. The two men worked together on this problem for six months. They found a simple way to talk about where a person was, their location. In a TED Talk, Sheldrick explained what they did. We divided the world into three metre squares. We found that we could name every three metre square in the world separately with just three words. We used forty thousand words which is more than enough for the trillions of squares. So the men gave every square or place a separate three word address. For example, their company building in London has the address filled, count, soap. And the door of the UK Prime Minister is slurs this shark. Sheldrick called this new system What Three Words. He built an app people can use to find places this way. He knew that it could do much more than get musicians to the right place. He believed that What Three Words would help billions of people in the world who still live without an address. He told the Guardian If you think about addresses some are from centuries ago. Some are from last week. But there is so much of the world that does not use them. Complete countries like Mongolia or Saudi Arabia have only ever used directions. Sheldrick knew that people without an address sometimes struggled to get the same services as people who do have an address. For example, if you do not have an address you will find it hard to get a bank account, be listed to vote or receive a letter. So his company built What Three Words into many languages from Arabic to Urdu. This means What Three Words can help people in countries that do not have a good address system. It can help people in life or death situations. It can even help businesses work better. In his TED Talk Sheldrick explained some of the ways that What Three Words has already been used. In Durban, South Africa an organisation called Gateway Health provided 11,000 Three Word address signs in their community. Pregnant mothers can call the emergency services and use the signs to explain exactly where to find them. In the past, the ambulances have often taken hours to find the pregnant mothers. In Mongolia, the National Post Service uses the system. They are now taking mail to many people for the first time. The United Nations are using it to mark photos or pictures in disaster or trouble areas. They can then take aid to exactly the right place. Even Domino's Pizza use it in the Caribbean. They want to get their food to people while it is still hot. People all over the world use the What Three Words app. It is free to emergency services and individuals. In the United Kingdom, Jess Tinsley and her friends went for a walk. But they got lost. It was dark and wet and Tinsley was near to tears. She said, We were in a field and had no idea where we were. She got a phone signal and called the emergency services. They told her to use the What Three Words app. She quickly did this. The emergency services knew where she was in less than a minute. Soon they found and rescued Tinsley and her friends. In Uganda, What Three Words worked with the Community Development Centre to bring three-word addresses to refugee camps in the area of Arowa. The centre will discover and record three-word addresses for every home and important building in the camp. This means health workers will be able to find people who need medical services. But it means much more than this. Sebit Martin is a leader at the Community Development Centre. On the What Three Words website, Martin explained why it was important for refugees to have an address. We want to give refugees the self-respect they deserve. We can improve their living conditions. Three-word addresses will give everyone an easy way of talking about places. But these addresses are also a better language of hope in the refugee camp. Do you have an address? Have you ever had problems finding a place? Would this app help you? Tell us about it.
