Smart home
Technology will allow homes in the future to be “smart.” Appliances will communicate with each other - and with you. Your stove, for instance, will tell you when your food is cooked and ready to eat. Refrigerators will suggest recipes based on food items you already have. The technology is possible because of tiny information-storing devices called RFID chips. People already use them to keep track of pets and farm animals. Future RFID chips will store information about all the items in your cabinets. For example, they will record the date that you bought each item. Other devices will “read” this information using radio waves. When you need more food, your cabinets will tell you to buy it.
But how about your cooked breakfast, and the umbrella and hat you found by the door? For those, you can thank your robot helper. Futurologists predict that many homes will have robots in the future. Scientists today are starting to build friendlier, more sophisticated robots - ones that people will feel more comfortable having around in the house. They will be able to show feelings with their faces, just like humans. Not only will they do work around the house such as cooking and cleaning, but they will also take care of children and the elderly.
How soon will this smart home be a reality? There’s a good chance it will be a part of your life in 25 or 30 years, perhaps sooner. Much of the technology is already here.
