One example is the smart watch, which can keep an eye on users' health. If it detects an abnormal heart rate, it will automatically call the emergency services and send the user's location. This has saved many lives, especially for elderly people living alone. Another useful technology is speech recognition. It helps people with disabilities communicate more easily. For example, people who cannot type can use speech recognition to send messages or control electronic devices. This technology is also used in customer service, where AI systems can understand and respond to users' questions quickly. 3D printers are changing how things are made. In some hospitals, 3D printers are used to create custom-made parts for patients, such as artificial hands. This makes treatment more effective and reduces the cost of medical care. Digital payment methods are also becoming more popular. With digital wallets and QR codes, people can pay for things without carrying cash. This is not only convenient but also safer, as it reduces the risk of losing money. However, it's important to protect digital wallets with strong passwords to prevent theft. 1.
