You probably use Augmented Reality (AR) every day without realizing it. The fun filters on Instagram or TikTok that put virtual glasses or hats on your head are a form of AR. This technology, which adds digital images to your view of the real world, is now moving beyond social media and into the world of online shopping.

Imagine you're shopping online for a new jacket. Instead of just looking at photos, you can use your phone’s camera to see how that jacket looks on you in real-time. This is 'virtual try-on'. It makes online shopping much more interactive and can help you decide if an item is right for you. For many shoppers, this is incredibly convenient because it solves one of the biggest problems of e-commerce: not being able to try before you buy.

However, the technology is not yet perfect. Sometimes, the virtual clothes don't fit the body's shape accurately, which can lead to a poor user experience. Because of these technical challenges and the cost of development, many companies, including some in Vietnam, are still hesitant to fully adopt AR. They are testing it with smaller items like makeup or accessories first, rather than entire clothing lines.

Despite these obstacles, the future of AR in retail looks promising. As technology improves, virtual try-on experiences will become more realistic and reliable. For teenagers who have grown up with digital technology, using AR to shop for clothes online might soon feel as normal as using a filter on a selfie. It represents a significant shift in how we interact with the products we buy online.

While companies claim they only store data after a wake word is detected, security breaches and accidental activations have shown this isn't always foolproof. Furthermore, the collected data is often used for targeted advertising, (38) __________. Users must weigh the benefits of a helpful digital assistant against the potential risks, (39) __________. It's crucial to understand the privacy settings and to be aware of the trade-offs, (40) __________.
