Meta, the company behind Facebook, Instagram, and WhatsApp, has introduced a new wristband that allows users to control computers and smartphones using just hand gestures or even thoughts. This device looks like a thick smartwatch but doesn’t tell time. Instead, it reads the electrical signals in your muscles when you move or think about moving your fingers.
By simply tapping your thumb and finger, you can open an app on your computer. A small wrist movement can move your cursor, and writing in the air can type letters on your phone. The wristband uses a technology called EMG (electromyography), which reads muscle signals from the skin. Meta has trained the system using data from thousands of people and powered it with artificial intelligence to understand muscle movements accurately.
Unlike brain implants being developed by companies like Elon Musk’s Neuralink, Meta’s wristband doesn’t need surgery. Anyone can wear it and start using it. Over time, users can even control their devices with just the intention to move, without physically moving.
The device could be especially helpful for people with disabilities. Tests at Carnegie Mellon University show that even those with limited movement can use the wristband to operate computers, because it picks up what the brain wants to do through slight muscle activity.
Meta plans to add this technology into future products, like smart glasses. According to the developers, this innovation could change how we interact with technology—making it faster, easier, and more natural—without needing to touch screens or keyboards. The device doesn’t read your mind, but it does sense what you’re planning to do before you even move.
