Smart Scroll is a feature found in some devices and applications that allows users to navigate content more easily. It uses sensors to detect the user's eye movement or hand gestures, enabling scrolling without the need to touch the screen. This can enhance the reading experience by allowing users to focus on the content without interruptions. The technology behind Smart Scroll often involves motion sensors and cameras that track how the user interacts with the device. By automatically adjusting the scroll speed based on the user's gaze or gestures, it provides a more intuitive way to browse through long articles, web pages, or documents.
