...(Is there a technology that reads the movement of the eyes with a camera or the like and scrolls the screen of the smartphone?
:Yes, there is a technology that enables eye-tracking on smartphones to scroll the screen based on the movement of the user's eyes. This feature is often referred to as "eye-scrolling" or "gaze-scrolling." The technology relies on using the front-facing camera of the smartphone to track the position and movement of the user's eyes. Eye-tracking technology has beenimplemented in various ways by smartphone manufacturers and software developers to provide a more convenient and hands-free scrolling experience for users. When this feature is enabled, the device uses the front camera to monitor the user's eye movements, and when the user looks towards the bottom or top of the screen, the software automatically scrolls the content in that direction.
However, it's important to note that the effectiveness and availability of eye-scrolling technology may varyacross different smartphone models and brands. Some smartphones may have this feature built into their operating systems or user interfaces, while others may require third-party apps or software to enable eye-scrolling functionality.
As with any technology that involves user privacy and data collection, eye-scrolling features typically come with opt-in settings, ensuring that users have control over whether they want to use this functionality or not. Additionally, advancements in technology mayhave occurred after my last knowledge update in September 2021, so it's possible that there have been further developments in eye-scrolling technology since then. openai_com/blog/chatgpt
