What is palm rejection?

Palm rejection is a technology that allows touchscreen devices to distinguish between intentional touch inputs from fingers or styluses, and unintentional touch inputs from palms or other parts of the hand. This technology is particularly useful for devices that have large touchscreens, such as tablets and smartphones, where accidental palm touches can interfere with the user's intended actions.

Palm rejection works by using algorithms to analyze the size, shape, and pressure of touch inputs on the screen. By determining whether a touch input is likely to be intentional or unintentional, the device can effectively ignore the latter while responding to the former.

Palm rejection technology has become increasingly common in modern touchscreen devices, and is often integrated into the operating system or software of the device. This allows users to interact with the touchscreen more comfortably and accurately, without the frustration of accidental palm touches disrupting their experience.

Overall, palm rejection technology helps to improve the usability and functionality of touchscreen devices, making them more intuitive and easier to use for users of all ages and skill levels.
