Gboard, Google's mobile keyboard app, incorporates several active and manual error correction features to enhance the typing experience.

In addition to these active features, Gboard also offers manual actions, such as grammar and spell checkers, to help users systematically repair committed words.

Gboard, Google's mobile keyboard app, addresses the 'fat finger' problem by using statistical decoding and incorporating various error correction features. These features include word completion, next-word predictions, active auto-correction (AC), and active key correction (KC). They work together to make typing easier by correcting errors and offering multiple word candidates in the suggestion bar or inline.
Additionally, Gboard uses post-correction (PC) to fix errors in the last one or more committed words. Users can also take additional manual actions and make selections to ensure a smoother typing experience. These features help reduce typing errors on small screens by providing accurate suggestions, correcting mistakes, and allowing users to type at a faster pace without worrying about making errors.

Gboard, Google's mobile keyboard app, operates on the principle of statistical decoding. This approach is necessary due to the inherent inaccuracy of touch input, often referred to as the 'fat finger' problem, on small screens. Statistical decoding helps correct errors and offers multiple word candidates in the suggestion bar or inline, as well as smart compose, making it easier for users to type.
