Gesture Typing

A text entry method on touchscreen devices where the user enters a word by continuously gliding their finger from letter to letter on a virtual keyboard without lifting it, rather than tapping each key individually. The continuous trace is interpreted by a statistical decoder that matches the gesture shape against word templates to predict the intended word. Gesture typing was introduced in 2004 and is now available in major keyboard apps including Google Gboard and Microsoft SwiftKey. Research shows gesture typing is particularly promising for older adults because it eliminates the need to precisely target small keys (a major difficulty with age-related motor decline) and naturally encourages a word-level input strategy that benefits from auto-correction, unlike tap typing where users tend to correct errors letter by letter.
