  • Patent number: 11042291
    Abstract: A method and an apparatus input test in a touch screen terminal. The method comprises designating a certain region on a keyboard interface picture, not permitting text input through a keyboard when touch drag started from the designated region is sensed and acquiring a path of the touch drag, acquiring a path of following touch drag when at least the one or more following touch drag are sensed, and reading out at least the acquired one or more paths by cursive character recognition, deducing a character, determining the deduced character as an input target, and permitting the text input through the keyboard.
