This paper presents Restorable Backspace, an input helper for mistyping correction. It stores characters deleted by backspace keystrokes, and restores them in the retyping phase. We developed Restoration algorithm that compares deleted characters and retyped characters, and makes a suggestion while retyping. In a pilot study we could observe the algorithm work as expected for most of the cases. All participants in the pilot study showed satisfaction about the concept of Restorable Backspace.
