Swype

Swype is a virtual keyboard for touchscreen smartphones and tablets originally developed by Swype Inc. where the user enters words by sliding a finger or stylus from the first letter of a word to its last letter, lifting only between words. It uses error-correction algorithms and a language model to guess the intended word. It also includes a predictive text system, handwriting and speech recognition support. Swype was first commercially available on the Samsung Omnia II running Windows Mobile, and was originally pre-loaded on specific devices.
