Touch-Based Text Entry Using Hidden Markov Modeling

摘要

Described techniques enable a computing system to receive character string input (e.g., words, numbers, mathematical expressions, symbolic strings, etc.) by detecting and interpreting an input movement across a user-interface. A touch-based computing system may, for instance, detect an input movement by tracking the path of a pointing element (e.g., a stylus or finger) as it is dragged across a contact-sensitive input surface (e.g., a touch-sensitive screen or external touch pad). Then, the system may interpret the detected input movement using Hidden Markov Modeling.
