US Patent 7817858 Communication terminal

It is shown how to select and insert a non-textual, e.g. a smiley, into an application such as a chat application in a communication terminal. A smiley insertion area in the form of a hand writing input area is displayed under the control of a user interface application. After recording that a stylus, or similar device, has been used in drawing on the touch sensitive display, the drawing is matched in an interpretation process against a pattern library consisting of smileys and other non-textual symbols. After a successful match, the smiley symbol is appended to the text that is being input.
