Abstract
An electronic device having a handwritten mathematical formula recognition function includes a display unit with a touch panel. When a recognition-assisting information input module inputs recognition-assisting information for handwritten data to be recognized in response to a user's operation, the handwritten data input on the touch panel is recognized by a handwritten mathematical formula recognition module as an element of a mathematical formula, based on the recognition-assisting information input from the recognition-assisting information input module. The mathematical formula recognized by the handwritten mathematical formula recognition module is displayed on the display unit in a text format by a mathematical formula output module.
