1. A data entry device comprising:
- a digitizer having a plurality of key input regions for receiving stroke inputs, each key input region having a plurality of characters indicated thereon, the digitizer having an output providing x and y co-ordinate data for stroke inputs;
a computational device coupled to the digitizer, the computational device accepting x and y co-ordinate data from the digitizer and identifying a key input region in which a stroke is entered and measuring parameters of the entered stroke; and
a memory coupled to the computational device, the memory having stored therein correlation information correlating stroke parameters for a given key input region with characters indicated on that input region.

Abstract
A data entry device with a digitizer (20) having key input regions (21) for receiving stroke inputs. Key input region have multiple characters indicated on them. The digitizer has an output providing x and y co-ordinate data for stroke inputs. A computational device (30) accepts x and y co-ordinate data from the digitizer, identifies a key input region in which a stroke is entered and measures parameters of the entered stroke. A memory (31) has correlation information correlating stroke parameters for a given key input region with characters indicated on that input region.
