Faster Text Entry on Mobile Devices Through User-Defined Stroke Patterns

A mobile computing device that enables text entry through shorthand stroke patterns, the mobile computing device comprising:

• at least one processor;
• at least one non-transitory computer-readable medium that stores:
• data that describes a plurality of shorthand stroke patterns that have previously been defined by a user of the mobile computing device;
• and
• a plurality of output text strings respectively associated with the plurality of shorthand stroke patterns;
• and
• a shorthand pattern recognizer implemented by the at least one processor, the shorthand pattern recognizer configured to:
• receive data that describes an input stroke pattern entered by the user;
• and
• identify one of the plurality of shorthand stroke patterns as a matched shorthand stroke pattern to which the input stroke pattern corresponds;
• wherein, in response to identification of the matched shorthand stroke pattern by the shorthand pattern recognizer, the mobile computing device is configured to enter the output text string associated with the matched shorthand stroke pattern into a text entry field.

At least one non-transitory computer-readable medium that stores instructions that, when executed by at least one processor, cause the at least one processor to:

• receive data descriptive of an input stroke pattern entered by a user;
• input the data descriptive of the input stroke pattern into a shorthand pattern classifier;
• receive as output from the shorthand pattern classifier an identification of one of a plurality of shorthand stroke patterns as a matched shorthand pattern to which the input stroke pattern corresponds, the plurality of shorthand stroke patterns previously defined by the user, a plurality of output text strings respectively associated with the plurality of shorthand stroke patterns;
• and
• in response to receiving the identification of the matched shorthand pattern, enter the output text string associated with the matched shorthand pattern into a text entry field.
