System and method for recognizing handwritten stroke input

A method for recognizing content associated with handwritten stroke input to a computing device, the method comprising:

• receiving a user input via an interactive key layout displayed on an interface surface of a computing device, wherein the user input comprises one of a handwriting input, a typing input, or a stroke-typing input;
• detecting a handwritten stroke based on the received user input;
• determining a sequence of points forming a path of the detected handwritten stroke;
• identifying a interactive key sequence of the interactive key layout disposed on the path of the detected handwritten stroke;
• identifying, for each key of the interactive key sequence, a plurality of points from the sequence of points that are located within the key;
• determining, for each key of the interactive key sequence, a reference point located at a centroid of the plurality of points;
• determining a sequence of the reference points associated with the interactive key sequence of the interactive key layout;
• identifying a reference stroke of the detected handwritten stroke based on the determined sequence of the reference points associated with the interactive key sequence;
• assigning one or more probability scores to one or more candidate characters associated with each key of the interactive key sequence;
• and
• causing recognition of one or more sequences of characters by applying a language model in accordance with the assigned probability scores.

A non-transitory computer readable medium having a computer readable program code embodied therein, said computer readable program code adapted to be executed to implement a method for recognizing content associated with handwritten stroke input to a computing device, the computing device comprising a processor, a memory and at least one non-transitory computer readable medium for recognizing content under control of the processor, the method comprising:

• receiving a user input via an interactive key layout displayed on an interface surface of a computing device, wherein the user input comprises one of a handwriting input, a typing input, or a stroke-typing input;
• detecting a handwritten stroke based on the received user input;
• determining a sequence of points forming a path of the detected handwritten stroke;
• identifying a interactive key sequence of the interactive key layout disposed on the path of the detected handwritten stroke;
• identifying, for each key of the interactive key sequence, a plurality of points from the sequence of points that are located within the key;
• determining, for each key of the interactive key sequence, a reference point located at a centroid of the plurality of points;
• determining a sequence of the reference points associated with the interactive key sequence of the interactive key layout;
• identifying a reference stroke of the detected handwritten stroke based on the determined sequence of the reference points associated with the interactive key sequence;
• assigning one or more probability scores to one or more candidate characters associated with each key of the interactive key sequence;
• and
• causing recognition of one or more sequences of characters by applying a language model in accordance with the assigned probability scores.
