System and method for recognizing geometric shapes

A method for providing geometric shape recognition for at least one input stroke on a computing device, the computing device comprising a processor and at least one non-transitory computer readable medium under control of the processor, said method comprising:

• recognizing, by the at least one non-transitory computer readable medium, at least one primitive that corresponds to at least one input stroke;
• applying, by the at least one non-transitory computer readable medium, at least one constraint to the at least one primitive, wherein the at least one constraint and at least one primitive are applied on a vector component level;
• and
• providing, by the at least one non-transitory computer readable medium, an output based on the application of the at least one constraint to the at least one primitive,
• wherein if the at least one constraint comprises multiple constraints, the multiple constraints are applied to the at least one primitive based on a priority order, wherein the priority order comprises constraints maintaining the at least one primitive's integrity, constraints implicit in the at least one primitive, and constraints defined by a gesture.

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 providing geometric shape recognition for at least one input stroke, said method comprising:

• preprocessing at least one input stroke;
• analyzing the preprocessed the at least one input stroke to determine whether the at least one input stroke is a gesture:
• wherein if the at least one input stroke is not a gesture:
• recognizing at least one primitive that corresponds to the at least one input stroke;
• applying at least one constraint to the at least one primitive, wherein the at least one constraint and the at least one primitive are applied on the vector component level;
• wherein if the at least one input stroke is a gesture, the gesture provides at least one further constraint to an output based on the application of the at least one constraint to the at least one primitive, wherein the at least one constraint and the at least one primitive are applied on the vector component level;
• and
• providing an output based on the application of the at least one constraint to the at least one primitive,
• wherein if the at least one constraint comprises multiple constraints, the multiple constraints are applied to the at least one primitive based on a priority order, wherein the priority order comprises constraints maintaining the at least one primitive's integrity, constraints implicit in the at least one primitive, and constraints defined by a gesture.
