Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If handwritten characters are generated character by character using conventional processing methods, then text recognition accuracy is maintained, but processing time increases and display delay occurs
Solution Approach 1:
The patent segments the text generation process into two distinct phases: first generation processing that extracts N-character strings from handwritten input for rapid display, and second generation processing that converts individual characters for accurate text recognition. This segmentation allows parallel processing paths that resolve the contradiction between speed and accuracy.
Solution Approach 2:
The patent performs preliminary action by extracting and displaying N-character strings immediately after handwritten input detection, before complete character-by-character recognition is finished. This preliminary display reduces perceived delay while the second generation processing continues in the background to ensure accuracy.
2Measurement precision
If character-by-character processing is used for handwritten input, then processing accuracy is maintained, but productivity decreases due to time delay
Solution Approach 1:
The processing system is segmented into two parallel pathways: rapid N-character string extraction for immediate productivity feedback, and meticulous character-by-character conversion for accuracy verification. This dual-path approach maintains accuracy while significantly improving perceived productivity.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining both generation processes simultaneously - the first generation provides continuous rapid output for productivity, while the second generation continuously refines accuracy, ensuring both goals are met without interruption.

AI summary
The present invention is to reduce a delay in displaying handwritten characters. An information processing apparatus includes: an input unit capable of detecting handwritten input; a display unit capable of displaying a trajectory of the handwritten input; a text recognition unit which recognizes text based on the handwritten input detected by the input unit; a prediction processing unit which predicts text candidates following the text based on the text recognized by the text recognition unit; a handwriting synthesis unit which synthesizes the text candidates predicted by the prediction processing unit into handwritten characters by combining first generation processing to generate handwritten characters based on tokens, each of which is a set of one or more handwriting strokes, collected from the handwritten input by a user, and second generation processing to generate handwritten characters based on a conversion model prepared in advance for converting text characters to handwritten characters; and a display processing unit which displays, on the display unit, the handwritten characters corresponding to the text candidates and synthesized by the handwriting synthesis unit.
