Solution Overview

Problem

Users face difficulty in inputting character strings of words that have been previously presented by the suggestion function and selected, especially when these words are not registered in the dictionary database, leading to inefficiency when using applications without suggestion functions.

Innovation Solution

The character input device is configured to register character strings presented by the suggestion function in the dictionary database, allowing users to easily input previously selected words by associating the input character strings with their corresponding suggested words.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the suggestion function presents character strings not registered in the dictionary database, then the user can access more words, but it becomes difficult to input these words in applications without suggestion functions

Engineering Contradiction:

Improveaccess to suggested wordsVSAvoiddifficulty to input character strings

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system performs preliminary registration of suggested character strings into the dictionary database when the application is first launched or when suggestions are received. This preliminary action ensures that when users later want to input these suggested words in other applications, the character strings are already available in the dictionary database, eliminating the need for manual re-input and resolving the contradiction between accessing suggested words and ease of input operation.

Inventive Principle:

Principle #10Preliminary action

2Productivity

If the dictionary database is updated with suggested character strings, then input efficiency improves, but the device complexity increases

Engineering Contradiction:

Improvecharacter input efficiencyVSAvoiddictionary database management

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system automatically updates the dictionary database with suggested character strings without requiring manual intervention from the user. The character input device itself performs the registration operation when suggestions are received or when the application is launched, making the system self-servicing. This automation improves input efficiency while avoiding the complexity of manual database management, as the update process is transparent and requires no user configuration or maintenance effort.

Inventive Principle:

AI summary

A technique can be provided that allows a user to easily perform an operation to input a character string of a word that has been previously presented by a suggestion function and selected by the user. A character input device includes: an output unit configured to output a first character string to an application program having a suggestion function; a detector configured to detect selection of a second character string that is presented in correspondence with the first character string by the application program; and a registration unit configured to register, in a dictionary database, the second character string that is detected, by the detector, to have been selected.
