Display Device Character Input Field Storage and Restoration Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices require users to re-input characters when they incorrectly input into the wrong character input field, leading to an unfriendly user experience due to the need to delete previously entered characters and re-enter them in the correct field.
Innovation Solution
A display device with a display control section that designates a character input field for input operations, stores deleted characters when all are cleared from a wrong field, and displays these characters in another field when the correct field is selected, allowing seamless continuation of input without re-typing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display device displays multiple character input fields for user input, then the device can accept various types of information (user ID, password, etc.), but when users input characters into the wrong field, they must delete all characters and re-input them, which reduces ease of operation
Solution Approach 1:
The system performs preliminary action by storing deleted characters in memory before the user needs to re-input them. When characters are deleted from an incorrect input field, the system automatically saves these characters and later restores them to the correct input field, eliminating the need for users to re-type the same characters manually.
Solution Approach 2:
The system introduces an intermediary mechanism (character storage and restoration function) between the deletion action and the final input state. This intermediary stores the deleted characters temporarily and facilitates their automatic transfer to the correct input field, acting as a mediator that prevents complete data loss and reduces user effort.
2Ease of operation
If the display device allows free movement of input focus between multiple character input fields, then users can navigate between fields easily, but users may accidentally input into the wrong field, requiring deletion and re-input of characters
Solution Approach 1:
The system implements feedback by monitoring input operations and providing corrective actions automatically. When the system detects that characters are deleted from an input field (indicating possible wrong-field input), it triggers a restoration process that transfers the characters to the intended correct field, thereby providing feedback that corrects the input error without user intervention.
Solution Approach 2:
The system performs self-service by automatically detecting and correcting input errors without requiring user awareness or manual correction. The character restoration function operates autonomously to transfer deleted characters to the correct input field, making the system self-correcting and reducing the burden on users to manually verify input destinations.

AI summary
A display device includes a display section, a display control section, an acceptance section, and a storage section. The display control section allows the display section to display an input screen including a plurality of character input fields. When all characters displayed in a character input field designated as a character input destination are deleted by a sequence of character deletion operations, the display control section allows the storage section to store the deleted characters. Then, when the acceptance section accepts an operation for canceling designation of the character input field as the character input destination, the display control section allows the display section to display, in another of the plurality of character input fields, the characters stored in the storage section.
