Image Forming Interface With Context-Based Voice Input Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face security and accuracy issues with voice inputs, as user information such as IDs and passwords can be inadvertently heard by surroundings, and voice input accuracy is not guaranteed for certain instructions.
Innovation Solution
An image forming apparatus with a controller that switches between manual input dedicated mode and voice input possible mode, prohibiting voice input for sensitive information and ensuring accurate manual input for secure operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice input is allowed for all functions, then ease of operation is improved, but security deteriorates due to potential leakage of sensitive information
Solution Approach 1:
The patent applies local quality by differentiating input methods based on the specific function or screen being accessed. Voice input is permitted for general functions but prohibited for screens handling sensitive information such as user IDs and passwords. This selective approach maintains ease of operation for routine tasks while ensuring security for critical operations.
2Productivity
If voice input is used for all inputs, then productivity is improved, but reliability deteriorates due to potential input accuracy issues
Solution Approach 1:
The system applies local quality by assessing the suitability of voice input for each specific function or input field. For functions where voice recognition may compromise accuracy (such as precise data entry or critical commands), manual input is required. For other functions, voice input accelerates operation. This ensures reliability is maintained where needed while productivity is enhanced where appropriate.
3Object-affected harmful factors
If voice input is prohibited for sensitive information screens, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements dynamics by making the input method flexible and context-dependent. The system dynamically switches between accepting voice input and requiring manual input based on the current screen or function. This dynamic adaptation maintains security for sensitive operations while preserving ease of operation for non-sensitive tasks, avoiding a blanket prohibition that would unnecessarily reduce usability.
4Reliability
If manual input is required for all operations, then reliability is improved, but productivity deteriorates
Solution Approach 1:
The system applies dynamics by allowing the input method to change based on operational context. Manual input is required for sensitive or accuracy-critical operations to ensure reliability, while voice input is permitted for routine or less critical functions to maintain productivity. This dynamic selection optimizes both reliability and productivity across different operational scenarios.

AI summary
An image forming apparatus includes: a receiver that receives a manual input instruction via an operation device and a voice instruction via a microphone; and a controller that executes a job on the basis of setting received by the receiver. The controller performs switching between a manual input dedicated mode in which only a manual input instruction is received by the receiver and a voice input possible mode in which a voice input and a manual input instruction are received by the receiver, and when an operation screen for receiving an input of information, an input of which through a voice instruction is prohibited in advance, is displayed on a display device by a display controller, the controller performs switching to the manual input dedicated mode.
