Voice Input Control for Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses often perform unnecessary processing when accepting voice instructions from users not using the device, leading to inefficiency in voice instruction functionality.
Innovation Solution
An image forming apparatus that only accepts voice instructions when the user is holding and using the device with both hands, incorporating a measurement device that measures blood pressure and pulse, and a processing program that activates voice input only when necessary, such as for inexperienced users or during measurement tasks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image forming apparatus accepts voice instructions from any user, then the convenience of voice input is improved, but unnecessary processing occurs when users not using the device provide instructions
Solution Approach 1:
The system performs preliminary detection to determine whether a user is actively using the image forming apparatus before accepting voice instructions. The detector detects user presence and usage state in advance, and the controller selectively enables voice input acceptance only when a user is actively using the device, thereby preventing unnecessary processing from bystanders while maintaining convenience for actual users
2Ease of operation
If voice input function is always active, then user convenience is improved, but device complexity increases due to continuous monitoring requirements
Solution Approach 1:
The voice input acceptance state is made dynamic rather than static. The controller dynamically adjusts the voice input function based on real-time detection results, enabling voice input only when the detector confirms active user usage. This dynamic approach maintains input flexibility when needed while reducing system complexity by not requiring continuous monitoring in all states

AI summary
An image forming apparatus to be used together with equipment to be used by a user with both hands, the image forming apparatus includes: an acceptor that does not accept, by voice, an instruction for processing to be performed by the image forming apparatus before the user holds the equipment but accepts, by the voice, the instruction while the equipment is being used with both of the hands.
