Document Reading Device Selective Sound Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional document reading devices provide unnecessary and cumbersome guidance to users who understand the operations correctly, leading to a meddlesome experience, as they unconditionally execute sound guidance for all document reading operations regardless of the user's understanding or the specific device state.
Innovation Solution
A document reading device with a notification unit and a notification control unit that selectively outputs guidance based on the device state, prompting the user only when the device is not in the required state for a specific operation, such as the multiple cropping function, after a predetermined period has elapsed since the operation was selected, thus avoiding unnecessary guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sound guidance is unconditionally executed for all document reading operations, then users who do not understand the operations receive necessary guidance, but users who understand the operations correctly experience meddlesome and cumbersome guidance
Solution Approach 1:
The system changes the parameter of guidance output based on the detected device state. When the device state matches the required state for the selected function, guidance output is suppressed; when it doesn't match, guidance is output after a predetermined period. This dynamic parameter change resolves the contradiction by adapting guidance behavior to the actual operational context.
Solution Approach 2:
The notification control unit continuously monitors the device state and compares it with the required state for the selected document reading function. This feedback mechanism allows the system to intelligently determine whether guidance should be output, ensuring that guidance is provided only when necessary and suppressing it when the user already understands the correct operation.
2Reliability
If guidance is output immediately when a document reading function is selected, then users receive prompt assistance, but the guidance may be meddlesome if the user already knows the correct operation
Solution Approach 1:
The system performs a preliminary check of the device state before outputting guidance. By detecting whether the device is already in the required state for the selected function, the system可以避免输出不必要的指导信息，从而减少用户的时间损失，同时确保在需要时及时提供指导。
Solution Approach 2:
The notification control unit uses periodic timing to determine when to output guidance. Instead of immediate output, it waits for a predetermined period after the function is selected, then checks the device state. This periodic approach allows users who understand the operation to complete quick actions without interruption, while still providing guidance to those who need it.

AI summary
A document reading device that is capable of selectively designating a document reading process includes a sound output unit that gives notification of information needed for a document reading process that has been selected and a notification control unit that controls output from the sound output unit. When a specific document reading process has been selected, the notification control unit exercises control so that in a case where a device state of the document reading device is not the specific device state, notification information that prompts for the specific device state is outputted by the sound output unit after a predetermined period of time has elapsed since the specific document reading process was selected and so that in a case where the device state of the document reading device is the specific device state, notification information whose content prompts for the specific device state is not outputted by the sound output unit.
