Updating Guidance for Layered Operation Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies for image forming apparatuses with layered operation screens fail to provide correct guidance when operation buttons are added or deleted, disrupting the consistency of the guidance function.
Innovation Solution
A display apparatus with a recognizing unit to detect changes in operation objects, an update unit to adjust guidance information based on the layered structure, and a checking unit to confirm operator instructions, ensuring that guidance reflects the updated configuration of operation screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If operation buttons are added or deleted in layered operation screens, then the operation screen configuration is updated, but the guidance information becomes inconsistent with the current screen state
Solution Approach 1:
The system automatically detects changes in operation buttons (addition or deletion) and feeds this information back to update the guidance information accordingly. The recognizing unit monitors button changes and triggers the update unit to regenerate guidance information that matches the current screen configuration, ensuring consistency without manual intervention.
Solution Approach 2:
The system performs preliminary updates to guidance information before the operator encounters inconsistent guidance. By proactively detecting button changes and updating guidance information in advance, the system prevents the occurrence of inconsistent guidance states rather than correcting them after detection.
2Reliability
If guidance information is updated for every operation button change, then guidance consistency is maintained, but system complexity increases
Solution Approach 1:
The system performs self-updating of guidance information through automated detection and regeneration processes. The recognizing unit autonomously identifies button changes and triggers the update unit to regenerate guidance information without requiring external intervention or complex manual update procedures, simplifying the overall system structure.
Solution Approach 2:
The guidance information is designed to be dynamic rather than static, automatically adapting to changes in operation button configuration. The system structure allows guidance information to be regenerated on-demand based on current screen state, providing flexibility without requiring a permanently complex update mechanism.
3Ease of operation
If multiple operation screens have layered structure, then functional organization is improved, but tracking guidance updates across layers becomes difficult
Solution Approach 1:
The update unit is designed with universal functionality to handle guidance information updates across all layers of the operation screen hierarchy. A single update mechanism processes guidance information for multiple layers simultaneously, eliminating the need for separate tracking systems for each layer and simplifying the overall update process.
Solution Approach 2:
The system segments the layered operation screens while maintaining a unified guidance update mechanism. Each layer's guidance information can be independently updated when needed, but the update unit manages all layers through a coordinated process, making tracking feasible through modular yet integrated handling.

AI summary
A display apparatus that switches and displays a plurality of operation screens each including an operation object selectable by an operator and having a layered structure includes a storage unit which stores information on guidance of prompting an operator to select a predetermined operation object, a recognizing unit which recognizes that an operation object is added or deleted, and an update unit which updates information on guidance in response to a relation between an operation screen to/from which the operation object is added or deleted and an operation screen positioned higher or lower than the operation screen such that content of the guidance provided on the basis of the information reflects configurations of the plurality of operation screens after addition or deletion of the operation object, when the operation object is added or deleted.
