Touch Panel Display Dynamic Key Visibility for Copy Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for operation consoles with touch-panel displays face a trade-off between operability and visibility, particularly when switching between preview images and virtual ten keys, leading to user uncertainty and increased risk of errors during setting changes.
Innovation Solution
An operation console that prioritizes the display of image data over virtual ten keys, allowing users to input settings without erasing the keys, with a request key to toggle key visibility, ensuring clear understanding of which image settings are being changed, and automatic key hiding when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the ten keys are displayed on the screen image, then the user can input settings using the virtual ten keys, but the usable display area becomes smaller and the preview image cannot be confirmed clearly
Solution Approach 1:
The patent applies dynamics by making the display state of the ten keys changeable rather than fixed. The ten keys are displayed or hidden based on the operational context - displayed when setting input is needed, hidden when preview image confirmation is the priority. This dynamic switching resolves the contradiction by adapting the interface to the user's current task needs.
Solution Approach 2:
The patent uses preliminary action by detecting user behavior in advance and proactively changing the display state. When the system detects that the user is likely to need preview image confirmation, it automatically hides the ten keys beforehand, preventing the display area reduction issue before it occurs.
2Area of stationary object
If the ten keys are hidden when not in use, then the display area is maximized for preview image confirmation, but the user cannot immediately change settings using the ten keys
Solution Approach 1:
The patent applies feedback by continuously monitoring user behavior and system state to determine when the ten keys should be displayed or hidden. The display control device receives feedback from user operations and automatically adjusts the ten keys visibility accordingly, ensuring both maximum display area and immediate accessibility when needed.
Solution Approach 2:
The system uses self-service by automatically managing the display state of the ten keys without requiring manual user intervention. The display control device autonomously decides when to show or hide the ten keys based on detected user behavior patterns, eliminating the need for users to manually toggle the display state.
3Area of stationary object
If the user has to erase the ten keys to confirm the preview image, then the display area is maximized, but the operability is reduced and user convenience is compromised
Solution Approach 1:
The system performs self-service by automatically managing the visibility of the ten keys based on user behavior detection. The display control device autonomously hides the ten keys when preview image confirmation is needed and displays them when setting input is required, eliminating the need for manual erasure operations by the user.
4Ease of operation
If the user wishes to change settings and has the ten keys displayed, then the user can input settings, but the user feels uncertain on which preview image the process is being done
Solution Approach 1:
The patent applies dynamics by making the ten keys visibility conditional rather than static. The ten keys are displayed only when setting input is detected as needed, and hidden when preview image confirmation is the primary task. This dynamic behavior ensures that when the ten keys are visible, the user is in setting mode, and when they are hidden, the user is in preview confirmation mode, eliminating contextual uncertainty.
Data Source
AI summary
In order to provide an operation console having superior operability and visibility, a touch-panel display includes a display panel displaying a copy mode basic screen image with virtual keys, and a touch-panel receiving an input operation to the virtual keys. On the copy mode basic screen image, a group of virtual ten keys for inputting the number of copies are displayed. When image data is input by a document reading unit, the touch-panel display causes a preview image based on the image data to be displayed with higher priority than the group of virtual ten keys, in the copy mode basic screen image.
