Touch Display Status View Expansion Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of image processing apparatuses face issues where the status view area is either not expanded when relevant information is needed or expanded when irrelevant information is displayed, leading to unnecessary manipulations due to accidental finger release during sliding operations.
Innovation Solution
An image processing apparatus with a touch-enabled display and memory that stores reference information to determine relevance, allowing the display controller to automatically expand the status view area if information is relevant and restore it if irrelevant, even before or after the sliding manipulation is completed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If automatic sliding is implemented based on finger position (center threshold), then full-screen expansion can be achieved, but users may accidentally trigger expansion or restoration when releasing finger before reaching center
Solution Approach 1:
The system continuously monitors the sliding distance and provides feedback to the control unit. When the sliding distance exceeds the threshold, the control unit confirms the user's intent to expand the status view area. This feedback mechanism prevents accidental triggers by requiring the user to complete the sliding action beyond the threshold point.
Solution Approach 2:
The system prepares the expansion state in advance by monitoring the sliding distance from the initial position. When the sliding distance reaches the threshold, the system is ready to execute the expansion action, ensuring that only intentional sliding gestures trigger the expansion while preventing accidental triggers.
2Loss of information
If status view area is expanded to full-screen, then detailed information becomes accessible, but users may see irrelevant information when accidentally triggering expansion
Solution Approach 1:
The control unit monitors the sliding distance and only executes the expansion action when the threshold is exceeded. This feedback mechanism ensures that the status view area is expanded only when the user intentionally completes the sliding gesture, preventing accidental expansion that would display irrelevant information and require additional manipulation to restore.
3Reliability
If status view area is restored when sliding distance is insufficient, then accidental triggers are prevented, but users fail to obtain needed information when releasing finger before center
Solution Approach 1:
The system prepares the expansion state in advance by monitoring the sliding distance from the initial position. When the sliding distance reaches the threshold, the system is ready to execute the expansion action, ensuring that only intentional sliding gestures trigger the expansion while preventing accidental triggers.
Solution Approach 2:
The control unit continuously monitors the sliding distance and provides feedback on whether the threshold is met. This feedback mechanism prevents premature restoration by only executing the restoration action when the sliding distance is confirmed to be insufficient, ensuring that intentional expansions are not accidentally cancelled.

AI summary
An image processing apparatus includes: a touch-enabled display that is capable of displaying a first screen and a second screen smaller than the first screen, the second screen showing information, the second screen to be expanded with a user sliding manipulation; a memory that stores reference information determining which information on the second screen is relevant and irrelevant to the first screen; a judgment portion that judges whether or not the information on the second screen is relevant to the first screen on the basis of the reference information stored on the memory; and a display controller that expands the second screen even without the sliding manipulation being completely finished if the information on the second screen is relevant to the first screen and that restores the second screen to the previous state upon finish of the sliding manipulation if the information on the second screen is irrelevant to the first screen.
