Image Display Scroll Boundary Feedback via Slider Color Change
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image display devices with touch panels face difficulties in indicating when an image has reached its boundary, leading to degraded user operability as it is hard to recognize if the image has been scrolled to the end or not.
Innovation Solution
An image display device with a display control unit that scrolls the image and regulates the scroll amount to prevent the image from leaving the display area, while changing the display mode of the peripheral area, such as the scroll bar's slider, to visually indicate the end of the image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image is scrolled according to the detected scroll operation, then the image can be moved to display different content, but it becomes difficult to recognize whether the image has reached the boundary or if the scroll operation is not recognized
Solution Approach 1:
The patent changes the display color or appearance of the scroll bar slider to indicate boundary conditions. When the image reaches its boundary, the slider's color or visual state changes to provide feedback to the user, solving the problem of boundary recognition during scrolling operations.
Solution Approach 2:
The patent implements visual feedback through the scroll bar slider that continuously informs the user about the scrolling state. The slider's position and appearance provide real-time feedback about whether the image is at the boundary, resolving the information loss about boundary conditions.
2Reliability
If the scroll amount is regulated to prevent the image from leaving the display area, then the image boundary is maintained within view, but the user cannot recognize that further scrolling is possible or has reached the limit
Solution Approach 1:
The patent uses color or appearance changes of the slider to communicate scroll status. When the image reaches the boundary and further scrolling is regulated, the slider's visual state changes to clearly indicate to the user that the boundary has been reached, maintaining both reliable boundary control and user recognition.
Solution Approach 2:
The scroll bar slider acts as an intermediary between the image content and the user. It translates the complex scroll position and boundary conditions into simple, recognizable visual signals, allowing users to understand scroll status without directly observing the image boundaries.
3Loss of information
If the display mode of the peripheral area is changed to indicate the end of the image, then user recognition of the boundary is improved, but the device complexity increases
Solution Approach 1:
The patent employs color or appearance changes of existing UI elements (the scroll bar slider) to convey boundary information. This approach provides effective boundary indication without requiring additional hardware components or complex display mechanisms, thus minimizing the increase in device complexity.
Solution Approach 2:
The scroll bar slider serves multiple functions: it indicates scroll position, controls scrolling operations, and now also communicates boundary conditions through appearance changes. This multi-functionality reduces the need for separate indicators, thereby limiting the increase in device complexity while improving boundary information delivery.

AI summary
To provide an image display device and an image display method capable of causing an image displayed on a display device to be visually recognized without degrading the operability of the user. A scroll amount of an image displayed in an image display area is specified according to an operation of scrolling the image displayed in the image display area, the scroll amount is regulated so that the image displayed in the image display area is not out of the image display area if the image displayed in the image display area is scrolled to be out of the image display area when the image displayed in the image display area is scrolled according to the specified scroll amount, and a display mode of at least a portion of a peripheral area of the image display area is changed.
