Touch Panel Edge Detection Feedback for Movement Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing touch panels struggle to inform users how far a display object can be moved during operations like scrolling or dragging, making it difficult for users to understand the limits of movement.
Innovation Solution
The method involves displaying an image with a portion of an object and detecting movement of an operating member relative to the object's edge, modifying the image or object movement based on whether the edge is within the display region, to notify users when the object cannot be moved further.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a general touch panel is used to detect contact position, then the user can perceive the contact position, but it is difficult to grasp how far the display object can be moved during operation
Solution Approach 1:
The patent implements feedback by displaying an operating member that visually indicates the current position and movement range of the display object. When the edge of the display object reaches the display region boundary, the operating member provides visual feedback to inform the user that no further movement is possible, thus preventing information loss about movement limits.
Solution Approach 2:
The operating member serves as an intermediary element between the user and the display object. It translates the invisible movement range information into visible visual cues, allowing users to understand how far the display object can be moved without directly exposing the boundary conditions.
2Ease of operation
If the display object is moved continuously during operation, then the operation smoothness is improved, but the user cannot determine the movement limit
Solution Approach 1:
The operating member continuously provides visual feedback during the dragging operation, showing the user's finger position and the corresponding display object position. When the movement limit is approached, the operating member's visual state changes to indicate that the boundary has been reached, maintaining operation smoothness while informing the user of the limit.
Solution Approach 2:
The patent utilizes color changes in the operating member to convey different states. When the edge of the display object reaches the display region boundary, the operating member changes its visual appearance (e.g., color or brightness) to alert the user that the movement limit has been reached, providing intuitive visual cues without disrupting the smooth operation.

AI summary
A method is provided for modifying an image. The method comprises displaying an image, the image comprising a portion of an object; and determining if an edge of the object is in a location within the portion. The method further comprises detecting movement, in a member direction, of an operating member with respect to the edge. The method still further comprises moving, if the edge is not in the location, the object in an object direction corresponding to the detected movement; and modifying, if the edge is in the location, the image in response to the detected movement, the modified image comprising the edge in the location.
