Scrolling Control Logic for Display Edge Recognition

Solution Overview

Problem

Users may struggle to recognize the boundary of a display target when its display state changes in response to user operations, especially when the change conditions are similar between the boundary and non-boundary areas.

Innovation Solution

An information processing apparatus and method that includes a control unit to manage the display of images with edges, scrolling through the image from one edge to another in response to user inputs, and continuing scrolling past the edges to display the opposite edge, while using boundary information to restrain and display the target based on specific operation conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the display state changes uniformly across all regions, then the operation logic is simple, but the user cannot recognize the boundary of the display target

Engineering Contradiction:

Improveoperation logic complexityVSAvoidboundary recognition

Core Design Contradiction:

Device complexityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies different display state change rules to different regions: the first region (boundary area) displays the target in a first state, while the second region (non-boundary area) displays the target in a second state. This local differentiation allows users to recognize boundaries through visual cues while maintaining simple operation logic within each region.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The display region is segmented into a first region and a second region based on boundary information. This segmentation enables the system to apply different display states to different areas, making boundaries visible to users without complicating the overall operation logic.

Inventive Principle:

Principle #1Segmentation

2Reliability

If scrolling stops at the boundary, then the display target remains within bounds, but the user cannot navigate beyond the edge

Engineering Contradiction:

Improvedisplay boundary controlVSAvoidnavigation continuity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Instead of stopping scrolling at the boundary, the patent inverts the expected behavior by continuing to scroll beyond the boundary. When scrolling reaches the end of the display target, it automatically wraps around to display the beginning, enabling continuous navigation without interruption while still maintaining boundary control through the wrapping mechanism.

Inventive Principle:

Principle #13The other way round (Inversion)

3Stability of the object's composition

If the same operation triggers the same display change throughout, then the system is consistent, but boundary-specific operations cannot be distinguished

Engineering Contradiction:

Improvesystem consistencyVSAvoidboundary-specific operation response

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system maintains consistency by using uniform operation inputs (scrolling operations) but achieves adaptability by applying different display state changes based on location. The same scrolling operation triggers a first display state change in the boundary region and a second display state change in the non-boundary region, allowing boundary-specific responses while maintaining operational consistency.

Inventive Principle:

Principle #3Local quality

AI summary

An apparatus that includes circuitry that controls a display to display an image having a first edge and a second edge, the second edge on an opposite side of the image from the first edge, scroll through the image from the first edge to the second edge in response to a first user input, and continue scrolling past the second edge in response to a second user input, and the second user input is different than the first user input.
