Solution Overview

Problem

Existing image display devices and image forming apparatuses face issues with varying operating feelings when rearranging icons, leading to user discomfort due to changes in touch position, causing stress and potential operation errors.

Innovation Solution

The image display device and image forming apparatus utilize a controller to receive and process touch operations, assuming a predetermined first position on the icon for rearrangement, ensuring consistent operating feelings by controlling the display position change based on the detected touch position, regardless of the actual touch location.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the display position of an icon is changed by allowing free movement upon touch, then the flexibility and adaptability of icon arrangement is improved, but the operating feeling becomes inconsistent depending on the touch position, causing user discomfort

Engineering Contradiction:
Improveicon arrangement flexibilityVSAvoidoperating feeling consistency
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent applies parameter changes by modifying the display position calculation based on the touch position. When an icon is touched, the system calculates a corrected display position that adjusts the icon's movement to ensure consistent operating feeling regardless of where the user touches the icon. This involves changing the position parameter dynamically based on touch coordinates while maintaining the flexibility of icon rearrangement.

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If the icon movement is controlled based on actual touch position, then the precision of position change is improved, but the operating feeling varies depending on touch location, leading to user stress and potential errors

Engineering Contradiction:
Improveposition change precisionVSAvoidoperation reliability
Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent implements feedback by detecting the touch position on the icon and using this information to calculate a corrected display position. The system provides feedback to the user through consistent icon movement behavior that depends on the touch position, ensuring that the operating feeling remains uniform. This feedback mechanism helps prevent user stress and operation errors by making the icon movement predictable and reliable regardless of touch location.

Inventive Principle:
Principle #23Feedback

AI summary

An image display device, an image forming apparatus (1), a display position changing method, and a program capable of unifying operating feelings at a time of an arrangement changing operation of icons are provided. An image display device has an operation receiver (20) that receives an operation of selecting and moving a part of a plurality of icon images (A1 to A9) displayed on a display screen as a movement source icon (A4), and a display position changer (100) that changes, when the operation is received, a display position of the movement source icon (A4) assuming that a predetermined position of the movement source icon (A4) is selected on the display screen.
