Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing display control systems for portable terminal devices change the arrangement of application icons frequently when priority levels are updated, causing user annoyance.

Innovation Solution

A display control device that computes priority levels for applications based on usage frequency and other factors, rearranging high-priority icons in a designated region while fixing the positions of other icons, thereby minimizing changes in icon arrangement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If icon arrangement is determined based on priority levels, then applications can be displayed according to usage frequency, but the arrangement changes frequently causing user annoyance

Engineering Contradiction:

Improveadaptability of icon arrangement to usage patternsVSAvoidstability of icon arrangement

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The display area is divided into a prescribed region and other regions. Icons are segmented into those that should be fixed (preserved icons) and those that can be rearranged (replaceable icons). This segmentation allows partial adaptation while maintaining stability for important elements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system preliminarily determines which icons should be fixed based on usage history before performing rearrangement. By pre-identifying preserved icons, the system avoids frequent changes to stable elements while still adapting the replaceable portion to current usage patterns.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If all icons are subject to rearrangement, then the display can fully adapt to usage patterns, but essential icons may be moved or hidden

Engineering Contradiction:

Improveresponsiveness to usage frequency changesVSAvoidvisibility of essential applications

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Essential icons are extracted from the pool of rearrangeable icons and placed in the prescribed region where they are fixed. This extraction ensures that critical applications remain visible and accessible regardless of usage pattern changes, while still allowing the system to adapt to usage patterns for non-essential applications.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A display control device comprising a display control section configured to arrange, on a display, icons for starting each of a plurality of applications, an acquisition section configured to acquire a number of times of use for each of the applications; and a computation section configured to compute a priority level for each of the applications based on a condition including the number of times of use as acquired by the acquisition section, the display control section being configured to effect a rearrangement, in a prescribed region of the display section, each icon having a high ranking for the priority level computed by the computation section, and, during the rearrangement, being configured to fix a display position of icons remaining in the prescribed region.
