Solution Overview

Problem

Information processing devices using touch panels face challenges in minimizing user errors during input selection, particularly when the device is held in one hand, as the direction of finger movement deviates from standard directions, leading to incorrect input item selection.

Innovation Solution

An information processing device that includes an acquisition unit for detecting the touch point, a detection unit for determining the direction of movement, a calculation unit for calculating the angle of deviation, and a correction unit that adjusts the placement of input items based on this angle, ensuring accurate selection by rotating the input items accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the device is held in one hand for easy operation, then ease of operation is improved, but the direction of finger movement deviates from standard directions causing incorrect input item selection

Engineering Contradiction:
Improveease of operationVSAvoidinput selection accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies dynamics by making the input item placement adaptive and changeable based on detected touch movement direction. Instead of fixed standard directions, the system dynamically adjusts input item positions to match the user's actual finger movement pattern when holding the device in one hand, thereby maintaining both ease of operation and input selection accuracy

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the spatial parameters of input item placement based on the detected angle of touch movement. By calculating the deviation angle from standard directions and adjusting input item positions accordingly, the system adapts to one-handed holding conditions while preserving input accuracy

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If input items are placed in standard directions around a reference point, then device complexity is simplified, but user errors increase when the device is held in one hand

Engineering Contradiction:
Improveinput interface complexityVSAvoidinput selection accuracy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system performs preliminary detection of the touch movement direction before finalizing input item selection. By detecting the angle of movement in advance and pre-adjusting the input item placement to match this direction, the system prevents user errors while maintaining a simple interface structure

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by detecting the actual touch movement direction and using this information to adjust input item placement. This closed-loop approach ensures that the input interface adapts to one-handed holding conditions, reducing user errors without significantly increasing interface complexity

Inventive Principle:
Principle #23Feedback
