Solution Overview

Problem

Existing mobile game control methods, such as touch-based controls, often lead to misoperations due to direction errors in multitouch interfaces, particularly in racing games where precise gestures are required for actions like drifting and turning.

Innovation Solution

A method and apparatus that divide a virtual interface into left and right virtual sub-interfaces, detecting specific gestures and height differences of finger landing points to control virtual objects, allowing for accurate movement and action execution with reduced probability of misoperation by utilizing slide and press gestures in conjunction with a central axis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If touch-based control with multitouch interface is used, then control speed is improved, but direction accuracy deteriorates due to misoperations

Engineering Contradiction:
Improvecontrol speedVSAvoiddirection accuracy
Core Design Contradiction:
SpeedVSMeasurement precision

Solution Approach 1:

The virtual interface is divided into left and right virtual sub-interfaces, each handling gestures from corresponding hands. This segmentation prevents cross-hand interference and directional confusion, resolving the accuracy issue while maintaining speed through parallel processing of gestures

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A central axis is introduced as an intermediary reference line to determine gesture directions. The central axis serves as a mediator between the two hands, providing a clear reference for calculating directional angles and preventing misoperations in multitouch scenarios

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If gesture recognition without height difference detection is used, then device complexity is reduced, but operation reliability deteriorates

Engineering Contradiction:
Improvegesture recognition complexityVSAvoidoperation reliability
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The gesture recognition system transitions from two-dimensional touch detection to three-dimensional spatial analysis by incorporating height difference detection. This additional dimension provides extra information about gesture intent, improving reliability without significantly increasing complexity through efficient use of existing touchscreen capabilities

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
