Solution Overview

Problem

Current game control technologies using input device position and posture for movement inputs lack user-friendliness, as they require precise movements and tilting, which can be cumbersome and less intuitive.

Innovation Solution

A game control program that acquires the position and inclination of an input device, combining positional and inclination displacement amounts with weighted values to determine object movement on a screen, allowing players to move objects by both moving and tilting the device, with greater emphasis on positional displacement for intuitive control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If only positional displacement of the input device is used for control, then the control method is simple, but the control precision and responsiveness are insufficient

Engineering Contradiction:
Improvecontrol precisionVSAvoidcontrol method complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent combines positional displacement information and inclination displacement information from the input device to control the object's movement on the screen. By merging these two different types of input data, the system achieves higher control precision and responsiveness while maintaining relatively simple implementation through weighted summation of the two displacement amounts.

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If precise tilting movements are required for control, then the control precision is high, but the ease of operation decreases

Engineering Contradiction:
Improvecontrol precisionVSAvoidease of operation
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent introduces a weight coefficient that can be adjusted to change the contribution of positional displacement versus inclination displacement to the final control output. This parameter adjustment allows the system to adapt between prioritizing precision (higher inclination weight) or ease of operation (higher positional weight), providing flexibility to optimize for different operational contexts.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the input device must be moved widely for large object movement, then the control range is large, but the ease of operation decreases

Engineering Contradiction:
Improvecontrol rangeVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By combining positional displacement and inclination displacement with adjustable weights, the system achieves adaptable control range. When wide movement is needed, the inclination component can be weighted higher to achieve large displacements with minimal physical movement, while maintaining the option for precise control when needed.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of operation

If only inclination displacement is used for control, then the ease of operation improves, but the measurement precision of positional control decreases

Engineering Contradiction:
Improveease of operationVSAvoidpositional control precision
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The weight coefficient serves as a adjustable parameter that balances ease of operation against positional control precision. By modifying this parameter, the system can shift between relying more on inclination (easier operation) or more on positional displacement (higher precision), allowing optimization based on specific operational requirements.

Inventive Principle:
Principle #35Parameter changes

AI summary

A game device is provided with a position acquisition unit for acquiring the position of an input device for moving the position of a given object on a screen displayed on a display device; an inclination acquisition unit for acquiring the inclination of the input device; and a position computation unit 118 for determining the position of the object on the screen based on both a positional displacement amount of the input device and an inclination displacement amount of the input device. The position computation unit 118 may determine the position of the object based on a value obtained by adding the positional displacement amount and the inclination displacement amount after assigning a weight to each displacement amount.
