Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing controllers with analog sticks face challenges in setting appropriate sensitivity and dead zone values that vary among different applications and users, necessitating a mechanism for user-adjustable settings.

Innovation Solution

An information processing device and controller system that allows users to adjust sensitivity and dead zone settings through a common scale interface, enabling simultaneous adjustment of both parameters via a setting screen image displayed on a connected display device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If sensitivity and dead zone are adjusted separately through different interfaces, then each parameter can be set independently, but the adjustment process becomes complex and time-consuming

Engineering Contradiction:

Improveadjustment processVSAvoidsetting time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent combines sensitivity adjustment and dead zone adjustment into a single unified setting screen interface. Users can adjust both parameters simultaneously on one screen rather than navigating through multiple separate interfaces, directly resolving the contradiction by simplifying the adjustment process and reducing setting time.

Inventive Principle:

Principle #5Merging (Combining)

2Loss of information

If sensitivity and dead zone are adjusted on different scales, then each parameter has its own reference system, but users cannot intuitively understand the relationship between the two parameters

Engineering Contradiction:

Improveparameter relationship understandingVSAvoidintuitiveness

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent projects both sensitivity and dead zone parameters onto a common visual scale dimension. The setting screen displays a unified scale where users can see the positions of both parameters simultaneously, enabling intuitive understanding of their relationship while maintaining ease of operation through visual comparison.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

3Manufacturing precision

If separate setting interfaces are used for sensitivity and dead zone, then each parameter can be optimized independently, but the overall setting efficiency decreases

Engineering Contradiction:

Improveparameter setting precisionVSAvoidsetting efficiency

Core Design Contradiction:

Manufacturing precisionVSProductivity

Solution Approach 1:

The patent creates a universal setting screen that handles both sensitivity and dead zone adjustments with a single interface. This multi-functional interface allows users to optimize both parameters independently while maintaining high setting efficiency, as the unified design eliminates the need to switch between separate interfaces while preserving individual parameter control.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An information processing device includes an operation information acquisition section, a setting screen image generation section, and a display controlling section. The operation information acquisition section acquires operation information from a controller. The setting screen image generation section generates a setting screen image for the controller. The display controlling section causes a display device to display the setting screen image for the controller. The setting screen image for the controller includes an image that indicates both a sensitivity and a dead zone of an analog stick provided on the controller in a common scale.
