Gyroscopic Weight Shifting for Posture Correction

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing video game device peripherals, such as controllers and headsets, cause users to develop imbalanced postures leading to potential injuries and reduced gaming performance due to lack of effective posture correction methods that are non-invasive and immersion-breaking.

Innovation Solution

A peripheral device with a processor that adjusts weight distribution based on orientation information from a gyroscope to provide haptic feedback, indicating users to correct their posture subtly and intuitively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a back brace is used to correct user posture, then posture correction is achieved, but the device becomes invasive and uncomfortable

Engineering Contradiction:

Improveposture correction effectivenessVSAvoidinvasiveness and discomfort

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces the mechanical back brace system with a peripheral device that uses haptic feedback through weight distribution adjustment. Instead of physically constraining the user's posture through a brace, the system subtly shifts weight in the peripheral device to guide the user into correct posture through tactile sensation, eliminating the need for invasive mechanical structures.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The peripheral device acts as an intermediary between the user and the posture correction function. Rather than directly applying corrective force through a back brace, the system uses the peripheral device as a mediator that provides indirect guidance through weight distribution changes, making the correction process more comfortable and less intrusive.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If screen messages are displayed to instruct user to return to neutral posture, then posture correction guidance is provided, but immersion is broken and user experience is detracted

Engineering Contradiction:

Improveposture correction guidanceVSAvoidimmersion breaking

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent replaces visual screen messages with tactile haptic feedback through weight distribution adjustment. Instead of displaying text or visual cues that break immersion, the system uses subtle changes in weight distribution that the user can feel through the peripheral device, providing posture guidance while maintaining visual immersion in the game or application.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent uses tactile 'color changes' in the form of weight distribution variations to convey posture information. Different weight distributions create distinct tactile sensations that guide the user without visual disruption, similar to how color changes convey information without breaking visual immersion.

Inventive Principle:

Principle #32Color changes

3Reliability

If force is applied to user's body to correct posture involuntarily, then posture correction is achieved, but user bodily autonomy is compromised and user feels out of control

Engineering Contradiction:

Improveposture correction effectivenessVSAvoiduser bodily autonomy

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where the peripheral device continuously monitors user posture through orientation sensors and provides real-time weight distribution adjustments as feedback. This gentle feedback guides the user toward correct posture through subtle tactile cues rather than forcing involuntary correction, maintaining user autonomy and sense of control while achieving posture correction.

Inventive Principle:

Principle #23Feedback
