Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Toy weapons that include a hilt and a blade do not effectively simulate the resistance of moving a virtual weapon, lacking the immersive experience of handling a virtual counterpart.

Innovation Solution

A system utilizing a gyroscope to simulate the resistance of moving a virtual weapon by determining the position and orientation of a virtual blade, overlaying it on a display, and controlling the gyroscope to provide resistance to the hilt's orientation changes, thereby mimicking the feel of handling a virtual weapon.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a gyroscope is integrated into the hilt to provide resistance to orientation changes, then the immersive experience of handling a virtual weapon is improved, but the device complexity increases

Engineering Contradiction:

Improveimmersive experienceVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The gyroscope, image sensor, motion and orientation sensor, and other electronic components are nested within the hilt structure. The hilt serves as a container that houses multiple subsystems, with components arranged in a compact configuration where smaller units are integrated within the overall hilt assembly, reducing external complexity while maintaining internal functionality.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The hilt is designed as a multi-functional device that simultaneously serves as a physical handle, a mounting structure for sensors and gyroscopes, a wireless communication node, and an interface for virtual weapon control. The image sensor both captures visual data for augmented reality display and provides motion tracking information, while the gyroscope contributes to both stabilization and resistance simulation, allowing one component to fulfill multiple roles.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple sensors and gyroscopes are integrated into the hilt to track position and orientation, then the accuracy of virtual blade positioning is improved, but the weight of the hilt increases

Engineering Contradiction:

Improveposition and orientation accuracyVSAvoidhilt weight

Core Design Contradiction:

Measurement precisionVSWeight of moving object

Solution Approach 1:

The sensing system is segmented into multiple independent components distributed throughout the hilt structure. Rather than using a single heavy sensor unit, the system divides functionality across multiple lighter sensors (image sensor, motion sensor, orientation sensor, gyroscope) positioned at different locations, each contributing specific measurement data that collectively achieves high positioning accuracy without concentrating excessive weight in one location.

AI summary

This disclosure relates to systems and methods for using a gyroscope to change the resistance of moving a virtual weapon to simulate a feel of moving the virtual weapon. A feel of moving a virtual weapon may be simulated by determining a position and/or an orientation of a virtual blade of the virtual weapon, determining controls for a gyroscope based on the position and/or the orientation of the virtual blade, and operating the gyroscope in accordance with the controls for the gyroscope to provide resistance to changing the orientation of the hilt, wherein the resistance to changing the orientation of the hilt simulates the feel of moving the virtual weapon.
