Solution Overview

Problem

Current Augmented Reality (AR) and Virtual Reality (VR) systems are limited by requiring expensive equipment and complex setups, restricting user interaction to keyboard and mouse or simple hand gestures, which hinders immersive experiences and practical application for general consumers.

Innovation Solution

The system enables users to interact with virtual objects in AR/VR environments using free-form in-air gestures, leveraging motion-capture technology to track hand motions in 3D space, allowing for sub-millimeter precision without the need for specialized hardware, using smartphones or other portable devices to create virtual controls and interfaces.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional AR/VR systems use specialized hardware and complex setups, then measurement precision and interaction control are improved, but device complexity and cost increase

Engineering Contradiction:
Improveinteraction precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent uses a camera to capture images of the real-world environment and creates a virtual copy of the physical space. Virtual objects are superimposed onto this captured image, allowing users to interact with virtual elements in the context of the real environment. This copying approach eliminates the need for complex specialized AR/VR hardware while maintaining interaction precision through image-based spatial mapping.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces traditional mechanical input devices (keyboard, mouse, specialized controllers) with image-based gesture recognition. The system captures images, detects hand gestures within those images, and translates them into control commands. This substitution eliminates complex mechanical systems while achieving precise interaction through computer vision and image processing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If AR/VR systems require expensive specialized equipment, then interaction precision is improved, but ease of operation and accessibility deteriorate

Engineering Contradiction:
Improvegesture detection precisionVSAvoiduser accessibility
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The patent enables a single device (smartphone or tablet with camera) to perform multiple functions: capturing the real-world environment, detecting hand gestures, rendering virtual objects, and processing interaction commands. This universal approach allows standard consumer devices to replace specialized AR/VR equipment, improving accessibility while maintaining precision through multi-functional image processing capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system uses the device's own camera and processing capabilities to perform all AR/VR functions without requiring external specialized hardware. The smartphone or tablet captures its own environment, processes its own gesture inputs, and renders virtual objects independently, making the technology self-sufficient and widely accessible to consumers with standard devices.

Inventive Principle:
Principle #25Self-service

3Device complexity

If traditional input devices like keyboard and mouse are used, then device complexity is reduced, but interaction precision and immersion deteriorate

Engineering Contradiction:
Improveinput device simplicityVSAvoidcontrol precision
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent transitions from two-dimensional keyboard/mouse input to three-dimensional gesture recognition within captured images. Users can perform natural hand movements in the spatial context of the displayed image, allowing for more precise and intuitive control. The system detects gestures in the third dimension (depth within the image plane) and translates them into corresponding virtual object manipulations, enhancing both precision and immersion while keeping the device itself simple.

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