AR Virtual Object Interaction via In-Air Gesture Control
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
2Measurement precision
If AR/VR systems require expensive specialized equipment, then interaction precision is improved, but ease of operation and accessibility deteriorate
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.
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.
3Device complexity
If traditional input devices like keyboard and mouse are used, then device complexity is reduced, but interaction precision and immersion deteriorate
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.
Data Source
AI summary
The technology disclosed relates to a method of interacting with a virtual object. In particular, it relates to referencing a virtual object in an augmented reality space, identifying a physical location of a device in at least one image of the augmented reality space, generating for display a control coincident with a surface of the device, sensing interactions between at least one control object and the control coincident with the surface of the device, and generating data signaling manipulations of the control coincident with the surface of the device.
