Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing six degrees of freedom (6DoF) tracking systems for virtual reality (VR) and augmented reality (AR) applications require extensive external monitoring apparatus setup and are costly when used outside of a pre-calibrated space, limiting their adoption and functionality.
Innovation Solution
A self-contained tracking core that can be mounted on a host device to monitor position and orientation in 6DoF without external apparatus, communicating with an MR device to display holographic images and interactive elements based on the host device's specifications and tracking data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external monitoring apparatus (cameras/sensors) are used for 6DoF tracking, then tracking accuracy is improved, but device complexity and setup requirements increase
Solution Approach 1:
The tracking core enables the peripheral device to track its own position and orientation autonomously using onboard sensors (accelerometers, gyroscopes, magnetometers) without requiring external monitoring apparatus. The system performs self-measurement of spatial data, eliminating the need for complex external camera systems and reducing setup complexity while maintaining tracking accuracy
Solution Approach 2:
The tracking functionality is extracted from the peripheral device and consolidated into a separate tracking core module. This allows the tracking core to be independently configured with appropriate sensors and processing capabilities, while the peripheral device remains simple. The tracking core can be attached to various peripherals without modifying their basic structure
2Adaptability or versatility
If self-contained tracking components are integrated into peripheral devices, then adaptability is improved, but system cost increases
Solution Approach 1:
The tracking core is designed as a universal module that can be attached to multiple types of peripheral devices (controllers, smartphones, tablets, wearables) through standard connection interfaces. A single tracking core design serves multiple functions across different device types, achieving adaptability without requiring custom tracking solutions for each peripheral, thereby controlling manufacturing costs
Solution Approach 2:
The tracking system is segmented into a modular tracking core that can be separately manufactured and then attached to various peripheral devices. This segmentation allows for economies of scale in producing the tracking core component, which can then be paired with different peripherals, reducing overall system cost compared to integrating tracking components into each individual peripheral device
3Reliability
If external sensors are spaced around a bounded space, then tracking reliability is improved, but ease of operation deteriorates due to calibration requirements
Solution Approach 1:
The tracking core performs self-calibration and automatic environment mapping when first deployed. The onboard sensors continuously collect spatial data and automatically establish the device's position and orientation without requiring manual calibration by the user. This maintains tracking reliability while significantly improving ease of operation

AI summary
Disclosed is a self-contained, pluggable tracking system that monitors six degree of freedom (“6DoF”) without external apparatus, e.g., visual tracking or magnetic. The tracking core can communicate with a host device and with an external computing device. The external computing device can display a virtual (“VR”) or augmented reality (“AR”) world. The VR or AR world may be supplemented by overlay displays positioned according to the shape of the host device as tracked by the tracking core.
