AR VR Control via BLE UWB Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented and virtual reality systems are costly and lack precise location-based functionality, especially in home entertainment environments, requiring users to wear headsets and move their heads to control content.
Innovation Solution
The use of Bluetooth low energy (BLE) and/or ultrawide band (UWB) communications with handheld or wearable control devices, combined with multi-axis sensor fusion and cameras, to provide precise positioning and control AR/VR content on display screens without the need for headsets, allowing multiple users to control content in different locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If headsets are used for AR/VR content control, then immersive experience is provided, but cost increases and location-based functionality precision deteriorates
Solution Approach 1:
The patent introduces handheld or wearable control devices as intermediaries between users and AR/VR content delivery systems. These control devices equipped with BLE/UWB transceivers and sensors serve as mediators that enable precise location tracking and content control without requiring expensive headset equipment. The control devices communicate with display devices and content delivery systems to achieve the desired functionality at lower cost.
Solution Approach 2:
The patent replaces the mechanical/head-mounted tracking system with a wireless communication-based positioning system using BLE and UWB technologies. Instead of relying on headsets with internal sensors and processors, the system uses control devices with transceivers that communicate wirelessly with display devices to determine user location and control content, thereby reducing cost while maintaining or improving positioning precision.
2Ease of operation
If headsets are used for content control, then immersive experience is provided, but ease of operation deteriorates due to head movement requirements
Solution Approach 1:
The control devices act as intermediaries that separate the user from the display device, allowing users to control AR/VR content from a distance without moving their heads. The control devices with transceivers and sensors track user location and transmit control signals wirelessly, providing both ease of operation and precise location-based functionality simultaneously.
3Measurement precision
If conventional display screens are used, then big screen experience is provided, but location-based content control precision deteriorates
Solution Approach 1:
The patent replaces physical proximity-based control with wireless communication-based positioning using BLE and UWB technologies. The transceivers in control devices and display devices enable precise positioning and content control independent of display screen size, allowing accurate location-based functionality even with large display screens.

AI summary
A controlling device is used to control a presentation of a one of a AR content or a VR content on a display device. A radio frequency connection between the controlling device and a signaling device located remotely from the controlling device is used to determine at least an orientation of the controlling device relative to the signaling device. The presentation of the one of the AR content or the VR content on the display device is then controlled as a function of the determined at least the orientation of the controlling device relative to the signaling device;
