AR Glasses Positioning IoT Devices Indoor Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current home automation systems lack precise positioning of IoT devices, making it difficult to control and differentiate multiple devices of the same type within a room, as they only provide room categorization without exact location information.
Innovation Solution
The method uses AR glasses to determine the position of IoT devices by acquiring an indoor map, determining the AR-position and viewing direction of the glasses, and tracking information to calculate the IoT-position, allowing for precise identification and control of devices without manual input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If room categorization is used for IoT device positioning, then system complexity is reduced, but positioning precision deteriorates
Solution Approach 1:
The patent transitions from 2D room-level categorization to 3D spatial positioning by integrating AR glasses' six-degree-of-freedom tracking data with indoor maps. This dimensional expansion enables precise localization of IoT devices within rooms using spatial coordinates (x, y, z) and orientation information, resolving the contradiction between simplicity and precision.
Solution Approach 2:
The patent introduces AR glasses as an intermediary device that bridges the gap between simple room categorization and complex precise positioning. The AR glasses capture spatial information and transmit it to the server, which then provides accurate IoT device positions without requiring complex positioning infrastructure throughout the home.
2Measurement precision
If manual position indication is required for IoT devices, then positioning precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system enables self-service positioning where AR glasses automatically capture spatial information about IoT devices and transmit it to the server. Users simply need to view devices through the AR glasses, and the system automatically determines their positions based on tracking data and indoor map integration, eliminating manual position indication requirements.
Solution Approach 2:
The patent performs preliminary actions by pre-integrating indoor maps and pre-establishing tracking relationships between AR glasses and IoT devices. When a user points the AR glasses at a device, the positioning information is already available in the system, enabling immediate precise identification without requiring users to manually input positions at the moment of operation.
3Adaptability or versatility
If multiple IoT devices are controlled through home automation applications, then device functionality is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces manual navigation through home automation application interfaces with AR-based visual pointing. Instead of mechanically searching through application menus and device lists, users simply point the AR glasses at the physical device, and the system automatically identifies and controls the corresponding IoT device, significantly improving ease of operation while maintaining full device functionality.
