AR Glasses Gaze-Based Wireless Device Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Augmented reality (AR) glasses have limited input interfaces due to their small size and proximity to the eyeball, making it difficult for users to wirelessly connect to external devices, especially when selecting the correct device for connection.
Innovation Solution
Incorporating a camera, communication circuit, and processor in AR glasses to acquire images of external devices, identify devices based on gaze direction, and establish wireless connections to devices running specified applications, thereby simplifying the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If the display is positioned close to the eyeball to provide a large-sized image, then the image size is improved, but the input interface capability deteriorates due to small size and proximity
Solution Approach 1:
The patent introduces an external electronic device as an intermediary that provides the input interface capabilities lacking in the AR glasses. The glasses communicate with this external device to enable functions like device selection and connection establishment, effectively transferring the input interface functionality to an external mediator.
Solution Approach 2:
The system separates functions into two parts: the AR glasses handle display and gaze tracking, while the external electronic device handles input processing and device management. This segmentation allows each component to be optimized independently - the glasses remain compact for comfortable wear while the external device provides comprehensive input capabilities.
2Weight of moving object
If the HMD device is designed to be small and lightweight for comfortable wear, then wearability is improved, but the input interface and device selection capability deteriorate
Solution Approach 1:
The external electronic device serves as a mediator that compensates for the limited input capabilities of the lightweight AR glasses. Users can select and connect to devices using the external device's interface, which then communicates the selection back to the glasses, enabling device selection without adding weight to the glasses themselves.
3Measurement precision
If manual input is required for device connection, then connection accuracy is improved, but operation complexity and time consumption increase
Solution Approach 1:
The system enables self-service connection by using the camera to automatically detect external devices and the gaze tracking system to automatically determine user intent. When the user looks at a device, the system automatically initiates connection without requiring manual input, achieving both accuracy and simplicity.
Solution Approach 2:
The patent replaces manual mechanical input (buttons, switches) with optical detection (camera-based device recognition and gaze tracking). This substitution eliminates the need for physical input operations while maintaining accurate device selection through visual identification and eye direction detection.
