Gaze-Aware Wearable Notifications Across Field-of-View Zones
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to effectively provide notification information based on a user's gaze direction, particularly in wearable devices like AR and VR glasses, leading to inefficiencies in displaying relevant visual objects and notifications.
Innovation Solution
The wearable device and vehicle systems utilize sensors and communication circuits to identify a user's gaze direction and context, enabling the display of visual objects superimposed on or outside the field of view, and provide notifications based on the identified objects and contexts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If visual objects are displayed superimposed on objects within the user's field of view, then information delivery is improved, but device complexity increases due to gaze tracking and context identification requirements
Solution Approach 1:
The field of view is segmented into multiple zones (first area corresponding to gaze direction, second area excluding the first area, third area outside FoV) with different notification strategies for each zone, enabling targeted information delivery without overwhelming the entire system
Solution Approach 2:
The processor acts as an intermediary that receives raw sensor data and communication data, identifies context and object positions, determines appropriate notification methods, and controls the display accordingly, simplifying the overall system architecture
2Ease of operation
If multiple notification methods are implemented for different areas, then user interaction is improved, but ease of operation deteriorates due to increased system complexity
Solution Approach 1:
Different visual notification strategies are applied to different spatial zones within the field of view: superimposed display in the first area (gaze direction), blinking display in the second area (peripheral FoV), and represented display in the third area (outside FoV), optimizing user interaction for each location
Solution Approach 2:
The notification method dynamically changes based on the object's position relative to the user's gaze and field of view, automatically selecting the most appropriate display strategy without requiring manual user configuration
3Productivity
If gaze-based notification is implemented, then productivity is improved through timely notifications, but measurement precision requirements increase for gaze detection
Solution Approach 1:
The system implements multiple levels of gaze-based notification (superimposed, blinking, represented) that provide progressively more information as needed, ensuring timely notifications without requiring extremely precise gaze measurement for every scenario

AI summary
A wearable device comprises a display, a sensor, a communication circuit, memory comprising instructions, and at least one processor. The instructions, when executed by the at least one processor, cause the wearable device to identify a context representing a situation of a user and a position of an object associated with the context based on information obtained through the sensor and the communication circuit, display a first visual object superimposed on a periphery of the object based on verifying that the object is positioned within a first area in a field of view (FoV) area of the wearable device, display by blinking the first visual object based on verifying that the object is positioned within a second area in the FoV area, and display a second visual object representing the object in the FoV area based on verifying that the object is positioned outside of the FoV area.
