Eyewear Terminal Real-Time Navigation via Visual Recognition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile terminals lack effective navigation assistance for users who are lost, especially in unfamiliar environments, as they rely on visual recognition and do not provide real-time directional guidance based on the user's current visual field.
Innovation Solution
An eyewear-type terminal equipped with a camera, sensors, and a control unit that generates and outputs road guide information by recognizing objects within the user's visual field, providing turn-by-turn directions and highlighting relevant objects to guide the user to their destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional mobile terminals provide navigation assistance, then users can receive route information, but users cannot effectively recognize directions in real-time while moving
Solution Approach 1:
The patent introduces an intermediary system consisting of a camera, object recognition module, and augmented reality display that mediates between the navigation system and the user. The camera captures real-time visual information, the recognition module processes it to identify relevant objects and directions, and the AR display presents this information overlaid on the user's field of view, enabling intuitive real-time navigation without requiring the user to look at a separate device
Solution Approach 2:
The patent transitions from traditional 2D map-based navigation to 3D spatial navigation by overlaying directional information and location markers directly onto the user's real-world visual field. This dimensional change allows users to perceive navigation cues in the same spatial context as their environment, making direction recognition more intuitive and reducing cognitive load
2Loss of information
If visual recognition is used for navigation, then route information can be displayed, but users must divert attention from their surroundings
Solution Approach 1:
The camera acts as an intermediary that captures environmental information, allowing the system to process navigation data without requiring the user to shift their gaze. The AR display then presents this information within the user's existing field of view, eliminating the need to look away at a separate device and maintaining situational awareness
Solution Approach 2:
The patent applies navigation information locally within specific regions of the user's field of view rather than requiring global attention shifts. By overlaying directional arrows, location markers, and route guidance directly onto relevant areas of the visual scene, the system delivers route information without compromising the user's ability to monitor their surroundings
3Loss of information
If traditional navigation interfaces are used, then route information can be provided, but users struggle to locate destinations in unfamiliar environments
Solution Approach 1:
The object recognition module serves as an intermediary that identifies and tracks specific environmental features, buildings, and landmarks. By continuously recognizing and locating these objects in the camera feed, the system can precisely determine the user's position relative to the destination and provide accurate real-time feedback on location and direction
Solution Approach 2:
The patent implements continuous feedback by constantly comparing the user's current position (determined through camera-based object recognition) with the intended destination. The system provides real-time feedback through AR overlays that show directional arrows, distance information, and location markers, allowing users to immediately adjust their course and maintain accurate navigation to the destination

AI summary
An eyewear-type mobile terminal includes a camera; an output unit configured to output road guide information; and a controller configured to: acquire information about a current position; cause the output unit to output the road guide information for a route from the current position to a destination; cause the camera to acquire visual information in real-time while the road guide information is output; and update the road guide information in real-time based on the acquired visual information.
