Video Call Navigation with AR Route Overlays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video call technologies do not allow users to visually share and verify navigation information, relying solely on voice explanations during route queries.
Innovation Solution
A method and system that provides augmented reality (AR)-based navigation information during video calls by transmitting current location-based video data, receiving instruction information, and generating navigation information based on location data, allowing users to visually share and update navigation guidance in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If video call service is provided using traditional audio-only navigation, then device complexity is reduced, but information transmission completeness deteriorates
Solution Approach 1:
The patent merges video call functionality with navigation information sharing by integrating the navigation information receiver and video data transmitter within the existing video call framework. This allows navigation information to be shared through the video call interface without requiring separate communication channels or additional devices, thus reducing system complexity while improving information transmission completeness.
Solution Approach 2:
The video call terminal is designed to perform multiple functions: traditional video communication and navigation information sharing. The navigation information receiver enables the terminal to receive and process navigation data, while the video data transmitter shares both video feeds and navigation information through the same communication channel, making the device universal and reducing the need for specialized equipment.
2Measurement precision
If navigation information is shared through voice explanation only, then ease of operation is maintained, but measurement precision of route verification deteriorates
Solution Approach 1:
The patent transitions navigation information from one-dimensional audio-only transmission to two-dimensional visual presentation by displaying navigation information on the video call screen. This dimensional change allows users to visually verify routes with high precision while maintaining ease of operation through the intuitive video call interface, eliminating the need for complex separate navigation operations.
3Loss of information
If AR-based navigation information is transmitted during video call, then information transmission completeness is improved, but use of energy increases
Solution Approach 1:
The patent combines AR navigation information transmission with the existing video call data stream, merging multiple information types (video feed, navigation data, AR overlays) into a single integrated transmission channel. This approach improves information completeness by sharing all elements simultaneously while optimizing energy consumption by utilizing the already-established video call connection rather than creating separate high-bandwidth channels.
4Reliability
If navigation information is updated in real-time during video call, then reliability of navigation is improved, but productivity of communication deteriorates
Solution Approach 1:
The patent implements continuous navigation information updates during the video call by maintaining an ongoing exchange between the navigation information receiver and the video data transmitter. This continuous action ensures navigation reliability through real-time updates while preserving communication productivity by integrating the updates into the natural flow of the video call without requiring pauses or separate communication phases.

AI summary
Disclosed is a computer-implemented navigation method including transmitting, to a counterpart terminal, current location-based video data that is input to a video call screen of a terminal during a video call; receiving instruction information for a navigation based on the video data from the counterpart terminal that displays the video data on a video call screen of the counterpart terminal; generating navigation information by mapping the instruction information to the video data of the terminal; and providing the navigation information based on location information of the terminal.
