Electric Device Real-Time Location Information Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile phones lack an efficient method to display and update information on nearby geographic locations and facilities in real-time, especially when the user moves, as they rely on static map data and do not effectively integrate augmented reality with navigation functions.
Innovation Solution
An electric device equipped with a location detector, display, and processor that acquires and displays information on nearby geographic locations and facilities using a database, allowing for real-time updates and switching between map and augmented reality views based on user interaction and device orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the mobile phone displays static map data, then the device complexity is low, but the information update capability in real-time is poor
Solution Approach 1:
The system pre-acquires map data and facility information from a database before the user needs it. When the user moves to a new location, the system has already prepared the relevant information, enabling real-time updates without complex processing during actual navigation.
Solution Approach 2:
The patent implements dynamic switching between map view and augmented reality view based on user interaction and device orientation. The display content automatically updates as the user moves, transitioning from static map data to dynamic augmented reality overlays that show facility information in real-time.
2Loss of information
If the mobile phone uses augmented reality view, then the information display capability is improved, but the power consumption increases
Solution Approach 1:
The system dynamically switches between map view and augmented reality view based on user needs and device orientation. This allows the high-power augmented reality mode to be used only when necessary, while the lower-power map view handles general navigation, thus balancing information display capability with power consumption.
Solution Approach 2:
The system updates augmented reality information periodically based on device orientation changes and user movement, rather than continuously rendering. This periodic update approach maintains effective information display while significantly reducing the power consumption associated with constant augmented reality rendering.
3Measurement precision
If the mobile phone updates information continuously, then the information accuracy is improved, but the productivity is reduced
Solution Approach 1:
The system pre-acquires and caches map data and facility information from databases before navigation begins. This preliminary data preparation ensures accurate information is readily available when needed, eliminating the need for continuous real-time data acquisition during navigation and thus maintaining productivity.
Solution Approach 2:
The system performs periodic updates of location and facility information based on triggers such as device orientation changes or reaching new geographic areas. This periodic update mechanism maintains high information accuracy by refreshing data at appropriate intervals rather than continuously, preserving navigation productivity.
Data Source
AI summary
An electric device includes a location detector, a display, and at least one processor. The location detector detects a current position. The display displays an object for performing an application in an area of a screen. At least one processor acquires information of one or more geographic locations near the current position from a database, and causes the display to display the information in the area.
