Location-Based Information Delivery for Smart Terminals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in obtaining and managing sightseeing information using smart terminals, as they need to search for and download information in advance, which can be outdated, and car navigation systems are hard to operate, especially for passengers, leading to inefficiencies in accessing real-time information.
Innovation Solution
A method where a computer communicates with a terminal to collect and deliver application contents based on the user's location, automatically organizing and deleting information when entering or exiting specific areas, using a car navigation apparatus and an information collection-and-delivery server to push relevant information to a smart terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a user searches for and downloads sightseeing information in advance using a smart terminal, then the user can obtain information beforehand, but the information may be outdated and the user spends excessive time and effort
Solution Approach 1:
The system performs preliminary actions by collecting application contents when the computer enters a first area surrounding a second area, preparing information in advance but not delivering it until the user actually arrives at the destination area, ensuring both timely delivery and information freshness
Solution Approach 2:
The system uses location feedback from the terminal to automatically trigger information collection and delivery based on actual user movement, ensuring information is delivered at the right time without requiring manual user action, thus maintaining information freshness while reducing user effort
2Reliability
If a user uses limited-area one-segment broadcasting to obtain sightseeing information, then real-time information can be obtained, but the user must be physically present in the area
Solution Approach 1:
The computer acts as an intermediary that collects application contents from services when entering a first area, stores them, and then delivers them to the terminal when entering the second area, allowing the user to receive information without being physically present in the broadcast area
Solution Approach 2:
The system copies application contents from the service to the computer's storage, creating a local copy that can be delivered to the terminal on demand, eliminating the need for the user to be in the original broadcast area while maintaining information accessibility
3Measurement precision
If a car navigation apparatus provides sightseeing information, then accurate location-based information is available, but passengers cannot operate it and the driver cannot attend to passenger needs
Solution Approach 1:
The system extracts the information provision function from the car navigation apparatus by having the computer collect and deliver application contents to the terminal, allowing passengers to access information on their own devices without the driver needing to operate anything
Solution Approach 2:
The terminal automatically receives information pushed from the computer based on location data, enabling passengers to passively receive relevant sightseeing information without any manual operation, thus making the system accessible to all passengers including those who cannot operate navigation devices
4Reliability
If information is continuously delivered to the terminal, then real-time information is available, but battery life is consumed
Solution Approach 1:
The system uses periodic location-based triggering where the computer monitors when the terminal enters the second area and only then delivers the collected application contents, avoiding continuous transmission and reducing battery consumption while maintaining real-time information availability when needed

AI summary
A method performed by a computer communicating with a terminal. The method includes when the computer enters a first area surrounding a second area together with the terminal, collecting one or more application contents corresponding to the second area from a service; when the computer enters the second area together with the terminal, delivering the collected application contents to the terminal; when the computer exits the second area together with the terminal, requesting the terminal to delete or nullify the delivered application contents; and when the computer exits the first area together with the terminal, organizing the collected application contents.
