Dynamic Region Determination for Mobile Terminal Data Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information providing systems fail to deliver data to terminals based on the terminal's state, such as movement speed and direction, leading to inefficient data retrieval and display.
Innovation Solution
An information providing system comprising a terminal and a server, where the server records retrieval regions based on terminal states, calculates movement speed, and adjusts the retrieval region dynamically to extract and display relevant data, using shapes like circles and ellipses to define the data retrieval area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data retrieval is performed based on a fixed provision distance from terminal position, then data can be provided in a simple manner, but the data cannot be extracted on the basis of the state of the terminal
Solution Approach 1:
The patent applies dynamics by making the retrieval region dynamic instead of fixed. The retrieval region is determined based on the terminal's state (movement state, orientation, speed) and updates accordingly. This allows the system to adapt data extraction to the terminal's current state while maintaining a relatively simple overall system architecture, resolving the contradiction between adaptability and complexity.
2Quantity of substance
If the retrieval region is enlarged to provide more comprehensive data, then more information becomes available, but the processing load increases
Solution Approach 1:
The patent applies local quality by making different regions have different retrieval characteristics. The retrieval region is divided into a first region (larger area, lower priority) and a second region (smaller area, higher priority). Data in the second region is retrieved with higher priority and processed more efficiently, while data in the first region is retrieved with lower priority. This allows comprehensive data coverage while optimizing processing efficiency by prioritizing relevant data.
3Ease of operation
If data retrieval is performed without considering terminal movement state, then the system operation is simple, but the data provision is not optimized for the user's actual needs
Solution Approach 1:
The patent applies self-service by enabling the system to automatically determine the retrieval region based on the terminal's state without requiring manual user input. The terminal's movement state, orientation, and speed are automatically detected and used to define the retrieval region. This maintains ease of operation while ensuring that the provided information is highly relevant to the user's actual needs and context.
Data Source
AI summary
An information providing system includes a terminal and a server. The information providing system includes: an information database configured to record registration data in relation to position data; a position data acquiring section configured to acquire a position data of the terminal; a state acquiring section configured to acquire a state data indicative of a state of the terminal; and a region determining section configured to determine a specified retrieval region of the registration data based on the state data. An information extracting section is configured to extract the registration data in the specified retrieval region from the information database as browser data, and a display section is configured to display the browser data.
