Solution Overview
Problem
Existing positioning systems require excessive time and user input when transitioning from low precision to high precision positioning, leading to user dissatisfaction due to prolonged wait times.
Innovation Solution
A positioning apparatus that simultaneously performs low precision positioning and displays initial results quickly, while concurrently conducting high precision positioning in the background, allowing for immediate display of low precision information and subsequent update to high precision information without additional user wait time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If high precision positioning is executed after low precision positioning, then positioning precision is improved, but positioning time and user wait time increase excessively
Solution Approach 1:
The system performs preliminary low precision positioning to provide immediate position information to the user, while simultaneously initiating high precision positioning in the background. This preliminary action ensures that the user receives position information without excessive wait time, while the more precise measurement is already underway.
Solution Approach 2:
The patent introduces a temporal dimension by executing low precision positioning and high precision positioning simultaneously rather than sequentially. The low precision positioning provides immediate feedback while the high precision positioning runs in parallel, effectively adding a time dimension to the positioning process.
2Measurement precision
If repositioning is required for high precision, then positioning accuracy is improved, but user satisfaction decreases due to prolonged wait time
Solution Approach 1:
The system provides preliminary position information from low precision positioning immediately, satisfying the user's initial need for location data. The high precision positioning is prepared in advance and updated automatically, ensuring the user receives accurate information without having to wait through a lengthy process.
Solution Approach 2:
The system implements feedback by continuously updating the displayed position information. When high precision positioning completes, the system automatically updates the display with the more accurate position data, providing the user with improved accuracy without requiring manual re-initiation or causing prolonged wait time.
3Measurement precision
If sequential positioning (low precision then high precision) is used, then positioning accuracy is improved, but total time required for positioning increases
Solution Approach 1:
The patent merges low precision positioning and high precision positioning into a single simultaneous operation. Both positioning systems run in parallel, sharing the same time window, which combines their advantages: immediate position information from low precision positioning and high precision accuracy from the high precision positioning, without the sequential time penalty.
Solution Approach 2:
The low precision positioning is executed as a preliminary action that provides immediate results, while the high precision positioning is initiated simultaneously as a background process. This preliminary action ensures productivity is maintained while accuracy is improved through the concurrent high precision measurement.

AI summary
A positioning apparatus having short sensory time for executing the high precision positioning of the user on a map. The positioning apparatus includes: a first positioning unit for obtaining a first position information which represents the position of the positioning apparatus itself measured by carrying out a low precision positioning; a displaying unit for displaying the first position information; and a second positioning unit for obtaining the second position information which represents the position of the positioning apparatus itself measured by carrying out a high precision positioning. The high precision positioning is executed in parallel with the low precision positioning. The displaying unit updates a screen based on the second position information.
