Server-Mediated Location Detection for Indoor Virtual Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems fail to create a virtual communication space at a specific geographical location without prior user relationships, and they face challenges with GPS accuracy and battery consumption, as well as security issues with direct connections to public-use systems.
Innovation Solution
A method using a server-hosted virtual space that employs GPS, WIFI, or Bluetooth to determine user location, allowing interaction with public-use systems without direct connection, providing personalized information and secure communication within a defined area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If GPS coordinates are used to define virtual rooms, then location-based virtual spaces can be created, but coverage problems occur in interior of buildings and covered places
Solution Approach 1:
The patent combines multiple location determination methods (GPS, WIFI, Bluetooth) into a unified location determination module that can select and switch between different methods based on the current environment, ensuring reliable location detection both outdoors and indoors
Solution Approach 2:
The patent introduces WIFI and Bluetooth signals as intermediary location determination methods that can function when GPS is unavailable, particularly in indoor environments where satellite signals cannot penetrate
2Measurement precision
If GPS signal accuracy is improved, then location precision increases, but battery consumption increases proportionally
Solution Approach 1:
The patent implements a dynamic location determination strategy where the system automatically selects the appropriate location method (GPS, WIFI, or Bluetooth) based on the current environment and requirements, adjusting the precision and energy consumption dynamically rather than using a fixed high-precision method continuously
Solution Approach 2:
The patent changes the operating parameters of location determination by switching between different methods with different power consumption characteristics, using high-precision GPS only when necessary and lower-power methods for routine location tracking
3Ease of operation
If direct connection is established between portable device and public-use system, then interaction is enabled, but security risks increase
Solution Approach 1:
The patent introduces a server as an intermediary between the portable device and public-use systems. The server receives location information from the portable device, identifies the corresponding public-use system, and facilitates interaction without requiring a direct connection, thereby reducing security risks
Solution Approach 2:
The patent extracts the connection establishment function from the portable device and relocates it to the server, which then manages the interaction with public-use systems. This separation allows the portable device to interact with systems indirectly through the server, reducing security exposure

AI summary
The invention relates to a method for communication within a pre-determined location, which establishes a relationship between a physical space or premises defined by its geographical position and a virtual space created in a server and which replicates the information contained in said physical space. The method is configured such that a user in possession of a mobile device with an interface application for accessing the server must first enter (101) the server through the application. Subsequently, the position of the user is detected (102) and a query is sent (103) to the server, such that: if there are multiple rooms, one is listed (104) and selected (105) by the user; and if there is only one room, the data associated with said room are consulted (106) directly in the server, the data are displayed (107) to the user, the user data are consulted (108) in the server and the user data are displayed (109) to the client.
