Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor positioning and navigation systems face challenges in providing seamless and accurate pedestrian routing within enclosed or partly enclosed facilities, as satellite-based navigation is unreliable, and existing solutions do not adequately account for user credentials and access restrictions.
Innovation Solution
A credential-based pedestrian routing system that uses a mobile device to localize users within indoor facilities, correlating fingerprint measurements and wireless communication signal signatures with sensor readings to determine customized navigation routes based on user credentials, which are stored in a fingerprint database and updated in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If satellite-based navigation systems are used for indoor positioning, then global coverage and simplicity are achieved, but positioning accuracy and reliability deteriorate due to signal unavailability in enclosed facilities
Solution Approach 1:
The patent introduces wireless communication signals (Wi-Fi, Bluetooth, cellular) as intermediary positioning aids that can penetrate and operate within enclosed facilities where satellite signals fail. These intermediary signals serve as mediators between the positioning system and the indoor environment, enabling continuous positioning across both outdoor and indoor domains.
Solution Approach 2:
The system employs a universal positioning architecture that integrates multiple positioning methodologies (satellite-based and wireless communication-based) into a single platform. This multi-functional system can automatically select or switch between positioning sources depending on the environment, ensuring reliable positioning whether outdoors or indoors.
2Productivity
If traditional routing systems are used without credential verification, then routing speed and simplicity are improved, but security and access control deteriorate as restricted areas cannot be protected
Solution Approach 1:
The system performs preliminary credential verification and access right determination before generating routing instructions. By checking user credentials and access permissions in advance, the system ensures that only authorized routes are provided, preventing unauthorized access while maintaining routing efficiency through pre-validation rather than continuous checks during navigation.
3Measurement precision
If credential-based routing with real-time updates is implemented, then routing accuracy and security are improved, but system complexity and computational requirements worsen
Solution Approach 1:
The system implements self-service mechanisms where mobile devices autonomously perform fingerprint measurements, wireless signal assessments, and credential verification without requiring complex centralized processing. The device independently determines its position and receives routing updates based on its own sensor data, reducing server-side computational burden while maintaining high routing accuracy through real-time local measurements.

AI summary
A method and a system of providing, for display at a mobile computing device, a pedestrian route associated with an indoor facility. The method comprises localizing the mobile computing device at a first position of the indoor facility, determining a credential associated with the mobile computing device, and communicating, for display at the mobile computing device, the pedestrian route from the first position to at least a second position of the indoor facility, the pedestrian route determined at least partly based on the credential.
