Indoor Positioning via BLE Beacons and Signal Strength Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices struggle to accurately determine the proximity of mobile devices indoors due to weak GPS signal reception, leading to inadequate content delivery tailored to individual users and their locations.
Innovation Solution
A system using Bluetooth beacons installed near display devices to determine the proximity of mobile devices through signal strength analysis, combined with sensor data from the mobile device, allowing for personalized content delivery based on device type, distance, and movement parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If GPS based position tracing is used, then outdoor positioning is easily performed, but indoor positioning capability deteriorates due to weak GPS signal reception
Solution Approach 1:
The patent introduces Bluetooth Low Energy (BLE) beacons as intermediary devices to enable indoor positioning. These beacons are deployed throughout the indoor environment and serve as mediators between the mobile device and the positioning system, allowing accurate position determination without relying on GPS signals that cannot penetrate buildings effectively.
Solution Approach 2:
The patent replaces the GPS satellite-based electromagnetic positioning system with a local BLE wireless communication-based positioning system for indoor environments. This substitution enables positioning functionality to work effectively indoors by using nearby beacons instead of distant satellite signals.
2Ease of manufacture
If the same contents are provided after determining proximity of mobile device, then implementation is simple, but user needs are not fulfilled sufficiently
Solution Approach 1:
The patent implements dynamic content delivery that adapts to the user's position, movement direction, and speed. The system continuously monitors these parameters and adjusts the displayed content accordingly, transitioning from static same-content delivery to dynamic personalized content based on real-time user context.
Solution Approach 2:
The patent applies different content strategies to different spatial zones and user contexts. By analyzing the user's position relative to the display device and their movement characteristics, the system delivers locally optimized content that matches the user's immediate needs and context, rather than providing uniform content to all users.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables accurate indoor positioning of mobile devices and tailored content delivery at a minimal cost, enhancing user experience by providing relevant information based on user preferences and location.
Implementation Method 1

Implementation Method 2
Position information of the mobile device is determined using relative signal strength between at least two short distance communication modules
Data Source
AI summary
A display device and a mobile device are disclosed. The display device comprises a memory; a display module; a communication module performing communication with at least one server; and a controller controlling the memory, the display module and the communication module. Particularly, the controller changes a content output through the display module in accordance with position information of the mobile device, which is received from the server.
