Beacon-Based Restaurant Positioning for Indoor-Outdoor Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beacon technologies are limited in their ability to provide personalized and efficient restaurant services based on user location, particularly in determining indoor and outdoor positions and managing group interactions within restaurants.
Innovation Solution
An apparatus and method utilizing multiple beacons installed inside and outside a restaurant to determine user location through trilateration, providing tailored content based on location, and calculating user preferences by analyzing movement and thinking times to enhance service provision.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beacons are used to determine user location, then location-based service delivery is enabled, but the system cannot accurately distinguish between indoor and outdoor positions
Solution Approach 1:
The system segments the beacon network into two distinct groups: outdoor beacons and indoor beacons. Each group operates independently with its own signal characteristics, allowing the terminal to distinguish between indoor and outdoor locations by detecting which beacon group is active. This segmentation resolves the contradiction by enabling both accurate location determination and indoor-outdoor distinction simultaneously.
2Measurement precision
If beacon signals are transmitted continuously, then location detection accuracy is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous transmission, beacons transmit signals periodically at predetermined intervals. This periodic action maintains location detection capability while significantly reducing energy consumption compared to continuous transmission. The system achieves accurate location determination through regular signal pulses rather than constant transmission.
3Measurement precision
If multiple beacons are deployed for accurate trilateration, then location precision is improved, but device complexity increases
Solution Approach 1:
The beacon system is designed with universal functionality where each beacon can serve multiple purposes: location determination, indoor-outdoor distinction, and group management. By making beacons multi-functional, the system achieves accurate location precision through trilateration without proportionally increasing overall system complexity, as the same beacon infrastructure supports multiple functions simultaneously.
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
Accurately determines user location for targeted content delivery, facilitates group management, and recommends preferred restaurants based on user preferences, enhancing the overall dining experience.
Implementation Method 1
extract a first location of the user terminal based on the beacon identification signals, when the representative beacon identification signals are all related to the same restaurant, extract an inside point of the restaurant as the first location
Implementation Method 2
sort the beacon identification signals in descending order of values of received signal strength indicator (RSSI) and extract the first location using trilateration based on three representative beacon identification signals having the highest values of the RSSI

AI summary
An apparatus and method for providing a restaurant service based on user location using beacons are disclosed. According to an embodiment, an electronic device may include a memory and a processor connected to the memory. The processor may be configured to receive, from a user terminal, a plurality of beacon identification signals transmitted from a plurality of beacons, extract a first location of the user terminal based, transmit, when the first location is an outside point of the restaurant, first content corresponding to event information, menu information, empty seat information, and waiting time information related to the restaurant, and transmit, when the first location is an inside point of the restaurant, second content corresponding to representative visitor list information about members of a group, visit confirmation request information related to the restaurant, and group member count request information about the number of the members, to the user terminal.
