Представьте себя в незнакомом метро — вокруг бетонные стены, нет сигнала GPS, мобильный интернет работает с перебоями, а вам надо быстрой понять где в переходе вы находитесь.
Or how do you define:
- Which stations is your train located between?
- How much time is left before your stop?
- When should I get ready to leave?
Traditional methods like looking out the window for station names or trying to hear announcements have long been outdated. Modern technology offers an elegant solution!
How does this solution work??
The new algorithm determines your location in the underground space by analyzing the characteristic vibrations of your smartphone due to the built-in sensors.
Classification of movement
When the train enters the tunnel:
- The smartphone detects vibrations with a frequency of ~5 Hz (train movement)
- When walking, the smartphone detects a frequency of ~2 Hz
- Escalators and elevators will have their own unique frequency characteristics.
Collection of reference data
It is necessary to conduct a large-scale study and collect data from different stations, crossings and escalators.:
- lots of subway rides in different cities
- dozens of types of rolling stock
- go through all possible scenarios (stops, acceleration, turns)
Neural network training
- The algorithm is trained on thousands of trips in different subways around the world
- It accurately distinguishes train movement from other passenger activities
Key advantages
It works without internet connection
All calculations take place directly on your device.
Complete confidentiality
Your data never leaves your smartphone.
Versatility
The algorithm can be adapted to any type of subway system.
Но есть один важный недостаток такого решения — не высокая точность определения положения в большом пространстве. Например можно достаточно точно понять на какой станции вы находитесь, но уже в каком месте этой станции вы стоите или около какого вагона, с высокой точностью не получится. Для повышения точности позиционирования это решение модно совмещать с уже ставшей привычной навигацией по маячкам iBeacon.
Why is this important for shopping malls, airports, and hospitals?
The technology developed for the subway may be well suited for indoor navigation on the surface of the earth! After all, the same problems often occur in shopping malls, hospitals, and office centers.:
- There is no GPS signal/Glonass
- Poor connectivity and insufficient wi-fi coverage
- People get lost in large spaces and waste their time.
Indoors Navigation offers similar solutions for a wide range of industries and for a variety of tasks.:
Shopping malls
- Shows the way to the desired store
- Leads on promotions and discounts
- Analyzes the flow of visitors
Airports
- Escorts them to the boarding gates
- Finds baggage carousels
- Shows power points and other POI
Hospitals
- It leads to the right doctor's office
- Builds routes for hospital visitors
- Optimizes the work of staff and the search for medical equipment
How does it work in buildings?
Instead of train vibrations, we use data received over the radio channel, and as a result, navigation appears where GPS and Glonass are powerless. To do this, we use:
- Bluetooth beacons
- Accelerometer and gyroscope of a mobile device
- Digital indoor maps and shortest routes
