London’s Gatwick Airport now has 2,000 beacons for indoor navigation

Complicated indoor environments for example, air-ports and departmental stores is often a problem to find your way around. And although Google is seeking smartphones with 3D sensors as one probable fix for places GPS won’t correctly reach, another approach is to kit out an interior with loads of Bluetooth beacons – giving smart phone users located-locked pings to fix onto to know where they’re.

The UK’s second busiest air-port, Gatwick airport, has chosen the 2nd approach to power an indoor navigation system it’s launching as a part of a larger, multi-year transformation program.

It’s finally completed kitting out its two terminals with around 2,000 battery-powered beacons to make sure that digital map users will get a more exact blue dot as they go around. The beacon system will likewise be employed to power an augmented reality wayfinding tool – making sure that mobile users will have the ability to be guided to precise locations inside the terminals with on-screen arrows. The beacon system is planned as backing up positioning with +/-3m precision.

Gatwick is aiming to integrate indoor positioning into some of its mobile apps, and says it’s in discussions with airlines to utilize it for their own mobile apps and services – giving instance of them having the capability to send push notifications to advise travellers if they’re running late, or even make a decision on if they should wait or offload luggage so a plane can take off punctually.

Shops and other third parties will likewise be able to use the system for proximity detection of potential purchasers and push advertising and marketing messages – at least to those who have opted in to receive them.

Gatwick says it will not be collecting any sensitive information with the beacons but says “generic information on ‘people densities’ in different beacon zones” will be employed to help improve airport operations – just like queue measurement, streamlining passenger flows and reducing traffic jam.

The airport has worked with UK start-up Pointr on the system. And also developing software and managing the system on an ongoing basis, Pointr provides an SDK with support for 3D AR wayfinding to enable third parties to tap into the functionality.

MCS: 68. Working with Android Beacons

Beacons provide Android apps the opportunity to detect when a mobile user is in proximity and provide them additional services and messages. In this video for anyone just starting out with Android, we look at building a vanilla Android app to support Beacons (using the 3rd party Android Beacon Library). If you are a seasoned Android developer we recommend you look at the next video which covers what features Oracle Mobile Cloud Service can provide you to make your job easier when working with Beacons.

UK’s Gatwick Airport presently has 2,000 beacons for in-house navigation

Intricate in-house environments just like air-ports and departmental stores can be quite a bad dream to find your way around. And although Google is hunting cell phones with 3D detectors as one possible fix for places GPS won’t precisely reach, another approach is to kit out an interior with a whole lot of Bluetooth beacons – giving smart phone users located-locked pings to fix onto to learn exactly where they’re.

The UK’s second busiest air-port, Gatwick, has opted for the latter approach to power an indoor navigation system it’s launching as part of a wider, multi-year transformation program.

It’s presently finished kitting out its two terminals with about 2 Thousand battery-powered beacons to make sure digital map users will get a more exact blue dot as they walk around. The beacon system will also be used to power an augmented reality wayfinding tool – making sure that mobile users will have the ability to be guided to specific locations in the terminals through on-screen arrows. The beacon system is planned as supporting positioning with +/-3m precision.

Gatwick is about to integrate indoor positioning into some of its apps, and says it’s in discussions with airlines to utilize it for their own apps and services – giving example of them having the ability to send push notifications to warn travellers if they’re running late, or even settle on if they should wait or offload luggage so a plane can take off promptly.

Retail stores and other third parties will also be able to utilize the system for proximity detection of potential purchasers and delivery promoting messages – as a minimum to those who have opted in to receive them.

Gatwick says it won’t be gathering any personal information through the beacons but says “generic information on ‘people densities’ in different beacon zones” will be employed to help to improve airport operations – like queue measurement, streamlining passenger flows and reducing over-crowding.

The airport has worked with UK new venture Pointr on the system. In addition to developing software and managing the system on an ongoing basis, Pointr offers an SDK with support for 3D AR wayfinding to allow third parties to take advantage of the functionality.

Barista: Smart Coffee Machine

If you measure out your life with coffee spoons, here’s a chance to make this process easier presented by SoftServe R&D. More about SoftServe at: https://www.softserveinc.com/en-us/?utm_source=youtube-25apr16&utm_medium=website&utm_campaign=social

Our R&D team carried out a project to enable remote control of the coffee machine from wearable devices and provide appropriate coffee choices based on heart rate monitoring.

Having wide experience in working with embedded devices, BLE and biosignals measurement and processing, we decided to use these high-level skills and build a smart recommender to optimize and fully automate what we all need in life – a coffee preparation process. Our coffee machine remote control uses wearable devices to provide recommendations concerning which coffee to drink based on heart rate monitoring. Here are five main techs of the demo:

– Uses biosensors to read heart rate.
– Constantly measures heart rate on Apple Watch – optimized battery consumption
– Allows M2M communication – Apple Watch/iPhone – coffee machine
Detects and identifies users via iBeacon.
Uses ultrasonic proximity sensors to detect cup and brew coffee.
Read on for more details about our recommendation engine.

Apple Watch
Even though the rules are quite simple and can be run on any wearable and embedded gadgets (such as a fitness bracelet, smart watch, etc.), to ensure usability, a chosen wearable device requires an inbuilt measuring unit (for HR), an interactive display, and wireless communication.

Be it too mainstream or not, Apple Watch seems to be a perfect match. A short test-drive showed the Apple Watch has no problems with continuous heart rate measurement, and even provides more battery life (approximately 10 hours).

Hardware Design and Reverse Engineering
To make the flow fully automated we needed a coffee machine… with Wi-Fi access. Necessity is the mother of invention, so if you don’t already have this in your office, pimp the existing one.

After a brain storming session, we came up with two options:

1. Update internal modules of the coffee machine
2. Build a robot that will press buttons automatically

We have chosen the second option since it only requires combining Arduino MCU with relays. In fact, this approach is based on a machine-to-machine communication concept (in our case via an electromechanical interface).
At first, we considered a Bluetooth interface as a communication means with Apple Watch; but the idea to brew coffee out of office was so tempting that we ended up with Wi-Fi.

The cheapest Wi-Fi module we could find is the ESP8266 by Esspessif ($7 without shipping). Having examined the module from A to Z, we discovered that apart from the mentioned Wi-Fi modem it also has a complete MCU system with GPIO pins, I2C and SPI buses support. As if that were not enough, ESP8266 can be programmed with Arduino IDE. To program the microcontroller directly via USB, we purchased an ESP8266 base NodeMCU board.
With the board in place, we conducted a feasibility study to get a PoC of the working system. The next step was creating several programs that use a relay module to push buttons, write text messages on the LCD display and measure distance to the coffee cup using an ultrasonic sensor, as well as a server and client that communicate with the Apple Watch (via iPhone).

BLE and Beacons
The most challenging task was to assemble and integrate all the separate items into a coffee machine. Not only does it require additional hardware and mechanical design, but also we had to solve a user identification issue: Wi-Fi protocol itself does not allow detecting of who is currently near the machine (in simple terms, if a couple of people order different types of coffee, the machine has no clue who arrives first and what coffee to brew). Having collected different types of beacons in the run of our previous research projects, we decided to affix one to each user’s iPhone. As a matter of fact, it lets the coffee machine identify the user’s location when they are within a few meters.

However, such a solution is rather expensive and not user-friendly. So if the coffee machine doesn’t come to you, you will come to the coffee machine. A far more efficient solution is to attach a beacon to the coffee machine, which each user’s iPhone can detect.
