How to collect data and test NAO Campus?

2 ©Pole Star 2013 - All Rights Reserved 21/07/2014

You are halfway to setting up NAO Campus Indoor Location solution.

Venue modeling done. Data collection to do.


The aim is to create a positioning database (PDB)

from the collected sensory data of the whole venue.

e.g : Wi-Fi or Bluetooth Low Energy (BLE) power levels


For positioning on Android,

existing Wi-Fi infrastructure can be used

For positioning on iOS,

our BLE beacons are required

Our BLE beacons can also be used

if your Wi-Fi network is not dense enough.

BLE-based positioning only works on Android 4.3+


You can order BLE Beacons on NAO Cloud


Once your Wi-Fi and/or BLE infrastructure is ready.

You can go collect measurements in the building.


To collect measurements,

you’ll walk everywhere in the building

twice (forth, back, forth, back)

with our setup mobile app running on your smartphone


The app displays the floor plans.

While walking, every once in a while,

place a waypoint at your current location on the floor plans.

The system will associate the sensory data collected along the way

with your locations and will generate a Positioning Database.


A: When you…

Q: So when exactly do I have to place a waypoint

at my current location on the floor plans?

stop

walking

change

direction

are at a path

Intersection


A: While still walking…

Q: And How?

2. Press the marker button

1. Drag to put the green dot

on your current position

Here, I have walked all the dark green paths

left the blue part to cover.


Our setup mobile app is called NAO Logger,

available on Google Play and Apple App Store

The one on Google Play can be used for both Wi-Fi and BLE deployment.

The one on Apple App Store only is used for BLE deployment.


1. Authenticate yourself 2. Select your venue 3. Let it download itself 0. Install then launch

NAO Logger

Then we arrive at the main screen…


Number of BLE or

Wi-Fi beacons detected

Start or stop collecting data

Downstairs maps

Level number

Synchronize data

with server

For data collection

For positioning testing

Path left to walk

Path already

walked


Now press Start


The Start button

changed to Stop

The Marker button

appeared

The green dot should be

your current location

when you press the

Marker button


Now, imagine right now your are at A

and you want to collect data

from A to B


2 markers now

1. Press Marker button to tell you are at A

2. Start walking toward B

3. While walking, drag the maps so that

the green dot glides to B

4. When you arrive at B,

press Marker a second time

and continue walking toward another point

Note:

no need to stop when pressing

Marker button

A B


The blue path is walked one way (A to B)

If you now collect data from B to A,

the blue path will be entirely covered in green

A B


Continue collecting data until

all blue paths turn green.

Then press the Stop button

to save the data

Note:

You can use Stop / restart whenever

you want to take a break.


Do not forgot to collect data on floor transitions

(stairs, escalators, elevators, etc)

A

B

1. Press Marker at A

2. Take the stairs or escalators

3. Press Downstairs button

4. Press Marker at B


Once all the walkable paths are green,

press Synchronize to send

collected data to the server.


Switch to the Demo Mode in the application,

let the system download the Positioning Database.

You are now located

by the app the blue dot shows your location
