Quick Start Guide

This document is for people who want to provide blind navigation support. This document describes how to build map for indoor navigation-able field with iPhone and iBeacon.

Navigation methods

NavCog Version 2 supports the following two navigation methods. When you select a map, navigation method will be automatically selected based on map data.

  • 1D
    • NavCog handles edge as one-dimensional line. only beacon data is used for localization.
    • NavCog Version 1 only supports 1D method.
  • 1D PDR (Pedestrian Dead Reckoning)
    • On 1D PDR method, NavCog also handles edge as one-dimensional line as same as 1D method. Acceleration sensor data will be used for localization in addition to beacon data.

NavCog Version 3 supports the 2D mode. See wiki for setting up NavCog Version 3.

  • 2D
    • On 2D method, NavCog handles edge as two-dimensional line. Acceleration sensor data will be used for localization in addition to beacon data.


Please prepare the following items to create and test your navigation map.

  1. Mac
  2. iPhone 6 or later
  3. NavCov app downloaded from App Store (URL TBD)
  4. Bluetooth LE Beacon (see Appendix)
  5. Floor plan images (optional)
  6. Long measure tape & sticky tape

Overview of Building Map

NavCog App is utilizing Bluetooth radio wave signals to estimate user's location. You can easily create navigation map with the following steps.


  1. Choose target area and navigation routes in your site (Sec. 2)
  2. Distribute beacons around the routes (Sec. 3)
  3. Prepare fingerprinting (*1) data for localization (Sec. 3)
  4. Build map data for the app (Sec. 2)
  5. Test the app with your map (Sec. 4)
  6. Submit the map data for public use (Sec. 4)
  7. Let your blind users try blind navigation in your site (Sec. 5)
