Active Navigation via QR codes
Mobile devices with GPS (Global Positioning System) capabilities and that have one or other navigation application onboard can make use of QR codes to activate as example, a route planner, for realtime navigation activation.
Like the sextant (six piece od a circle measurement) a nautical and astronimical device to determine the longitude using Greenwich time, our modern electronic devices need three components to make it work.
- GPS receiver and processor
- Navigation and mapping application
- QR Code reader capable of understanding geo-encoded data
Creating navigation QR codes
QR4 provides a free QR Code Navigation Generator
There are other geolocation and routing options
For devices that do not have GPS, nor mapping capabilities, but do have a QR code reader the use of an Internet service is the best choice to show where the co-ordinates you have encoded are on the globe. It stands to reason that navigation will need to be done externally by entering your current location in the online service.
The requirements for this type of service are:
- Available Internet connection (via any type of connection, teathered or wireless)
- QR code reader capable of understanding a request to go to a resource on the Internet
Passive geolocation and routing
QR4 provides a free QR code Geographic Generator
So now you can implement active and passive (via an external service) geo-location using QR codes.
Which type of QR geo-coding is best to use when and where?
Let me start off with: If it's printed, painted, projected or anything in the analogue world...use QR codes. If it's digital and portable DON'T!
Both types have their merritts. If you want people to know where you are, play safe and use the passive version, knowing that if that service fails or changes it's way of working, your published and printed QR codes could become totally useless. If you need to guide people to your location the navigation QR code is your best option, but will only work with mobile devices meeting the three criteria for direct navigation ability. The choice is yours. As complete measure you could consider providing both geo-location types to service as wide an audience as possible.
