Navigation QR code<

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.

What mobile marketers use to get their message to mobile markets.

A comparison between 2010 and 2011 deployed mobile marketing tactics. I'm sure that 2012 will again see an increase in the use of QR codes.

   2011    2010

In 2010 no one bothered to check the use of augmented reality, so data is missing for this year.

Interesting to note is that barcode scanning is up 15% (this includes QR codes, MS tag and other proprietary barcoding technology) and outperforms any other technology used between 2010 and 2011 and I expect it to increase even more in 2012. Mobile apps are also still a popular instrument for branding and marketing.

SMS marketing that was always seen as an urgent and immediate communication channel has declined the most. Even though it is the fastest and simplest way to set up, use and to communicate to mobile devices, I can only imagine that the costs per message in combination with limited interaction and presentation options are the reason it is being abandoned by marketers.


QR Code Fonts

QR code symbols and font glyphs

Imagine being able to place your favorite QR codes in any document anywhere at the touch of a key on your keyboard.  Considering that printed QR codes have the most intrinsic value it nearly seems fundamental that these should be available for publishing at a key stroke.

Having your QR codes as a font means you can publish them in any document at any time and at any size. So whether you place your vCard QR code at the bottom of all your stationary, or as a designer put your Facebook like QR code on a giant poster, the same QR font set is perfectly suitable. This is because fonts are scalable to any size, from micro printing to massive billboards the font will always give a perfect sharp representation.

How QR code fonts work

A QR code is a two dimensional bar-code built with square blocks. Each block is made of four lines and then filled with a colour, preferably black. All the blocks of a QR code are placed as a 'glyph' into a 'font' and assigned to a specific letter of the alphabet. Consider placing your Twitter QR code under the letter 'T' and the Facebook QR code under the letter 'F'. In this way it is possible to place any QR code of any complexity under any key of your keyboard.

Even designer QR codes can be used as a font provided the design in monotone (one colour)

QR code font example

Provided is a free downloadable TrueType QR code alphabet font that instead of letters and numbers has a QR code that represents each letter and number (ASCII only for now). I don't think it idea to use to publish your next novel, but does show that QR codes are perfectly at home and usable as a font.

  • Mac compatible

What is QR code error recovery

Error recovery in QR codes allows pieces of information in the QR code to be damaged or missing and still have the ability to be read correctly. In a nutshell, it does this by using some very clever complex algorithms to place 'compressed duplicated' information in different places of the QR code, so if some data goes missing it can (try too) reconstruct the missing pieces using the remainder of the existing code.

There are four different settings available that can be chosen from before creating the QR code, Each one allows for a different amount of data loss.

QR Code Error Correction 7% QR Code Error Correction 15% QR Code Error Correction 25% QR Code Error Correction 30%
 7% Loss Recovery  15% Loss recovery  25% Loss Recovery  30% Loss Recovery

So why not always make QR codes that support 30% loss recovery?

The higher the damage recovery percentage, the more room is needed inside the QR code to encode and store the information vital to recovery. Below is a URL QR code of the same URL and created using the four different error compensation selections.

QR Code using 7% Error Correction QR Code using 15% Error Correction QR Code using 25% Error Correction QR Code using 30% Error Correction
 7% fault tolerant  15% fault tolerant  25% fault tolerant  30% fault tolerant

Scan any of the four codes and they will all take you the same URL. the left QR code is more sensitive to damage then right one. Lets put this to the test by taking the first and the last QR code and 'damaging' them proportionately in favor of the smaller QR code.

Non Readable Damaged QR Code Readable Damaged QR Code
 Bad QR code  QR code still readable

Clearly the 30% fault tolerant QR code on the right still scans even though a big piece of its data has been obscured, while the smaller code on the left no longer works at all, even though visually it has less data damage.

This same technique is used to create designer QR codes. Making QR codes pretty by damaging the data but at the same time keeping them scannable and working.

How to use QR code error recovery

When creating QR codes for example business cards, the chances of it getting dirty are rather low and you want the QR code as small as possible. Here a standard 7% error threshold is enough and very suitable for cards and other printed matter. However if are going to use QR codes outdoors, on cars and trucks or any place where data may be obscured by dirt then setting the error correction to a higher setting is advisable although chances are you will land up with a bigger image.

TIP: Do not believe everything people tell you about QR codes...ask them to prove it and show you!
Myth: 'you can tear a QR code in half and it can still be read'
Here's what a British 'technology consultant' had to say during an interview on business hub radio...
