Why use QR codes?

FizziQ uses QR code technology as a means of exchanging experimental protocols. The QR code system was invented in 1994 by Masahiro Hara of the Japanese company Denso Wave. The use of QR codes is free of rights. The QR code has several advantages that guided this choice for FizziQ. The first is that the technology allows the exchange of small text files (less than 4 kb) without using the Internet. In many countries, and often also in schools, pupils do not have access to the internet. T he experimental protocols are generally small files. On the other hand, the technology is very widely used, especially for payment in many countries and all smartphones are equipped with a camera. There are many free tools on the internet to generate a QR code online.

​

How to generate the QR-code of a FizziQ protocol?

There are two ways to create a QR code protocol in FizziQ:

1. From the application. The teacher can create a protocol or edit an existing protocol, then he can export this protocol in QR code format, or in text format .

2. From any QR code generator on the Internet, following the FizziQ protocol format rules below.

​

What is the format of the FizziQ protocols?

The FizziQ format is defined by specific fields which are separated by the "//" character combination.

The fields are as follows and the information must be placed in the correct order:

1. The sequence begins with the code: "Fizziq"

2. The title in text format

3. The purpose of the protocol in text format

4. The different steps of the protocol classified and separated by the separator "//"

​

An example ?

For example, consider the following protocol:

The title of the experiment is "The sound", the subtitle "Amplitude and frequency work", and two steps "Choose a musical instrument for which you want to analyze the sound" then "Which instrument from FizziQ can you use to measure the fundamental frequency of a note on your instrument? ".

You can create a QR code by typing, in the text field of the "QR Code" generator available on the internet, the following text:

"Fizziq//The sound//Work on amplitude and frequency//Choose a musical instrument for which you want to analyze the sound//Which FizziQ instrument can you use to measure the fundamental frequency of a note of your instrument?"

To find a QR code generator, type "QR Code generator" in the browser's search bar .

​

What are the limits of the QR code?

Commonly used QR codes can contain up to 4296 alphanumeric characters. However, for use in FizziQ, we recommend that the size of the protocol, including separators, not exceed 2000 characters.

​

Do other applications use this format?

The FizziQ protocol format is not proprietary. We hope to see the emergence of a database of experimental protocols that can be used for multiple applications.
