questfox mission Speech in Research for iOS completed #questfox FeatureAlert

Speech in Research also on iOS with questfox

Speech questionnaires with Apple iOS devices now available in questfox.

Since 2017 we already offer speech interviews on mobile or desktop devices powered by questfox. In 2019 we were awarded with the Best Practice Award from the German Society for Online Market Research (DGOF) for our study comparing the input of classic type-in keyboard input vs. voice input and video input with transciption of the speech. The study was one of its kind and a breakthrough in innovative online research.

But two years ago – for the first time in years – we were not able to follow our basic “device agnostic” paradigm as it was not possible to use these crazy new speech features on all devices available. The market driven fight between major players of the IT industry makes it necessary to cope with different approaches of technology.
Finally our fantastic development team made it happen. We are proud to offer the questfox feature set for speech in research questionnaires now to the Apple/iOS universe too.

Decision makers run on Apple devices

Even though the Apple world is a minor group in terms of market share and representativeness in market research, most of the decision makers run on Apple phones. These were the sceptical people not believing in our technology as we could not offer it to them. Hope to prove you wrong one more time.

The only excuse now left to not use speech questionnaires in research powered by questfox is a missing willing to innovate. All innovators are invited to work with us on new forms of research. The tech base is just the fundament to build new interactions in research far beyond the classic Likert scale.

Constant battle to innovate in research

The next battle we will be fighting in this field is to make change happen. A new paradigm of social interaction is available now. We are looking for totally different ways of asking questions. Leaving technology barriers behind now we are exploring new horizons.

All existing achievements of questfox are now available on some more millions of devices.
The 120 languages covered by questfox can now be used on iphones and Mac computers in Safari too. We will now be testing the settings where speech is still not possible and report on this. For sure there will be incompatibilities with older systems and older browers. But time is on our side….

Please update to the latest iOS 14 to be up to date for security reasons and to be able to participate in studies with voice. The new questfox features from covid year 2021 are probalby not working on Windows 95 and Internet Explorer. So please do not ask us if we can time travel to support stuff you should have updated long time ago. This is the time for change. So please also adopt and let us talk how we can change the world to make it a better place.

Why Speech in Research?

We believe (and can prove with data) that this technology opens the door to new kinds of research. Quant research will now be able to integrate more qualitative input. More data can be captured in less time. This is a way into sustainable research we definitively need.

#Gurkensalat: Historical innovation in market research with questfox

“Das Pferd frisst keinen Gurkensalat.”
Translation: “The horse does not eat cucumber salad.”

This is the first sentence ever spoken in telecommunications as used by the German inventor Philipp Reis, who invented the phone call years before Graham Bell had the idea patented and became world famous.

Reis called his invention “Telephon” which later became the international name for something we use on a daily basis.

Voice interaction is going new ways. We are always trying to change the market research game and are very proud to present the first pure digital speech interaction in market research powered by questfox.

The new questfox feature of Text2Speech lets you create speaking questionnaires. Any text implemented is read out loud to the respondent by an artificial voice. Together with our already developed Voice question type functions we are looking forward to see complete questionnaires without ever using text anymore.

We are not yet there, but this is an attack on the classic telephone interview. We are not only looking for the reduction of cost when developing such an approach, but we are also trying to create interviews of higher quality because of the standardization of the spoken interview.

A big plus is the opportunity to use questlogix and analytic tools in the background. A fully functional digital voice interview would outperform the classic approach by far. It is faster, of higher quality and definitively cheaper.

To honor Philipp Reis, the courageous German inventor, we invite you to test these functions under the hashtag #Gurkensalat. Let us see, what this technology brings.

At the moment we start doing our testing in the German language only. English is soon to follow with the opportunity to select different voices.

How to manipulate fonts in CSS with questfox

It is possible to use different fonts in a questfox survey.

If you have a corporate font that is not publicly available you should talk to your representative to help install this font on the server.

Public fonts:

If you plan to use a font out of the variety that Google is offering in the goolge font project we recommend to chose a font from this website:

https://fonts.google.com/

Import font on the fly from google servers

/*Import of font into project */
<style>
@import url(‘https://fonts.googleapis.com/css2?family=Satisfy&display=swap’);
</style>

/*Definition of font for your project */
body { 
    font-family: ‘Satisfy’, sans-serif;
}

How to manipulate the question text on top of the question?

.questionText > span > p{
font-size: 1.5em;
font-weight: 600;
}

/*Definition of font */
body { 
    font-family: ‘TeleNeo’, sans-serif;
}


CSS Selectors in questfox

  • There are two ways to affect the text layout of questfox projects

A) Definition of CSS on client area level (-> Branding)

B) Definition of CSS on project level (-> Project characteristics)

  • All text elements in questfox can be modified via CSS
  • There are certain CSS selectors for the various text elements in questfox
  • Some text elements share the same CSS selectors
  • Various properties can be applied
  • A typical questfox project with different question types and decision trees demands up to 16 different CSS selectors


How to format the text underneath indicating Imprint and Data Security Rules

CSS selector: .branding_sub_text
Effect: Defines the small branding text on the down right side of the project window
CSS code example
.branding_sub_text
{
color: #022D61;
font-size: 1.2em;
font-weight: bold;
text-align: left;
}

CSS for Analytic Hierarchy Process (AHP) / Decision Tree

The AHP is a very specific idea inside of questfox. Following the algorithms of Thomas L. Saaty we developed out own approach of how to ask questions in the pairwise way.

CSS selector: .ahp_context
Effect: Defines the title text of a decision tree question
CSS code example
.ahp_context
{
color: #022D61;
font-size: 1.2em;
font-weight: bold;
text-align: left;
}
.ahp_context
CSS selector: .ahp_contextDetail
Effect: Defines the description text underneath the title of a decision tree question
CSS code example
.ahp_context
{
color: #022D61;
font-size: 1.2em;
font-weight: bold;
text-align: left;
}
.ahp_contextDetail
CSS selector: .ahp_question
Effect: Defines the question text of a decision tree question
CSS code example
.ahp_question
{
color: #022D61;
font-size: 1.2em;
font-weight: bold;
text-align: left;
}
.ahp_question

CSS selector: .ahp_versusText
Effect: Defines the versus text of a decision tree question
CSS code example
.ahp_versusText
{
color: #022D61;
font-size: 1.2em;
font-weight: bold;
text-align: left;
}

.ahp_versusText
CSS Selectors #ahp_option_left #ahp_option_right
Effect: Defines the versus text of a decision tree question
CSS code example
#ahp_option_left
{
color: #1d537f;
font-size: 1.4em;
font-weight: bold;
text-align: right;
}
#ahp_option_right
{
color: #1d537f;
font-size: 1.4em;
font-weight: bold;
text-align: left;
}

Using your own font in questfox

Fonts can support or destroy your research project

It is possible to integrate your own font into a research project.

Make sure that your font makes sense in research terms. Sometimes it is also helpful to not disclose who is asking by exactly not using your own corporate identity elements.

There are several ways to do that.

Importing Webfonts into questfox

You can integrate fonts which allow the using via internet. Please see the description of how to do that on fontawesome.

Import of Google Webfonts into CSS is explained here:

https://www.w3docs.com/snippets/css/how-to-import-google-fonts-in-css-file.html

Inside of the google fonts there are different ways of how to import a font into your project.

@import url(‘https://fonts.googleapis.com/css2?family=Lora&display=swap&#8217;);

Using your own non-public font

A lot of companies do have their own corporate design font. In case you plan to use that font this is the way:

  1. Make sure that you have the right to use the font.
  2. Install the font on an accessible server
  3. Integrate the font into the questfox project CSS

Example Official Berlin Font “Berlin Type”

Sometimes fonts are published for the use. Make sure that you do cover the licence agreement when using this font for market research.

We downloaded the font of the Berlin Senate here:

https://wir.berlin/fileadmin/downloads/Wir.Berlin_Schrift.zip

The font is installed on the questfox server now.

You just have to implement the following code into your project’s CSS

body {
font-family: ‘WirBerlin’, arial;
}

In case some computers/phones are not able to use this font there is a second font defined that should be available on any device (arial in this case).

Have fun creating more beautiful looking questionnaires.


questfox server now operating on german premises

The GDPR rules are already implemented into questfox for years. But still more and more german clients ask about the server infrastructure as they need to include this into their contracts.

From today on questfox.com is running on a Microsoft Azure server system located inside of Germany.
It does not change anything for the user, but for some people it just feels better. 😉

Independent from this step we continue to be devoted to the highest standards of data security. After 15 years of operating the questfox system we know that the user itself is the risk category no. 1. So keep your passwords secure and never share your logins with anyone.


NEW Maths function in questfox

Mathematics is clearly defined for centuries now. questfox is offering you a set of mathematical operations since the beginning of our development from the standard toolbox of database manipulation.

See our special questfox functions under https://questfox.news/2021/03/08/how-to-calculate-with-missing-values-in-questfox/

Besides those questfox specific procedures we are using a bunch of functions to interact with mathematics. The Jace.NET framework is now used to support your calculation inside of questfox. More info under https://github.com/pieterderycke/Jace/wiki/Standard-Functions

Here is the list of functions so far to be used inside of questfox calculations.

Syntax check from ln to loge

Please check your questfox project for the correctness of the syntax. For example: The formerly implemented function ln is now called loge. You now need to switch to this new version in order to perform those calculations in the future with questfox.


How to calculate with missing values in questfox

We are also adding functions to this world of math by creating our own formula for the market research world being able to create a sum or an average respecting the fact, that someone did not see or answer a question. Our operations for the so called “missing values” help you to analyze correctly long before you can do similiar things with sophisticated tools like SPSS. See our idea of how to treat missing values https://questfox.news/2021/03/08/missing-values-in-market-research-with-questfox/

When you then want to calculate with a variable that contains “missing values” you will face trouble in the analysis. questfox has two special functions to take that into account.

The syntax is described here

qf_avg()Returns the average value of the input values (seperated by comma) and excludes missing, not seen and not answered values.
qf_avg(@81c4af14-4857-49b8-9dd7-449b33e73e60@ , @7151c6d2-48af-4619-8318-39b62aa99b07@)
qf_sum()Returns the sum of the input values (seperated by comma) and excludes missing, not seen and not answered values.
qf_sum(@81c4af14-4857-49b8-9dd7-449b33e73e60@ , @7151c6d2-48af-4619-8318-39b62aa99b07@)
Calculations with missing values.
Live Calculation in questfox

We suggest to ad an invisible number inside the questionpage and calculate right into that hidden variable. You can later use this value as a trigger for questlogix or to show this value live to the respondent.


Missing values in market research with questfox

The phenomenon is not recent. People do not answer to questions. If someone does not answer to a question we are talking about so called missing values.

Also see the Wikipedia article: https://en.wikipedia.org/wiki/Missing_data

questfox knows 3 different kinds of missing values.

Missing value -99

someone clicked explicitly on “no answer”

Missing value -77

the question was not even shown to the repsondent (due to skipping/hiding procedures)

Missing value -88

classic missing value meaning the question was shown, but the answer was not mandatory so the respondent could click through

A good idea is to make someone click on each question, but this means that you will have to add the option “no answer / do not want to tell” to every answer where you require a mandatory click. Even if you do some of the questions or items will not be shown and therefore create a Missing value (-77).

Why is it negative with two digits in questfox?
The answer is pretty simple. If you use a scale from 1 to 5 and your default missing value is 9 (as some of us learned in their statistics class), you may not realize that you have an issue with missing values in your report. In the questfox default you would easily see that something is wrong in your definition of missing values.

These three default values are assigned to every question type and can be changed under “Define Missing Values” in the edit answer section.

3 types of missing values in online research

When using SPSS these values can be defined as discrete missing values.

Now it is up to you if you can force your population into answering all the questions.
