-====== Questionnaires for Smartphones ======
+======= Surveys for Smartphones =======
-Modern mobile phones often offer Internet access and an Internet browser. So what could be more obvious than using these smartphones for surveys? There are three different cases:
+The proportion of participants filling out a questionnaire on a mobile phone varies significantly depending on the study. However, in most studies, it is essential to assume that a significant portion of respondents will complete the questionnaire on a small display. In practice, the following scenarios arise:
+  * ** The questionnaire should work everywhere**\\ Often, participants should just be able to complete the questionnaire - regardless of whether they are using a laptop, tablet or smartphone.
+  * **Questionnaire for mobile devices only**\\ Some study designs, such as diary studies or mobile experience samples, are designed to be completed on the mobile device only.
+  * ** Questionnaire for computers only**\\ Other study designs are unsuitable for smartphones, e.g. when a task requires a great deal of information to be displayed on the screen at the same time or when response times are to be recorded at the touch of a button. In this case, you want to make sure that the questionnaire is not filled in on the smartphone.
+**Tip:** You can also test the display for mobile devices on your computer. Look for the developer tools in your browser (Firefox, Chrome) ([[:en:general:browser-tools]]). There, you will find a switch to the smartphone simulator.

-====== Questionnaire for all devices ======
 **Note:** Not every questionnaire is suitable for filling out on the small display of a smartphone. Long scale batteries (more than 10 items) are no more fun on the small display than long question texts/instructions or long stimulus texts. Not to mention the fact that you like to fill out a 5-minute questionnaire on the bus, but probably not a questionnaire that takes 30 minutes. Therefore, scientific questionnaires are often not suitable for the small mobile phone display, regardless of the presentation.
-Approximately every fifth person who completes a questionnaire on SoSci Survey uses a mobile device. Tablets are unproblematic: They offer sufficiently large screens and all types of questions in SoSci Survey can be answered just as easily by touch (touch display) as with the mouse. With smartphones, however, the small display can become a problem.
+The percentage varies between 0 and 100 percent depending on recruitment -- but on average, 4 out of 10 people use a smartphone when they access a questionnaire at www.soscisurvey.de (data from the second half of 2018). This does not include tablets, which are unproblematic: : They offer sufficiently large screens and all types of questions in SoSci Survey can be answered just as easily by touch (touch display) as with the mouse. With smartphones, however, the small display can become a problem.

 We recommend the following optimizations so that the questionnaire can be completed sensibly on smartphones:

   * You may want to use "larger" or "very large" selection fields in the  [[:en:create:layout]]  in the tab //Basic settings// for the option Type of //selection fields// so that they are easier to select.
   * If you use audio or video files, integrate them using HTML 5 ([[:en:create:media]]) and make sure that all video formats are converted so that they can also be played on mobile devices (pixel size, data rate, etc.).

-====== Filters for smartphone users ======
-With the question type "Device and transmitted variables" you can find out whether a participant completes the questionnaire using a smartphone:
+======= Filters for Smartphone Users =======
-  * Create a question of the type "Device and transmitted variables".
+With the question type [[:en:create:questions:client|Device and Transmitted Variables]], you can determine, among other things, whether a participant is completing the questionnaire using a smartphone:
-  * On the Device tab, select Format.
-  * Drag the question to the page where you want to filter - or to the first page of the questionnaire.
+ * Create a question of type [[:en:create:questions:client|Device and Transmitted Variables]].
+ * In the //Device// tab, check the //Format// option.
+ * Drag the question to the page where you want to apply the filter – or directly to the first page of the questionnaire.
 This question stores whether the participant's browser identifies his or her device as a computer, tablet or smartphone. For example, if the question has the identifier "GG01", the following PHP code shows smartphone users the question "FM01" and all other users the question "FS01".

+==== Separate questionnaire ====
 It is possible to submit a completely different questionnaire to smartphone users than to other users. This can be useful if, for example, other content is to be displayed on a larger scale and/or if the questionnaire is to use a completely different layout for smartphone users (e.g. "SoSci Smartphone").

+You can use filters to inform subscribers who use a mobile device that it is not suitable for filling in the form. The procedure is equivalent to rejecting participants in smartphone studies (see above).

-Rangordnungs-Fragen, die viel Platz benötigen, oder Fragen, die auf Basis von Reaktionszeiten eine implizite Einstellung messen sollen, z.B. ein IAT (beides ist auch auf Smartphones prinzipiell möglich aber evtl. aus methodischen Erwägungen nicht erwünscht)

-Mittels Filter kann man Teilnehmern, die ein Mobilgerät nutzen, freundlich mitteilen, dass dieses zum Ausfüllen nicht geeignet ist. Das Vorgehen ist äquivalent zum Abweisen von Teilnehmern in Smartphone-Studien (s. oben).
