 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: 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 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.

 **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. **Note:** Not every questionnaire is suitable for filling out on the small display of a smartphone.

 +Sometimes it is necessary to reject participants who want to access the questionnaire with a desktop computer or laptop. This is similar to the procedure described above ([[#filter_for_smartphone users|Filter for smartphone users]]).
  
 +  * Unordered List ItemA functional block of type "Device and transmitted variables" is required to determine the //format// of the device and place it before the filter in the questionnaire (see [ #filter_for_smartphone users|above]]).
  
 +In addition, a text is created ([[[:en:create:texts]]]), which for example has the identification "GG02" and politely informs the participant to edit the questionnaire via mobile device.

-Mehrwellige Befragungen: Mobile Experience Sampling Method (MESM) 
-Mitunter ist es notwendig, Teilnehmer abzuweisen, die mit einem Desktop-Computer oder Laptop auf den Fragebogen zugreifen möchten. Dies erfolgt ähnlich wie oben (Filter für Smartphone-Nutzer) erläutert. 
  
-Benötigt wird ein funktionaler Baustein vom Typ „Gerät und übermittelte Variablen“der das Format des Geräts ermittelt und vor dem Filter im Fragebogen platziert wird (s. oben). +For the following code exampleit is assumed that the block "Device and transmitted variables" has the identifier "GG01" and the text has the identifier "GG02"The following PHP code is placed as the first element on the first page of the questionnaireIt already integrates "GG01" using '[[:de:create:functions:question]]]''so that the module "GG01" no longer needs to be placed separately in the questionnaire.
-Zudem wird ein Text angelegt (Texte im Fragebogen), der z.B. die Kennung „GG02“ hat und den Teilnehmer höflich darauf hinweist, den Fragebogen via Mobilgerät zu bearbeiten. +
-Für das folgende Code-Beispiel wird davon ausgegangen, dass der Baustein „Gerät und übermittelte Variablen“ die Kennung „GG01“ hat und der Text die Kennung „GG02Folgender PHP-Code wird als erstes Element auf der ersten Seite des Fragebogens platziertEr bindet „GG01“ bereits mittels question() einsodass der Baustein „GG01“ nicht mehr gesondert im Fragebogen platziert werden muss.+

 } }
-Hinweis: Dieser PHP-Code erlaubt das Ausfüllen mittels Tablet. Um auch dies zu verbieten, ergänzen Sie eine Prüfung or (value('GG01_FmF') == 2) im IF-Filter.+</code>
  
-Hinweis: Der PHP-Code soll ein versehentliches Ausfüllen auf dem falschen Gerät vermeiden. Durch gezielte Manipulation können Teilnehmer den Fragebogen u.U. auch auf einem Gerät ausfüllen, das eigentlich nicht zugelassen werden sollte: Einige Browser (z.B. Chrome) können ein Mobilgerät emulieren, andere Browser können eine gefälschte Browserkennung übermitteln. 
  
 +**Note:** This PHP code allows filling using Tablet. To prohibit this too, add a check or (value('GG01_FmF') == 2) in the IF filter.
  
-Fragebogen nur für Computer 
-Einige Inhalte sind für Smartphones oder sogar für Tablet-Computer nicht geeignet. Das können zum Beispiel sein… 
  
-Komplexe kombinierte Fragen, die kompakt detaillierte Informationen abfragen +**Note:** The PHP code is designed to avoid inadvertent filling on the wrong deviceThrough targeted manipulationparticipants may also be able to fill out the questionnaire on a device that should not be allowed: some browsers (e.gChromecan emulate a mobile device, other browsers can transmit a fake browser identification.
-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) +
-Testsdie eine Tastatur und/oder Maus als Eingabegerät benötigen +
-Videos, die in einer ruhigen Umgebung (nicht im Bus des ÖPNV) an einem Computer mit Lautsprechern angesehen werden sollen +
-Abbildungen von Internetseiten, wie sie auf einem normalen Computer aussehen, deren Inhalte auf einem kleinen Smartphone-Display nicht erkennbar wären +
-Mittels Filter kann man Teilnehmern, die ein Mobilgerät nutzen, freundlich mitteilen, dass dieses zum Ausfüllen nicht geeignet istDas Vorgehen ist äquivalent zum Abweisen von Teilnehmern in Smartphone-Studien (soben).+

 +  * Videos to be viewed in a quiet environment (not on the public transport bus) on a computer with speakers 
 +  * Images of Internet pages as they look on a normal computer whose contents would not be visible on a small smartphone display

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

 +Use the **Variables overview** to determine the possible values of the device format for the filter. Code 4 describes a mobile device whose format cannot be exactly determined, Code 5 describes in Smartphone.
