Set up an interviewer tablet by scanning a QR-code

When an interviewer launches the Interviewer App for the first time she needs to provide the following three parameters:

• URL of the server (synchronization point),
• login of the interviewer (account name on that server),
• and the password of the interviewer.

Typing in the server address may be time consuming and prone to errors, so to simplify the process Survey Solutions permits entering this information by scanning a barcode. This is especially useful for the ITs setting up a large number of tablets in the office for many interviewers at the start of the survey.

Multiple interviewers using the same tablet

Survey Solutions uses device tracking mechanism where for each interviewer account there is an indication of the currently linked device. In short this means that at any moment any interviewer may be utilizing only one device for data collection. Re-linking of the devices is possible, but it has some important consequences (explained here). 

At the same time it is still possible for multiple interviewers to use the same tablet for data collection, but every interviewer must have a different user account in the Android operating system to permit this. If this is not done, once the first interviewer initializes the connection, his name will be fixed in Survey Solutions, and other interviewers will not be able to log in. Refer to the Android OS documentation for supporting multiple users on the same tablet.

Updating the Interviewer application

Why update

There are several reasons why:

• New features. With most releases of Survey Solutions, new features are introduced–new question types, new user interface, new actions, etc. To take advantage of new features, the Interviewer application must be updated.
• Bug fixes and performance improvements. Each releases of Survey Solutions contains numerous bugs and performance improvements. To avoid bugs and ensure the best performance, the Interviewer application should be updated regularly.
• Break with backwards compatibility. In general, older versions of the Interviewer application will continue to work with an updated Headquarters server. In some cases relatively rare cases, however, new features break this backwards compatibility. When this happens, the Interviewer application needs to be updated so that the tablet can continue communicating with the server.

When to update

At a minimum, the Interviewer application should be updated every month. Every two months, typically a new version of Survey Solutions is released. In the intervening time, smaller updates and bug fixes are released.

Interviewer App interface language/localization

The Interviewer application responds to the device language setting of the mobile device. Localization affects the interface of the application, such as menus, dialogs and application error messages. The languages currently available are listed in the localization overview article.

The exact steps to change may differ slightly for different device models and operating system versions, but described generically in this Android HelpCenter article.

Note that you can still design the questionnaire itself in any language, including the texts of the questions, their options, instructions, and validation messages. Survey Solutions also allows multilingual questionnaires, which allow switching the language even during the interview.

Synchronization & Completing the Interview

1. Logging in

You can log in using the user name and password that you received from your supervisor. Tap on the eye icon to see your password to make sure you have entered it in correctly.
  
If you cannot log in, although you are sure that the username and password are correct, synchronise the tablet (see next step)

2. Synchronize

You should synchronize your tablet as often as your supervisor has instructed you to.
 
Synchronization requires internet access. To synchronize, press the “Synchronize” button at the top right corner of the toolbar. The results of the synchronization will be displayed: how many new assignments were received, how many were received as rejected and so on. 

Download and Install the Interviewer Application

Step 1: On the home screen of the tablet, click on the Applications button. The button is usually located in the middle of the bottom toolbar and the icon is a circle with six dots. In the applications menu, Select Settings. Select Security and make sure that Unknown Sources - Allow installing application from sources other than the Play Store is selected/ticked.
