Secondary Screen Support provides the ability to have an interview setting where the respondent can be handed a separate Android device (phone or tablet) so that during the interview so the interviewer can directly present images or videos directly on the participant's device. This provides a way for the interviewer to listen to feedback provided by the respondent to record their experience without having to hand over their primary interviewing device.
1: Requirements
Both Primary and Secondary device need to be Android devices (as the app is using an Android-specific method to connect)
Wi-Fi must be On and Location enabled on both devices. (No Wi-Fi network is needed for either device as Secondary Screen Support uses Wi-Fi Direct peer-to-peer.)
Only images or videos can be shown. Files must be from the File Library (so they are available locally/offline).
Both Primary and Secondary device need to have the CAPI app installed and the same survey assigned. (You can log into both devices with the same CAPI Interviewer to easily have the same survey assigned to both devices.)
2: Survey Design
Use JavaScript within the survey to call the new functions:
CapiApp.ShowImage(FileLibraryPath)CapiApp.ShowVideo(FileLibraryPath)
An example of this is to use an HTML button on any question text, for example:
<button onclick="CapiApp.ShowImage('/isa/BDJPFRDMEYBPBKLVADAYFQCDAVIOEQJR/capicommon/map.png')">Show Image</button>
When the button is tapped, the image/video is immediately shown on the secondary device (using a webview).
