When the picture is accepted, the user will be redirected to a loading activity which uploads all the pictures and pulls all the pictures in the server.

The next activity is the pre-survey questions (Figure 6). There are two types of questions; multiple choice and fill text. The user must provide an answer to all the questions to continue with the survey.

At this point, the user has provided all the pre-survey information and the actual survey begins. The user sees pictures of some other users (Figure 7). Note that the maximum number of pictures can be determined by the researcher while creating the study. It can be found in the study info page in the ResearcherUI. The user has to drag the image to one of the options; recognize or don’t know.
