Link views and multiple responses

For this example we will demonstrate Image Quizzer's ability to link the viewing windows so that images will scroll together. Also, this example shows how different pages can be set up to allow the user to modify their response when using the Previous and Next buttons.

The two Page attributes being highlighted are:

1. LinkViews
2. AllowMultipleResponse

Prep

Download and save the CT-MR Brain dataset as described in the sample data section.

Save the dataset to a subfolder under ImageVolumes/ as shown.

.
└─ ImageQuizzerData/
      └─ ImageVolumes/
          └─ CT-MR Brain/
               ├─ CTBrain.nrrd
               ├─ MRBrainT1.nrrd
               └─ MRBrainT2.nrrd

Script example

For this example, the first page is set up for linking views and also allows for multiple responses. The second page has both of these attributes turned off.

Results file

The results file that follows shows that the user answered questions for both pages 1 and 2. Then before pressing the Finish button, they pressed Previous and changed the checkbox selection. This can be deduced by following the ResponseTime attribute in each Response element.

After changing the selection for page 1, the user advanced to page 2 using the Next button and found that no modification to the original response was not allowed - the quiz question was greyed out.

Note the double Response elements for each Option in the first page where the 3rd question was modified.
