This is an overview of the participant viewing process. All screens are shown here, but note that each participant will only see some of these screens depending on study setup and other events. In the descriptions below, we have added *optional* to screens that are not shown to all participants.

In total the viewing process takes between 5 and 10 minutes, depending on the number of questions asked and the complexity of the media items displayed.

There are 2 main exit points from the process – screenouts and completes. Note that not all completes may be successful, but “completed” viewers have made an effort to complete the survey and have spent time on it. Screenouts are only generated at the earliest stages of the process. Exits from the viewing process are annotated [REDIRECT] because at these points we can redirect back to a third-party recruiting source.

Note that viewers may simply choose to stop completing the process at any time, in which case these views will be marked as “incomplete”.

Landing Page / Consent

The first page participants see is the consent page. This explains that they must have a webcam, and not wear glasses. They can opt-out at this stage.

Cancelled / Screenout [or REDIRECT] *optional*

If participants elect to screenout at any stage, they will see the viewing cancelled page. This is the end of the viewing session. If participants were sourced from a third-party survey system, they will NOT see this page but will be automatically redirected back to the original panel provider with a status of “screenout”.

Rejected: Bad Device / Browser [or REDIRECT] *optional*

If the system detects an incompatible device or browser (i.e. Not Chrome on an x86 compatible device) then participants will be automatically redirected to the “rejected” page shown below. Here they have the option to try again with the right browser, or click “No thanks” which triggers the screenout logic above.

Checklist

If viewers decide to participate, they will be shown a more thorough checklist of 5 steps to prepare. Getting good lighting and an upright seating position are key.

Add Browser Extension *optional*

If viewers have not used EyesDecide before, they will be prompted to install an xLabs compatible browser extension. This occurs inline with 2 clicks. If an extension is present, this screen is not displayed.

Adjust Page Zoom *optional*

If the user has set the page zoom to a value other than 100%, they must change it back now. This ensures we can reconstruct the appearance of the page correctly afterwards. This screen only appears if the page is not 100% zoom already.

Survey before Viewing *optional*

If the study includes one or more “before viewing” survey questions, they are presented here. If there are no questions, this screen is not displayed.

Calibration begins

This screen is prompts users to prepare for the calibration process. It also gives the camera time to start. All exits after this point will be recorded as “complete” or “incomplete”, not “screenout”.

Camera Check

The camera is then checked to ensure the face can be tracked accurately.

Camera Problem *optional*

If the face cannot be detected, you will see an error message. Try changing the angle of the camera so that the face can be seen.

Calibration Clicks

This is the main part of calibration. The viewer must move the mouse over, wait and then click 30 red dots. The red dots say show the number of clicks remaining (i.e. 30 the first time). When the mouse is moved over the red dot, a green circle starts to draw around the circle and the message changes to “look”. When the circle has finished, the dot becomes green, and the message becomes “click”.

The grey arc around the dot is an indicator of overall progress. It becomes shorter as the clicks are completed.

Camera Debug Page *optional*

If there is a persistent problem with the camera image, viewers will be taken to the camera debug page. This attempts to fix the problem by showing viewers the video from their camera and providing a series of prompts.

Viewing Instructions (HTML)

After calibration, the viewing instructions are displayed. Viewers must click the “Got it” button to proceed.

View Media Items

All the media items are then displayed. The order and duration of media items depends on the workflow configuration of the study. Viewers can scroll and click while viewing. This phase may be up to 1 minute in duration, much longer than the other screens.

Accuracy Test

After viewing the media, the viewer is requested to click 5 additional red dots. This is used to conduct an accuracy test to ensure the gaze data is of good quality.

Upload Viewing Data

Finally, the viewer is prompted to upload the viewing data. This may be up to 3MB in size. It does not include personally identifiable information.

Survey After Viewing *optional*

After viewing the media, there is another opportunity to ask viewers’ questions. This screen is only displayed if one or more questions are defined by the study creator.

Viewing Complete [or REDIRECT]

This screen is shown after the viewing process has completed and all data has been received. If the viewer arrived from a third-party panel, they will be automatically redirected back to the original survey system at this point and will not see this screen.
