Set up devices and test stations for a project

Aim

To set up measurement devices and test stations.

Before you begin

The devices and test stations functionality depends on your user role:

• As an Administrator you can set up devices and test stations for any project.
• As a Researcher you can set up devices and test stations for projects you created yourself and for projects shared with you as a member.
• As a User you can set up devices and test stations for projects shared with you as a member.

Navigate to the project for which you want to set up the devices and test stations.

Note: Devices and signals are logically connected

A device and its signals are logically connected in NoldusHub. When you switch off a device, all its connected signals are also automatically switched off. And vice versa, when you switch off all signals for a device, the device itself is also switched off.

The same applies to switching on: When you switch on a device, all its signals are also switched on. So, for example, when you switch off an Eye tracker device, the Gaze signal is automatically switched off. Or the other way around: When you switch on a Screen video device, the Screen video signal is also switched on.

Procedure

1. If you want to set up a test station other than the first, click on the appropriate test station to collapse its details.
2. Switch on or switch off the signals and devices toggles to select or unselect them for your project. For example, switch on the Gaze signal and switch off the Screen video signal.

What's next?

You can calibrate an eye tracker for your project or jump right in to record a session.

Connect biosensor to Participant PC

Aim

To connect a biosensor to a Participant PC. See Supported devices for a list of our currently supported eye trackers, biosensors and webcam.

Calibrate eye tracker

Aim

To calibrate an eye tracker device to ensure recordings are as accurate as possible.

Before you begin

The calibrate functionality depends on your application-level user role:

• As an Administrator you can calibrate eye trackers for any project.
• As a Researcher you can calibrate eye trackers for projects you created yourself and projects shared with you as a member.
• As a User you can calibrate eye trackers for projects shared with you as a member.

Ask a colleague or co-worker to assist you as a participant because calibration is an interplay between a Test leader PC and the Participant PC.

Navigate to the record page of the test station inside your project for which you want to calibrate the eye tracker.

Note

Calibration starts from the Test leader PC. Each procedure step indicates who, you or the participant, must execute the step. Check the Frequently Asked Questions (FAQ), if you run into trouble.

Procedure

1. You: Ask the participant to take place at the Participant PC and to follow the instructions on the screen.
2. You: Click Record Session. NoldusHub asks whether you want to calibrate the eye tracker or skip the calibration and start recording. If you skip calibration, the calibration that was stored last will be used. In this case, click Calibrate. You can dismiss the notification for a certain amount of time. To bring back the notification click the notifications icon. A list appears of all dismissed notifications. Find the notification you want to bring back and click Cancel. OR Click the menu icon and select Calibrate in the Screen video pane. NoldusHub shows a Welcome screen for starting the calibration at the test station (Participant PC).
3. Participant: Follow the instructions that are shown on the screen of the Participant PC. They have to click on Start.
4. Participant: Once the calibration is finished, click Close. NoldusHub shows the Calibration results pop-up on the test leader PC.
5. You: If calibration succeeded, click ACCEPT. OR If calibration failed, click Recalibrate and repeat steps starting from step 3. Some tips on how to calibrate your eye tracker successfully can be found in the FAQ section.

What's next?

You can set up other users as members for your project or jump right in to record a session.

Select project members

Aim

To share your project with co-workers.

Background

User types

NoldusHub distinguishes application and project-level users. See User management for more information about the differences.

Project member roles and permissions

As the creator of the project, you are immediately assigned the Owner role. You can select users to add them as an Editor. If a user is not an administrator on the application level they will have to be invited as an Editor in order to see the project. The rights of editors are equal to the rights of the owner.

• Owner: The project member has all project rights.
• Editor: The project member has all project rights.

Before you begin

The sharing project functionality depends on your application-level user role:

• As an Administrator you can select members for any project.
• As a Researcher you can select members for projects you created yourself and projects shared with you as a member.
• As a User you can select members for projects shared with you as a member.

The project member you want to select must already be available as an application-level user.

You need to determine what project member role the new project member needs.

Navigate to the project for which you want to select members.

Procedure

Select member(s) for a project

1. Navigate to the members page by clicking Project members in the Setup section.
2. Click Share project.
3. To open the user list, click in the Choose members field.
4. Optional: To narrow down the list, enter the first characters of the username of the user you want to add.
5. Select the user you want to add to your project.
6. Optional: To add other members, repeat steps 3–5.
7. Click Save.
