Pupil Cloud UI Overhaul

Since the first release of Pupil Cloud in 2019 (time flies!), we have received a lot of feedback from the community and gained tons of experience using it ourselves. This led us to rethink the entire UI and do a major overhaul, which is now ready for release.

The new UI is available starting today at cloud.pupil-labs.com and we encourage you to check it out! In case you are not ready to make the switch yet, you can still access the old Pupil Cloud UI at old.cloud.pupil-labs.com.

We compiled a shortlist of the most important changes and the motivation behind them below. If you'd prefer a short video introduction check out our new onboarding video!

There are some significant changes, and we would love to hear what you think about them! If you have any feedback or feature requests, please let us know. If you have any issues or questions, reach out via via chat!

Navigation

The new navigation bar lets you move between workspaces and projects faster and easier. The breadcrumb structure keeps you informed of your current location.

Project Editor

We have completely redesigned the project and enrichment interaction. In the old design, there was a lot of back-and-forth between different views. With this update we aim to provide a streamlined pipeline.

Enrichment View

The new Enrichment View lets you see everything about your enrichment in one place, including its definition and visualizations of the results.

Downloads

We have added a new Downloads View to projects, which enables you to download all recording and enrichment data from a single place. The overview now includes a summary of the files that will be included in each download. In a future update, you will also be able to customize which files you wish to download.

Global Events

We are making changes to how events work to create more consistency. Previously, there were two types of events in Pupil Cloud:

• Recording events: These events were created at recording time and uploaded to Pupil Cloud with the recording. They were then available in all projects to which the recording was added.
• Project events: These events were created post hoc as part of a project and were only available within that project.

This system was confusing because events did not behave consistently. It also meant additional work for many users, as they had to define the same events repeatedly if they used the same recording in multiple projects.

With this update, we are introducing Global Events. Every event, no matter when or where it was created, will always be available with the respective recording. This allows you to define an event once and use it in every project.

As part of this change, we are promoting all existing events to global events. Users who previously defined the same event multiple times in different projects will now see duplicate events in their projects. We apologize for any inconvenience caused.

Customizing and Filtering Recording Tables

We added Filters to make it even easier to find recordings in your workspace. You can use filters together with search. Filter based on attributes like wearer, duration, or any other recording attribute. Furthermore, you can now customize the columns displayed in the recording table. This means you can add columns that are important to you and remove those that are less relevant.

Hotkeys

We have introduced several new hotkeys to help power users move more quickly. To view the hotkey overview, access the help menu in the top-right corner of the screen.

These hotkeys will enable you to move more swiftly through recordings and speed up the event annotation process. If there are any additional hotkeys you would like to see implemented let us know.

Resizable Panels

The panels in the new user interface are resizable. You can choose what you want to see most of: the recording table, the player, or the timeline!

Templates and Wearers in Workspace Settings

All functionality to create, edit and delete Templates and Wearers has been moved to the workspace settings.

Big updates for Pupil Cloud! A Demo Workspace with sample recordings, projects, and enrichments for everyone to explore. Fixation scanpaths can now visualized in all video playback in Cloud.

Demo Workspace

Every Pupil Cloud user now has access to our new Demo Workspace. It contains recordings and an example project with enrichments. We encourage everyone to explore it to help understand cloud features, best practices, and to get hands-on on with a real world dataset recorded with Pupil Invisible. We will continue to add more projects over time. Have a use-case you'd like to see as a demo? Get in touch!

Learn more about the demo workspace here.

Fixation Scanpath Visualization

We have added a new visualization for fixation scanpaths to all video playback in Pupil Cloud. It shows the sequence of fixations for the last two seconds in a recording. The visualization compensates for head movements to ensure fixations remain in the right location even when the viewpoint changes. (We've got a white paper on the new fixation detection algorithm coming soon - stay tuned!)

We are excited to announce our latest update for Pupil Cloud including a new blink detector for Pupil Invisible, visualizations for the Reference Image Mapper enrichment and quicker access to data downloads in convenient formats!

Blink Detector

We built a brand new blink detection algorithm and are making it available in Pupil Cloud. Blinks will be calculated for recordings automatically on upload to Pupil Cloud and be available in exports. The algorithm analyzes motion patterns in the eye videos to robustly detect blink events including blink duration. We are planning on open sourcing the blink detection algorithm in the near future.

Learn more about the algorithm here.

Reference Image Mapper Visualizations

The Reference Image Mapper enables you to automatically map gaze from the scene video onto a reference image. We want to give users a glimpse into how the algorithm works and a way to inspect the results.

To facilitate that, we added two new visualizations for the Reference Image Mapper to the project editor.

If you select a Reference Image Mapper enrichment in the project editor sidebar you can enable a side-by-side view of the reference image and the scene video. You can play back gaze on them simultaneously and verify the correctness of the mapping.

Internally, the Reference Image Mapper is generating a 3D point cloud representation of the recorded environment. You can now enable a visualization of this point cloud projected onto the scene video. This allows you to verify that the 3D scene camera motion has been estimated correctly.

CSV Data Downloads In Drive

You can already use the Raw Data Exporter enrichment to download recordings in convenient formats like CSV and MP4 files. Now you can download recordings in convenient formats directly from Drive! We did this to help speed up the exploration of data for those who don’t need to create a project.

In the Drive view you can click on the Download button and now see two options. Download binary recording data which downloads the raw data as recorded on the Companion Device (plus 200Hz gaze data). And the new option called Download Recording which will result in CSV data files and videos in convenient formats (including 200 Hz gaze, fixation and blink data).

We are excited to announce our latest release for Pupil Cloud including a novel fixation detector, advanced privacy features in workspaces, and more! All recordings uploaded after this release will automatically have fixation data.

Fixation Detection

We have developed a novel fixation detector for Pupil Invisible! It was designed to cope with the challenges of head-mounted eye tracking and is one of the most robust algorithms out there!

Traditional fixation detection algorithms are designed for stationary settings which assume minimal head movement. Our algorithm actively compensates for head movements and can detect fixations more reliably in dynamic scenarios. This includes robustness to vestibulo–ocular reflex (VOR) movements.

Fixations will be calculated automatically on upload to Pupil Cloud and be available in all exports. We are planning on open sourcing our new fixation detection algorithm in the near future along with a white paper and integration into Pupil Player for offline support.

Check out documentation on fixations exported for enrichments in the docs

Advanced Workspace Privacy Settings

We are introducing additional privacy settings for workspaces to cover a few specialized use cases that were requested by the community.

You can now disable scene video upload for the entire workspace. This allows users to make use of Pupil Cloud features like the calculation of 200 Hz gaze or fixations, while complying with strict privacy policies that would not allow scene video uploads to our servers.

In a future release we will introduce the ability to automatically blur faces on-upload of a recording to a workspace, such that the potentially sensitive original version is never stored in Pupil Cloud.

“Created by” Column in Recordings List

You can now see who uploaded each recording in the Drive view “Created by” column. We hope this makes collaboration easier within your workspace.

Optimized Project Editor Layout

We made more space for the video player at the center, and added a toolbar above the video player. The toolbar contains contextual enrichment related functions. Currently only for the Marker Mapper enrichment - more in the near future!

Big release! We added two powerful new features. Workspaces enable collaboration with your colleagues. Face Mapper automatically detects faces in recordings!

Workspaces

Workspaces enable you to collaborate with colleagues through role based access from data collection with Pupil Invisible Companion App to data annotation and enrichment in Pupil Cloud. Workspaces act as isolated spaces that contain recordings, wearers, templates, labels, projects and enrichments.

Note: Update the Pupil Invisible Companion app to the most recent version (v1.3.0) to make use of workspaces.

Face Mapper

Face Mapper is a new enrichment that automatically and robustly detects faces in the scene video and maps gaze data onto the detected faces. This enables you to easily determine when a subject has been looking at a face and to compute aggregate statistics (example: how much time was spent looking at faces?).
