All software releases
Here you will find a log of all features, changes, bug fixes, and developer notes for Pupil Labs software.
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.
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!)
Gaze Super Speed!
We have drastically increased the framerate of the real-time gaze signal to 120+ Hz. This was made possible by the hard work of our R&D and engineering teams in optimizing the neural network that runs on the Companion Device. Accuracy remains with drastic improvements to inference speed!
The high speed gaze data is available both in the recording data as well as via the real-time API. As usual, the full 200 Hz signal is available after uploading to Pupil Cloud.
Pupil Invisible Monitor
Monitor your data collection straight from the web-browser - on any device!
pi.local:8080 into your address bar and the Pupil Invisible Monitor app will open, which allows you to view video and gaze data from all the Pupil Invisible Glasses in your network!
It also allows you to remote control them, see storage and battery levels, and save events with the press of a button.
A more detailed introduction can be found here.
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!
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).
Real-Time Network API and python library
Check out Pupil Invisible’s new real-time network API! This makes it easier than ever to get real-time eye tracking data for your research and applications.
Use our new Python library to instantly receive video and gaze data on your computer and remote control all your Pupil Invisible devices.
Implement gaze-interaction methodologies or track the progress of your data collection by starting recordings and saving events programmatically in no-time!
To learn more, please check out our Real-Time API Guides.
A new and improved version of Pupil Invisible Monitor based on this API is also coming very soon!
Pupil Invisible & Pupil Cloud Docs
Big update to the Pupil Invisible & Pupil Cloud docs. We improved the structure and added new tutorials and guides. Take a look!
