MPS Updates

Once you upload data using the MPS CLI, it will be stored for 30 days for additional processing/reprocessing, instead of 24 hours.

New Hand Tracking MPS, Wrist and Palm Tracking

For this new service, we use Aria's SLAM camera images to estimate the hand movements of the wearer. The wrist and palm poses are given in the device frame in meters. These outputs are automatically generated when doing the default MPS CLI request (or request hand_tracking mode) and are listed as Hand Tracking in the Desktop App.

Install Project Aria Tools vs 1.5 using Pip or install Desktop App v38 to be able to request this new service.

Update to Eye Gaze outputs - depth estimations

We have introduced a new model for computing eye gaze, which produces left and right eye gaze directions along with the depth at which these gaze directions intersect.

This new model’s output schema adds to general_eye_gaze.csv and personalized_eye_gaze.csv in a way that ensures backward compatibility with Project Aria Tools.

Known Issues

  • The new Eye Gaze model does not generate yaw_rads_cpf outputs
    • This value can be computed using helper functions and is automatically read when parsed with our data utilities.

Bug Fixes

Minor bug fixes

Desktop Companion App v38

Download v38 on Windows or MacOS to request Hand Tracking MPS and to get bug fixes.

MPS requests using the Desktop app have been slightly restructured, you no longer need to request Point Cloud data as an additional service. The request options are:

  • SLAM (6DoF Trajectory, Semi-Dense Point Cloud, Online Sensor Calibration)
  • Eye Gaze (General, plus personalized if the VRS file contains In-Session Eye Gaze Calibration)
  • Hand Tracking (Wrist and Palm Tracking)

The Streaming button in the dashboard has been renamed to Preview, to better reflect the capability provided by the Desktop app. Use the Client SDK with CLI to stream data.

Desktop app logs are now stored in ~/.aria/logs/ariadesktop_app{date}_{time}.log

  • Please note, the streaming preview available through the Desktop app is optimized for Profile 12.

Known Issues

  • If you encounter the file too small error when requesting MPS, it may be because the Desktop app is in a bad state. Restarting the app should resolve this issue
  • Selecting Cancel does not work when downloading MPS is in progress
  • [MacOS] When the app is launched with logging enabled, the Aria icon might not appear in the taskbar, but functions should not be impacted
  • [Windows] The Aria icon does not render correctly when pinned to the taskbar

Bug Fixes

  • If starting recording/streaming fails the UI will now refresh
  • Issue where you can’t request MPS unless you interact with tick boxes has been resolved
  • Issue where the Desktop app did not quit completely on MacOS has been resolved

Project Aria Tools v1.5

Project Aria Tools provides open tooling for anyone wanting to work with Aria data. For this release it enables users to request Hand Tracking data using the MPS CLI and provides a new ASR Python code sample.

Update Project Aria Tools:

Go to https://github.com/facebookresearch/projectaria_tools/releases/tag/1.5.0 for the full release log.

Speech to Text Code Sample (Python)

This new ASR Python code sample shows how to use Faster Whisper to run Whisper Speech Recognition on an Aria audio stream. The ASR outputs are time aligned with Aria Device Time.

Go to the Automated Speech Recognition Readme for how to get started.

Speech to Text outputs

Aria Glasses OS

The latest Project Aria OS build 4968297.250.70 was released on March 11, 2024.

New recording profiles

We’ve released the following experimental recording profiles. If you use a new profile, we’d love to hear about how it works for you.

Recording Profile 26: Minimal sensors, low RGB frame rate for extended recording times. The aim is 5+ recording hours while having RGB camera data at a low frame rate (unlike Recording Profile 20, which has IMU, but no RGB data).

Recording Profile 27: Designed for streaming over USB.

Recording Profile 28: Very high Eye Tracking camera frame rate.

Recording Profile 29: Low RGB frame rate, JPEG with decimation. This recording profile is the same as Profile 26, however 9 out of every 10 JPEG frames are skipped (decimation/sub-sampling). This is our first recording profile that uses decimation. The data from the RGB data stream is saved at a rate that archives a frame rate of 0.1FPS. The aim of this profile is to be able to record for 15+ hours.

Update to the latest version of the OS to access these profiles. Your glasses’ OS should automatically update when connected to Wi-Fi and power. Go to Updating OS to manually trigger an update.

You can see more details about recording profiles in the Mobile Companion app:

  1. Open the Mobile Companion App and select New Recording Session
  2. Select the existing recording profile (or Choose Profile if you have not set a default recording profile)
  3. Tap More Info in the top right corner
    • The More info link may be difficult to see, this will be fixed in a future version of the Mobile Companion app

Or go to Recording Profiles documentation in Project Aria Tools.

Known Issues

  • The new recording profiles are experimental and may be tuned further in the future.

Bug Fixes

  • Make sure your glasses’ OS is less than 2 months old, to make sure you have a fix for an issue that may cause sluggish behavior in your Aria glasses, difficulties updating the OS, streaming data and reduced upload times.
    • Updating OS includes troubleshooting steps if you have difficulties updating the OS.

Mobile Companion App v155

Please keep in mind, you can’t initiate recordings through the Mobile app if your glasses’ OS is more than 2 months old. Please make sure you update your glasses’ OS.

Updated look and feel of the Mobile app

The Mobile Companion app has a fresh new look! As part of this:

  • The Settings tab has been renamed Profile
  • Device Settings can be opened by tapping the glasses icon under Paired Glasses
Device Settings page from the Dashboard

Known Issues

  • The More info link on the top right of the Recording Profiles page may be difficult to see.

August Release - Project Aria Mobile App v125 is now available

8/22/2023

Dear Academic Partners,

Download the Aria Mobile App v125 to ensure you have all the latest features and capabilities.  Sign into the Aria Web Portal on your Android device to download v125.

NEW & UPDATED FEATURES

  • Ability to name VRS files via the Mobile Companion app
  • The default recording profile (if set via Mobile or Desktop app) will now also be the default profile when initiating recordings via the Mobile app
  • Added a feature that requires the app to be updated if the app build is flagged as severely buggy.

Ability to name VRS files

Historically, the VRS files were given random alphanumeric names. This made the recordings difficult to distinguish from one another in the Desktop app and after downloading them. With this new release, the name given to a recording when creating a custom recording defines the VRS file name. You’ll get a warning if there are two recordings with the same name on your Aria device.

To access this feature:

  1. In the mobile app, go to Settings to check that you have v125
    1. Sign into portal.projectaria.com on your phone to get the latest recommended build
  2. Go to device settings (select the gear icon next to your glasses) to check that you have 4963656.310.70 of the OS
    1. Aria glasses will automatically update if they’re connected to Wi-Fi and power
    2. Select Check for Updates in Device Settings to make sure you have the most recent version of the OS

How to name a recording:

Set the recording’s name when you create a custom recording, or edit the file name of any recording on your glasses. To edit the name or to give an existing recording a name:

  1. Go to the recording tab
  2. Select a recording
  3. Select Edit on the top right corner

Default recording profile applied to new recordings

With this change, the default recording profile selected for the glasses also applies to each recording started from the app. Previously, the default recording profile only applied to recordings started by the capture button on the glasses.

Please double-check that the correct profile is selected before you start each recording, as the behavior has changed. Previously, the app kept its own last-used setting; with this change, the default will flip back to the default recording profile of the glasses on connection. This default recording profile can be updated via Device Settings in the mobile app.

Disable severely buggy builds

This feature is a contingency plan, in case a severely broken app build is rolled out by mistake. In this situation, the app would show a full-screen dialog that requires it to be updated in order to proceed.

BUG FIXES

Various bug fixes implemented to improve the overall usage of the App.

PROJECT ARIA LATEST OS

The latest Project Aria OS build 4963656.310.70 was released on August 22, 2023.

Aria Mobile App v115 is now available

Dear Academic Partners, The Aria Mobile App v115 for Android is now available for download from the Aria Web Portal (accessed via your Android internet browser).

NEW & UPDATED FEATURES

  • Sensor data quality signals
  • In-Session personalized eye gaze calibration
  • Differentiate paired glasses in the pairing screen
    • When you select Add glasses, the available Aria devices will be split into Paired Glasses and Other Glasses so that it’s easy to tell which glasses are already paired with the app.

Sensor Data Quality Signals

While making recordings, researchers will be able to see whether there are any sensor data quality issues (for example, due to thermal mitigation). To check for any issues, in the Mobile Companion app, view the "Sensor Status" section in the Recording Status Screen. Tap on the row to see full details. If you’ve initiated recording via the Capture button, access the Recording Status by selecting Recording in progress on the Mobile Companion app’s main dashboard.

In-Session Personalized Eye Gaze Calibration

Users will be able to record personalized eye gaze calibrations within an ongoing recording. The eye gaze calibration section of the sequence can be used to improve the eye gaze estimations in the rest of the recording. In the future, Machine Perception Services will be able to consume these recordings and output more accurate gaze information.

  1. In the Mobile Companion app, create a new recording using a profile that includes ET and RGB cameras (such as Profile 15 or 25)
  2. Once your recording has started, close the recording window
    • Select X on the top left of the screen
  3. Go to Device Settings (select the gear next to your glasses)
  4. Select Eye Tracking Calibration
  5. Confirm that you’d like to run the during the current recording session
  6. Follow the prompts to calibrate your glasses

Eye Gaze Calibration tips

Things to Avoid

❌ Do not wear a face covering during eye calibration.

❌ Choose an area with ample and even lighting; do not face a bright light, window or reflective surface.

❌ Do not set your phone screen brightness too high compared to your surroundings.

❌ Do not fully extend your arm(s) during eye calibration. Your elbows should be bent so that the phone is roughly 1 ft (30 cm) away from your face.

Helpful Tips

✅ The phone should be held straight in front of your face, so that you shouldn't look up or down to see the screen. Hold the phone plumb (90 degrees) vertically to the ground.

✅ The "Leveler" stage appears if the position of your phone isn't within specifications for the calibration process. Adjust the phone in front of you and its distance by bending your elbow until the smaller, black circle turns into a green disk with a check mark.

✅ Once the "Leveler" stage is successfully completed, do your best to keep your phone in exactly the same position throughout the full eye calibration process. If your phone is moved to a position no longer suited to calibrate your device, the app will return to the "Leveler" stage.

✅ The eye calibration stages 1 to 10 move your nose towards the direction indicated by the arrow. If you're only following the direction with your gaze without moving your head, the calibration stage will time out and fail. However, you make sure to keep your eyes fixed on the number within the dot the whole time.
