Release December 20th 2022

Third December 2022 Release

Breaking Changes: None.

Changed: Motion Analysis Service, Java Client, Swift Client, Exercises.

Motion Analysis Service - 1.32.0

Improved Error Handling

The error handling behavior has fundamentally been reworked and the coverage of error cases that are now reported to the API user has been increased. This covers errors that happen on the server side, connection interruptions, timeouts and invalid inputs among many others.

What changes concretely for the API user:

Many more error cases are covered, the exact list can be found in the client documentation (Java and Swift).
A new error type was added that reports when an invalid API key was submitted.
The session is stopped when an error occurs.

What you must do: Nothing.

What you should do: Check out the new error types and see if your internal error handling and if dependent features like reconnection could benefit from it. We are looking forward to receiving your feedback!

Java Client and Swift Client - 1.8.0

Key features:

Implements the improved error handling described above.
Language specific implementation details can be found in the changelogs for Java and Swift.

Breaking Changes: Java and Swift Client will have a changed Enum, requiring you to adapt when updating to the new clients.

Changed: Java Client, Swift Client

Java Client - 1.6.0, Swift Client - 1.5.0

Key features:

Improvements in the Session Quality
More documentation

Session Quality

The Session Quality received an overhaul:

The middle category was renamed from poor to ok, leading to the three categories bad - ok - good. Note that this change requires you to adapt your code when updating to the newest version.
We added a new category none, which is present in the beginning, when we are not yet able to give a good estimate about the quality. This should take a couple of seconds.
Improved our estimation and increased the stability.

We created detailed information for Java, respectively Swift.

Important Note: While we managed to determine an adequate estimate how the latency affects our motion analysis, the environment quality must be viewed with caution. We didn’t yet find the exact relation between the environment and our systems performance, which is why the environment quality should be considered as auxiliary information.

Documentation

Next to more detailed explanation about Session Quality, we created a page about best practices and refined the requirements regarding the image input (Java and Swift). This is part of a greater initiative to provide you with more guidelines for a successful application.

What you must do: Nothing.

What you should do: Check out the new documentation and session quality and let us know if it fulfills your needs.

Motion Analysis Service - 1.21.0

Unilateral exercises

For unilateral exercises, that are not further specified with left or right, the Movement Analyser allows repetitions being counted for both sides. Consider for example the hip abduction exercise, where one can do repetitions abducting the right or left leg with corresponding form feedback.

The feedback is the same for both sides, however the metric (specifying what is measured) not. Taking hip abduction again as an example: Feedback “Lift your leg higher” with key 106 can either be based on the right or left leg abduction. So far, we always returned the same metric, usually the right one. With this release we are fixing that. If the user did a hip abduction with the left leg, you continue receiving the same feedback message and feedback key, but the metric will now point to the correct definition, the left hip abduction angle metric.

Please find both metric keys in the developer zone for the corresponding exercise and reach out if you have any questions.

Motion Analysis Service - 1.20.0

Activity Event

The generic ActivityEvent is introduced to provide feedback for a wider spectrum of the user’s motion, towards our goal to seamlessly track the user’s motion and understand their intent. It contains the known and unchanged Repetition as well as the newly introduced Attempt:

Attempt: The exercise was performed but the range of motion or form is far from the target exercise that it is not considered a repetition but only an attempt. We provide a feedback so that the user feels recognized and a guidance how to reach a full repetition.
Repetition: The exercise was completed with a range of motion that is large enough to be considered a repetition. However, there can still be feedback for improvements if the user does not reach the optimal range of motion. Note that it is the same object and behavior as in the RepetitionEvent.

Detailed information and examples on how to implement the new activity can be found in the respective API documentation:

Java-Client

Swift-Client

What you must do: Nothing. The behavior of the existing RepetitionEvent has not changed.

What you should do: Check out the new ActivityEvent and see if your product could benefit from it. We are looking forward to receiving your feedback!

Java Client 1.5.0 and Swift Client 1.4.0

Key features:

Add the aforementioned ActivityEvent to the API. For more details see the changelogs for Java and Swift

Authentication

For a more secure connection, API Key authentication is required to access our service from now on. Un-authenticated requests are blocked on the new host.

What you must do: Use your authentication key, we now block unauthenticated requests!

Motion Analysis Service - 1.13.0

Key features:

The visibility measures for sideways exercises have been optimized to avoid false feedback that the user is not visible and ensure that he or she reaches the EXERCISING session state.
A unique session identifier is created for each session and passed to the API user through the metadata response.
All body point types that are checked regarding visibility are provided to the API user. If these points change during the exercise, the relevant body point types are dynamically updated. Hence the API user can reconstruct what particular body point type caused the user to be considered as not fully visible.

VAY Unified Protocol (VUP) - 1.7.1

Key features:

A new session identifier is provided with the metadata response. Compared to the old session identifier, we ensure that the new identifier is unique.
All relevant body point types are provided with the metadata response when the exercise is configured. This field describes which body points are relevant for this exercise, i.e. must be visible in the frame. However, for specific exercises the relevant points can dynamically change while exercising. For example, in a sideways exercise if the user turns to the left or the right side different points are relevant. In this case, the updated relevant body points are provided in the image message.

Java Client - 1.2.0 and Swift Client - 1.1.0

Key features:

To ensure that all body points that are relevant for the exercise are visible, a collection of these body points provided. This allows the API user to inform the user which body part might still be hidden or not in frame. Additionally, the last estimated pose is available.
For each session a unique session identifier is provided.
Offer the option to pass a timestamp of the image capture time when enqueuing an image to the Analyser. We strongly recommend to set this parameter for better performance.
Enable the option to pass a user name when creating the Analyser.

Package updates:

Updated to VUP 1.7.1
Updated package swift-nio-http2 in Swift client to 1.19.2 for security reasons.

For more details see the changelog for Java and Swift.

Motion Analysis Service

Session State The session states are introduced, which describe in which exercise stage/state the user is in. There are three different states:

NOHUMAN: When the user is not visible in the field-of-view of the camera.

POSITIONING: The user is visible, but has not assumed the required exercising position. Guidance helps the user reach the starting position in order to begin/resume exercising.

EXERCISING: During execution of the exercise. In this state, repetitions are tracked and form feedback is given. Note, that if the user is not fully visible anymore or not oriented correctly, the state will drop back into positioning. In either case, appropriate feedback will guide the user back into the starting position.

Detailed information about the session states can be found in the documentation of these projects:

What you must do: Nothing.

What you should do: Test the new guided user positioning, including re-positioning during the exercise and see if it could benefit your product. We are happy to receive your feedback!
