I should add another setting for 'returning to default pose' animation to the customizable expression feature. That way you save another expression slot.

After this feature, facial expression recognition AI should be as easy as setting which expression slot you want to use for the AI result.

SilverStraw Wow, the tool can finally capture body movements!! That is definitely an inovative update 😃 I'm really looking forward to the day when it will be available!!

      @SilverStraw oh, a new MediaPipe model? That's super cool! Likely worth the time investment.

      I need your help breaking it the application again 🤣. This is using the new facing tracking. I haven't added any tracking smoothing and I am not sure if it is needed. You can tell me your thoughts.

      Hopefully I can transfer the body animation code to the new body tracking without much problem like the face animation. The draw order won't be ready with the body tracking because I haven't figure a good solution to handle depth for Spine skeletons.

          SilverStraw The new face tracking seems very fine! 😃 You mentioned you did not add any tracking smoothing, but it already seems very smooth. The following video is the result of testing on my end:

          It may be hard to tell from the video, but I feel that the movement has become less wobbly, and when I want to stop the movement, it can be stopped properly.

          I'm looking forward to body tracking becoming available! 💓

            2.0.1

            • Added a check box for enabling body pose tracking. It is located under "AI Settings" menu > "AI Tracking Modes" section > "Body Tracking".
            • Added a button for 3d plot graph showing body pose. It is named "Update 3D Plot" and is located under "Camera Settings" menu.

            https://silverstraw.itch.io/spine-vtuber-prototype-2

            Test model updated.
            https://silverstraw.itch.io/spine-vtube-test-model

              SilverStraw Awesome!! I tried it with your test model and it certainly did body tracking on my PC. It's absolutely fun to have the model on the screen react to my movements 😄 When I get a chance, I would like to modify my model for body tracking. Great job!! 🎉

                For people who don't have time to try it for yourself, I've recorded a screen video. This may be helpful for those who are having trouble understanding how to set it up:

                For your information, I was wearing a skirt when I recorded this, and I think that's why the tracking of my legs wasn't working very well.

                @Misaki I noticed that this body tracking works better when the whole body is within frame from my experience. It may not completely be your skirt's fault. If you have the chance could you test the body tracking wearing a skirt but have your foot within web camera frame. I think the body tracking would predict better results that way.

                The body tracking software makes more assumptive predictions, like when your legs and arms are not in frame.

                I might have the software check both if the knee and ankle are out of frame and prevent them from going swaying wildly. So far, the software checks those features individually.

                I mentioned this on Discord. The next tracking I should tackle is hand gesture since I think it's straightforward. Various hand gestures: closed fist, open palm, pointing up, thumbs down, thumbs up, victory sign, I❤️U sign. If the tracker detects any of the hand gestures with a high degree than swap out the hand components. I hope it is able to distinguish left and right hands.

                Just chiming in to say this is super cool! I should play with the new MediaPipe models one day as well and resurrect my vtubeing app 🙂

                2.0.2

                • Add a pointing downward behavior for the Spine model legs when the tracked legs are outside the video frame boundary. The leg positions are more assumptive and less reliable when outside of video frame boundary. The legs should default to pointing downward ( standing position ) to look more natural than flailing legs.
                • Start to implement web parallel processing for browsers that support it. Multiple threads might speed up computation tasks.
                • Defer 3d graph plotting task to optimize canvas rendering.
                • Save 3d plot graph camera location when user rotates the graph. Note that the user can only rotate the graph when the graph is not being updated ("Update 3D Plot" is unchecked).
                • Replace the word "body" with "torso" in the animation names of "body_rotate", "body_scale_y", and "body_scale_x". Make these animation names less ambiguous.

                Spine Vtuber Prototype 2.0.3

                • Added a check box for enabling hand tracking. It is located under "AI Settings" menu > "AI Tracking Modes" section > "Hand Tracking".
                • Added "Debug Bounding Boxes" checkbox under "Canvas Settings" menu. Axis aligned bounding box and bounding polygon have separate color and opacity settings. Bounding polygons would help visualize collision shapes.
                • Fixed a lag bug caused from turning on and off the camera/video. The software activated body tracking too frequently in a short amount of time. Mitigated by slowing down the activation from microseconds to milliseconds.

                https://silverstraw.itch.io/spine-vtuber-prototype-2

                Spine Vtuber Prototype 2.0.4
                Implemented hand gesture tracking to the application. Two hands closer to the goal.

                https://www.deviantart.com/silverstraw/art/Spine2D-Vtuber-Hand-Gesture-Test-974400292

                • Fixed "Showing Landmarks" canvas bug where it was not showing. The canvas was erasing faster than it can draw due to the 2.0.3 lag bug. Synchronized the erasing only when it is ready to draw the next frame.
                • Added hand gesture tracking for closed fist, point up, victory sign, I love you sign, thumbs up. thumbs down. Hands open is assumed to be the default hand position.

                  SilverStraw This is definitely AMAZING!! 😍 As soon as I have time, I would like to modify my model to support hand tracking and try it out.

                    I updated and grouped the Spine animation names. The grouping is necessary as this project has grown to include various optional tracking modes.

                    Spine Vtuber Prototype 2.0.5

                    • Optimized setting Spine animation for hand gestures only once. Prevent continuously setting Spine animation for the same hand gesture animation.

                    • Added background thread support for body tracking AI on supported modern web browsers. The background thread start up the AI immediately without hindering the main thread. Users would experience shorter or no wait after starting the body tracking for the first time.
