Making Amazon Alexa respond to Sign Language using AI

Latest project from Abhishek Singh utilizes Machine Learning and Computer Vision to enable Sign Language as an input to Smart Speaker technology:

If voice is the future of computing what about those who cannot speak or hear? I used deep learning with TensorFlow.js to make Amazon Echo respond to sign language. 

Real-time Human Pose Estimation in the Browser with TensorFlow.js

Machine Learning web demo from Google Creative Lab and Dan Oved can detect human poses via a webcam with web code:

In collaboration with Google Creative Lab, I’m excited to announce the release of a TensorFlow.js version of PoseNet¹,² a machine learning model which allows for real-time human pose estimation in the browser.

So what is pose estimation anyway? Pose estimation refers to computer vision techniques that detect human figures in images and video, so that one could determine, for example, where someone’s elbow shows up in an image. To be clear, this technology is not recognizing who is in an image — there is no personal identifiable information associated to pose detection. The algorithm is simply estimating where key body joints are.

Ok, and why is this exciting to begin with? Pose estimation has many uses, from interactive installations that react to the body to augmented reality, animation, fitness uses, and more. We hope the accessibility of this model inspires more developers and makers to experiment and apply pose detection to their own unique projects. While many alternate pose detection systems have been open-sourced, all require specialized hardware and/or cameras, as well as quite a bit of system setup. With PoseNet running on TensorFlow.js anyone with a decent webcam-equipped desktop or phone can experience this technology right from within a web browser. And since we’ve open sourced the model, Javascript developers can tinker and use this technology with just a few lines of code. What’s more, this can actually help preserve user privacy. Since PoseNet on TensorFlow.js runs in the browser, no pose data ever leaves a user’s computer.
