The idea behind this application is to have a way to check pulse rates with the most available devices, mobile phones. Here's a brief description of the code pattern:

• Create a classification model using a dataset which contains the pulse data and its related derived values. Deploy the model and expose it as Watson Machine Learning endpoints
• Register the mobile device with Watson IoT Platform
• Using the mobile app, generate the LIVE pulse data. This data is published to IoT platform and then stored in a NoSQL database
• Streaming the pulse data from the app in real-time (or the database) and using Watson Machine Learning validate it with the deployed model

• Step 1 - Node.js application
• Step 2 - Watson IoT Platform Service & Cloudant Database Service
• Step 3 - Watson Machine Learning
• Step 4 - IBM Watson Studios

• After doing the above steps, try it on your mobile phone's browser: http://<YOUR_APP_NAME>.mybluemix.net

  You can try our demo app at http://mypulse.mybluemix.net/ to have an idea how it looks. Note that if the machine learning service is over quota is will show undefined for some fields.

• Open Watson IoT Platform Quickstart
• Put your Device ID (found on your mobile app) on there for real-time streaming view of your data.

• IBM Watson Studio
• Introduction to Watson Studio
• IBM Cloud
• IBM Cloud Documentation
• IBM Cloud Developers Community
• IBM Watson Internet of Things
