AWS Alexa Nursing Skill Workshop

A set of e-health workshops to apply AWS technologies for health improving. During this workshop we will show how to develop a Nursing Skill for Alexa to ask about your health data and store into DynamoDB tables.

The conversation will be like this:

You>> Open nursing skill
Alexa>> Welcome to Alexa Nursing Skill, please tell me your name
You>> My name is <>
Alexa>> Welcome <>, you can ask me about your health
You>> Blood Pressure Input
Alexa>> What is your sistolic pressure <>
My sistolic pressure is 115
Alexa>> What is your diastolic pressure <>
You>> My diastolic poressure is 75
Alexa>> Thanks <>

Introduction

You will learn how to build your own Alexa Skills that can be applied for e-health proposal by taking your health data. As example we provide a complete interaction to ask your name and also your blood pressure. But you will learn how to extend and create your own input interactions for:

Glucose
Emotional State
Weight
Blood Exam

1. Create Alexa "Nursing Skill" using pre-configured Lambda
2. Create your own Lambda Function for Nursing Skill
3. Create your own DynamoDB table
4. Customizing Nursing Skill

1.Create Alexa Nursing Skill

This first part you will learn how to create, configure and test a new Alexa Skill using a pre-existing Lambda function as back-end. After this step you will have your first Healthcare Skill working and then you can create your own Lambda function to customize or extend this skill to store different types of biometric data.

Step #1: Navigate to Alexa Developer Website

Step #2.1: Create your developer.amazon.com user

Step #2.2: Accept the license

Step #2.3: Click "Save and continue"

Step #2.4: Click "Alexa" menu

Step #3: Click "Getting Started" in Alexa Skills Kit

Step 4: Click "Add a new Skill"

Step #5: Configure Skill Information

Step #6: Click on "Launch Skill Builder"

Step #7: Copy configuration file and paste into code editor

Step #8: Click "Save Model" and then "Build Model"

Step #9: Wait until finish..

Step #10: Click "Configuration" to setup the Lambda Function

Step #11: We need to provide the Lambda Function ARN in Global Fields. ARN is the address of some existing Lambda function.

Step #12: Let's use our existing Lambda Function with this ARN. This ARN points to our Lambda in our account.

Step #13: Your skill configuration should be like this, click "Save" and "Next"

Step #14: Time to test! Click "Go to Test Simulator"

Step #15: Enable test for this skill

Step #16: Click and hold the Mic icon to start a conversation

You>> Open nursing skill
Alexa>> Welcome to Alexa Nursing Skill, please tell me your name
You>> My name is <>
Alexa>> Welcome <>, you can ask me about your health
You>> Blood Pressure Input
Alexa>> What is your sistolic pressure <>
My sistolic pressure is 115
Alexa>> What is your diastolic pressure <>
You>> My diastolic poressure is 75
Alexa>> Thanks <>

2.Create your own Lambda Function to your Alexa Skill

Now that we have our own skill using a pre-existing Lambda function that allows any skill to use it, you will learn how to create your own lambda function copying our code and then replace the Lambda ARN in your Alexa Nursing Skill.

Step #1: Create a new Lambda Function, click "Create Function"

Step #2: Choose "Author from scratch"

Name: NursingSkill
Runtime: NodeJS 6.10
Role: Custom Role
It will open IAM console to create the role

Step #3: Configure IAM role:

IAM Role: lambda_basic_execution
Policy Name: Create new Role Policy
Click Allow

Step #4: Configure the role in your function

Step #5: Add Alexa Skill Kit trigger

Step #6: Disable Skill ID verification

This way any skill can use trigger this Lambda. If you want to restrict you can pick you Alexa Nursing Skill ID and limit the execution for only one skill.

Step #7: Copy and paste into code editor

Step #8: Click "Save"

Step #9: Now you can copy your own Lambda ARN to the clipboard

Step #10: Open your Alexa Developer Console and click "Configuration"

Step #11: Paste the new Lambda ARN

Step #12: Before testing, we need to create your DynamoDB table!

3.Create your own DynamoDB table

To finish your Nursing Skill using youtr own Lambda Function you must create a DynamoDB table and make sure that Lambda Function has the right permissions.
