Overview

In this unplugged activity, students learn about voice assistant technology, and participate in part of the Design Thinking cycle by problem framing and ideating an Alexa Skill that solves a specific problem.

Introduction

Ask: What is “voice assistant” technology?
A: Technology that ‘assists’ or helps us, which we can interact with using our voice.

Voice assistants like Alexa use voice recognition, speech synthesis, and natural language processing (NLP) to understand what we are saying. The more time Alexa spends talking to people, the more information she can collect and learn from. (This is called machine learning!)

Voice assistants can help us with things like checking the weather, reading us recipes, and ordering pizza. When connected to smart-home devices, they can even change the temperature, turn off the lights, or make a cup of coffee!

Voice assistant technology is innovative because it uses technology in a new way to help solve problems. It can help with productivity, accessibility, organization, and more.

Why learn about Voice Assistants?

This is a growing technology with so many possibilities! We can use voice assistants as a tool to solve problems and make our world a better place for everyone. For example, using Alexa to support those impacted by Hurricane Florence.

How does Alexa work?

Alexa uses boolean logic: true or false. We can teach Alexa to do something IF a condition is true, or something else IF the condition is false. All of Alexa’s decisions are framed using these IF statements (or conditional statements).

Ask Alexa some questions to get a better idea of how she works:

  1. Open up the Echo Sim: https://echosim.io/ - You may need to grant permissions for the website to access your microphone. (or use a physical device, if you have one)
  2. Hold down the microphone icon and say, “Alexa…”
  3. Then ask her a question, such as:
    • “What is the weather today in Halifax?”
    • “Who invented the goalie mask?”
    • “What is Canada’s national animal?”

*Note: If the Echo Sim is not working, try restarting your computer and trying again, or skip to the main activity and try again later.

Activity

Alexa Skills are programs that teach Alexa how to do something. We are going to use creativity and innovative thinking to ideate an Alexa Skill that solves a specific problem.

Problem Framing

We first need to understand who is affected by a problem, and which challenges they are facing before trying to solve the problem.

Use the example Problem Framing worksheet (attached) to go through an example exercise together.

  1. On an anchor chart paper, write: “How might we encourage people to recycle more often?”
  2. Divide the paper into 4 parts with one the 4 C’s written in each corner (see worksheet)
  3. Using the example worksheet, explain what each word means, and work with the group to write 3-4 point in each section. Have the class guide what you are writing, but feel free to use the example points to facilitate discussion if learners need more guidance.
  4. Think-Pair-Share: "Based off of our findings, how could we use Alexa to solve this problem?" Remember: Our solution can be as wild as we like! Even if a feature doesn’t exist yet, that doesn’t mean it won’t be possible in the future. (Have learners write down ideas, share with a partner, then share their solutions with the class)
  5. Write down a possible solution shared in class at the bottom of the chart paper (try to combine ideas and decide on one solution as a class)
  6. How will this idea help solve our identified issues? What are some constraints?

Split learners into groups of 3-4. Each group will choose a new problem and work to complete a 4 C’s worksheet together. Write a few more examples on the board before groups begin.

Examples:
How might we…

  • Make studying more fun for students?
  • Help someone with memory loss stay on top of important tasks, like buying groceries, or paying bills?
  • Train students for new jobs, like babysitting for a new family?
  • Support independent living for individuals with acquired brain injuries?
  • Help students manage their time between school, clubs, and everything else?

Have groups share an overview of their worksheet with the class, including their proposed solution, how it solves their identified challenges, and any additional constraints or considerations.

Learning Outcomes

I can use technology as a problem-solving tool
I can use problem framing to try to understand the context of a problem
I can work with others to find creative solutions to problems
I can communicate with computers using tools like the Echo simulator

Provide time for learners to explore the “Amazon Alexa Skills Challenge: Tech for Good” submissions as inspiration for their own Alexa Skill idea: alexatechforgood.devpost.com/submissions

This is only part of the Design Thinking cycle. Continue using this awesome Design Thinking resource: bit.ly/DTOpen

Create working prototypes using Alexa Skill Blueprints: blueprints.amazon.com (parental permission required) - then test it out with the Echo Sim: echosim.io

Use the Echo Sim in an “Ask three, then me” model, where learners are encouraged to ask other students - or Alexa! - before asking the teacher a question.
