Tushar Chugh is a graduate student at the Robotics Institute at Carnegie Mellon University (CMU). There he studies the latest in robotics, particularly how computer vision devices perceive the world around them.

One of his favorite projects was a robot named Andy. Besides having arms, Andy could discern colors and understand spatial arrangement. Andy could also respond to voice commands, like “pick up the red block and place it on top of the blue block.” Andy’s speech recognition, a CMU framework, was about to change.

When Amazon came to give some lectures at CMU, they had a raffle drawing. Chugh won the drawing and took home a new Amazon Echo as a prize. Over three days and nights without sleep, he completely integrated Andy and Alexa using the Alexa Skills Kit (ASK).

When he saw Hackster’s 2016 Internet of Voice challenge, he knew he had to enter. And in August 2016, Chugh’s Smart Cap won the prize for the Best Alexa Skills Kit with Raspberry Pi category.

The inspiration and genesis of Smart Cap

According to Chugh, there are about 285 million visually-impaired people in the world. In 2012, he worked on a project to help the visually impaired navigate inside a building. His device, a belt with embedded sensing tiles, won a couple of prizes, including a Wall Street Journal Technology Innovation Award. It was ahead of its time, though, and it wasn’t yet practical to develop the technology into a commercial product.

A lot can change in four years, including Chugh’s discovery of Alexa. Besides dabbling with Alexa and Andy the robot, he has also worked with Microsoft Cognitive Services for image recognition. Chugh now saw a chance to bring a new and better “seeing device” to light.

“When I saw Alexa, I thought we can extend it and integrate [Alexa] as a separate component,” says Chugh. “I talked with a couple of organizations for the blind in India, and they agreed this kind of system would be very, very useful. That was my main motivation.”

Chugh says the hardware for the Smart Cap is basic. He used a Raspberry Pi (RPi), a battery pack, a camera and a cap on which to mount it. As for the software, it included:

  • Alexa Skills Kit (ASK)
  • Amazon Web Services (AWS)
  • DynamoDB
  • Microsoft Cognitive Services (MSCS)
  • Custom Python code to run RPi to interface with the camera and MSCS

The goal was straightforward. A visually-impaired user could ask Alexa what is in front of them. Alexa would vocalize the scene, allowing the person to navigate safely wherever he or she may be.

How the Smart Cap works

How do the pieces all fit together?

Chugh says there are two distinct parts.

First, the image capture and analysis:

  • As the Smart Cap wearer walks down the street, a Python script on the RPi directs the camera to take pictures every two seconds.
  • Another program sends the image to MSCS using RPi’s WiFi / phone connection.
  • MSCS returns a text description of the image with relevant keywords.
  • The description is stored on RPi, then sent via AWS to be stored on DynamoDB.

Now comes the Alexa skill:

  • The wearer says “Alexa, ask Smart Cap to describe the scene” or “Alexa, ask Smart Cap what is in front of me”.
  • The skill uses AWS Lambda to retrieve and parse the latest value from DynamoDB.
  • Alexa responds with the description and keywords via the speaker or bone conduction headphones.

In early 2014, Mandy Chan was attending a business conference when she discovered her true calling: emerging technology. A business analyst by training, Mandy started searching for a way she could break into the tech industry, to immerse herself in the technologies disrupting every industry. She researched online, frequented bookstores, and eventually decided to teach herself JavaScript programming.

Barely a year later, Mandy attended the Technica Hack ‘15—and won the JP Morgan Chase prize for best mobile app. For Mandy, that event started a new career. After participating alongside so many eager and helpful programmers, she knew what she wanted to do.

Just 11 months later, Mandy has won three more hackathons, including NY TechCrunch ‘16 and Manhattan AngelHack ’16. But unlike her first contest, all these prizes were for Alexa skills.

A hackathon skill helping users around the world

Mandy first discovered Amazon Echo while attending a 2016 developer conference in San Francisco. She watched a team working with an Echo, and it instantly appealed to her interests in both back-end software development and artificial intelligence. “It was like having my code right in front of me. I talked to my code, and the code kind of talked back to me,” says Mandy.

The day before TechCrunch New York in May, Mandy dove into all the online Alexa Skills Kit documentation she could find. The next day, nervous but determined, she created the prototype that became the Dr. Speech skill—and won the Best Use of Alexa prize.

Mandy, originally from Hong Kong, wanted to help others improve their pronunciation of challenging words, so she created a skill called Dr. Speech, which helps non-native English speakers pronounce words accurately, thereby giving them more confidence without expensive speech therapy sessions.

Mandy gets tweets from people around the world thanking her for how Dr. Speech has been instrumental in improving their pronunciation and has also inspired other developers to build self-improvement skills. Similarly, a user of Mood Journal—another of Mandy’s Alexa skills—wrote to say it helped him in battling anxiety and depression.

Humbled, Mandy repeats she loves to write software that helps people. “Every skill I write is an extension of me. Dr. Speech is about improving speech, because I strive to be a great speaker. I never imagined how my skills would have touched so many people.”

Magic mirror, on the wall—who is the fairest one of all?

Probably the most memorable line from Disney’s 1937 classic, Snow White and the Seven Dwarfs, it may soon become a household phrase again. Modern-day magic mirrors are taking a number of forms, from toys to high tech devices offering useful information to their masters. Now, Darian Johnson has taken that concept an enormous step farther.

Darian, a technology architect with Accenture, has worked in software solution design for 17 years. Today he helps clients move their on-premise IT infrastructure into the cloud. With a recent focus solely on Amazon Web Services (AWS), it’s only natural other Amazon technologies like Alexa would pique his interest.

One night, Darian was pondering what he might build for Hackster’s 2016 Internet of Voice Challenge. He was surfing the web, when he happened on an early concept of a Magic Mirror and realized he could do even better than that. He did. In August 2016, Darian’s new Mystic Mirror won a prize in the Best Alexa Voice Service with Raspberry Pi category.

A smarter mirror with the Alexa Voice Service

Darian says his morning routine consists of running between bedroom and bathroom, trying to get ready for work. He doesn’t have an Amazon Echo in either, but he does, however, have mirrors there. That’s another reason why an Alexa Voice Service (AVS)-enabled mirror made sense.

He set his budget at a mere $100. That covered a Raspberry Pi (RPi), a two-way mirror, a refurbished monitor and speaker, some wood planks and a few other assorted items. He determined that his device would:

  • Give the mirror-gazer access to all the skills available through Alexa
  • Provide unique visual capabilities in the mirror face via a custom Alexa skill
  • Display information only for a finite amount of time before it fades away (to make it mystical—and because Darian is light-sensitive when he sleeps)

You can build your own Mystic Mirror using the details on the Hackster site. But it was his software and Alexa that brought it to life.

Darian decided to voice-enable his Raspberry Pi, microphone and speaker with the Alexa Voice Service (AVS). That meant the Mystic Mirror’s master would have access to the built-in power of Alexa and over 4,000 third-party skills, developed using the Alexa Skills Kit (ASK). With just a word, they could control smart home devices, ask for a Lyft ride, play music from Amazon Prime accounts and much more. Best of all, since Alexa is getting smarter all the time, the mirror’s capabilities would constantly evolve, too.

Eric Olson and David Phillips, co-founders of 3PO-Labs, are both “champs” when it comes to building and testing Alexa skills. The two met while working together at a Seattle company in 2015. Finding they had common interests, they soon combined forces to “start building awesome things”—including Alexa skills and tools.

Eric, an official Alexa Champion, is primarily responsible for the Bot family of skills. These include CompliBot and InsultiBot (both co-written with David), as well as DiceBot and AstroBot. David created and maintains the Alexa Skills Kit (ASK) Responder. The two do most everything as a team, though, and together built the underlying framework for all their Alexa skills.

This fall, they’re unveiling prototyping and testing tools that will enable developers to build high-quality Alexa skills faster than ever.

In the beginning, there was ASK Responder

Eric and David first got involved with Alexa when Eric proposed an Amazon Echo project for a company hackathon. The two dove into online documentation and started experimenting—and having fun. “After the hackathon, we just kind of kept going,” Eric said. “We weren’t planning to get serious about it.”

But over the past year, they grew more involved with the Alexa community. They ended up creating tools that could benefit the whole community. “We wrote these tools to solve problems we ran into ourselves. We ended up sharing them with other people and they became popular,” David said.

The first of these, the Alexa Skills Kit Responder, grew from David’s attempt to speed the process of testing different card response formats. Testing a response until it was just right meant you had to repeatedly modify and re-deploy code each time you changed the response. Instead, this new tool lets developers test mock skill responses without writing or deploying a single line of code. Follow the documentation to set up an Alexa skill to interface with ASK Responder, then upload any response you’d like. The ASK Responder will return it when invoked.

And that’s just the beginning. The ASK Responder’s usefulness is about to explode.

A quantum leap for prototyping

David created Responder for testing mock responses. But the two soon discovered a home automation group using the tool in an unexpected way.

Instead of a skill called “Responder,” they’ll create a skill named My Home Temp, for example. They’ll map an intent like “What is the temperature?” and have their smart home device upload a response to the ASK Responder with the temperature of the house. When the user says “Alexa, ask My Home Temp what is the temperature?” Alexa plays the uploaded response through the Echo. This creates the seamless illusion of a fully operating skill.

Dave Grossman, chief creative officer at Earplay, says his wife is early-to-bed and early-to-rise. That’s not surprising when you have to keep up with an active two-year-old. After everyone else is off to bed, Grossman stays up to clean the kitchen and put the house in order. Such chores require your eyes and hands, they don’t engage the mind.

“You can’t watch a movie or read a book while doing these things,” says Grossman. “I needed something more while doing repetitious tasks like scrubbing dishes and folding clothes.”

He first turned to audio books and Podcasts to fill the void. Today, though, he’s found the voice interactivity of Alexa is a perfect fit. That’s also why he’s excited to be part of Earplay. With the new Earplay Alexa skill, you can enjoy Grossman’s latest masterpieces: Earplays. Earplays are interactive audio stories you interact with your voice. And they all feature voice acting and sound effects like those in an old-time radio drama.

The creation and creators of Earplay

Jonathon Myers, today Earplay’s CEO, co-founded Reactive Studio in 2013 with CTO Bruno Batarelo. The company pioneered the first interactive radio drama, complete with full cast recording, sound effects and music.

Myers started prototyping in a rather non-digital way. Armed with a bunch of plot options on note cards, he asked testers to respond to his prompts by voice. Myers played out scenes like a small, intimate live theater, rearranging the note cards per the users’ responses. When it was time to design the code, Myers says he’d already worked out many of the pitfalls inherent to branching story plots.

They took a digital prototype (dubbed Cygnus) to the 2013 Game Developers Conference in San Francisco. Attendees of the conference gave the idea a hearty thumbs-up, and the real work began, which led to a successful Kickstarter campaign and a subsequent release while showcasing at 2013 PAX Prime in Seattle.

Grossman later joined the team as head story creator, after a decade at Telltale Games. Grossman had designed interactive story experiences for years, including the enduring classic The Secret of Monkey Island at Lucas Arts. Most gamers credit him with creating the first video game to feature voice acting.

Together they re-branded the company as Earplay in 2015. “We were working in a brand new medium, interactive audio entertainment. We called our product Earplay, because you're playing out stories with your voice,” Myers says.

The team first produced stories—including Codename Cygnus—as separate standalone iOS and Android apps. They then decided to build a new singular user experience. That lets users access all their stories— past, present and future—within a single app.

When Alexa came along, she changed everything.

The making of an Alexa interactive storyteller

The rapid adoption of the Amazon Echo and growth of the Alexa skills library excited the Earplay team. The company shifted its direction from mobile-first to a home entertainment-first focus. “It was almost as though Amazon designed the hardware specifically for what we were doing.”

Though not a developer, Myers started tinkering with Alexa using the Java SDK. He dug into online documentation and examples and created a working prototype over a single weekend. The skill had just a few audio prompts and responses from existing Earplay content, but it worked. He credits the rapid development, testing and deployment to the Alexa Skills Kit (ASK) and AWS Lambda.

Over several weeks, Myers developed the Earplay menu system to suit the Alexa voice-control experience. By then, the code had diverged quite a bit from what they used on other services. “When I showed it to Bruno, it was like ‘Oh Lord, this looks ugly!’” As CTO, Bruno Batarelo is in charge of Earplay’s platform architecture.

An intense six-week period followed. Batarelo helped Myers port the Earplay mechanics and data structures so the new skill could handle the Earplay demo stories. On August 26, they launched Earplay, version 1.0.

Today’s guest post is from Joel Evans from Mobiquity, a professional services firm trusted by hundreds of leading brands to create compelling digital engagements for customers across all channels. Joel writes about how Mobiquity built a portable voice controlled drone for under $500 using Amazon Alexa.

As Mobiquity’s innovation evangelist, I regularly give presentations and tech sessions for clients and at tradeshows on emerging technology and how to integrate it into a company’s offerings. I usually show off live demos and videos of emerging tech during these presentations, and one video, in particular, features a flying drone controlled via Alexa. Obviously, a flying object commanded by voice is an attention getter, so this led me to thinking that maybe I could do a live demo of the drone actually flying.

While there have been a number of articles that detail how to build your own voice-controlled drone, the challenge remains the same: how do you make it mobile since most solutions require you to be tethered to a home network.

I posed the challenge of building a portable voice-controlled drone to our resident drone expert and head of architecture, Dom Profico. Dom has been playing with drones since they were called Unmanned Arial Vehicles (UAVs) and has a knack for making things talk to each other, even when they aren’t designed to do so.

Dom accepted my challenge and even upped the ante. He was convinced he could build the portable drone and accomplish the task for under $500. To make the magic happen, he chose to use a Raspberry Pi 2 as the main device, a Bebop Drone, and an Amazon Echo Dot.

Landon Borders, Director of Connected Devices at Big Ass Solutions, still chuckles when he tells customers how the company got its name. Founder Carey Smith started his company back in 1999, naming it HVLS Fan Company. Its mission was to produce a line of high-volume, low-speed (HVLS) industrial fans. HVLS Fan Company sold fans up to 24-feet in diameter for warehouses and fabrication mills.

“People would always say to him ‘Wow, that’s a big-ass fan.’ They wanted more information, but they never knew how to reach us,” says Borders. So the founder listed the company in the phone book twice, both as HVLS Fan Company and Big Ass Fans. Guess which phone rang more often? “In essence, our customers named the company.”

Today the parent company is Big Ass Solutions. It still owns Big Ass Fans. It also builds Big Ass Lights and Haiku Home, a line of smart residential lighting and fans. Now with an Alexa skill, the company’s customers can control their devices using only their voice.

Creating the world’s first smart fan

Haiku Home is where Alexa comes into the picture.

Big Ass Fans (BAF) is a direct-sales company. As such, it gets constant and direct feedback about customers' satisfaction and product applications. BAF found people were using its industrial-grade products in interesting commercial and home applications. It saw an exciting new opportunity. So in 2012, BAF purchased a unique motor technology, allowing it to create a sleek, low-profile residential fan.

That was just the starting point for BAF’s line of home products. The next year, BAF introduced Haiku with SenseME, the world’s first smart fan.

What’s a smart fan? Borders says it first has to have cutting-edge technology. Haiku Home fans include embedded motion, temperature and humidity sensors. A microprocessor uses that data to adjust the fan and light kits to the user's tastes. The device also has to be connected, so it includes a Wi-Fi radio.

The smart fan joins Alexa’s Smart Home

The microprocessor and Wi-Fi radio make the SenseME fan a true IoT device. Customers use a smartphone app to configure the fan’s set-it-and-go preferences. But after that, why should you need an app?

Borders remembers discussions in early 2015 centered on people getting tired of smartphone apps. Using apps were a good starting point, but the company found some users didn’t want to control their fan with their smartphone. BAF felt voice was definitely the user interface of the future. When they saw Amazon heavily investing in the technology, they knew what the next step would be.

They would let customers control their fans and lights simply by talking to Alexa.
