Words from Our Designers

Creating NOMAD for you

The builders behind NOMAD — Jason, Sam and Carmen

Remember the excitement you had when learning something new when you were young? We gradually lose this feeling when we learn through traditional methods, which either exert heavy pressure on how we absorb knowledge, or come with high barriers that deter us from learning something new. Learning should be fun, inspiring, exciting and accessible for everyone, and we hope Nomad can help every learner to bring that feeling back.

This is why we hold empathising real users’ needs to such high regard throughout the design and discussion process. We want them to embrace the idea that they can learn anything in the best possible experience through Nomad, regardless of their education background or learning style. Therefore, in between balancing how to adequately showcase Nomad’s exceptional features, we also had to make sure we were not neglecting the needs of our end users, ensuring that they are supported by an easily navigable user flow in their journey of stepping outside their comfort zone.

Paving Way for Bigger Stage in MIT Boston App Inventor 2019

Young coder is making a final touch before “Show & Tell” at Scratch Day 2019 in Tokyo

Preface Nomad was honored to be invited to Scratch Day Japan, the biggest coding event in Asia to present our students’ work to an international crowd. Coding teachers, Scratch coders and technology enthusiasts all gathered around the high stage while we presented “Let Snorlax Sleep, a game coded by our 6-year-old student. Is it just another game using a keyboard to play? 100% not. “Awesome” is the word to describe this game, as it cleverly uses the camera sensor to detect the gamer’s movement as the main control. Gamers can sweep the bugs off by swiping their hands in front of the camera, immersing in a 3D gaming experience. The applause and positive feedback from the audience reassured us the impact that Preface Nomad is making — we are not only showing our students how to make a game. We are empowering them to do something great, and become someone who owns the stage.

Originally published on MIT App Inventor official blog on April 22, 2019.


This is a guest blog by MIT Master Trainer Queena Ling.

Like many budding psychology students, Suki has a strong desire to aid those with special needs or suffering from mental health problems. Unlike her fellow psychology students however, Suki has taken her aspirations to the next level with her new mobile application – a mental health application built through App Inventor that aims at helping people combat depression.

Aided by a fundamentally sound coding skillset learnt through Preface NOMAD, the pioneer coding school in Hong Kong powered by A.I. technology in teaching, Suki has created a fully functional health application complete with an impressive range of features, including music to calm users and use of the web browser component to host web articles to motivate users, and educate them on how to overcome depression. A high school student with ambitions to study psychology at UCLA, Suki wishes to she can positively impact the mental health community in spite of her young age.

Suki hopes that adults and teenagers alike can find the perfect tool that they can draw strength from through her application, and hopefully empower them in their fight against depression.

Hacking School System with App Inventor at Preface

Originally published at MIT App Inventor Official Blog on April 22, 2019


This is a guest blog by MIT Master Trainer Anna Yu

Recently we sat down with the February Winners of Nomad Hackathon and interviewed them about the experience of learning how to code at Preface using App Inventor and Scratch.

Nomad Hackathon is a monthly coding event in which the young coding students in Preface create useful apps for the local community. In February, we witnessed two groups of coding students transforming into product makers. Brandon, Sik Kin and Macarius teamed up and created a loyalty app using App Inventor, while Jacqueline created an interactive translation app with Scratch.

The Beginning

(From left to right) Brandon Chan, Sik-kin Chan and Macarius Chan — the brains behind the Preface Coffee Loyalty App

Brandon, Sik Kin and Macarius have been coding for years now. None of them were older than 10 years old when they first started coding.

“I was five when I started learning Scratch”, smiled Brandon. At the age of 10, he has already coded up more apps than an average adult in Hong Kong. Both Brandon and Macarius started coding because they wanted to have their own creations. “I liked to play video games a lot, and I was very curious about how to make one myself. But then my day school doesn’t really teach us that.”

“I was five when I started learning Scratch”, smiled Brandon. At the age of 10, he has already coded up more apps than an average adult in Hong Kong.

The First Challenge

It’s a big problem that the local school system sees as non-existent. While there is some form of computer classes at school, it hardly matches the learning needs of school kids.

“My school doesn’t provide any coding classes until I get older.”

Jacqueline explained why she started coding at Preface.

Even when there’s a class, it still doesn’t guarantee a chance to learn. “The coding projects at school are sometimes too easy. By the time the teacher finished explaining what the project is, I have already done most of the codes for it”, shrugged Macarius.

Tackling the Challenge

The average class size of a day school in Hong Kong is 32 kids, all with different personal experiences, interests and needs in learning. The challenge for a teacher to ensure the teaching quality and class engagement is monstrous and, as a matter of fact, unrealistic.

Brandon compared his experience at school with Preface and revealed the fundamental difference in learning experience owing to the class size.

“The class is too big and the teacher cannot answer every question we have. However, at Preface, every group class has only two to three kids. Our teacher never fails to answer our questions. They also teach us how to find the answer ourselves instead of telling us the answer straight away. And the projects are so fun to work on.”

“At Preface, every group class has only two to three kids. Our teacher never fails to answer our questions. And the projects are so fun to work on.”

— Brandon Chan, App Inventor student at Preface Nomad

Sik-kin put his shyness away with excitement when he talked about the games he built with App Inventor, such as Space Shooting Fun or Farming RP.

“We learn really fast while making these fun games”, Sik-kin continued, “we like the challenges”.

— Sik-kin Chan, App Inventor student at Preface Nomad

Hacking Education with Hackathon

While they learn how to work independently in regular classes, our coding students learn to collaborate and leverage the strength of each other during Nomad Hackathon.

“I’ve never missed a single Hackathon after I started having coding classes here. I want to see what other kids are doing and learn from them”, said Brandon.

The high relevance of the Hackathon projects to real-life problems is proved very effective in motivating students to practise what they’ve learnt.

Hackathon is much more valuable for their learning than a simple exercise or exam that only challenges their short-term memory. Coding is a brand new subject for young kids; it requires a brand new approach in delivering the know-how. The century-old setup of an overcrowded classroom is failing hard as our new generation of learners has told us. Getting the approach right is half the battle done; at Preface, we place a strong focus on the approach. We keep our classes small, our projects relevant, and our students highly engaged.

Coding is a brand new subject for young kids; it requires a brand new approach in delivering the know-how.

At the end of the day, we give them a stage — Preface Hackathon is not just another coding class; it is a platform for the young students to prove to themselves — and the community — that they have learnt something exciting.


Sik-kin concluded our conversation with a big picture of himself in the future.

“I want to be a professional coder when I grow up, and teach young kids about coding with what I know from my years.”

Although Sik-kin is only 10 years old now, his vision doesn’t seem too wild for us. We are confident that our young students will give back to the community in their own ways in a not-so-distant future.

Congratulations to our February Winners again!

Envisioning a World Powered by Artificial Intelligence

Image credit: Engadget

Over the past century, fiendish sci-fi plots like The Terminator or The Matrix have always portrayed scenarios where sophisticated AIs end up manipulating the human race. Coupled with the idea of robots and computers taking over a multitude of our jobs, incremental AI developments have widely been perceived as menaces that bring future sufferings.

However, instead of worrying about job replacements, Preface celebrates the impending displacements of tasks with the impact of new technologies. The automation of repetitive tasks is a key advantage of implementing such technologies, leaving humans with greater capacity to deal with higher-level tasks, resulting in the facilitation of efficiency and innovations.

One pick for innovative concept is Toyota’s e-Palette, an on-demand city platform with autonomous and multipurpose driverless shuttles serving across the city. These shuttles have an open interior design layout that enables companies of all kinds to use them in accordance with users’ needs, whether it be mobile meeting rooms, retail outlets, restaurants, emergency medical clinics, on-the-road e-commerce or more. Imagine being able to call up a mobile fitting room before placing an order on online shopping sites — no longer will you buy goods that do not match your expectations and have so much hassle returning them. Its flexible framework empowers businesses with mobility and resource optimization, while supporting their customers’ lifestyles with better convenience, productivity and efficiency. Yet, other potential benefits are there to be explored in the real world.

Statistically, 47% of digitally mature organisations have a defined A.I. strategy. — Adobe

In 2019, we are going through a significant transition from an information-driven era to an AI-powered age. The problem of information overload has been forcing us to change our behaviour, from receiving information passively to having quality learning experience. With the advancement of AI, machines can assist us by handling vast amount of behavioural data and suggest us personalised recommendations accordingly. Just as the case of Toyota’s e-Palette, the Education field deserves to undergo the same intensity of revolution for more efficient and effective outcomes.

Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it’s stupid.” — Albert Einstein

Educators need to know what theories or explanations in textbooks cause most frustrations to learners, and what pedagogical methods work for diverse groups of learners. An education based AI machine is best to provide us with objective recommendations of the learning method and pace for each individual learner. In this way, the collaboration of human teachers and AI machine would help to educate the next generation of humans to be smarter than ever.

The Idea Behind the NYR Campaign

There was an idea. That emerging knowledge did not need to be hard to learn. That Preface, as an education and tech company, could be the ideal educator to deliver this knowledge. Hence, since its inception in late June 2018, Preface Coffee has served as a platform for workshops that aim to create conversations on emerging knowledge essential for the technological era. Held by Preface educators and guest speakers, Preface Workshops remained a staple event through the months, slowly building the reputation as a hub for new knowledge in Tin Hau.

As we approached the turn of the New Year, there was a thought. Why stop at emerging knowledge? Many people have various skills and particular topics that they’d love to learn about, but have no clue on where to start their journey — none more so than individuals who are looking to learn something new in the upcoming year. Fuelled with the idea of motivating people to not only make, but complete New Year Resolutions in learning, we set up the New Year’s Resolutions Campaign.

As a channel that provides participants with greater access to learning their topics of interest, the NYR Campaign incentivises individuals to place learning as a priority in their lives. The result was instantaneous, with Preface Workshops reaching record attendances in the first month of the campaign, and effectively ignited public interest in new knowledge.

Preface Workshops Revisit: Month of Blockchain


Blockchain Technology: Hitchhiker’s Guide to Blockchain

Preface Coffee had the honour of hosting Mr. Michael Yung, Head of Digital Products and Technology at Asia Miles on the night of 21st January. An experienced figure in the world of Blockchain as a result of his impressive work on refining Asia Miles’ very own loyalty programme, Mr. Yung captivated the audience with his talk on Blockchain and its usage in cryptocurrency.

Through the workshop, Mr. Yung allowed participants to understand Blockchain by breaking its concepts down into visualizable, easy-to-follow procedures, before delving into its application in Bitcoin — the most popular cryptocurrency in the world to date. The talk gradually built on to real use cases of Blockchain, in which an eager audience was introduced to how blockchain could be implemented into numerous industries. A plethora of questions were raised, stimulating an interactive discussion and exchange of ideas that transcended beyond a common workshop.

Preface would like to take the opportunity to thank Mr. Yung for his inspiring and eye-opening talk, and will aspire to continue attracting high calibre speakers to future Preface Workshops!


Blockchain Technology 101


Blockchain 101 recorded Preface Workshop’s highest attendance in its short history, as participants from many different backgrounds gathered to learn about a technological phenomenon predicted to deliver an impact similar to that of the internet two decades ago. Fresh from his studies in Oxford’s Blockchain Course, Preface Founder and CEO Tommie Lo guided participants through intricate concepts of Blockchain, and introduced their possible use in a wide range of business scenarios through Hyperledger, a global collaborative effort facilitating blockchain technology across different industries, and backed by numerous conglomerates.

Preface Coffee is re-running this popular workshop in March 2019.


Why Do We Teach Blockchain

We have been adhering to the vision of bringing emerging knowledge to the Preface Coffee space since the first day of launch; liberalising proprietary knowledge pieces from graduate schools to a community we love, believing that there’s nothing cannot be learnt, and we then apply the knowledge to make a difference in the world.

We therefore teach Blockchain Technology as we believe in its power to become a revolutionary enterprise application. Our Blockchain workshops aim to deliver a deeper public understanding through diving into Blockchain Technology with cryptography and delving into its relationship with cryptocurrencies like Bitcoin.

Hello, Future: The Rise of Blockchain and Its Implications

Image credit: coincodex

Widely regarded as the greatest invention in the past century, the Internet has drastically transformed the way we live our lives, granting us access to treasures of knowledge, instant information, and unparalleled social connectivity all over the world. Ironically, given the information obtainable, it is ultimately the Internet that has also become the causation of increasing fraudulent behaviour and lack of trust among humans.

Whether you’re a coffee shop owner looking to import some high quality coffee beans, or you’re simply trying to find a nice dress on an online shop, you’re prone to the same risk of being conned. In the same way that you cannot verify whether you’re buying high quality fair trade beans before receiving them, neither will you be able to tell whether the dress you’re buying would look the same as it does on the website in its real form. The key to solving this trust and verification issue? Blockchain.

The Blockchain Solution

As a decentralised, distributed digital public ledger, Blockchain enables transactions to be recorded and linked across a high number of computers, meaning alterations to any records would also require further changes to subsequent transactions, making Blockchain theoretically unalterable. Blockchain rose to popularity as the underlying technology behind popular cryptocurrency Bitcoin, and in recent years, leading corporations like IBM, JP Morgan, Intel and the Linus Foundations have led a Hyperledger project to develop Blockchain Technology on enterprise application level.

Why the hype? Whilst Blockchain may not revolutionize every profession, there are many niche industries that can still benefit from Blockchain’s immutable system. Apart from obvious benefits to the finance industry through cryptocurrency, Blockchain can also revolutionise supply chains by flawlessly tracking goods from its supplier to point of delivery, eliminate fraudulent insurance claims or loopholes by recording and storing claims and payments, and remove the middleman in transactions by eliminating the inherent trust issues and reliance on ‘good faith’ evident in the contracts between individuals, companies or organisations. These are just some of many prime examples of how Blockchain can transform key industries.

With Blockchain, we fill a void culminated by the lack of trust built by the Internet, and complete its biggest flaw. Blockchain is technology’s great step into, and ultimately is, the future.

If you want to take a closer look at how Blockchain works and its applications in the real world, Preface Coffee is hosting Blockchain 101 workshop in which the founder of Preface.ai will take the audience through the brief history of Blockchain, how it works as a decentralised mechanism, and why it is one of the most important innovations in the 21st century.
