A Machine Learning Halloween at Nomad

It’s the Halloween season and Preface Hackathon is infested by a bunch of friendly ghosts! On last Sunday, The Nomad recruited teams of App Inventor and Scratch students to find these ghosts using machine learning.

Our App Inventor students built a smart app using image recognition for Halloween this year!

Building “Ghostbusters” with MIT App Inventor

This year many friendly ghosts hid inside QR codes. The mission of our ghostbusters (aka the App Inventor students) is to bust as many ghosts as possible – all done with a self-built app. Students learnt how to build a mobile app that makes use of QR code scanning and image recognition plugin to accomplish their mission in the Halloween-themed campus.

MIT Scratch – Digital Costume using Facial Recognition

Physical Halloween costumes are so predictable. This year our Scratch students created their very own digital costume using facial recognition technology. In this Hackathon, they learnt how to design and wear their own digital costumes using Scratch, and build interactive Halloween games using the facial recognition tech and motion sensors.

All our students are ready for Halloween with their own shiny apps this year, what about you?

HK Children built Burger Ordering App for local restaurant

It’s 11:30 in the morning, 45 minutes away to your lunch break. Having been in a rush and skipped breakfast, you are suffering from the complaint of your rumbling stomach. Here, you pick up a tablet, access an app and start ordering your customized burger. You choose from a selection of buns, vegetables, patties to a list of chefs secret sauce. When you are ready, a simulated mouthwatering burger appears in front of you. Then you place your order and grab your burger out of your office right at 12:15.

This is what our coders aged 9-12 built during the Preface Hackathon last Sunday – a “Create Your Own Burger” custom app for Hong Kong burger chain Texas Burger, which was structured with Variables and ListPicker components, and further fine-tuned with Procedure components and colour coding. As aforementioned, the app provides enhanced visualization for customers, and also serves as a confirmation tool for store owners to minimize wrong orders.

All kids are born with limitless creativity. Give them a platform to channel their abilities, and they may end up with creations with larger impacts than any adult could fathom. There is an ever growing influence of coding knowledge in the real world, and hence, newer platforms for kids creativity are needed to reflect this change. The App Inventor blocks that our coders have thoroughly explored may be interpreted as the next “Lego”.

This was well reflected in our Hackathon. Though many kids at the event were young, and had little experience with coding, they exhibited a passion and excitement for coding that stunned their own parents. They were fully engaged throughout, and were buzzing to contribute in any way they could. This bodes well with our role as Preface Programmers – to guide young coders in not only learning, but applying coding knowledge practically too. We are extremely proud of every kid for the work theyve put in, and would also like to take this opportunity to thank Texas Burger for being a reliable partner all through this event!
