PWA, Native Apps, oh my! Making sense of the evolving web app landscape

We all love web code, but there is only so much you can do in the browser. Native apps allow you to do more, but trying to shoehorn web code into a native experience historically hasn't served our users well. Things are different now. As it turns out, we no longer have to compromise between a great user experience and our familiarity with HTML, CSS, and JavaScript.

In this talk, we’ll work to make sense of the evolving web app landscape. We'll cover everything from Progressive Web Apps to React Native to Electron to HWAs, and look at how you can maintain one web code base while still ensuring your apps run brilliantly both in your browser as well as natively on iOS, Android, and desktop devices.

Progressive Web Apps to the Rescue

Mixed Reality: Where the virtual world meets IoT

Virtual Reality and the Internet of Things are two of the most important technologies that arise in the past years. VR has the potential to change the world in some surprising ways, while Internet of Things already has transformed the way we live our lives. It is the confluence of these two technologies, that offers the most promising opportunity of all. In this talk, we'll introduce Samsung's big vision on IoT. How we build Samsung ARTIK from Module to Cloud and how we combine IoT and webVR to connect the real world to virtual reality.

Getting To Grips With CSS Grid

CSS grid finally brings 2D layouts to CSS, with some incredibly powerful tools for creating beautiful responsive layouts. We’ll start with the basics of Grid and then explore how to build some common layouts that you’ll see often around the web, along with some advice on what grid is not for!

We’ll take a trip through the history of web layout from tables to flex to learn the good the bad and the ugly of coding up a design and the problems that grid can fix. We’ll then cover the basic language of Grid and Grid composition using some responsive layouts as examples; finishing with the ‘holy grail’ layout built in 5 lines of CSS. Grid, however, isn’t here to kill all other layout methods so it is worth mentioning that other tools, such as flex, are still very useful and valid. We’ll then go on to cover some more advanced uses of Grid such as template area naming and how and why we might implement a subgrid-like effect using display:contents.

A Rube Goldberg Machine & New Web Technology

There are some really large powerful tools landing in the browser in recent months. For example CSS Grid, Web Animations, Custom CSS Properties and Web Components. Each topic on it's own is complex and worth learning in depth. But I aim to show how exciting they be when used together.

The Hateful Weight

Web development and the technologies employed are complex. What is not a Gordian knot is image weight. Image weight is oft a red herring of poor management resulting in poor #ux, along with dissolution of users’ data plans. With the world moving from mostly to near exclusively, data sensitive mobile clients, image optimization is crucial component of asset management. Making learned decisions about images is critical, from formats to art direction. The Hateful Weight will discuss:

  • Formats, new and old.
  • Their strengths and short comings
  • The tools and strategies to oversee their optimizations
  • And the need to address a varied and worldly audience.

At the denouement, attendees will have a much better understanding and grasp of image formats, the need for their management and optimization and the urgent necessity to consider and build for new markets.

Day 2: Friday 20th

The art of noise (keep talking)

Voice interaction is now commonplace: we converse with the digital assistants on our phones and our connected home devices, and the experience is improving all the time. But how do we design experiences for voice interaction? What can we learn from the experiences of using first generation voice input/output technologies like screen readers and speech recognition tools?

Game mechanics powered by the Gaze-At-Ratio (GAR)

Learn how content creators and publishers can measure a user's depth of attention and engagement to 3D objects in both VR/AR environments without disrupting the content or the user experience, and then employ that metric for various applications like A/B testing, content triggering, and monetization. One approach is powered by the Gaze-At-Ratio (GAR), an algorithm that determines the value of a user's gaze to a 3D object by factoring in the relative distance, duration, and depth of a user’s orientation as the object enters and exits their field of view.
