The horror …the horror.

The Layouts of Tomorrow | Max Böck - Frontend Web Developer

A walkthrough of the process of creating a futuristic interface with CSS (grid and animation).

While this is just one interpretation of what’s possible, I’m sure there are countless other innovative ideas that could be realized using the tools we have today.

Pixels vs. Ems: Users DO Change Font Size – Evan Minto – Medium

I have to admit, I didn’t realise that text reszing behaved differently for user preferences compared to page zoom. For that reason alone, I’m going to avoid setting font sizes in pixels.

If 2 to 3% (or more!) of your users are relying on a custom font size, you should know that so you can either support that user preference or make a conscious decision to not support it. Doing anything less is frankly irresponsible, especially considering that users with larger font sizes may be using those sizes to compensate for visual disabilities.

Untold AI: The Untold | Sci-fi interfaces

Prompted by his time at Clearleft’s AI gathering in Juvet, Chris has been delving deep into the stories we tell about artificial intelligence …and what stories are missing.

And here we are at the eponymous answer to the question that I first asked at Juvet around 7 months ago: What stories aren’t we telling ourselves about AI?

Recursive Recipes | Make food from scratch

Watch the prep time increase as you make more and more of a recipe’s ingredients from scratch.

I guess Carl Sagan was right. To make an apple pie from scratch, you must first invent the universe.

Name That Script! by Trent Walton

Trent is about to pop his AEA cherry and give a talk at An Event Apart in Boston. I’m going to attempt to liveblog this:

How many third-party scripts are loading on our web pages these days? How can we objectively measure the value of these (advertising, a/b testing, analytics, etc.) scripts—considering their impact on web performance, user experience, and business goals? We’ve learned to scrutinize content hierarchy, browser support, and page speed as part of the design and development process. Similarly, Trent will share recent experiences and explore ways to evaluate and discuss the inclusion of 3rd-party scripts.

Trent is going to speak about third-party scripts, which is funny, because a year ago, he never would’ve thought he’d be talking about this. But he realised he needed to pay more attention to:

any request made to an external URL.

Or how about this:

A resource included with a web page that the site owner doesn’t explicitly control.

When you include a third-party script, the third party can change the contents of that script.

Here are some uses:

  • advertising,
  • A/B testing,
  • analytics,
  • social media,
  • content delivery networks,
  • customer interaction,
  • comments,
  • tag managers,
  • fonts.

You get data from things like analytics and A/B testing. You get income from ads. You get content from CDNs.

But Trent has concerns. First and foremost, the user experience effects of poor performance. Also, there are the privacy implications.

Why does Trent—a designer—care about third party scripts? Well, over the years, the areas that Trent pays attention to has expanded. He’s progressed from image comps to frontend to performance to accessibility to design systems to the command line and now to third parties. But Trent has no impact on those third-party scripts. That’s very different to all those other areas.

Trent mostly builds prototypes. Those then get handed over for integration. Sometimes that means hooking it up to a CMS. Sometimes it means adding in analytics and ads. It gets really complex when you throw in third-party comments, payment systems, and A/B testing tools. Oftentimes, those third-party scripts can outweigh all the gains made beforehand. It happens with no discussion. And yet we spent half a meeting discussing a border radius value.

Delivering a performant, accessible, responsive, scalable website isn’t enough: I also need to consider the impact of third-party scripts.

Trent has spent the last few months learning about third parties so he can be better equiped to discuss them.

UX, performance and privacy impact

We feel the UX impact every day we browse the web (if we turn off our content blockers). The Food Network site has an intersitial asking you to disable your ad blocker. They promise they won’t spawn any pop-up windows. Trent turned his ad blocker off—the page was now 15 megabytes in size. And to top it off …he got a pop up.

Privacy can harder to perceive. We brush aside cookie notifications. What if the wording was “accept trackers” instead of “accept cookies”?

Remarketing is that experience when you’re browsing for a spatula and then every website you visit serves you ads for spatula. That might seem harmless but allowing access to our browsing history has serious privacy implications.

Web builders are on the front lines. It’s up to us to advocate for data protection and privacy like we do for web standards. Don’t wait to be told.

Categories of third parties

Ghostery categories third-party providers: advertising, comments, customer interaction, essential, site analytics, social media. You can dive into each layer and see the specific third-party services on the page you’re viewing.

Analyse and itemise third-party scripts

We have “view source” for learning web development. For third parties, you need some tool to export the data. HAR files (HTTP ARchive) are JSON files that you can create from most browsers’ network request panel in dev tools. But what do you do with a .har file? The site har.tech has plenty of resources for you. That’s where Trent found the Mac app, Charles. It can open .har files. Best of all, you can export to CSV so you can share spreadsheets of the data.

You can visualise third-party requests with Simon Hearne’s excellent Request Map. It’s quite impactful for delivering a visceral reaction in a meeting—so much more effective than just saying “hey, we have a lot of third parties.” Request Map can also export to CSV.

Know industry averages

Trent wanted to know what was “normal.” He decided to analyse HAR files for Alexa’s top 50 US websites. The result was a massive spreadsheet of third-party providers. There were 213 third-party domains (which is not even the same as the number of requests). There was an average of 22 unique third-party domains per site. The usual suspects were everywhere—Google, Amazon, Facebook, Adobe—but there were many others. You can find an alphabetical index on better.fyi/trackers. Often the lesser-known domains turn out to be owned by the bigger domains.

News sites and shopping sites have the most third-party scripts, unsurprisingly.

Understand benefits

Trent realised he needed to listen and understand why third-party scripts are being included. He found out what tag managers do. They’re funnels that allow you to cram even more third-party scripts onto your website. Trent worried that this was a Pandora’s box. The tag manager interface is easy to access and use. But he was told that it’s more like a way of organising your third-party scripts under one dashboard. But still, if you get too focused on the dashboard, you could lose focus of the impact on load times. So don’t blame the tool: it’s all about how it’s used.

Take action

Establish a centre of excellence. Put standards in place—in a cross-discipline way—to define how third-party scripts are evaluated. For example:

  1. Determine the value to the business.
  2. Avoid redundant scripts and services.
  3. Fit within the established performance budget.
  4. Comply with the organistional privacy policy.

Document those decisions, maybe even in your design system.

Also, include third-party scripts within your prototypes to get a more accurate feel for the performance implications.

On a live site, you can regularly audit third-party scripts on a regular basis. Check to see if any are redundant or if they’re exceeding the performance budget. You can monitor performance with tools like Calibre and Speed Curve to cover the time in between audits.

Make your case

Do competitive analysis. Look at other sites in your sector. It’s a compelling way to make a case for change. WPO Stats is very handy for anecdata.

You can gather comparative data with Web Page Test: you can run a full test, and you can run a test with certain third parties blocked. Use the results to kick off a discussion about the impact of those third parties.

Talk it out

Work to maintain an ongoing discussion with the entire team. As Tim Kadlec says:

Everything should have a value, because everything has a cost.

Building More Expressive Products by Val Head

It’s day two of An Event Apart in Boston and Val is giving a new talk about building expressive products:

The products we design today must connect with customers across different screen sizes, contexts, and even voice or chat interfaces. As such, we create emotional expressiveness in our products not only through visual design and language choices, but also through design details such as how interface elements move, or the way they sound. By using every tool at our disposal, including audio and animation, we can create more expressive products that feel cohesive across all of today’s diverse media and social contexts. In this session, Val will show how to harness the design details from different media to build overarching themes—themes that persist across all screen sizes and user and interface contexts, creating a bigger emotional impact and connection with your audience.

I’m going to attempt to live blog her talk. Here goes…

This is about products that intentionally express personality. When you know what your product’s personality is, you can line up your design choices to express that personality intentionally (as opposed to leaving it to chance).

Tunnel Bear has a theme around a giant bear that will product you from all the bad things on the internet. It makes a technical product very friendly—very different from most VPN companies.

Mailchimp have been doing this for years, but with a monkey (ape, actually, Val), not a bear—Freddie. They’ve evolved and changed it over time, but it always has personality.

But you don’t need a cute animal to express personality. Authentic Weather is a sarcastic weather app. It’s quite sweary and that stands out. They use copy, bold colours, and giant type.

Personality can be more subtle, like with Stripe. They use slick animations and clear, concise design.

Being expressive means conveying personality through design. Type, colour, copy, layout, motion, and sound can all express personality. Val is going to focus on the last two: motion and sound.

Expressing personality with motion

Animation can be used to tell your story. We can do that through:

  • Easing choices (ease-in, ease-out, bounce, etc.),
  • Duration values, and offsets,
  • The properties we animate.

Here are four personality types…

Calm, soft, reassuring

You can use opacity, soft blurs, small movements, and easing curves with gradual changes. You can use:

  • fade,
  • scale + fade,
  • blur + fade,
  • blur + scale + fade.

Pro tip for blurs: the end of blurs always looks weird. Fade out with opacity before your blur gets weird.

You can use Penner easing equations to do your easings. See them in action on easings.net. They’re motion graphs plotting animation against time. The flatter the curve, the more linear the motion. They have a lot more range than the defaults you get with CSS keyword values.

For calm, soft, and reassuring, you could use easeInQuad, easeOutQuad, or easeInOutQuad. But that’s like saying “you could use dark blue.” These will get you close, but you need to work on the detail.

Confident, stable, strong

You can use direct movements, straight lines, symmetrical ease-in-outs. You should avoid blurs, bounces, and overshoots. You can use:

  • quick fade,
  • scale + fade,
  • direct start and stops.

You can use Penner equations like easeInCubic, easeOutCubic and easeInOutCubic.

Lively, energetic, friendly

You can use overshoots, anticipation, and “snappy” easing curves. You can use:

  • overshoot,
  • overshoot + scale,
  • anticipation,
  • anticipation + overshoot

To get the sense of overshoots and anticipations you can use easing curves like easeInBack, easeOutBack, and easeInOutBack. Those aren’t the only ones though. Anything that sticks out the bottom of the graph will give you anticipation. Anything that sticks out the top of the graph will give you overshoot.

If cubic bezier curves don’t get you quite what you’re going for, you can add keyframes to your animation. You could have keyframes for: 0%, 90%, and 100% where the 90% point is past the 100% point.

Stripe uses a touch of overshoot on their charts and diagrams; nice and subtle. Slack uses a bit of overshoot to create a sense of friendliness in their loader.

Playful, fun, lighthearted

You can use bounces, shape morphs, squashes and stretches. This is probably not the personality for a bank. But it could be for a game, or some other playful product. You can use:

  • bounce,
  • elastic,
  • morph,
  • squash and stretch (springs.

You can use easing equations for the first two, but for the others, they’re really hard to pull off with just CSS. You probably need JavaScript.

The easing curve for elastic movement is more complicated Penner equation that can’t be done in CSS. GreenSock will help you visual your elastic easings. For springs, you probably need a dedicated library for spring motions.

Expressing personality with sound

We don’t talk about sound much in web design. There are old angry blog posts about it. And not every website should use sound. But why don’t we even consider it on the web?

We were burnt by those terrible Flash sites with sound on every single button mouseover. And yet the Facebook native app does that today …but in a much more subtle way. The volume is mixed lower, and the sound is flatter; more like a haptic feel. And there’s more variation in the sounds. Just because we did sound badly in the past doesn’t mean we can’t do it well today.

People say they don’t want their computers making sound in an office environment. But isn’t responsive design all about how we don’t just use websites on our desktop computers?

Amber Case has a terrific book about designing products with sound, and she’s all about calm technology. She points out that the larger the display, the less important auditive and tactile feedback becomes. But on smaller screens, the need increases. Maybe that’s why we’re fine with mobile apps making sound but not with our desktop computers doing it?

People say that sound is annoying. That’s like saying siblings are annoying. Sound is annoying when it’s:

  • not appropriate for the situation,
  • played at the wrong time,
  • too loud,
  • lacks user control.

But all of those are design decisions that we can control.

So what can we do with sound?

Sound can enhance what we perceive from animation. The “breathe” mode in the Calm meditation app has some lovely animation, and some great sound to go with it. The animation is just a circle getting smaller and bigger—if you took the sound away, it wouldn’t be very impressive.

Sound can also set a mood. Sirin Labs has an extreme example for the Solarin device with futuristic sounds. It’s quite reminiscent of the Flash days, but now it’s all done with browser technologies.

Sound is a powerful brand differentiator. Val now plays sounds (without visuals) from:

  • Slack,
  • Outlook Calendar.

They have strong associations for us. These are earcons: icons for the ears. They can be designed to provoke specific emotions. There was a great explanation on the Blackberry website, of all places (they had a whole design system around their earcons).

Here are some uses of sounds…

Alerts and notifications

You have a new message. You have new email. Your timer is up. You might not be looking at the screen, waiting for those events.

Navigating space

Apple TV has layers of menus. You go “in” and “out” of the layers. As you travel “in” and “out”, the animation is reinforced with sound—an “in” sound and an “out” sound.

Confirming actions

When you buy with Apple Pay, you get auditory feedback. Twitter uses sound for the “pull to refresh” action. It gives you confirmation in a tactile way.

Marking positive moments

This is a great way of making a positive impact in your user’s minds—celebrate the accomplishments. Clear—by Realmac software—gives lovely rising auditory feedback as you tick things off your to-do list. Compare that to hardware products that only make sounds when something goes wrong—they don’t celebrate your accomplishments.

Here are some best practices for user interface sounds:

  • UI sounds be short, less than 400ms.
  • End on an ascending interval for positive feedback or beginnings.
  • End on a descending interval for negative feedback, ending, or closing.
  • Give the user controls to top or customise the sound.

When it comes to being expressive with sounds, different intervals can evoke different emotions:

  • Consonant intervals feel pleasant and positive.
  • Dissonant intervals feel strong, active, or negative.
  • Large intervals feel powerful.
  • Octaves convey lightheartedness.

People have made sounds for you if you don’t want to design your own. Octave is a free library of UI sounds. You can buy sounds from motionsound.io, targetted specifically at sounds to go with motions.

Let’s wrap up by exploring where to find your product’s personality:

  • What is it trying to help users accomplish?
  • What is it like? (its mood and disposition)

You can workshops to answer these questions. You can also do research with your users. You might have one idea about your product’s personality that’s different to your customer’s. You need to project a believable personality. Talk to your customers.

Designing for Emotion has some great exercises for finding personality. Conversational Design also has some great exercises in it. Once you have the words to describe your personality, it gets easier to design for it.

So have a think about using motion and sound to express your product’s personality. Be intentional about it. It will also make the web a more interesting place.
