Remember the first time you used an iPad?



...and THE FIRST TIME YOU USED A 

smart tv?



The iPad has captured our imagination, but Smart TVs have not (yet).

After 80 years the TV format has remained largely unchanged

Improvements come from technical performance and increased TV program offer:
  • Emergence of new channels
  • Remote control
  • From B&W to Colour TV
  • Digitization process (DVB)
  • CRT>Flat>Plasma>LCD>LED>OLED>? 
  • 3D, HD, 4K...

Sports could be a Smart TV killer app.

THE KILLER APP


Hyper-personalized Apps in a way that wouldn't be possible with a traditional TV.

"Imagine a workout channel that connects you directly to your personal trainer, who is able to give you feedback thanks to a built-in webcam."

It won’t look anything like TV!

  • User Environment
  • UX Principles
  • How to Facilitate Easier Use for a Better UX

DESIGN PRINCIPLES

User Environment

10-foot user interface (3 meters)

People lean back and relax  while watching TV.
Not used to complex screen layouts and controls.
TV screens are larger and viewed from a greater distance.
Legibility must be considered for this distance.
Size of text and other elements must be adjusted accordingly.

DESIGN PRINCIPLES

USER ENVIRONMENT

The standard Remote is the fundamental TV control

App navigation using only:
selection, return, and exit buttons.

Control feedback must be instant and distinct.

When applying a pointing navigation system:
  • The pointer must be large enough
  • Avoid complex and detailed navigations
  • Pointed at areas must be large and clearly identifiable

DESIGN PRINCIPLES

USER ENVIRONMENT

TV is used by more than one person

What happens when more than one person is using the device?

Precaution measures when:
  • Showing sensible info (credit cards, passwords...)
  • Sign-in service is available (who the signed-in user is?)

DESIGN PRINCIPLES

UX Principles

Simplicity

Complex App        Better App

The layout should be: 
  • user-friendly (easy to access features)
  • simple (with few depth levels)

Apps should not require a separate guide or a manual.

DESIGN PRINCIPLES

UX PRINCIPLES

Clarify

Clear and accurate navigation functions (move, return, enter...) for user operations.

Ambiguous navigation cause users:
  • Feel confused and insecure
  • Close the App, and may never use it again

Users should always know exactly 
where they are within an App.

DESIGN PRINCIPLES

UX PRINCIPLES

User Control

The control method must account for the control device, and an intuitive layout must be provided accordingly.

The button names and icons on the remote control must match the actions that occur on the screen.

The movements that occur on the screen must be in the direction expected by the user.

DESIGN PRINCIPLES

UX PRINCIPLES

Consistency

Closely related to improvements in usability and learnability.

When using a new App, experience with a similar App will ensure fast learning.

Not always possible to (re)use the same UI for every App.

DESIGN PRINCIPLES

UX PRINCIPLES

Consistency

How to enable users to become familiar with common controls, and use Apps more easily?

  • Consistency of Controls
  • Consistency of Screen Layout
  • Consistency of Navigation

DESIGN PRINCIPLES

UX PRINCIPLES

Feedback

Clear display of items that can be selected using the focus.

Show loading animations if time exceeds.

DESIGN PRINCIPLES

UX PRINCIPLES

Aesthetic Considerations

Aesthetically pleasing design:
  • Makes Apps look simple to use
  • Increases the chances of them being used again
  • Helps users have a positive experience

Attention to TV-specific design factors:
  • Colour
  • Resolution
  • Screen composition

design principles

How to Facilitate Easier Use for a Better UX

Focus
The Focus is the element that highlights a selectable component and signifies the user’s current on-screen location.

Good(left) and bad(right) examples of focus.

DESIGN PRINCIPLES

HOW TO FACILITATE EASIER USE FOR A BETTER UX

Navigation
Navigational movements must be predictable.
Using a grid is the best way to minimize confusion.

Confusion caused by diagonal placement.

DESIGN PRINCIPLES

HOW TO FACILITATE EASIER USE FOR A BETTER UX

Minimize Screen Transition
Frequent screen transitions will make the users feel lost and make the App difficult to navigate.

A good example is flat navigation with 2 levels.

Making TV smart



MAKING TV SMART


Mid ’90s...

  • Idea of bringing Internet content to the living room
  • Pioneers like WebTV Networks set out to revolutionize TV


But 20 years later, the revolution still hasn't materialized.

MAKING TV SMART

Smart TV sell, but don’t work well


Sales of Smart TVs are decent.
All TV makers have an app marketplace on its TV sets.
Many content available on these platforms.

...but the experience for users is often painful. 

Why?
  • Hard to navigate around a smart TV screen using a RC
  • People prefer to connect their PC to the TV

MAKING TV SMART

Your phone is more powerful than your TV


Your phone is cheaper than your TV and has a much smaller screen — but it’s got a lot more processing power.

MAKING TV SMART

Smart TV features are merely bolted on


“They are really still old-style linear TVs with some network feature bolted on.”

Your computer has a standby mode, but your TV doesn't, and that's a problem.

MAKING TV SMART

Netflix pushes TV makers to up their game


Netflix has begun to talk to manufacturers to push them towards rethinking their Smart TV products:
  • Adding on-screen navigation
  • Adding a real sleep mode
  • Simplifying RCs

MAKING TV SMART

It may take four, five, six Netflixes


People just don’t know what to do with their Smart TV.

There’s Netflix, and some people also watch YouTube or Hulu Plus, or stream Pandora on their TVs...

But other than that, not many apps have gained significant traction.

In other words: Smart TVs need more killer apps!

MAKING TV SMART

Standards AREN'T there yet


Where to start? 
Samsung, LG, Google, Yahoo, Roku, Panasonic, Opera...

Roku uses BrightScript (similar to Visual Basic).
Google TV is based on Android (Java).
Yahoo Connected TV widgets are a custom flavour of XML and Javascript that doesn't really work anywhere else.

TV manufacturers are starting to adopt HTML5.
The goal is to deliver the same look and feel across all devices.

MAKING TV SMART

Buyers of dedicated boxes are more engaged


Roku users are expecting to be on the internet, and they are expecting to install applications and to have an app store.

That’s not necessarily true for someone who picks up a smart TV at a mall just because it was on sale.

Makers of TV sets had hoped that app stores would give them a whole new revenue stream, comparable to the income Google and Apple see with their mobile platforms. So far, that revenue hasn't materialized.

MAKING TV SMART

10 feet away, screens work differently


TV has been described as a leanback platform, for a reason: “You are 10 feet away, possibly horizontal”.

Developers need to completely rethink how they present and structure information (Ex. scrolling). 

Smart TV remote controls largely rely on the D-Pad

Everything has to be one or two clicks away to be within reach. 

MAKING TV SMART

Netflix A/B-tests every feature


Netflix famously A/B-tests every significant feature before rolling it out to its general user base.

Ex: Personalized profiles were rolled out on 2013 after more than six months of testing.

MAKING TV SMART

TVs are a shared device


One of YouTube’s takeaways: The TV is a shared device, with many people looking at it at the same time. 

That has huge implications for app design, especially when it comes to sharing potentially sensitive data like the viewing history, including those embarrassing YouTube videos you watched when no one else was around.

MAKING TV SMART

Time to flake out


In the end, even a Smart TV is first and foremost a TV, not a computing device. 

That means that users in most cases aren't looking for interaction, but for entertainmentFor something they can watch, without having to press many buttons or navigate many menus. For the opposite of interactivity.

“TV is not a tool. TV is a purpose. You use it to flake out and let it saturate you, have that experience and let it do the work.”

MAKING TV SMART

Changing the channel without knowing the number


Search, or even entering account credentials on streaming box like Apple TV or Roku is a royal pain (using on-screen keyboards with D-Pad RCs).

After failing with the full keyboard, Google took a different route for its second generation of devices: 
"Remote controls with microphones"

MAKING TV SMART

Your TV is not your friend


Many manufacturers have been experimenting with other ways to move beyond the D-Pad:
  • Voice control on Google, MS's Xbox, and Samsung
  • Wii-like screen pointer on LG TVs, MS's Kinect gesture control, and Haier eye tracking (near future)

Another challenge is ensuring that the technology doesn't make users feel uncomfortable. Speaking to a computer, or even a TV, puts users on the spot.

MAKING TV SMART

Almost like AirPlay, but open





MAKING TV SMART

DIAL and Google Cast could make TVs not just smart, but social and fun


Ready to cast: 
Will DIAL and Google Cast enable the future of social TV?
