Amazon Alexa Voice Services Bringing Amazon’s "Alexa Everywhere" vision to third-party living room ecosystems (starting with flagship LG TVs) required solving a fundamental interaction conflict: ambient voice queries could easily obliterate active, lean-back television viewing.

The experience needed a framework that replaced invasive full-screen visual takeovers with a system that respected live media playback across seven distinct domain verticals (Music, Knowledge, Smart Home, Weather, Video, Shopping, and Lists).

APL Responses on LG 2019 TVs

Defined the core multimodal interaction standards and spatial governance rules leveraging Alexa Presentation Language (APL).

DESIGN TENNETS

(1)
POLITE GUEST
Alexa is always a polite guest. We respect the user's environment by ensuring interactions are unobtrusive, context-aware, and seamlessly integrated.

(2)
SEAMLESS FOCUS
Move the user's focus seamlessly from activity to activity. Let users move between tasks without losing their current context or momentum.

(3)
PROPORTIONAL VALUE
If we increase disruption, we also must increase value. Any interruption must be justified by providing immediate, highly relevant information.

(4)
ALLOW CORRECTION
Take a best guess and allow for correction (e.g. settings). We confidently anticipate the need to reduce upfront user effort.

(5)
PREDICTABLE & FLEXIBLE
Make the experience predictable for Device Makers and end users, while keeping implementation easy and flexible for Experience Makers.

(6)
EASY IMPLEMENTATION
Make implementation both easy and flexible for Experience Makers. We provide modular, well-documented frameworks that reduce developer friction.

APL CX VS. AVS GUI & FIRE TV

(1)
NEW VISUAL DOMAINS
This CX includes visuals for three additional features: music search, jokes, and “Where's my stuff?”

(2)
UPDATED VISUAL STYLE
The visual style has been updated to match the latest Visual DNA styles.

(3)
SMALLER PARTIAL SCREEN
Instead of using a bottom third, the LG CX uses a card which adds as much value in less space.

(4)
FULL SCREEN CAPABILITY
Interaction updates include the ability for a user to make a partial screen response go full screen.

(5)
ADJUSTED TIMEOUTS
Fire TV uses long timeouts; our tenet is to flow users seamlessly from one experience to another. To do so, we will shorten the timeouts in order to bring users back to their primary activity.

INTERACTION MODEL

(1)
Voice Chrome
LG 2019 will use the circular voice chrome already implemented by the AVS LG team.

(2)
System Chrome
For LG 2019 TVs, visual experiences will display in either full screen or card. In the future, there will also be the need for a toast.

Full Screen

A full-screen response is appropriate for: Media playback (to avoid overlapping audio), Experiences intended to have a prolonged back-and-forth (e.g., games), and search results (although a card may also be appropriate).

Bottom Card

A card is appropriate for: Short experiences (aka “short-running” or “transactional”), search results (fullscreen is also appropriate) and secondary media (e.g.smart home camera).

Cards have limited real estate, but can be scrollable.

Toast

Toasts are appropriate for unprompted notifications that require no action. Since LG TVs will not launch with notifications, we will not need toasts until a later release.

(3)
Session Pivots
Domains may provide an affordance to let the user maximize a card to full screen. This is accessed via an up arrow on the remote or by voice.

Session Pivot via Remote: Default Focus

Architected a dynamic collision matrix that balanced audio ducking against automatic playback pauses, while establishing scalable system chrome hierarchies—routing quick transactional interactions into contextual partial-screen cards and reserving full-screen viewports for deep, user-directed media exploration without breaking broadcast immersion.

Session Pivot Flow

VISUAL DESIGN

(1)
FULL-SCREEN VIEWPORT
Safe-Zone Margin: 96px (Overscan boundary)
Column Gutters: 32px
Baseline Offset: 80px (System chrome & persistent voice HUD)

Intent: Immersive browsing; replaces background playback for complex, high-density media catalogs.

(2)
PARTIAL-SCREEN OVERLAY
Container Margins: 48px
Internal Gutters: 16px
Spatial Anchor: Lower-third / right-docked card framework

Intent: Non-disruptive transactional queries (Weather, Smart Home, Timers) preserving active video sightlines.

(3)
DYNAMIC COMPONENT BOUNDS
Max Card Height: 570px (Caps card footprint to <50% screen height on 1080p) Min Card Height: 294px (Maintains legible 10-foot viewing typography)

Constraint Logic: Strict vertical bounds prevent voice responses from occluding primary subtitles and live broadcast feeds.
