AVS Display Cards for TV 1.1
The guidance on this page is based on implementing the TemplateRuntime 1.0 and PlaybackController 1.1 APIs for TVs. If you are using different versions, choose another page from the drop-down menu above. This page contains Tablet-specific Display Card design guidance. For general multimodal best practices, please see Multimodal Display.
Display Cards for Alexa provide visuals to support verbal responses, and give your users an additional modality with which to interact with Alexa.

If you are implementing Display Cards on a device, the Cards should properly display all content, templates, media attributions, and media controls. In addition, we expect that:
- A Display Card will appear as soon as Alexa begins responding or media begins playing, and the Display Card’s contents will match the Alexa response or media.
- Transitions between Display Cards will be smooth, as will the transition into displaying Cards and dismissing Cards.
- Display Cards will respond to screen interactions and voice utterances as described in the design guidelines for your product’s device class.
- Alexa attention states for Listening and Thinking will appear on top of any visible Display Card, and will not be obscured.
Details for each of these are provided in the guidelines below.
Static Display Cards
Global Elements
Alexa shows Static Display Cards in response to certain non-media queries. Cards appear as a sidebar over what the user is watching. All Display Cards in this section have the following global elements.

Notes on the guidelines for static Display Cards
-
All specs are based on a reference template of 1920 x 1080dp.
-
Layout is given in percentages to help adapt the template to your device’s screen resolution.
-
Font sizes are given on the reference screen. These sizes should scale as the resolution of screen changes. If no line-height is given, the line-height is the same as the font size.
-
mainTitle and subTitle should never exceed one line. If the text exceeds the width of the container, the crop the text and use an ellipsis.
-
Image assets and icons marked in dp size should scale as the resolution of screen changes.
-
All of the assets URL can be found in the Asset section of this documentation.
Voice Chrome
Voice chrome is a visual indicator of the Alexa attention states, such as Listening, Thinking, and Responding. Most TVs should use on-screen voice chrome, although it is possible to use on-device LEDs to display the states instead. On-screen voice chrome appears as a circular badge at the bottom-right corner of the screen.

Details of how and when voice chrome should display can be found in the Interactions section below, and in the Interruption Scenarios section on this page. The colors and animations of voice chrome should follow the patterns specified in our Attention System documentation.
Interactions
The user views the following screen states when interacting with Alexa.

Step 1: Invocation
The customer invokes Alexa with the wake word “Alexa” or a button on the remote control. This activates the voice chrome to show Alexa is listening.
Step 2: Listening and thinking
Once Alexa is invoked and voice chrome is displayed, the customer can control Alexa with their voice. If Alexa recognizes an utterance, it processes the intent and display a Card. If Alexa doesn’t hear anything from the customer within 8 seconds, voice chrome dismisses.
Step 3: Response and dismissal
Alexa responds verbally, and when applicable, with a Display Card. The Card should stay up while Alexa is speaking and dismiss automatically when finished. The user can also clear the Card before Alexa is done speaking by using the back button. If the user interrupts Alexa with a new request, Alexa should stop speaking, dim the Card, open the voice chrome, and listen to the new request.
Additional interaction scenarios are described in the Interruption Scenarios section.
BodyTemplate1
BodyTemplate1 is used for Q&A, Wikipedia queries, and third-party Skill requests that do not contain a photo. Sample utterances that would invoke BodyTemplate1 include:
- “How deep is the ocean?”
- “What is the definition of “paradox”?”
- "What is the Karman line?"
- "What is bike polo?"

Style

Layout

Note: Text can extend to 60dp above the logo. Any text past that point should be hidden but accessible by scrolling on a 5-way remote control.

NowPlaying Cards
NowPlaying is used for media requests. Sample utterances that would invoke NowPlaying include:
- “Play jazz music”
- “Play Smoke & Retribution”
- “Play Freakonomics on iHeartRadio”
- “Play a country station from [third-party music provider]”

VUI Playback Commands
The customer can control media playback either using GUI or VUI. VUI playback commands include:
- Play
- Stop
- Cancel
- Pause
- Resume
- Next
- Previous
- Rewind
- Start Over
- Louder
- Softer
- Set Volume
- Mute
- Unmute
- Shuffle
- Restart
- Get details
- Who is this?
Global Elements
Alexa shows the NowPlaying GUI in response to media queries. All NowPlaying Cards in this section have the following global elements.

The global elements in the NowPlaying Card include:
-
Media Metadata
-
Playback controls: These will vary depending on the media type and the service.
-
Progress bar: Appears with most media types.
-
Alexa logo
-
Media artwork: This could be album art, a radio station logo, a program logo, or book artwork.
-
Music Provider Logo: The logo of the service providing the media.
Controls Per Music Service Provider
Alexa can play music from multiple Music Service Providers. Controls vary per provider offering. For example, a live radio station might not have forward and back controls. The correct controls for each offering will be specified in the PlayerInfo directive.
Interactions
The user views the following screen states when interacting with Alexa.

Step 1: Invocation
The customer invokes Alexa with the wake word “Alexa” or using a remote control. This activates voice chrome to show Alexa is listening.
Step 2: Listening and intent processing
Once voice chrome is invoked the customer can control Alexa with their voice. If Alexa recognizes an utterance it will process their intent and display a Card. If not, the voice chrome dismisses.
Step 3: Response and dismissal
Alexa responds verbally, shows the NowPlaying Display Card, and plays the requested media. The customer can control the media via voice commands or GUI. The Card updates with each now song.
If the user:
-
Multitasks with the remote, both the Card and audio dismiss.
-
Pauses or stops the music via voice or the button, then the audio stops and the Card remains. The Card should auto-dismiss after one minute of inactivity.
-
Activates Alexa again, the music attenuates, and voice chrome reappears awaiting the next command.
Additional interaction scenarios are described in the Interruption Scenarios section.

Controls-Only Template
There may be instances when no metadata is returned from a NowPlaying request. In this instance, use the Controls-Only Template, which includes a minimized set of visuals.
Note: For certain Music Service Providers, the PlayerInfo directive is sent after the PlaybackStarted Event. In these cases, we recommend adding logic to wait 2 seconds for the PlayerInfo directive. If metadata is not returned after this time, display the Controls-Only Template.

Transitions
Transitions should be quick (< 1 sec) and employ easing to create a smooth feel. Display Cards enter from the right for partial-screen Cards, and fade in for full-screen Cards. The Card enters first, followed by the content fading in. To account for latency, a background placeholder box should appear in place of an image, which transitions to the fully loaded image when it arrives.
Cards exit the opposite way they came in. The content fades out first and then the Card removes. Partial-screen Cards slide off to the right and full-screen cards fade out.

Interruption Scenarios
Card to Card

Step 1: Utterance1
At Utterance1, voice chrome overlays the existing screen.
Step 2: TTS1 + GUI1
Alexa responds.
Step 3: Utterance 2 (Interruption)
When the customer interrupts Alexa (via tap or wake word), Alexa stops speaking and voice chrome overlays the existing card.
Step 4: TTS2 + GUI2
Alexa responds to utterance2 via voice and replaces the old card with a new one. This card dismisses according to regular dismissal rules.
NowPlaying to Card

Step 1: Utterance1
At Utterance1, voice chrome overlays the existing screen.
Step 2: TTS1 + GUI1
Alexa responds. Music plays.
Step 3: Utterance 2 (Interruption)
When the customer interrupts Alexa (via tap or wake word), the music attenuates and voice chrome overlays the nowPlaying GUI.
Step 4: TTS2 + GUI2
If the utterance is understood and a card is required, Alexa responds to the utterance via voice and a new card. Once the TTS completes, the music returns to the regular volume. The card dismisses according to regular dismissal rules, except that when dismissed, the customer returns to the nowPlaying card.
If the song changes during this time, when returning the nowPlaying GUI should reflect the new song.
