Customize Multimodal Devices for Alexa Smart Properties


In Alexa Smart Properties, you can complement the voice experience with visual content rendered on Alexa-enabled multimodal devices. Take advantage of the home screen to share details of the property, enable service ordering with voice or tap, and inform guests about events, updates, and skills.

You can add visuals to your property skill that Alexa displays when the guest interacts with a multimodal device by voice or tap. For example, when a guest asks, "Alexa, what time is breakfast?" you can display the hours, location, and breakfast menu. And, you can add visuals that Alexa displays when the guest isn't interacting with the device. For example, add images and visual messages to inform guests about upcoming events or the location of places on the property.

Follow these guidelines to send visuals from your property skill or property management application.

Supported devices

You can use the following multimodal Amazon Echo devices with Alexa Smart Properties:

  • Amazon Echo Show 5 (1st, 2nd, 3rd Generation)
  • Amazon Echo Show 8 (1st, 2nd, 3rd Generation)
  • Amazon Echo Show 15
  • Amazon Echo Pop

Recommendations

If you have multimodal devices on your property, Amazon recommends that you customize the home screen with the following visuals:

  • Send a visual response with each voice response from your property skill by using Alexa Presentation Language (APL).
  • Make sure that you define the device address correctly to enable Alexa to display the default weather card based on the location of the property. To update the address of an Alexa-enabled device, use the POST address setting API.
  • Provide at least seven proactive suggestions to display when guests aren't interacting with the device. Alexa displays each suggestion in a rotating fashion. The suggestions should include the following information:
    • Three suggestions for Alexa features, such as how to change volume.
    • Four suggestions for property features, such as how to connect to Wi-Fi or restaurant hours.
  • Use persistent visual alerts to display visual information that stays on the device.

Add visual responses from your skill

You can complement the voice responses from your property skill with visual responses that give more information, let the guest tap to select options, display images of the property, and more. For example, if the guest asks when the restaurant opens, your skill can give the answer with voice, and also display the restaurant hours for the day.

You can send visual responses from your skill by using APL, a responsive layout language that lets you build visuals to render on Alexa-enabled multimodal devices. To create visual responses with less effort, you can use the APL responsive components and templates instead of building your own layouts. With responsive components and templates, you choose the template and populate the data that you want to display. For details about how to add visual responses to your skill code, see Add APL Support to Your Skill.

The following table shows recommended APL templates suited for property skills.

APL template Example uses Sample utterances

Headline

Use to display a short, centered message with a background image, such as the property welcome screen.

"Alexa, open property skill name."

Image list

Use to display a scrolling list of images and text, such as the following responses:

  • List of dishes and drinks available at the restaurant.
  • List of services available on the property.
  • Search results.

"Alexa, recommend a place to eat."

Text list

Use to display a scrolling list of test-based items, with an optional header and background image, such as the menu items. Use this template when you don't have images for each item on the list.

"Alexa, what's for breakfast?"

Detail

Use to display text and an image to present structured information about a service of a property, such as service name, operating hours, location, and description.

"Alexa, is the gift shop open?"

Karaoke

Use this template when none of the other templates apply, usually for long-form text of more than two lines that scrolls automatically. You can display the same text that Alexa speaks on the screen.

"Alexa, how do I connect to Wi-Fi?"

Send proactive suggestions

You can use proactive suggestions to display visual content on Alexa-enabled multimodal devices to inform guests about your property, such as events, services, and amenities. Alexa renders these suggestions as cards on the home screen. When not responding to guest queries, Alexa rotates through the cards and displays the most recent suggestion first.

Customize the visual content for your property and send the suggestions on a time schedule. This content should be a mix of Alexa-submitted cards that tell the guest how to use Alexa features and developer-submitted cards that display information about the property. Proactive suggestions are great for content that isn't urgent, such as property information and events, weather, and news. Also, display information that's helpful to the guest, such as how to connect their mobile device to Alexa or how to connect to the property Wi-Fi.

To add a card to the home screen rotation, use the Proactive Suggestion REST API to create a campaign for a list of units. For each campaign, include the content to display on the screen, such as title, body, and background URL. You create one campaign for each suggestion that you send.

The following example shows a card that explains how to set up a timer.

Send persistent visual alerts

Persistent visual alerts are similar to proactive suggestions except the card stays on the screen until the expiration time or the guest dismisses the alert. Use persistent visual alerts for upcoming events, appointments, and other information that's important for the guest to see. You can set a separate alert for every booking or appointment that the guest makes by voice or tap.

To publish persistent visual alerts, use the Notifications API and include the content to display, along with an expiration time.

The following example shows a visual alert to remind the guest to take a walk.

Multimodal device FAQ

The following frequently asked questions (FAQ) answer common questions about customizing Alexa-enabled multimodal devices.

Q: What's the maximum number of cards that I can display?
You can send any number of proactive suggestions, but the maximum number of cards that Alexa can display is 20. Alexa displays the first 20 cards based on creation date, from the newest to the oldest.
Q: What percentage of time does Alexa show proactive suggestions?
Alexa displays cards at a 4:1 ratio of developer-submitted cards to Alexa-submitted cards.
Q: What's the size limit for background images?
The maximum image size is 400 KB in alerts.
Q: What formats does Alexa support for background images?
Alexa supports images in alerts in JPG image format.
Q: How do I specify images that aren't the same size or aspect ratio as the viewport of the device?
Images in persistent visual alerts are scaled up or down to fit the viewport size.
Q: How do visual alerts and proactive suggestions work with screen saving mode?
When a persistent visual alert is displayed, the device shouldn't go into screen saving mode. Proactive suggestions don't impact screen saving mode.
Q: How many suggestions can I add to a campaign?
You can add one suggestion per campaign. If you want Alexa to display more than one card, you create one campaign for each suggestion.
Q: Are title and body required properties for visual alerts and proactive suggestions?
Yes, the interface requires both properties.

No. You can specify any end date.
Q: How soon does the card display after the Proactive Suggestion REST API request?
Usually, Alexa displays the on-screen alert within two hours of receiving the request. If the guest power-cycles the device, the device flushes the current rotation and displays the latest suggestion.
Q: How soon does the alert display after the Notifications REST API request?
Usually, Alexa displays the on-screen alert within five minutes of receiving the request.
