視覺選取回應 (Dialogflow)

在 Dialogflow 中探索

按一下 [繼續],將回應範例匯入 Dialogflow。接著,請按照 部署及測試範例的步驟:

  1. 輸入虛擬服務專員名稱,並為範例建立新的 Dialogflow 代理程式。
  2. 代理程式匯入完畢後,按一下「Go to agent」
  3. 在主要導覽選單中,前往「Fulfillment」(執行要求)
  4. 啟用「Inline Editor」(內嵌編輯器),然後按一下 [Deploy] (部署)。編輯器包含範例 再也不是件繁重乏味的工作
  5. 在主要導覽選單中,前往「Integrations」(整合),然後按一下「Google」 Google 助理
  6. 在出現的互動視窗中,啟用「自動預覽變更」,然後按一下「測試」 以開啟動作模擬工具
  7. 在模擬工具中輸入 Talk to my test app 即可測試範例!

提供視覺選擇回應,希望使用者做出選擇 ,才能繼續執行動作。

視覺選擇回應可以顯示在純螢幕體驗中 結合音訊和螢幕元件的體驗

視覺選擇回應可包含以下元件:

或是參閱對話設計指南,瞭解 如何將這些視覺元素整合至動作中。

屬性

視覺選擇回應具有下列規定和選用 您可以設定下列屬性:

  • 支援具有 actions.capability.SCREEN_OUTPUT 功能的介面。
  • 視覺選取回應中的第一個項目必須是簡易回應
  • 最多一個簡單的回應。
  • 最多一個基本資訊卡、選項介面 (清單輪轉介面)。 或 StructuredResponse。(不能同時擁有基本卡片和選項 同時在介面中操作)。
  • 最多 8 個建議方塊
  • FinalResponse 不支援建議方塊。

以下各節將說明如何建立各種視覺選擇 回應。

清單

,瞭解如何調查及移除這項存取權。
圖 1.清單範例 (智慧型手機)

單選清單會向使用者顯示含有多個項目的垂直清單 並可讓使用者選取一個項目從清單中選取商品 會產生包含清單項目標題的使用者查詢 (即時通訊泡泡)。

具有以下項目的介面支援清單回應類型: actions.capability.SCREEN_OUTPUT 功能。

屬性

清單必須包含至少 2 個清單項目,最多 30 個。清單具有 屬性:

  • 清單標題 (選填)
    • 固定字型和字型大小
    • 僅限單行。(超過的字元會遭到截斷)。
    • 不支援純文字,例如 Markdown。
    • 如未指定標題,資訊卡高度會收合。
  • 清單項目
    • 標題
      • 固定字型和字型大小
      • 長度上限:1 行 (以刪節號截斷...)
      • 必要項目不得重複 (支援語音選項功能)
    • 說明 (選填)
      • 固定字型和字型大小
      • 長度上限:2 行 (以刪節號截斷...)
    • 圖片 (選用)
      • 大小:48x48 像素
  • 互動情形
    • 語音/簡訊
      • 使用者隨時可以說出或輸入項目標題,不必輕觸。
      • 必須針對可處理 actions_intent_OPTION事件。

指引

清單適用於區分選項的重要時機,或 使用者需要選擇需要一目了然的選項 例如「Peter」你是不是要跟 Peter Jons 還是 Peter Hans 說話?

建議你在清單下方加入建議方塊,方便使用者查看 引導或展開對話請勿重複顯示 將清單顯示為建議方塊這種情況下的方塊會用來 對話 (不適用於選取項目)。

請注意,在隨附的範例中,伴隨的 清單資訊卡是音訊的一部分 (TTS/SSML)。音訊輸出裝置 只包含第一個清單項目我們不建議讀取所有元素 確定要繼續嗎?

確保您的動作對使用者來說最重要的內容 清單頂端 (例如最熱門、最近購買或 最常談到的事)。清單一開始最多可顯示 10 個元素,但使用者 即可展開清單以顯示更多元素。清單中的項目數量 也可能隨著介面和時間而改變。

處理選取的項目

使用者選取某個商品時,系統會將選定項目的值做為 引數。在引數值中,您會取得key 已選取的項目:

Node.js

app.intent('List - OPTION', (conv, params, option) => {
  const SELECTED_ITEM_RESPONSES = {
    'SELECTION_KEY_ONE': 'You selected the first item',
    'SELECTION_KEY_GOOGLE_HOME': 'You selected the Google Home!',
    'SELECTION_KEY_GOOGLE_PIXEL': 'You selected the Google Pixel!',
  };
  conv.ask(SELECTED_ITEM_RESPONSES[option]);
  conv.ask('Which response would you like to see next?');
});

Java

@ForIntent("List - OPTION")
public ActionResponse listSelected(ActionRequest request) {
  ResponseBuilder responseBuilder = getResponseBuilder(request);
  String selectedItem = request.getSelectedOption();
  String response;

  if (selectedItem.equals("SELECTION_KEY_ONE")) {

  } else if (selectedItem.equals("SELECTION_KEY_GOOGLE_HOME")) {

  } else if (selectedItem.equals("SELECTION_KEY_GOOGLE_PIXEL")) {
    response = "You selected the Google Pixel!";
  } else {
    response = "You did not select a valid item";
  }
  return responseBuilder.add(response).add("Which response would you like to see next?").build();
}

圖 3.輪轉介面範例 (智慧型手機)

輪轉介面會橫向捲動畫面,讓使用者選取某個項目。比較 加入清單選擇器,就可以透過大型圖塊,呈現更豐富的內容。資訊方塊 構成輪轉介面的方法,與包含圖片的基本資訊卡類似。選取 系統會產生即時通訊泡泡,就像顯示回覆一樣 清單選取器。

屬性

輪轉介面回應類型具有下列規定和選用項目 您可以設定下列屬性:

  • 支援具有 actions.capability.SCREEN_OUTPUT 功能的介面。
  • 輪轉介面
    • 最多只能有十個圖塊。
    • 至少兩個圖塊。
    • 不支援純文字,例如 Markdown。
  • 輪轉介面圖塊
    • 圖片 (選用)
      • 圖片已強制調整為 128 dp 高 x 232 dp
      • 如果圖片的長寬比與圖片定界框不符 表示圖片置中,兩側皆有長條
      • 如果圖片連結損毀,系統會改用預留位置圖片
    • 標題 (必填)
      • 與基本文字資訊卡相同
      • 標題不得重複 (可支援語音選項功能)
    • 說明 (選填)
      • 格式選項與基本文字資訊卡相同
      • 最多 4 行
      • 不支援純文字,例如 Markdown。
  • 互動情形
    • 左右滑動:滑動輪轉介面即可顯示不同的資訊卡。
    • 輕觸資訊卡:輕觸項目即可產生含有相同內容的對話泡泡 做為元素標題
      • 必須針對可處理 actions_intent_OPTION 事件的觸控輸入意圖建立意圖。
    • 語音/鍵盤:使用資訊卡標題 (如有指定) 函式回覆 就像選取該項目一樣

指引

如果使用者能查看多種選項, 不需要比較名單 (和清單)。一般來說, 清單儲存至輪轉介面,因為系統在視覺上瀏覽清單內容 透過語音進行互動。

如果您想使用會連結至網頁的項目建立輪轉介面, 可以改為建立瀏覽輪轉介面

如要繼續操作,建議你在輪轉介面下方新增建議方塊 就能與會談。

建議不要在建議方塊內重複顯示清單中的選項。來自以下區塊的方塊: 此情境用於引導對話方向 (不適用於選取選項)。

如同清單,輪轉介面資訊卡隨附的即時通訊泡泡為 與音訊的子集 (TTS/SSML)這裡的音訊 (TTS/SSML) 整合了第一個 我們也強烈建議不要閱讀所有元素 選項。建議先提及第一個項目,並說明原因 例如最熱門、最近購買或最常購買 剛才談到的事)。

程式碼範例

處理選取的項目

使用者選取某個商品時,系統會將選定項目的值做為 引數。在引數值中,您會取得key 已選取的項目:

Node.js

app.intent('Carousel - OPTION', (conv, params, option) => {
  const SELECTED_ITEM_RESPONSES = {
    'SELECTION_KEY_ONE': 'You selected the first item',
    'SELECTION_KEY_GOOGLE_HOME': 'You selected the Google Home!',
    'SELECTION_KEY_GOOGLE_PIXEL': 'You selected the Google Pixel!',
  };
  conv.ask(SELECTED_ITEM_RESPONSES[option]);
  conv.ask('Which response would you like to see next?');
});

Java

@ForIntent("Carousel - OPTION")
public ActionResponse carouselSelected(ActionRequest request) {
  ResponseBuilder responseBuilder = getResponseBuilder(request);
  String selectedItem = request.getSelectedOption();
  String response;

  if (selectedItem.equals("SELECTION_KEY_ONE")) {
    response = "You selected the first item";
  } else if (selectedItem.equals("SELECTION_KEY_GOOGLE_HOME")) {
    response = "You selected the Google Home!";
  } else if (selectedItem.equals("SELECTION_KEY_GOOGLE_PIXEL")) {
    response = "You selected the Google Pixel!";
  } else {
    response = "You did not select a valid item";
  }
  return responseBuilder.add(response).add("Which response would you like to see next?").build();
}
