The Interactions Protocol Playground web app allows users to interact with a Daily video room integrated with Tavus's backend for testing replica interactions. Specifically, it utilizes Tavus's Interactions Protocol. Here’s a breakdown of its components and interactions:

• Conversation ID Input: Users enter a Tavus conversation_id in the input box and press the "Join" button to initiate a session with that specific ID.
• Dynamic Updates: When a new conversation ID is entered, it updates all interaction text areas with the current ID.

• Each interaction button is associated with a specific event_type:

  • Echo: Triggers the conversation.echo event, where the replica speaks a predefined message. This is set in the echo-box text area.
  • Respond: Simulates a user’s spoken input, sending a message under the conversation.respond event as if the user had spoken in the room.
  • Interrupt: Initiates an conversation.interrupt event, signaling an interruption in the ongoing interaction.
  • Overwrite Context: This action updates the conversational context with new information, using the conversation.overwrite_llm_context event. This is useful for changing the replica’s understanding of the conversation.

• Message Execution: Each button has an executeCode function, parsing and validating the JSON in the respective text area. The callFrame.sendAppMessage() method then sends this data.

• App Message Listener: Upon joining a room, the callFrame listens for app-message events. These include all interactions and updates from Tavus or Daily, relayed in real-time.
• Log Handling: Each received message is parsed and appended to a log with a timestamp in [HH:MM:SS.MS AM/PM] format. Each entry includes:
  • Role: Indicates the role of the speaker (e.g., user, replica).
  • Speech: Content of the spoken text.
  • Visual Context: Any associated visual context data.
• Chronological Order: Log entries are ordered chronologically, refreshing to display the latest messages at the bottom.

This setup allows users to test various conversational interactions in a controlled environment, viewing real-time responses from the replica as well as logs of each exchange.
