Conversation menu anatomy

Selected State

The selected state is applied to an active or expired conversation item in the conversation menu when it is the most recently selected conversation. When within the conversation menu, tapping the “back icon” button in the panel header returns the user to the selected conversation.

Unselected State

The unselected state is applied to a conversation in the conversation menu when it is not the most recently selected conversation.

The conversation menu appears in the default variant when there are nine or fewer active conversations.

Full

The conversation menu appears in the full variant when there are ten active conversations.

When a user starts a new conversation and submits a query, the conversation is automatically titled “New Conversation” and saved in the active conversations section. Once Joule provides a response, the conversation title is automatically updated to reflect the query topic. This update is reflected in both the thread panel header and the conversation menu.

Creating a new conversation and then sending a query

Active conversations expire after a period of inactivity and are limited to set number of conversations at a time. Expired conversations are automatically deleted after a predefined duration. If the active conversations limit is reached, the “New Conversation” button in the conversation menu is disabled and the “New Conversation” option in the conversation panel header overflow menu is removed.

Conversation limit behavior in the conversation menu (left) and within a conversation (right)

Expired conversations are automatically deleted after a predefined duration. After opening an expired conversation, an error-handling pattern is displayed. The error-handling pattern blocks the input field, indicates that the conversation is expired, and provides a “New Conversation” button. If the active conversation limit is reached, the “New Conversation” button is disabled, and the error message prompts the user to delete an active conversation to create a new one.

The multi-threading pattern saves the user’s conversation history. If Joule is closed, the user returns to the last open selected conversation upon reopening Joule, regardless of whether the conversation is active or expired. If the last open screen was the conversation menu, the user returns to the selected conversation “behind” the menu. The user does not return to a conversation menu upon reopening Joule.

Reopening Joule after leaving off on the conversation menu

Tapping the menu icon button in a conversation panel header opens the conversation menu. Tapping the “back” icon button in the panel header returns the user to the conversation.

Opening the conversation menu from a conversation

Tapping the “expand/collapse” icon button in the active/expired conversation section header expands/collapses the active/expired conversation section. The active conversation section is expanded by default; this state resets when the user restarts Joule. The expired conversation section is collapsed by default; this state is persistent regardless of restarting Joule.
