# UserIdleProcessor

> A processor that monitors user inactivity and triggers callbacks after specified timeout periods

<Warning>
  DEPRECATED: UserIdleProcessor has been deprecated. Use `user_idle_timeout`
  parameter when creating your aggregator, see [Detecting Idle
  Users](/pipecat/fundamentals/detecting-user-idle) for details.
</Warning>

The `UserIdleProcessor` is a specialized frame processor that monitors user activity in a conversation and executes callbacks when the user becomes idle. It's particularly useful for maintaining engagement by detecting periods of user inactivity and providing escalating responses to inactivity.

## Constructor Parameters

<ParamField path="callback" type="Union[BasicCallback, RetryCallback]" required>
  An async function that will be called when user inactivity is detected. Can be
  either:

  * Basic callback: `async def(processor: UserIdleProcessor) -> None`

  * Retry callback: `async def(processor: UserIdleProcessor, retry_count: int) ->
    bool` where returning `False` stops idle monitoring
</ParamField>

<ParamField path="timeout" type="float" required>
  The number of seconds to wait before considering the user idle.
</ParamField>

## Behavior

The processor starts monitoring for inactivity only after the first conversation activity (either `UserStartedSpeakingFrame` or `BotSpeakingFrame`). It manages idle state based on the following rules:

* Resets idle timer when user starts or stops speaking
* Pauses idle monitoring while user is speaking
* Resets idle timer when bot is speaking
* Stops monitoring on conversation end or cancellation
* Manages a retry count for the retry callback
* Stops monitoring when retry callback returns `False`

## Properties

<ParamField path="retry_count" type="int">
  The current number of retry attempts made to engage the user.
</ParamField>

## Example Implementations

Here are two example showing how to use the `UserIdleProcessor`: one with the basic callback and one with the retry callback:

    # Create the processor
    user_idle = UserIdleProcessor(callback=handle_user_idle, timeout=5.0)

    # Add to pipeline
    pipeline = Pipeline(
        [
            transport.input(),
            user_idle,  # Add the processor to monitor user activity

            # ... rest of pipeline
        ]
    )
    ```
  </Tab>
</Tabs>

## Frame Handling

The processor handles the following frame types:

* `UserStartedSpeakingFrame`: Marks user as active, resets idle timer and retry count
* `UserStoppedSpeakingFrame`: Starts idle monitoring
* `BotSpeakingFrame`: Resets idle timer
* `EndFrame` / `CancelFrame`: Stops idle monitoring

## Notes

* The idle callback won't be triggered while the user or bot is actively speaking
* The processor automatically cleans up its resources when the pipeline ends
* Basic callbacks are supported for backward compatibility
