# Feedback/Return Channels (Rückkanäle)

**Feedback Channels** (also referred to as **Return Channels** or **[[rueckkanaele]]**) refer to the communication paths used in a [[hybridveranstaltung]] to enable bidirectional interaction.

In a hybrid teaching scenario, these channels are critical to ensure that the session is not a one-way broadcast. They allow the instructor to communicate and receive input from:
1. **In-person participants**: Students physically present in the lecture hall or seminar room.
2. **Remote participants**: Students joined via video conferencing tools.

Effective feedback channels are essential for maintaining engagement and ensuring that remote students are integrated into the classroom discourse. Specifically, they allow remote participants to interact with both the instructor and the in-person audience.

## Implementation Methods

To effectively manage the return channel, particularly in the context of a [[hybrid-seminar]], the following techniques are recommended:

- **Text-Based Interaction**: Utilizing the built-in chat functions of software such as [[bigbluebutton]] or [[jitsi-meet]].
- **Audio Integration**: Routing the audio signal from the virtual conference room into the physical room's sound system.
- **Visual Integration**: Using a projector or a large display to show the remote participants' video feeds to the local audience, ensuring they are "present" in the room.
- **Hardware Separation**: Using a secondary computer dedicated to the internet stream to manage the return channel without interrupting the main presentation.
