Push-To-Talk over WebRTC

This project aims to build a push-to-talk (PTT) system on top of the WebRTC API. PTT is a communication technique that allows the user to talk to others through a microphone only when the user presses a button (or similar). The project will start with a literature study to determine how PTT can be implemented on top of WebRTC. After that, the focus will be on implementing a PTT system.

You will:

• Perform a literature review
• Implement a PTT system
• Conduct and evaluate a user study
• Design different interfaces for web and mobile
• Summarize your findings in a thesis and present them to an audience
• (Optional) co-writing a research paper

You need:

• Strong communication skills in english and german
• Good knowledge of web development (react & react native)
• (Optional) General knowledge of the WebRTC API and audio-codecs
