Hangout apps are regular web apps, running in a big window inside the Hangout UI. In addition to using shared-state APIs to give users real-time interactivity, you also have access to built-in Hangout features, such as:
- Initiate a group video chat with up to 10 people
- Control hangout microphones, cameras, speakers and volume levels
- Add sound effects and attach image overlays to faces
- Set UI elements such as the video feed, chat pane, and notifications
To get the ball rolling, we're introducing a new "Apps" pane in Google+ Hangouts, as well as some featured applications, including Aces Hangout, Cacoo, Scoot & Doodle, Slideshare, Clubhouse Challenge by Bravo, and Google Effects. We’re looking forward to seeing what you can dream up in the weeks and months ahead.
Follow the conversation on Google+, and happy building!
