Used on movies for audio narration for people with seeing disablities and to read out the subtitles for people with dyslexia that have problem reading them enough fast.
You first select what movie you want to see, i.e. in what room it is shown. After that you can select if you want to listen to the adio narration or if you want to hear the subscripts read. Its possible to select both at the same time.
The app can only be used when you are at the movietheater and connected to the local WiFi and over that to the server connected to the cinemaserver.
