AdViewer

Have you ever seen a TV monitor installed in public places, displaying multimedia advertisements? We have developed an Android-based device that controls these monitors.

The device divides the screen into several regions and allows various multimedia assets (like animations, video, images and even full web pages) to be displayed in these regions, changing them based on predefined schedule. Both the assets as well as the schedule can be managed remotely, so operators don't need to physically access the device to reconfigure it.

  • allows the user to contact bike station service staff,
  • works offline.
