We have two big screens with a size of 65 inches. With a special overlay we made touchscreens out of them. Both screens can be connected with any other device in the room with two Chromecast sticks. The devices just have to be in the “ExperienceLab” Wireless LAN.
With this technology every member of a conference can present his work without standing up and connecting their device with a cable. Additionally the Screens can be used to show external members during a videoconference.
