There is. In fact there's a whole suite of products out there serving it. At the base level you have DIY solutions (small LCD's, e-ink etc) which are loads of fun to build and can work quite nicely for some scenarios. Another option that a lot of buildings are starting to use is iOS / Android apps along with a device in a wall mount (https://eventboard.io/ https://eventboard.io/ et al). Cheap (ish), easily replaceable and upgradeable hardware and apps that are quite affordable. From here you then move into more dedicated devices which also provide some deeper integration with the environment. Traditionally this has something that has been handled by the AV world with products such as AMX's (http://amx.com/ http://amx.com/) RMS or Crestron's (http://www.crestron.com/ http://www.crestron.com/) RoomView, however there's a bunch of other really exciting players around to like Condeco (http://www.condecosoftware.com/ http://www.condecosoftware.com/) which merit some consideration. Regardless of who's providing it, its at this level the tech starts to getting a little more exciting. Generally you begin to tie in with sensors (PIR, seat pressure, signal presence on laptop input etc) inside the room to provide analytics on occupancy, auto cancel meetings when there's a no show, integrate with NFC for handling access control or user auth etc. If you coming from the AV side the rest of the room can also start to interact with that booking information to (for example, parsing meeting info for video / teleconference details etc).
