We have been experimenting with using a Raspberry Pi low power computing device to display building directory information. The software for these full HD directories has been developed in-house which provides for the display of tenant information, corporate video presentation. Along with brand information, these directories also provide contextual information in the form of weather and time widgets. Needless to say that all of this can be customised for your brand and needs.
The complete CMS is resident in the cloud and information can be pushed remotely to all terminals.
We are currently experimenting with integrating computer vision based interactions to these information directories.
