We found this new hardware from Stream Deck to be incredibly useful and easy to use.
It is essentially a programmable LCD buttons ( 6 or 15 buttons available). It is popular among Video Streamers, however the Stream Deck can easily be used to as a Audio Video Controller Panel to streamline your services ( think creating Macros to run services at a touch). THe buttons are totally customizeable so you can create labels and icons easily.
There is also a Open Source project called COMPANION that allows you to integrate with Audio Video Presentation equipment.
For example , we have use the Stream Deck to build a nice Audio Video Matrix Controller to control the Octava Video Over IP Matrix Switch.
