It is a first prototype. Some later additions are not shown. For example i added basic handwrite recognition. So in a way you could select any equipment/command by just writing it.

Thank you all for the comments.

To come back to habits, the Bikkel consept goes in a way back to the past. The old fashioned volume control was just a dial. In a way i bring the dial back with the only difference that it is now made remote. This characteristic lowers the learning curve. 

I am not a manufacturer so i try to sell the idea as an invention to an established company.

I do particularly like that part of the idea. B&O tried something similar with the MCP5500-7000 and it's great in principle, but in practice the volume just doesn't follow the ring well enough, probably because the two-way communication reserves too much of the airspace.

Good luck with the project!
