I guess you are thinking about designing or at least looking into the theory behind control van lay outs user interface and that kind of thing.
The problem is every pilot has there own ideas about what is good and what is bad.
Cramped control vans, Poorly thoughtout control desks are the obvious problems however there is only a limited of space available and a lot of equipment to fit in. I would suggest if you are looking at this from a user interface perspective you should ask very specific questions and limit the responses in the form of a survey as there are a lot of different opinions on a lot of the various ROV systems. Classic example Are the verts better on a stick or a slider? If on a slider should sliding it away from you be up or down?
