PAXboy - thanks for filling out the survey, as far as I'm concerned atypical customers are just as important to hear from as 'typical' ones.
I would intend to allow every passenger individual control over their own seat. The main concept driving the design is that each person will have their own space that cannot be intruded upon by others and is controllable only by that passenger.
I've found that the responses have remained pretty much the same after I posted links to the survey on aviation-centric websites. The only difference seems to be that when asked for their favorite airline, lots more people used the airline code rather than its name!
Another surprising result to the "would you fly more if seats were more comfortable" question - yes 31.58% no 42.11% (maybe 26.32%)
lomapaseo - thanks for the response. I have already considered the points you illustrate. This was the starting point of my design. The concept as it stands avoids 90% of the issue shown in your picture.
