Many people are not open to change they resist it. People tend to get comfortable at their workspace. So when there is change, how do they react?
How have people really reacted to the Office Ribbon bar?
This reminds me of the time when I was comparing the office 2003 with macromedia (then) adobe (now) flash interface in 2005 with a friend. We opened all the toolbars of office and noticed how they took up half the screen, I guess we weren’t the only ones to notice it 😛 We notice how neatly the Flash interface had provision to make certain parts visible and their accessibility.
I was working on an interface which had the navigation on the right, yes, that’s right the main navigation on the right side for the user (Fitts’ law is a model of human movement which predicts the time required to rapidly move to a target area, as a function of the distance to the target and the size of the target.), to make it easily accessible to the user. There was lots resistance to use it in my workplace but when macromedia (then, Adobe now) came out with Breeze with the navigation on the right, they were open to implementation of the interface on the right.
Now, Web 2.0 (example blogs) have their primary navigation on the right.
