Thanks Jan for the detailed answer.
I think it's great that you have already tested my proposal. I wonder why it should be more disturbing than helpful. I believe you. Unfortunately I can't test it myself.
I started flying simulator with Mircosoft FS4, but the visual problems started with the introduction of the 3D cockpit. Since then no really good solutions have been found. I'll say this for myself, because there are users who get along wonderfully with Track IR, while I don't like using the product. That is also the reason why I don't use your Eye-Tracker solution, because it is not based on eye-tracking but on head-tracking.
I tried to understand how you control the view and tried it again. It's true that you can pan the view very fast with the mouse and with the flywheel of the mouse I also zoomed in very fast, but I can't get the target object to be in the middle of the screen. Then I still have to correct the viewing orientation again.
My tests showed that the right mouse button works exactly like the left mouse button except that you can only use levers and not buttons and switches. However, when the cursor is over a switch, you cannot pan. I do not understand the sense of this behaviour. Wouldn't it be a good solution, if the right mouse button can only be used for panning and thus an accidental operation of buttons is not possible?
I can't imagine that my mind is irritated and gets sick when I select the target object with the right mouse button by clicking or double-clicking the target object and it is zoomed in with a short camera movement. As long as exactly happen what the mind expects, you actually don't get sick. I still remember the EZdok add-on. With one keystroke the camera pans to the desired destination. Because of the short camera movement this was very pleasant. It is only important to use very short acceleration and braking phases.
What do you mean by "advanced camera view"? You can switch through several views in the cockpit, but on the one hand there are no useful views (e.g. to control the radio) and on the other hand it takes too long.
IPACS does a good job. Thank you very much for that.
