There does not seem to be any one standard with the placement of buttons for windows and pages. According to the 'Apple Human Interface Guidelines' and the 'Windows User Experience Interaction Guidelines' , Windoze and Apple right-justify buttons on dialog windows. However their order is reversed. For Apple, the 'action button' is the right-most button. For Win, the 'commit' button is left-most. And to make matters less consistent, I see buttons left-aligned on web pages.
I suppose right-alignment makes more sense for left-to-right reading languages. This also is consistent with the F-pattern that people read pages. However, are buttons to the right of the page closer in proximity to right-handed users?
The impetus for this thought (or crisis) is that I am designing UIs with buttons left-aligned. I am left handed (using a left-handed mouse). Is this a better experience for me because the buttons are closer to the left of the screen? Would my right-handed users feel that right-aligned elements are closer to their mouse placements? Does left or right handedness effect cursor placements?
Please weigh in and let me know if you have had experience, researched or insight that might lead to a consensus?
