Sorry I believe I am one day late in my comments. I hope they will still be considered. I had several questions on Section 6.3.1: 1) 6.3.1 - How do you determine the starting focus point (would it be the upper-left of Rejoice or the center)? Why is the starting point at the bottom-left corner of the "R"? 2) 6.3.1 - In phase 1, "At first, focusable objects are searched from the direction of navigation.". Please describe this search. Is it a binary space search (i.e. if moving in +ve y-direction, is it EVERY focusable element that has any portion of itself with a y-coordinate greater than or equal to the y-coordinate of the current focus point)? 3) 6.3.1 - All focusable entities in your example seem to be symmetrical, are you considering arbitrarily shaped entities like many "skinned" applications provide these days? What about "nested" entities? 4) 6.3.1 - does navigating the "focus point" put the focus point somewhere in the center of the entity or does it stop at the edge? Consider elements that are not necessarily symmetrical... 5) 6.3.1 - Consider http://www.codedread.com/images/gui.png. For the example on the left, what about when there are two candidates that are equal in terms of distance function? Which lower block does the UA choose? Does it matter? For the example on the right, if you start at one of the corner buttons, how do you ever navigate to the middle ring or smaller square? Is 8-way navigation required? NOTE that I don't necessarily expect you to solve all issues caused by inaccessible GUIs like those two examples, just want to ensure you are thinking of them. Thanks, Jeff Schiller
