The motivating example for |
358 |
|
|
359 |
|
The BuoyOING user interface is a focus+context hypertext interface |
360 |
|
that has been designed around the following three principles: |
361 |
|
|
362 |
|
- the user should always see all link targets |
363 |
|
("you should see where you can go") |
364 |
|
|
365 |
|
- the link transition should be fluidly animated |
366 |
|
("you should see where you do go") |
367 |
|
|
368 |
|
- the link transition and resulting view should make it obvious to the user how |
369 |
|
to go back, without an explicit back button |
370 |
|
("once you get there, you should see how you can get back"). |
371 |
|
This implies bidirectional links. |
372 |
|
|
373 |
|
The links are between specific locations |
374 |

In b) we are in the node F and see the relevant {\em fragment} of H, |

and in the c) and d) the view fluidly animates to the opposite case. |
