Error prevention and correction: As noted above, it is rare for users to be able to make a serious error in PhotoBook. Navigation errors, however, may be common when the user is searching for a particular photo and has to look through several albums. While it is easy to correct this error by using the “Back” button, the other designs mentioned below make the error less likely and faster to recover from. Specifically, the user does not need to “open” albums in the Side-scroll design (Design 2), and thus will not open the wrong album by mistake. In design 3, opening an album is less of a commitment than in this design, since instead of being moved to an entirely separate page, some other albums remain visible when an album is opened, and an album can be closed by simply tapping anywhere outside the album.

Design 3 - Folders + Combination
This design presents a powerful combination between designs 1 and 2. Overall, we thought design 1 works very well for exploring, so this design uses a grid view similar to that used in design 1 to display albums. We thought design 2 works very well for searching, especially when the user is looking for a particular photo, so this design uses a side-scroll view for displaying search results. This design also uses a different metaphor for opening albums, and makes several other important changes, as explained next.
Albums/Friends View
On this interface, a grid of albums (or friends) is shown. Clicking on a photoset opens it in the same style that the iPad uses for folders on the home screen. Close the photoset by tapping outside of the opened portion.
