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 2 - Side-scroll View
The basic feature of this design is that the photos are displayed horizontally by groups, and the user can scroll horizontally to view the pictures in that group. There are four main views for this design: albums view, friends view, search view, and search result view. The user uses the tabs at the top of the window to switch between the various views.
