A proposal for buttons usage and UI
Here is my proposal. It tries to fix up the following problems (IMHO):
- Need for a full-screen mode
- Usefulness of the news/books/docs/notes buttons
- Under-usage uf the "iRex" key
- Problems with long-presses being recognized wrongfully sometimes (esp. with the page turning "button")
The proposal has the following key aspects:
- Make the programs by default display in full-screen (as in the DR1000)
- Make the icon toolbar hidden by default when in a viewer, and only pop when up/down arrows are pressed
- Put the toolbar at le left side (covering all the height of the iliad), to be able to show more icons.
- Reserve the bottons on the left of the iliad for the viewer (not for the system).
- Reserve the buttons of news/books/docs/notes to be used as virtual desktops; so they can be used to switch between applications (4 applications open at maximum seems reasonable for the iliad).
- Use the "iRex button" as a system button, that displays a system menu with the battery state, date/time, Wifi/Lan connect/disconnect options, close application of current virtual desktop, portrait/landscape mode selection, etc.
Descriptions of the buttons
Left column, from top to bottom:
Back - When in sub-menus, goes back. Mapped to "Esc" key
Index/Bookmarks - Open document index and/or bookmarks for document
page button - prev/next page. Mapped to "Space"/"Backspace" keys.
Up - Opens the menu (left toolbar). When in menus, goes up
Enter - Select an option in the menus. When no menu, mapped to "Enter" key
Down - Opens the menu (left toolbar). When in menus, goes down.
news - go to the news virtual desktop (the app open there, if applicable)
books - go to the books virtual desktop (the app open there, if applicable)
docs - go to the docs virtual desktop (the app open there, if applicable)
notes - go to the books virtual desktop (the app open there, if applicable)
irex button - open the system menu
All of the above is for the case in which the iliad is in a viewer application. When in the ContentLister, the following differences apply:
- The left menu is always open, and instead of having icons, it has the filter options (more on the ContentLister in another post)
- The cursor in used for navigating both the left menu and the main content (the list of books, and programs)
I attach some very rough mock-ups.
P.D: Fot the viewers that want a standarized page number view, that could be put in the lower-right corner. But some viewers (html) have no notion of pages, so it must be optional.
P.D.2: The battery is not in the normal view. But in battery low condition the system would superimpose a "empty battery" indicator in the upper right corner (much like camcorders and digital photocamaras). This is easy to do technically using a shaped window.
