USER INTERFACE ISSUES
The Browser Display
The Ericsson R380 display is a grey scale black and white touchscreen with a resolution of
360x120 pixels with 0.23 pitch. This means an active screen size of almost 83x28mm.
The browser display has three sections: the Browser Area, the Card Title bar at the top, and the
Toolbar to the right.
Browser Area
The Browser area is where the card content is presented to the user. The size of the area is
310x100 pixels. This includes a top margin of 2 pixels and a left and right margin of 3 pixels
each, which reduces the size of the usable area.
If a card content is too extensive to be visible in full, only the beginning of the card will be
visible when first displayed. In this case a vertical scroll bar appears to the right in the browser
area. The scroll bar reduces the browser area width by 16 pixels.
Since the browser does not have a horizontal scroll bar, all text is wrapped.
Graphical components, text and images are displayed in the browser area starting in the upper
left-hand corner and shown in the same order as they appear in the WML code.
Card Title Bar
The Title bar shows which card is presently being displayed and also the cards that have been
browsed through previously. If there are more cards being browsed through than can fit into the
Title bar, only the most recent titles are displayed.
This is a good reason to keep card titles short and meaningful.
