Viewers and players

Viewers are used for displaying read-only data. Examples of viewers are SMS, e-mail,

and image viewers.

To edit or create new data, the user starts an editor; the viewer may offer an option

for starting an editor.

When a piece of read-only data is presented, no focus is needed, as the user does not

need to access any individual object within the data – it is only necessary to be able

to go through the data. We can imagine the data projected onto a virtual strip of

paper that the user can move within the viewing window. There is no need to point

at a specific part within the data, but a viewer may be able to zoom in and out.

Text viewers should in general follow these guidelines:

Text is wrapped according to the width of the viewing pane. There should be no

need to scroll sideways while reading the text.

Up and down scrolling should proceed page by page. A press of scroll down key

displays the next screenful of text. (Note that in editors, text is scrolled line by

line.)

A still image viewer is a tool optimized for viewing photographs or other images. A

dedicated image viewer may offer features like zooming and scrolling, full screen

viewing, and adjustments of image parameters like brightness and contrast.

By default, the image should initially be scaled so that it fills the available screen

area.

Viewing functions are available in the viewer's menu of options. However, the

numeric keypad may also be used to control some of the functions – this allows

quick access to frequently used functions, such as zooming.
