Tools for Displaying


software for display
– interfaces for hardware display devices
– display features in applications packages, including:
- reporting
- formatting
- spacing
- merging
- tables
- charts
non-computer tools:
– traditional methods for displaying the different types of data

social and ethical issues associated with displaying
– communication skills of those presenting displays
– past, present and emerging trends in displays
– appropriate displays for a wide range of audiences, including:
- standards for display for the visually impaired
- displays suitable for young children

The key point to be learnt from this unit:

  • The role software plays in the display process
  • How shared data can inmprove the display of information

The user interface

The user interface allows users to control the operation of display and software

Usre interfaces are the printer layout features such as the this on figure 1 just on the left. Once the interface technology is installed into the computer and control values set the printer/photocopyier becomes a laser printer attached to the pc. Having computer interface technology allows user to access feture normally found on big and expencive office copiers.
Print options that become available are fetures such as:
*Page staping
*duplex (back to back) printing
*image enlargement and reduction
*printing multiple pages on each sheet

Userinterface setting for screen display. The interface allows greater control over the diplays such as setting and altering:

  • the screen resolution
  • the number of display colours
  • placement of hyperlinks directly onto the desktopscreen

Audio setting interfaces shown below for recording and playback hardwares. Allowing the user to control volume levles and sterio speaker balance.

Display application

Software applications have special display features that provide users control over how infomation is presented. features allow user to make changes to diplay format to improve the data presentation and automatically keep shared data.


Charts are one way of inmproving data presentation and make data easier to read for the user. Charts simplify confusing numerical data and present the same data in a simpler form showing relationships, trends and comparisons a glance. There so simple the most difficult part is selecting a suitable format for the job.

Dynamic data exchange

Dynamic data exchange is the exchange of data between different software applications. Dynamic data link stores the original document name in the destination document. Also storing the location and the formate of the shared data.

User need to share data such as:

  • Chart from spread sheet to word-processed report
  • Text file to appear as a vidio graphic

Most commonly shared throgh system clip boards. This means going having to manually switch between the t original destination to copy and past over and over unless a dynamic data link is set up.

Mail merge
Mial merge very important for it's covenience. Mail merging is used mostly in business or organisations which normally have large mailing lists.

Mail merge combines data from a datbase to onto a word processed letter. The end product of a mail merg is multiple copies of the one letter with personalised information for each recipient.

Mail merge combines data from two different documents. This can be a datbase of names and adresses with a word processed letter. One document will contain the personal details of each person on the mailing list. When the two documents merge the end result will be a personalise
letter for each person.
