Social And Ethical Issues Associated With Displaying

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

(Example1)
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:

  • storing
  • Page staping
  • duplex (back to back) printing
  • image enlargement and reduction
  • printing multiple pages on each sheet

(Example2)
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

(Example3)
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

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.
