Digital Presentation Class 9 Notes

To effectively convey knowledge to an audience, you must possess presentation. Presenting effectively is a highly sought-after ability in practically every industry today. Using a computer-generated presentation has a variety of benefits.

A presentation includes

  • Regular text
  • Lists items
  • Table
  • Graphics elements
  • Sound and Video
  • Animation

Characteristics of a good quality presentation

Number of lines – Try to fit 5 to 8 lines on a single page or slide. A paragraph or more of lines may require extra time to read since the font size may get too small.

Font-size – You must consider the audience’s distance from the screen and the size of the room while planning your presentation. In light of this, the font size of the presentation’s texts may be chosen.

Correct use of grammar and language – Your presentation’s syntax and terminology should be accurate since if you make a mistake, it will be repeated by the audience as a whole.

Inserting images, drawings, tables or graphs – Aim to keep each slide to no more than two graphics (pictures, illustrations, tables, or charts). If you include too many graphics, your audience will become confused.

Use of colours – Use different fonts, bold characters, and dark colours to draw attention to particular areas. Use dark colours for typefaces and light or silent backgrounds. Pay close attention to how the colours in the foreground and backdrop contrast.

Animation and videos – A slide should not contain more than one animation or video. The audience can become confused if more than one is used since the sounds will overlap.

Pay attention to target group – Pay close attention to the needs of the intended audience when crafting the presentation. Concentrate on the substance and arrange the items in a logical order that will draw the audience’s attention away from the goals.
