Wow, the more I think about it, I realize there are more disadvantages of using slides. Here are two more:
- Slides take out the human touch in presentations. Although people don’t realize it, the human touch is very important in effective communication. Tone, body language, gestures all make up a very significant part of the overall message that we deliver. With a big electronic display near the speaker, the audience gets distracted from the non-verbal cues that the speaker delivers. A lot of the message is diluted or completely lost.
- Slides can tend to waste everyone’s time. The presenter wastes time putting together slides which, instead of making the presentation effective, actually reduces the effectiveness. The audience, instead of focussing on the speaker, focusses on the slides and loses the main message.
