A presentation aid is anything that supports the spoken message through another sense — mostly sight, sometimes touch or hearing. Aids do three things words alone do poorly: they make the abstract concrete, they show relations and amounts at a glance, and they give the audience a second channel to remember with. Textbooks differ in how they count them; the six-way grouping below is a common one in public-speaking courses.
The six types at a glance
| Type | What it is | Best for | Example |
|---|---|---|---|
| 1. Objects and models | The real thing, or a scaled version of it | Showing size, texture, how something works | A prototype passed around; a model of a molecule |
| 2. Photographs and pictures | Images of real people, places and things | Emotion, evidence, recognition | A photo of the damaged bridge |
| 3. Diagrams and drawings | Simplified drawings of parts, processes or relations | Structure, processes, how things connect | A labelled diagram of a flower |
| 4. Charts and graphs | Visual representations of numbers | Trends, comparisons, shares | A bar chart of yields with and without bees |
| 5. Video and audio | Moving pictures and recorded sound | Motion, voices, events | Thirty seconds of a bee visiting blossoms |
| 6. Handouts | Printed or digital material people keep | Detail, references, follow-up | A one-page summary with sources |
Slides are usually not counted as a seventh type: they are the medium that carries types 2 to 5 to the screen. Whiteboards and flip charts are a medium too — they let you draw diagrams live.
1. Objects and models
Nothing beats the real thing for attention. A product sample, a tool, a piece of material: people want to see it, touch it, pass it on. Models stand in where the object is too big, too small or too dangerous — a building, a cell, an engine. Use objects when size, feel or mechanism matters. Keep them out of sight until you need them, and do not pass them around while you talk about something else: the audience will follow the object, not you.
2. Photographs and pictures
Photos prove and move. A photo of the actual site, the actual product or the actual people makes a claim credible and a story personal. Use large, high-quality pictures, one per slide where possible, and choose real ones over generic stock. Name the source when a picture is not yours.
3. Diagrams and drawings
A diagram leaves out everything but the structure: the parts of a flower, the flow of an order, the layout of a factory. That simplification is the point — a photo shows everything, a diagram shows what matters. Label parts directly and build complex diagrams step by step. Our guides to infographics and process flows show how to draw them in PowerPoint.
4. Charts and graphs
Numbers spoken aloud vanish; numbers shown as a chart stay. A bar chart compares, a line chart shows change over time, a pie shows a share of a whole. Each chart should make one point, written as its title, with the important bar or line highlighted. Read our guide to presenting data for how to choose and clean charts.
5. Video and audio
Video shows what still pictures cannot: movement, process, a voice, an event as it happened. Keep clips short (under a minute in most talks), introduce them (“Watch how the bee moves from flower to flower”), and test sound and playback on the room’s equipment. Audio alone — a customer’s voice message, a sound sample — can be surprisingly powerful with a still image.
Add a short clip to a slidePowerPoint (Windows and Mac)
Insert the video
Choose Insert → Video → This Device (Mac: Insert → Video → Movie from File) and pick the clip.
Insert → Video → This Device Trim it
Select the video and choose Playback → Trim Video. Drag the green and red markers to keep only the part you need.
Playback → Trim Video Set how it starts
Under Playback → Start choose When Clicked On or Automatically, and tick Play Full Screen for detail.
6. Handouts
Handouts carry what the audience should keep: details, references, figures to check later, the next steps. Give them out at the end unless people need them during the talk — otherwise they read instead of listening. A one-page summary usually beats printed slides. In PowerPoint, File → Print with 3 Slides per page leaves lines for notes; File → Export → Create Handouts (Windows) sends slides and notes to Word for a custom handout.
Rules for every kind of aid
- Purpose: every aid must help a specific point. If you cannot say which, leave it out.
- Visibility: large enough for the back row. Test from the furthest seat.
- Simplicity: one idea per aid; remove decoration.
- Timing: show it when you talk about it, remove it after.
- Talk to the audience, not the aid: glance at the screen, then face the room.
- Backup: a PDF of the slides, the video file locally, a spare cable.
How presentation aids reduce apprehension
Speaking anxiety — communication apprehension — is common, and well-prepared aids ease it in several ways:
- They shift attention. While the audience looks at a picture or a chart, the speaker is not the only thing in view.
- They structure the talk. Each slide or object is a cue for what comes next, so the fear of going blank shrinks.
- They give the hands something to do. Holding an object or a clicker, pointing at a diagram — movement with purpose replaces nervous movement.
- They build confidence through preparation. Making the aids is rehearsal: by the time they are finished, you know the content.
- They carry the facts. Numbers on a chart do not have to be remembered; the speaker can explain instead of recite.
The flip side: aids that fail — a broken video, an unreadable slide — raise anxiety. Test them in the room beforehand, and plan what you will say if one does not work.
Choosing the right aid for each point
Go through your outline point by point and ask what the audience needs to understand it. The answer usually points to one type:
| If the point is about … | Use |
|---|---|
| what something looks or feels like | An object, a model or a photograph |
| how parts relate or a process runs | A diagram |
| how much, how many, how it changed | A chart or graph |
| how something moves or sounds | A short video or audio clip |
| details to check later | A handout |
| an idea or a feeling | A single photograph, or no aid at all |
Not every point needs an aid. A personal story often works best with a black screen and your voice alone; in PowerPoint, press B during the slide show to black the screen and again to bring it back.
Designs for this kind of deck
Every design brings its own colours, fonts and layouts to the whole deck.
Visual aids made from a sentence
ExpertSlides makes the slide-based aids for you. Describe your talk — “a class presentation on how bees pollinate crops” — choose a design, and the AI builds a deck with pictures in the frames (generated for the topic, or your own uploads), diagrams such as processes and cycles, charts from figures you give it, and short texts that support rather than repeat what you say. Attach your own notes, a paper or a spreadsheet, and the slides are built from them.
For the audience’s part, interactive elements (Pro and Business) add quizzes, polls and flip cards to a deck — a quick check of what the class learned works as an aid of its own. Speaker notes under each slide hold your cues, and Presenter view shows them only to you.
More help for the talk itself: how to start and end a presentation and presenting data. See how the AI presentation maker works, or browse the Design Templates.
Questions, answered
What are the six types of visual aids?
A common grouping is objects and models, photographs and pictures, diagrams and drawings, charts and graphs, video and audio, and handouts. Slides and whiteboards are the media that carry several of them.
How can presentation aids reduce apprehension?
They shift attention away from the speaker, act as cues for what comes next, give the hands a purpose, build confidence through preparation and carry facts the speaker would otherwise have to memorise.
When should I give out handouts?
Usually at the end, so the audience listens instead of reading. Hand them out earlier only when people need them during the talk, for example to follow figures.
What makes a good visual aid?
It serves one specific point, is large enough for the back row, is simple, appears when you talk about it and works reliably on the equipment in the room.
Can ExpertSlides create visual aids?
Yes. From a sentence or your documents it builds slides with pictures, diagrams and charts in a design you choose; on Pro and Business you add quizzes and polls for the audience from the Insert tab.
