On-screen annotation: a small tool for clearer presentations
Showing a screen is not the same as explaining it.
When you share a presentation, it is easy to assume everyone is looking at the same detail. A dense slide, spreadsheet or interface gives an audience many places to look. On-screen annotation connects your words to a specific part of the image. The goal is not to add more information, but to make the important part easier to see.
Choose the right kind of emphasis
A box, an arrow and a laser pointer each serve a different purpose. A persistent outline keeps an area visible throughout an explanation. A brief pointer movement can guide attention during a transition. Too many simultaneous marks compete with each other, so remove old annotations when the discussion moves on.
Create a visual rhythm
Walk through a problem one step at a time. Pause after drawing, explain what the mark means, then continue. This lets the audience follow the reasoning as well as the answer. In remote lessons, allow for small screens, compression and connection delays before adding the next piece of information.
Test the workflow before presenting
Check that your operating system and sharing software display the annotation layer correctly. Try the pen, pointer and clear controls before the meeting starts. PenDesktop is being developed for these desktop explanation workflows. It has not launched; Windows and Mac store links will be added after release.
Choose the mark that matches the message
Use a pointer when attention only needs to move for a moment. Draw a box when a particular number, button or region matters. Use a short handwritten label to explain a relationship the screen does not make obvious. Different marks do different jobs; adding all three at once usually makes the screen harder to read.
Try it in a real explanation
- Open a document with one chart and decide which single conclusion you want the audience to take away.
- Point to the relevant series, then circle the one value that supports the conclusion.
- Pause before adding the next mark. Clear the screen when you move to a different question.
A useful test is whether someone joining late can tell what the current annotation refers to. If old circles and arrows are still competing for attention, clear them before continuing. Annotation should leave the underlying content legible, including at the smaller size used in a video call.
