Using Powerpoint to Create Online Presentations
The easiest way to create a narrated presentation for publication on nanoHUB is to use Powerpoint. The Record Slide Show (found under menu Slide Show, see image to the right) is used. You should use either a lapel microphone or a headset microphone. See more on microphone selection below.
This form of presentation requires a linear progression through your slides, you can not jump backwards as it will cause any prior recording corresponding to the slides to be erased.

Good audio is an important component of an online presentation and microphone selection has a significant impact on the quality. You should use either a lapel microphone or a headset microphone and not use the built-in microphone provided with your PC. With the advent of Skype there are now a number of good USB microphones available that can be used. Here are a few models:
- Logitech HeadsetsBR
Important Powerpoint Techniques
- Slide Titles: Slide titles are important as they are used to generate a table of contents. A text box at the top of your slide doesn’t a title make. If the title does not appear in the outline summary (located to the left while in normal viewing mode), the slide is not properly titled. In the example shown to the right, slide 19 is not titled. If the title conflicts with the layout of the slide, use it anyway and position the title so it is off the slide. A good example of the use of titles is Alejandro Strachan’s lecture First Principles-based Atomistic and Mesoscale Modeling of Materials.
- Presentation: Remember to create your slides for presentation on a personal computer. Font size selection for screen projection also works well for computer screen presentation.
- Apple Macintosh/Windows PC Compatibility Issue: A inter-compatibility issues exists for Powerpoint presentations created on an Apple Mac and then moved to a PC. When viewing the presentation on a PC some images will appear blank with the error message “TIFF conversion error”. This results from adding an image to a slide by copy-paste instead of adding the picture from a file using Insert -> Photo -> From Picture File… To avoid this always insert pictures from a JPEG or TIFF file. This typical occurs when an image is copied from a website using copy-paste instead of saving the image from the website as a file and then inserting the picture from that file.
The following Powerpoint templates are provided for the convenience of our contributors, usage is not mandatory. Please feel free to adapt them to your specific needs.
Speaking Do’s and Don’ts
- Do not talk through the transition from one slide to the next. It’s a good time to pause for a moment and take a short breath.
- Do remember that the person viewing your presentation will not be able to see your hands, fingers, or laser pointer.
- Do remember that this technology requires a linear progression of your slides during the talk. Should you need to refer to a previous slide, please duplicate the slide in your presentation.
- Do remember when referring to an item on a slide to either articulate clearly what it is on the slide you are talking about, or make use of Powerpoint animations to highlight the area of discussion.
- Do remember to introduce yourself at the beginning of your presentation. Example: “Hello, my name is …, I am professor of …, etc., my background is ….”
- Do use a lapel microphone. Clean audio makes all the difference in the quality of one’s presentation. Wireless is recommended for lecture style presentations.
- Do be aware of the ambient noise that may be present when you are recording. Offices are notoriously noisy with fan noises and buzzes from lighting.
