Electronic Presentation - Update ‘99

Why make Electronic Presentations?

For the following reasons:

I have been giving electronic presentations over the past few years. This means I prepare the presentation on my computer, arrive at the site and present the talk from my laptop computer.

 

Advantages

Disadvantages

You now have 10 new and even more frustrating problems, to replace the out of sync dual slide projector problems that we now have. The common problem is the projector not being able to scan at the high rates for some new laptops.

What equipment do I use?

I will tell you what has worked for me. There are many different companies for both the hardware and software.

 

Hardware

       

2 hard drives of 6 gig each. One mainly to hold pictures and videos, the other for the applications. This computer has the ADSL high speed modem for the internet

 

 

Software.

Win 98 with Microsoft office 2000. I have decided to throw in with the 'evil empire', and use all the Microsoft products. I author initially in word, and then can cut and paste:

The means that I only have to author once and can use this in multiple formats. All these programs work together.

I use PowerPoint, simply because it was the first and the easiest one that I learned.

Adobe PhotoShop. - to enhance and manipulate images from snappy, the Sony arthroscopy system and from the digital cameras.

Adobe premier for video editing

Light view Pro to view and catalogue, JPEG images

Image access pro from Dascorp to catalogue the images on the zip drive. It sets up a thumbnail at the beginning of the disc, so that you can find the image you want.

Textbridge Pro to scan text into electronic documents

The preparation

The hardest part is to acquire and archive the images and video. Once you have done that then the rest is a piece of cake.

Store all the digital images that you capture on a large hard drive or on a JAZ drive. Use image access pro to catalogue the images so that you can find them.

The digital camera captures all the x-rays, clinical photos etc. The Sony DKR captures the arthroscopy images.

The video capture card captures the video sequences. These are then edited in premier and stored as an .avi file.

I now store this on a separate computer, a server. This has 50 GIG of storage. When I am working on one of the other computers, I can go the the server over the LAN (network) and get an image or video clip and insert it into PowerPoint or into .html for the web page or CD presentation.

Don't wait until you have to make a presentation. Capture something every day and store it. You then build up your database, it will come in handy for some lecture.

Remember to start all authoring in word. Then you can move to the other programs. This is easy to do with the large monitor and split the programs vertically on the screen.

PowerPoint is very easy to use. I use the wizard to set up the storyboard. I then put my text into the slide. I add photos and video where indicated. All the work is done on the desktop and then transferred to the zip ( for storage and backup ), and then to the laptop. Once I finish with the presentation I remove it from the desktop and the laptop to free up my hard drive.

Remember the basic rules:

Instructions on PowerPoint

 

PowerPoint Lesson 1

View and File Menus

 

 

Opening Prompts

 

Text boxes

 

 

Formatting Text

 

 

Format Toolbar

Keep it simple. I would not appreciate seeing each line in a different color. Use font style and colour only to accent a very important point such as a column of numbers in a table or a key word. PowerPoint is a powerful tool and a lot of fun to play with however don’t loose sight of what you are trying to accomplish…transfer of information.

See a further discussion about the layout of slides at the end.

The Presentation

Up until recently this has been the most frustrating aspect. I have been able to make wonderful presentations on the computer, but can’t get them up on the big screen.

The North American Arthroscopy Association is committed to the concept of electronic presentation, and you will be able to come to the meeting with your presentation on a disc.

Make sure that you show up early, to test your system. If someone else uses the equipment ( video projector ) you may have to re boot your computer, so that the projector will recognize it. This takes time to get a large file up, 5+ minutes. This is better with more memory on a faster laptop.

Try to schedule your presentation first in the morning, or after a coffee break. This way you can have the presentation ready to go, without having to go back to the projector to change settings.

 

Projectors.

The hospital recently bought a Barko projector ( $25,000) for the auditorium. Finally we can see the presentation almost as clear as slides.

Around the hospital seminar rooms, I use a NEC LCD projector ( $12,000.) This is large, heavy ( 50#) and can be taken to various sites around the hospital. It works very well, with sharp clear images that are almost as good as slides. It is plug and play for both the Mac and PC. You can also plug in a video player. The resolution is only 800X600

We also have 5 Xerox projectors that are very portable to travel around the hospital.

This means that you have to set your screen resolution to 800X600. Some of the older LCD projectors such as the proxima will have to be set at 640X480 resolution. You can change the setting by a right mouse click on the desktop of windows 95, select properties, settings and change to the above. Sometimes you also have to change to CRT. Select properties, refresh and change to CRT from LCD.

These are the last minute adjustments that have to be made to be able to see a clear image. Usually the av. technicians are not that versed in the use of computers, so you are on your own.

 

VGA to NTSC scan converters.

This device allows you to present from your laptop to TV. For small groups up to 10 this is a reasonable way to present.

I have just bought a new one, TV superscan. This allows some adjustment to the image onscreen. Some of the converters cut off the bottom of the slide.

They still are not as clear as slides, but quite acceptable. The TV superscan is plug and play, very easy to set up. It does not require software when used with win95.

You lose some resolution compared to slides, but for small groups, it works quite well.

Most of the new laptops have a NTSC output and avoids the scanner problem. Some of the new laptops have an output to go directly to the TV. (NEC 6260)

 

LCD panel for overhead projectors

Forget about them, not bright enough.

 

Remote control for the laptop

I use the MindPath remote. They have a website at http://mindpath.com

This allows you to move up to 40 feet away from the laptop. The laptop has to be close to the video projector. That position may not be the best for you.

Remember - if you need slides or rental LCD projectors call -

Genigraphics 1 800 790-4001 You can modem your slides to them and they will fed ex them back to you the next day.

 

The Magic bag

These are the extras that I bring in my bag.

 

Problems

There are several problems that I have encountered doing electronic presentations.

The Mac and PC have different connections. If you have a Mac, better bring your own connecting cord. The long cords that run from the projector to the podium may not allow for a good electrical connection. Not much that you can do about that.

This is the commonest problem. My laptop is set at 1024X764 to work and view images. When you present you may have to change this to 800X600. ( see above )

 

Summary

The electronic presentation allows for lots of pizzazz. The downside is the expensive learning curve. Since many people have now been through this already, we should be able to get you up to speed with minimal frustration.

This is going to be the future of presentations at the Arthroscopy association, so you had better be there.
