Here is the situation. You are going to do an important presentation in an international conference. You have made your presentation slides, it’s like the greatest presentation in the universe. You made the presentation using the latest version of Microsoft PowerPoint or OpenOffice.org Impress. You double checked your presentation and laptop right before you’re doing your presentation. Suddenly, out of nowhere, your laptop crash, error, bsod, or anything. You have no choice, you transfered your slides file to another computer that can do presentation. Unfortunately, the computer didn’t have the program that can open your slides. The computer has the older version of PowerPoint that couldn’t open your slides. Or maybe the computer using another operating system that your presentation program didn’t support. You’re panic and can’t think clearly. Everything went dark and suddenly you passed out.
Actually, this kind of situation can happens anytime. Even myself sometimes meet this situation in my campus life. It makes me think, what is wrong with the presentation software? Can we do something about it? Are there any solutions to this problem?
What’s wrong with presentation program?
On the situation mentioned above, the problem is about the compatibility among presentation program. Every presentation program has their own file format. Even if another presentation program could open the file, the slides presentation still will be differs from the original presentation we created. The compatibility among presentation program is very low. I know that the developers are working hard on it, I thank them. But it’s really really hard to make the presentation look exactly the same as in the origin program creator.
There are some solutions to this compatibility problem. Why don’t we use a presentation program that available anywhere without installing? I’m talking about the applications in the clouds. There are some nifty web-based presentation application on the Internet, like Google Docs or Docs for Facebook. With just a browser, you can create, share, and present the slides with these applications. Another alternative: SlideShare. You can create your slides with your favorite application. Then you just need to upload it to SlideShare. You can share and present the slides as the other web-based application I mentioned earlier.
Unfortunately, these web applications have their own limitation: you must connect to the Internet in order to use it. Maybe you’ll say, “Hey, that’s not a problem at all. We have a great connection that we can proud of“. Yeah, maybe you’re right. You have the best Internet connection in the whole world. But sometimes network can have their own problems too, especially when there are too many devices involved. When we couldn’t connect to the Internet, we’re done for.
HTML as a presentation program’s alternative?
In this Internet era, every computer always have at least a web browser. The browser can display HTML response from the web server. Maybe there are some differences on how one browser display a web page, but a lot of browsers now is already following web standards. The browser doesn’t need to be online to open a HTML file. What if we use HTML to create our presentation?
The impact of HTML5
So, why we are not using HTML5 for slides presentation? The answer is, some people already created an example presentation using HTML5. It shows us that HTML5 is quite promising as an alternative to presentation program. Now we can just wait for it being standardized. Meanwhile, let’s learn HTML5 to create presentation!
