When Words Are Not Enough: Rich Media for Training and Documentation (Part 3)
(This three part post is the content of my presentation at DocTrain West on May 5, 2008 in Vancouver, BC. You can view the presentation here.)
Some Streaming Details
Steaming your rich media files has some hardware and software requirements. First you’ll need some way to create the file; your editing software will take care of this. media files are much larger than documents so you will require enough storage for the original footage and the finished edited version. Think hundreds of gigabytes or better, terabytes. To upload and download streamed media files you’ll need high bandwidth connections similar to cable broadband. Some internal IT departments can be hesitant to have media file traffic on the same network as regular business data. The servers that store and deliver media files need to be optimized for that purpose. You can acquire these yourself or you can contract with a company who specializes in streaming media. Most media streaming providers also have specialized networks and data centers specifically designed to handle the high bandwidth traffic of rich media.
The last piece of the streaming solution is playback. Rich media files can be encoded differently depending on your editing facilities or the target computer. Apple QuickTime, Windows Media and Adobe Flash Video are the most popular ways to encode media. QuickTime and Flash are popular Internet formats; Flash is the format used by YouTube and most other video sharing sites. Windows Media is useful on an intranet since the Windows Media Server is often installed as part of an Enterprise Windows installation.
Once your media is streaming you can place it within training applications or as links within documentation. And it can be made available outside of the work environment for personal review or even to promote or demonstrate functionality or product.
Besides desktop or laptop computers, streaming media can be viewed or listened to on all kinds of devices. A player like the Apple iPod can have files loaded on it automatically using RSS and iTunes. Its very portable and so it can go where the worker is. This would be handy in environments where having a DVD player and monitor aren’t convenient or even safe. So, the cab of an earth mover or on a shop floor or in themiddle of a pasture your rich media could be immediately available.
Rich media can be streamed to any kind of screen attached to a computer. For more generalized material that isn’t specific to a job or function large LCD panels like those found in airports for arrival and departure schedules can be placed where needed. In a play on retail’s “point of sale” I call this “Point of Work”. Screen can be scheduled to run standard rich media messages but can have specific, more timely messages “pushed” to them when necessary.
Peek at the Future
Remember what I said about DVD being useful to distribute rich media? Well, I would put your eggs in the “streaming” basket and use DVD as a secondary distribution media. Why? Because DVDs days are numbered. Two factors are causing this. First, was the development of Blue-Ray High Definition DVD. And standard definition media will be retired as international television systems convert to digital and high definition television. Even Blue-Ray has a relatively short life-span. Streaming media over the internet is predicted to overtake Blue-Ray as a distribution media is 5 years or so. So, stream first, make DVDs second.
Big Pipes
As streaming media and the technologies that enable it like compression gets better the next link in the chain are the pipes. First among those is Ethernet or CAT5 cable used in offices and to connect cable modems to home networks. These are essentially a kind of telephone wire. Coaxial cable, like that used to bring cable television signals into homes, can handle more signal like the kind needed for rich media. King of the cables is fiber optic but there hasn’t been enough of it installed to connect home to the internet and it hasn’t been practical or cost effective to install it in homes.
Wireless technology has the greatest promise to reach the most people and carry rich media signals. Include with wireless is technology like WiFi and its big brother WiMAX, but also cellular telephone. Media is streamed to telephone handsets today for advertising like movie trailers or in some cases entire movies.
Once you start streaming your rich media content wirelessly the world is literally at your fingertips. Now, your media can be exactly where your customer or employee is and can be available exactly when they want it. But there’s one more thing.
I know who you are
Besides connecting directly to your audiences’ subconscious location based distribution could be the next best thing. All computers, even those found in a cell phone, have an Internet Protocol or IP address. To use streaming media the user’s computere requests the media. With that request comes the IP address of the computer they are using. on an internal network you can determine which desks or work stations request particular files most often. Powerful for you, creepy for the user when you walk up to their desk to “help” them with a problem they’ve been having. But it gets creepier.
Using GPS, or in a pinch, the cellular network you can determine the the physical location of someone not connected to you physical network. Powerful ability when managing training or procedures for field workers. There is one other little creepy thing. Actually, very little, as in very small. Riffid. Actually that’s phonetic for RFID or radio frequency identification. RFID are tiny chips that can carry data and a small radio transmitter. They can be embedded or attached to almost anything. Walmart uses them to track inventory and purchases. With RFID you can tell who has checked out a particular tool and then, using a RFID receiver embedded in a device like an iPod, have the iPod request, through something like RSS, the rich media documentation needed for that tool or that activity. See, told you it was creepy. But cool and powerful at the same time.
So, What Do You Think?
Using rich media in your documentation or training materials may be completely new to you. It may seem complicated. It sounds like “one more thing I gotta do” right? Well, it is. Your audience (I like that term better than “users”) is expecting to be stimulated and to some extent, entertained. That’s their everyday life, not so different from yours. So, rather than do it the way you’ve always done it try incorporating some rich media and see what happens. Try it as an alternative to written procedure. If that works, replace the written material with rich media entirely.
