A big "thank you" to my readers for responding to my online poll "What is the SMART Board?"
I would like to share with you why I think this is such an important question and why I think the SMART Board is such an innovative and exciting tool to use in the classroom.
The possible answers and the percentage of people who answered the question What is a SMART Board? are:
- An output device (1%)
- An input device (10%)
- Both an output and input device (82%)
- Neither (2%)
- I'm not really sure (5%)

The technical answer to the question is "An input device." While the answer may surprise many of you, it's not surprising that over 80% of you thought it was "Both an output and input device."
First a reminder, an input device is anything that gives data or information to the computer. The most popular forms of input devices are the mouse and the keyboard. Is the SMART Board an input device? This is a no-brainer. When you touch the SMART Board, it sends data to the computer so it is indeed an input device. An output device, on the other hand, is anything that gives data or information to the user. Common output devices are printers and monitors.
Is the SMART Board an output device?
I will admit that the answer to this can be a little tricky. It is this "trickiness" that makes the SMART Board such a wonderful and fun tool to use. Firstly, I would like to ask you if your mouse is an output device. Does the computer send any signals to the mouse that could tell you anything about what's happening on the computer? For example, does the computer make your mouse vibrate or light up or do anything at any time? The simple answer is no. The mouse does not give you any information about what the computer is doing. So how do you know what your mouse is doing? The answer is that the computer sends information to the monitor and the monitor shows you a picture of a cursor. You rely on the cursor to tell you when to click your mouse.
Now for the SMART Board. Does the computer send any information to the SMART Board to let you know what it's doing? The answer is no; the computer sends information out through the projector. The projector's image on the SMART Board is the data that tells you what's happening on your computer. Therefore, the SMART Board is not an output device.
The transparency in which the SMART Board works in conjunction with the projector (output device) is what makes the SMART Board such a fun and exciting tool to use. It is this transparency that makes it seem like the SMART Board is both an input and output device.
Two things help make it seem like the SMART Board is both an input and output device. Firstly, because the projector is projecting an image on the surface of the SMART Board, you never look at the actual output device (the projector) to see your data, you look at the SMART Board. Secondly, the SMART Board eliminates the need to control a separate object (your cursor) to control your computer. This is a requirement when using the mouse. With the mouse, you're relying on the monitor to show you where the cursor is to tell you when to click the mouse. With the SMART Board, YOU become the cursor.
I believe this subtle difference gives us the perception that we're interacting directly with the information. It's the difference between telling a taxi driver where to take you and driving there yourself. (I don't know about you, but I remember being a lot more excited the first time I drove a car compared to the first time I took a taxi ride.)
All of this is perception of course. However, I believe it is this perception which helps engage people when they're using the SMART Board. This is exactly why I believe the iPhone is such a popular and fun tool to use. With the iPhone, we don't use buttons to make a cursor move up or down and select the things we want, we simply touch on what we want. I believe this type of interaction is much more powerful than we know and I believe this is what puts the SMART Board in a class by itself.
Let me know what you think!
