Look at the blackboard, everyone.

Our math teacher drew a circle on the blackboard.

Mezian is writing a sentence on the whiteboard.

And what he did was he wrote down on the board 85,000, and he said, That's her salary, and then he wrote down 12,000.

A projector connected to the computer displays the desktop image on the interactive whiteboard.

The whiteboard accepts touch input from a finger, pen or other solid object.

In many school classrooms these devices may also be used in combination with an interactive whiteboard.

I found out that advances in science rarely come upstream from an ability to stand at a blackboard and conjure images from unfolding mathematical propositions and equations.

Now, what this means is that if I run this piece of software, the camera sees the infrared dot, and I can register the location of the camera pixels to the projector pixels. And now this is like a whiteboard surface.

I was looking for a picture of graffiti, little text input language, and I found the website dedicated to teachers who want to make these, you know, the script writing things across the top of their blackboard, and they had added graffiti to it, and I'm sorry about that.

Although only a minor hit when first released, when used in the opening sequence of the movie Blackboard Jungle a year later, it set the rock and roll boom in motion.

These are the kids who now, one semester in, I can put something on the board, totally new, totally foreign, and they'll have a conversation about it for three or four minutes more than they would have at the start of the year, which is just so fun.
