Interactive white boards

This is something that I came to see for the first time when I came to UK this time. In fact the company in which I work manufactures them.
The concept is pretty simple, Anything you can do on a computer, you can do on an interactive white board. I saw the board in action, and it literally surprised me.
It consists of a white board, a projector and an electronic pen to write on the board and click on the contents on the board.
You can design games which students can play, can have interactive lessons, 3d animations of lessons, videos and all the great advantages that a computer can offer. It makes the classroom lively.
It may not be a new thing for the schools in UK, but it will be certainly a surprise for Indian schools.
It does not even confine itself to schools, it can find application in corporate world too.
A computer and a projector to project it onto white screen is not new to the corporate world in India. But to interactively do something on the content projected, the presentator has to again go back to the computer. I mean it is a one way communication from the computer to the projected image. But in case of the interactive board it s 2 way communication. You need not go back to the confined computer screen to change screens or highlight things or make notes. Remeber people using a marker and getting the projection screen dirty. Many a time people use permanant markers too to make things worse. So a circle meant for a slide remains for all the presentations to come.
Gone are those days.
Its price may be a bit high - around 63 K. But I think our universities and the private schools can definitely afford these.
And also the corporate meeting rooms.
See it to believe how good it is. Have quite a number of demos also in net.
