Sonstiges » interactive whiteboard?

Hello,
I am new in this field and i want to know about this field. I read some magazines,books.I want to stand in this field.An interactive whiteboard is an instructional tool that allows computer images to be displayed onto a board using a digital projector. The instructor can then manipulate the elements on the board by using his finger as a mouse, directly on the screen. Items can be dragged, clicked and copied and the lecturer can hand write notes, which can be transformed into text and saved. is it correct?I went through many resources and also checked Business Whiteboard but did not find the right solution. Please help me out.

Any help will be appreciated.
Thank you.
