this interactine technology is new to me. i knew that such a sort of thing must exist as they are used to ‘ask the audience’ in the show ‘who wants to be a millionaire?’. the librarians at uni gave a presentation and made it more interesting by asking us to vote on a number of questions. i would like to try using these handsets in the presentation we have to give next month, although it would involve learning how to use a new piece of equipment. it didn’t seem to be particularly difficult to use.
