The first version of I-systems, called I-waiter 1.0, is capable of dispensing water bottles when desired. This version can be used in concert, formal gathering, official meeting and all other organized places. Another version for this is the I-secretary. This system is capable of working in an office providing office stationary, reading predefined memos, etc. Yet more interesting version for I-system comes from the idea of the guides, who accompany tourists, giving out information about the place and event. So does this version of I-guide. This version has an inbuilt module which enables it to speak out information and important facts about the place like in museums or science parks.
