Machines are believed to be more than they are. We are now talking about interaction between human and computer, but are there some simularities in perception processes of both sides? The main instance, wich makes this interaction available, is human body with senses it have. Now computer can easily imitate some of the senses and actually use them to express ‘itself’ (never getting close enough). Seems to be an inspiring statement until we realise that those efforts are not more than analysing input and expressing the same information in different way.
Each of three tetrahedrones stand for one of the senses (in imitation of two of them computer succeded quite well, while the third one can not been reached).
