I was watching a TV program which was showing that sophisticated gadgets like coffee machine, car navigation units and ticket dispensers at Rail stations have become so complicated that almost everybody struggles to use them properly. The fully automatic coffee machine had a function called milk island, which the user could not find from the manual. The touch screen ticket dispensers had complicated code input systems and one user mentioned why don't you make it like the dispensers in Singapore. Every station has a button. You press it, insert money and voila! Your ticket is printed. But in Germany you have to go through many complicated menus.
The navigator had a voice recognition system which was not responding to certain words.
The bottom line is that these technologies have been incorporated without keeping in mind that most of the users are not geeks and are not comfortable with complicated menus.
The machine does not isolate man from the great problems of nature but plunges him more deeply into them. - Antoine de Saint-Exupery
