Fuji Denki Co has developed computer-assisted instruction materials to teach people to use fuzzy logic on a personal computer: developed in collaboration with the NTT Central Electronic Communication Academy and Professor Kaoru Hirota of Hosei University, the software is claimed to be simple enough that unskilled users and university students can learn to apply fuzzy logic – where the computer is asked to look for a best match where none are exact, for instance recognising that comapny almost certainly means company; the package comes with a manual and floppy disk for either NEC Corp’s PC9800 series or Fujitsu’s FM series; the system costs $450.
