Transcript

  1. ARISTOTLE There is only one condition in which we can

    imagine managers not needing subordinates, and masters not needing slaves. This condition would be that each instrument could do its own work, at the word of command or by intelligent anticipation. @bensauer
  2. • Limited shared vocabulary • Poor skills / co-ordination •

    No capacity to learn • Never sure job will get done • Turns you into the a$$h0le Using VUI is a bit like 
 dealing with Manuel…

    some ideas about what your user might say first.

 The next train from Brighton station to London Victoria station leaves in twenty minutes, at twenty past ten. It has no first class service and divides at Haywards Heath. It arrives at London Victoria at ten past eleven.
  9. “When is the next train to London Victoria?” Just right:

    
 The next train from Brighton to London Victoria leaves in 20 minutes.

    how the system should respond, and how the dialogue might continue.
