  24. Characteristics of IVR • Inpatient user • Urgent; want to talk to real person • Lack of user control • It’s both bad and good • Typically narrow but deep phone tree, resulting long sentences

  25. Visual vs. auditory menu Visual Linear Menu 27

  26. Visual vs. auditory menu IVR System Visual Linear Menu 28

  27. Problems of IVR system • Speech is serial and slow (Slowiaczek and Nusbaum 1985)

  28. System Visual Outputs time Mouse Input User Problems of IVR system • Synchronous vs. asynchronous communication Synchronous

  29. System System Visual Outputs Audio Audio time time Press Key Press Key Waiting Waiting Mouse Input User User Problems of IVR system • Synchronous vs. asynchronous communication Asynchronous Synchronous
