6 Mary Zajicek – Advanced Interfaces Group Investigations Differences between older adults and younger people: Preferred voice – young/old Importance of context Openess to route suggestions Virtual passenger Differences in people type Introvert v Extrovert

7 Mary Zajicek – Advanced Interfaces Group Example experiment Do older adults and younger people prefer a different voice type?
