Modality Preferences of Different User Groups

摘要

In order to examine user group differences in modality preferences, participants of either gender and two age groups have been asked to rate their experience after interacting with a smart-home system offering unimodal and multimodal input possibilities (voice, free-hand gesture, smartphone touch screen). Effects for gender, but not for age (younger and older adults) have been found for modality preferences. Women prefer touch and voice over gesture for many scales assessed, whereas men do not show this pattern consistently. Instead, they prefer gesture over voice for hedonic quality scales. Comparable results arc obtained for technological expertise assessed individually. This interrelation of gender and expertise could not be solved and is discussed along with consequences of the results obtained.
