Speech in Multimodal Interaction: Exploring Modality Preferences of Hearing Impaired Older Adults
ثبت نشده
چکیده
This paper addresses usability challenges of speech and multimodal interfaces by investigating modality preferences and interaction quality of a mobile medication in-take reminder. Older users (normal hearing, hearing impairment) interacted with input and output modality conditions on a smartphone in a laboratory study. Interestingly hearing impaired users prioritized voice only interaction over other modalities, which clearly points up the relevance of speech interaction for people with hearing impairment.
