Mobile multimodal interaction for older and younger users

Abstract

Since they can integrate a wide range of interactive modalities, multimodal interfaces are considered to improve accessibility for a variety of users, including older adults. However, only few works have actually explored how older adults approach multimodal interaction outside specific contexts and have done so mainly in comparison to much younger users. This study explores how older (65+ years old), middle-aged (55-65 years old) and younger adults (25-35 years old) use mobile multimodal interaction in an everyday activity (i.e. taking photos with a tablet) by using midair gestures and voice commands, and investigates the differences and similarities between the considered age groups. Preliminary findings from a video-analysis show that all groups easily combine the proposed modalities when interacting with a tablet device. Furthermore, compared to younger adults, older and middle-aged adults show similarities in the way they perform gesture and voice commands.
