The Role of Modality in Notification Performance

Abstract : The primary users of home care technology often have significant sensory impairments. Multimodal interaction can make home care technology more accessible and appropriate, yet most research in the field of multimodal notifications is not aimed at the home but at office or high-pressure environments. This paper presents an experiment that compared the disruptiveness and effectiveness of visual, auditory, tactile and olfactory notifications. The results showed that disruption in the primary task was the same regardless of the notification modality. It was also found that differences in notification effectiveness were due to the inherent traits of a modality, e.g.olfactory notifications were slowest to deliver. The results of this experiment allow researchers and developers to capitalize on the different properties of multimodal techniques, with significant implications for home care technology and technology targeted at users with sensory impairments.
