“…The responses of participants were positive, because all participants liked the multimodal form of notification (visual, vibration and sound), because it reminded them to answer the question and it was a warning sign. These results are consistent with [12], who propose that using several modalities are more effective than unimodal notifications for older people. Users commented: P1: "it got my attention", P6: "It made me doubly sure to be able to listen or feel the notification", P7: "It reminded me to answer".…”

Abstract-Elderly users are usually not the target of design of mobile applications, and they may have cognitive and physical difficulties. Mobile notifications may help them remember to use an application, promoting adoption and allowing them to become content providers. We developed a mobile application, QuestionReport, that asks users one question per day, and implemented two types of notifications: one that is activated at the same time each day, and one that is activated while using the smartphone. We tested both notification types with 18 users over a period of 8 days, measuring the time it took to answer the question after receiving the notification and their perceptions about each notification style. We found that the ideal time for users to receive a notification depends on their employment status and that users with low digital skills have less confidence in their abilities to use a mobile application such as QuestionReport.

“…Future work should consider how these notification modalities could be used to create better home care and reminder systems for older users and users with significant sensory impairments. Future work should also consider using combinations of modalities, which have been shown to be more effective than unimodal notifications for older people [5].…”

Multimodal interaction can make home care reminder systems more accessible to their users, most of whom are older and/or have sensory impairments. Existing research into the properties of different notification modalities have used younger participants rather than members of the older population at which they are aimed. This paper presents the results of a user study with older adults that examined how different notification modalities affected (a) performance in a card matching game and (b) how effective the different modalities were at delivering information. Participants were all aged over 50 and notifications were delivered using textual, pictographic, abstract visual, speech, Earcon, Auditory Icon, tactile and olfactory modalities while playing the game. The results showed that older users were influenced by the same factors as younger users, yet there were subjective differences. The implications for the design of multimodal reminder systems for home care are discussed.

“…Providing multiple ways to interact can improve accessibility, which has prompted a number of researchers to call for the inclusion of multiple modalities in home care technology [11,19,25]. In addition, researchers have argued that dynamically switching between modalities when appropriate will also lead to increased user acceptability [1,18,30,31]; for example, switching to a more private modality (e.g.…”

Multimodal interaction can be used to make home care technology more effective and appropriate, particularly for people with sensory impairments. Previous work has revealed how disruptive notifications in different modalities are to a home-based task, but has not investigated how disruptive unwanted notifications might be. An experiment was conducted which evaluated the disruptive effects of unwanted notifications when delivered in textual, pictographic, abstract visual, speech, earcon, auditory icon, tactile and olfactory modalities. It was found that for all the modalities tested, both wanted and unwanted notifications produced similar reductions in error rate and task success, independent of modality. The results demonstrate the need to control and limit the number of unwanted notifications delivered in the home and contribute to a large body of work advocating the inclusion of multiple interaction modalities.
