“…By this metric, auditory graphs are just one example of successful, evidence-based sonic information design. Strong cases also could be made for the efficacy and success of other examples, including auditory menus (e.g., Walker et al, 2013) and sonifications for monitoring patients under anesthesia (e.g., Watson & Sanderson, 2004).…”

The search for the elusive “killer app” of sonification has been a recurring theme in sonification research. In this comment, I argue that the killer-app criterion of success stems from interdisciplinary tensions about how to evaluate sonifications. Using auditory graphs as an example, I argue that the auditory display community has produced successful examples of sonic information design that accomplish the human factors goal of improving human interactions with systems. Still, barriers to using sonifications in interfaces remain, and reducing those barriers could result in more widespread use of audio in systems.

“…Divided attention may compromise anesthesiologists' ability to monitor a pulse oximeter display (Stevenson, Schlesinger, & Wallace, 2013). Although, previous research has compared participants' ability to detect abnormal events using either sonification or visual displays whilst performing a secondary task (Sanderson et al, 2008;Seagull, Wickens, & Loeb, 2001;Watson & Sanderson, 2004), there is a paucity of research examining the effect of a secondary task on performance using sonification alone (Walker & Nees, 2011). Stevenson et al (2013) found that as cognitive load increases with additional tasks, or with increased noise levels, their ability to detect simple pitch-only SpO 2 changes diminishes by up to 17%.…”

In the operating theatre, anesthesiologists monitor an anesthetized patient's oxygen saturation (SpO 2) with a visual display but also with an auditory tone, or sonification. However, if the anesthesiologist must divide their attention across tasks, they may be less effective at recognising their patient's SpO 2. Previous research indicates that a sonification enhanced with additional sound dimensions of tremolo and brightness more effectively supports participants' identification of SpO 2 ranges than a conventional sonification does. This laboratory study explored the effect of a secondary task on participants' ability to identify SpO 2 range when using a conventional sonification (LogLinear sonification) versus an enhanced sonification (Stepped Effects sonification). Nineteen non-clinical participants who used the Stepped Effects sonification were significantly more effective at identifying SpO 2 range (100%) than participants using the LogLinear sonification (80%). Participants using the Stepped Effects sonification tended to be less disrupted by an arithmetic task (drop from 100% to 95%) than were 18 participants using the LogLinear sonification (drop from 80% to 73%). However, the disruption effect in each case was small, and the difference in disruption across sonifications was not statistically significant. Future research will test the sonifications under more intense cognitive load and ambient noise.

“…Many people have problems remembering tasks and chores in and around the home. This can be a consequence of ageing [1], the conditions for which they need care [7,23,25] or the medications they are taking [2,19]. Reminder systems can be used to set, manage, and deliver electronic reminders or notifications to someone in or around the home and might include notifications such as 'take your medication'; 'you have an appointment at 2pm' or 'remember to water the plants' [11,19].…”

“…We would argue that this is particularly important in pervasive health applications where the users are diverse and the context in which applications are used is varied and can change over time [4,11]. A multimodal reminder system could provide alternative ways to deliver reminders to the user (visual, auditory, tactile and olfactory) [24,25]. Different output modalities might be selected depending on users' capabilities and impairments, the type of reminder being delivered, user preferences, social context and the output devices available in the home for example.…”

Technology for care at home is an important factor in supporting our ageing population. These technologies need to be both accessible and acceptable to a wide variety of users if they are to be taken up and successfully used in people's homes. This paper describes the user-centered co-design and evaluation of a multimodal reminder system for the home deployed on mobile devices. Six co-design sessions (N=25 users) were carried out with groups of older users to investigate the best methods and techniques for configuring reminders and how they should be delivered within the home. Both sketches and implemented prototypes were used to gather qualitative feedback on a variety of interaction features and techniques to find what worked best for an older user group. We present the findings from the sessions in terms of the redesign of a personalisable multimodal reminder system. We also present the co-design process used and go on to discuss the value this method adds to the design and evaluation of home care technologies for older users.
