Integration of multimodal alarms into Google Glass

Computational approaches to alleviate alarm fatigue in intensive care medicine: A systematic literature review

“…Most of these papers are from Cobus et al since their proposed method includes hardware. These user studies consisted of the testing of the prototype ( 47 , 73 , 76 , 77 ), performance of tasks ( 46 , 47 , 77 ), interviews ( 45 , 58 ), as well as pilot sessions ( 42 ). Not all the papers included the number or the background of the participants in their user study.…”

“…This subgroup consists of ( 39 , 44 – 47 , 76 , 77 ). The first publication presents a dynamic system for alarm loudness regulation with respect to ambient noise ( 39 ).…”

“…The modalities used are vibration, peripheral light and (bone conduction) sound. They present a vibrotactile wearable alarm system worn on the upper arm ( 47 ) as well as different versions of a head-mounted display for alarm presentation showing an evolution throughout the years 2017 to 2019 ( 45 , 46 , 76 , 77 ). The head-mounted display delivers alarms as well as alarm-relevant information, such as the patient’s vital data, the sensor, the respective patient’s name or its priority.…”

Examining the efficacy of vibrotactile displays for monitoring patient vital signs: Six laboratory studies of change detection and state identification.

“…Whether such placement would affect metaphorical mapping (i.e., because the linear relationship between tactors would be disrupted) would need to be tested. There are other possible redesigns, such as altering the intensity or patterning of vibrotactile pulses, which have been used by other researchers in different contexts (Cobus & Heuten, 2019; Cobus et al, 2019; Gomes et al, 2018). Further researchers have also tested other sites for tactors (Alirezaee et al, 2017; Barralon, Dumont, et al, 2009; Barralon et al, 2008; Ferris & Sarter, 2011; Gay-Betton et al, 2017; Ng et al, 2008, 2005), but as noted earlier there are practical difficulties associated with donning such systems.…”

“…Finally, Cobus and colleagues have examined how alarm information can be effectively distributed across clinicians and locations within an intensive care unit, again exploring wearable alarm solutions including the use of multimodality. After initially gathering requirements with clinicians in the field Cobus and Heuten (2019) and Cobus et al (2018, 2019) tested eight different ways of conveying three urgency levels, unrelated to any particular vital signs. They found that patterns that increased the repetition rate or tacton duration were interpreted as more urgent.…”
