“…Binary feedback is not continuously provided but is triggered by specific events such as an alarm or event-cue related information (Ferris and Sarter, 2011 ; Galambos, 2012 ; Kaul and Rohs, 2017 ). The vibration intensity can be constant or may vary according to the event (Cobus et al, 2018 ). Continuous vibrotactile stimulation is used to convey various types of information to the users, including: (1) state feedback, encoding position and/or velocity of limbs (Ferris and Sarter, 2011 ; Krueger et al, 2017 ; Shah et al, 2018 ; Risi et al, 2019 ), (2) force feedback, encoding the amount of force exerted (Ahmaniemi, 2012 ), and (3) error feedback, encoding information regarding the goal of the task and the state of the end-effector (Wall et al, 2001 ; Cuppone et al, 2016 ; Krueger et al, 2017 ).…”

The COVID-19 pandemic has highlighted the need for advancing the development and implementation of novel means for home-based telerehabilitation in order to enable remote assessment and training for individuals with disabling conditions in need of therapy. While somatosensory input is essential for motor function, to date, most telerehabilitation therapies and technologies focus on assessing and training motor impairments, while the somatosensorial aspect is largely neglected. The integration of tactile devices into home-based rehabilitation practice has the potential to enhance the recovery of sensorimotor impairments and to promote functional gains through practice in an enriched environment with augmented tactile feedback and haptic interactions. In the current review, we outline the clinical approaches for stimulating somatosensation in home-based telerehabilitation and review the existing technologies for conveying mechanical tactile feedback (i.e., vibration, stretch, pressure, and mid-air stimulations). We focus on tactile feedback technologies that can be integrated into home-based practice due to their relatively low cost, compact size, and lightweight. The advantages and opportunities, as well as the long-term challenges and gaps with regards to implementing these technologies into home-based telerehabilitation, are discussed.

“…Results indicated statistically significant superior performance in alarm identification using the haptic arm band than with auditory alarms, but no difference in response time or learnability. Cobus et al designed an armband with three vibration motors and compared perception accuracy, learnability, distinguishability, and perceived urgency for six different vibration patterns through interviews with nurses, but did not compare performance against that of the traditional auditory signal [37].…”

Sections 5 and 6 are based on previous publications [10,11], which motivated and documented the design of vibrotactile and peripheral light alarm patterns and their general applicability in this context. The results from these earlier studies suggested the patterns we used in the final evaluation.…”

Technology plays a prominent role in intensive care units (ICU), with a variety of sensors monitoring both patients and devices. A serious problem exists, however, that can reduce the sensors’ effectiveness. When important values exceed or fall below a certain threshold or sensors lose their signal, up to 350 alarms per patient a day are issued. These frequent alarms are audible in several locations on the ICU, resulting in a massive cognitive load for ICU nurses, as they must evaluate and acknowledge each alarm. “Alarm fatigue” sets in, a desensitization and delayed response time for alarms that can have severe consequences for patients and nurses. To counteract the acoustic load on ICUs, we designed and evaluated personal multimodal alarms for a wearable alarm system (WAS). The result was a lower response time and higher ratings on suitability and feasibility, as well as a lower annoyance level, compared to acoustic alarms. We find that multimodal alarms are a promising new approach to alert ICU nurses, reduce cognitive load, and avoid alarm fatigue.
