Slow-paced biofeedback-guided breathing training has been shown to improve cardiac functioning and psychological well-being. Current training options, however, attract only a fraction of individuals and are limited in their scalability as they require dedicated biofeedback hardware. In this work, we present Breeze, a mobile application that uses a...

Background Cough represents a cardinal symptom of acute respiratory tract infections. Generally associated with disease activity, cough holds biomarker potential and might be harnessed for prognosis and personalized treatment decisions. Here, we tested the suitability of cough as a digital biomarker for disease activity in COVID-19 and other lower...

Background: Clinical deterioration can go unnoticed in hospital wards for hours. Mobile technologies such as wearables and smartphones enable automated, continuous, noninvasive ward monitoring and allow the detection of subtle changes in vital signs. Cough can be effectively monitored through mobile technologies in the ward, as it is not only a sym...

BACKGROUND Clinical deterioration can go unnoticed in hospital wards for hours. Mobile technologies such as wearables and smartphones enable automated, continuous, non-invasive ward monitoring allowing detection of subtle changes in vital signs. In past decades, many efforts have been made to develop an automatic cough counting tool. To date, howev...

Background: Clinical deterioration can go unnoticed in hospital wards for hours. Mobile technologies such as wearables and smartphones enable automated, continuous, non-invasive ward monitoring and allow the detection of subtle changes in vital signs. Cough holds great potential for monitoring through mobile technologies on the ward as it is not o...

Effective interventions for the prevention and treatment of child and adolescent obesity play an important role in reducing the global health and economic burden of non-communicable diseases. Although multi-component interventions targeting various health behaviors are deemed promising, evidence for their effectiveness is still limited. Self-regula...

Background: Less than 2% of overweight children and adolescents in Switzerland can participate in multi-component behaviour changing interventions (BCI), due to costs and lack of time. Stress often hinders positive health outcomes in youth with obesity. Digital health interventions, with fewer on-site visits, promise health care access in remote re...

Background Slow-paced breathing training (6 breaths per minute [BPM]) improves physiological and psychological well-being by inducing relaxation characterized by increased heart rate variability (HRV). However, classic breathing training has a limited target group, and retention rates are very low. Although a gameful approach may help overcome thes...

Hintergrund: Langsames Atmen hat eine positive Wirkung auf die Herzfunktion und auf das psychische Wohlbefinden. Daher werden entsprechende Atemübungen oft bei chronischen Krankheiten empfohlen; sie werden allerdings aus verschiedenen Gründen nur von bestimmten Personengruppen ausgeübt und haben somit eine eingeschränkte Reichweite und Wirkung. Zi...

Background: Slow-paced breathing training (6 breaths/min) improves physiological and psychological well-being by inducing relaxation characterized by increased heart rate variability (HRV). However, classic breathing trainings have a limited target group, and retention rates are very low. While a gameful approach may help to overcome these challeng...

Biofeedback-based Breathing Trainings (BBTs) shows significant effect on health (WAN10, DIL16). State-of-the-art BBTs require dedicated (high cost) hardware and health professionals which represent a significant barrier to their widespread adoption. While It has been shown that a smartphone microphone has the ability to record audio signals from ex...

Non communicable diseases (NCDs) the greatest global burden. Health personnel is strongly limited to address NCDs satisfactory and thus, scalable, cost- efficient and evidence-based digital health interventions are required. This research investigates how to increase therapy adherence with a digital coach in the everyday life of patients.

Health professionals have limited resources and are not able to personally monitor and support patients in their everyday life. Against this background and due to the increasing number of self-service channels and digital health interventions, we investigate how text-based healthcare chatbots (THCB) can be designed to effectively support patients a...

The open source platform MobileCoach (mobile-coach.eu) has been used for various behavioral health interventions in the public health context. However, so far, MobileCoach is limited to text message-based interactions. That is, participants use error-prone and laborious text-input fields and have to bear the SMS costs. Moreover, MobileCoach does no...

Asthma, diabetes, hypertension, or major depression are non-communicable diseases (NCDs) and impose a major burden on global health. Stress is linked to both the causes and consequences of NCDs and it has been shown that biofeedback-based breathing trainings (BBTs) are effective in coping with stress. Here, diaphragmatic breathing, i.e. deep abdomi...
