Remote Testing of Usability in Medical Apps

Usability tests play an important role in any kind of software, as they limit errors and misunderstandings. Especially in the growing market of medical applications it is indispensable, but time-consuming and expensive. In or-der to improve the quality of medical applications and remove obstacles for developers, a method has been developed that simplifies testing the usability of mobile medical applications and provides additional data on compliance and effectiveness. Because this test method is remote-controlled and asynchronous, finding examiners is simplified. It also allows more subjects to be found and more data to be collected. This increases user experience and achieves more natural results as study participants act in their natural environment. In order to decide whether the app developed is suitable for this remote testing method, a questionnaire was developed to assist in the decision-making process. The described method will be tested in a study.

Mobile Application for Celiac Disease Patients' Wellness and Support

Celiac disease affects an estimated 1% of the population. The only existing treatment is a strict gluten-free diet but there are myriad aspects of managing the disease that affect the lifestyle of both the CD patient and those close to them. The goal of this study was to design, develop and test a prototype of a mobile application to promote wellness and support for individuals with CD. The proposed application's aim is to serve as a platform for CD patients and members from their social circle, to help with sharing general and specific information about four lifestyle aspects: social, emotional, food, and wellness. The application aids with the management of a gluten-free diet from the social circle perspective for the specific CD patient. Perceptions towards the usability of the application were gathered from 22 participants and analyzed via a USE questionnaire. The results from the survey reported overall satisfaction of the prototype and useful insights were gathered for subsequent versions. The general expected benefit of this evidence-based application is improved quality of life for the CD patient due to their social circle being well informed about the management of the disease and its potential complications.

Real-Time Continuous Monitoring of Cerebral Edema Based on a Flexible Conformal Coil Sensor

Objective: Cerebral edema, as a common secondary disease after stroke, can re-sult in brain hernia and even death, effectively monitoring the process of cerebral edema do benefit the prognosis of stroke patients. While current methods have their inherent drawbacks, we utilized a novel frequency shift (FS) method to re-flect the severity of cerebral edema. Method: In this paper, 12 rabbits (10 rabbits for experimental group and 2 rabbits for control group) were enrolled in the 24h monitoring experiment. Those rabbits underwent monitoring utilizing a novel flexible conformal coil sensor, for which the FS induced by changed equivalent impedance of brain was extracted as the evaluation index. Findings: The results showed that this novel coil sensor can effectively monitor the process of cerebral edema. This innovative method has great potential in clinical usage which can as-sist medical staff conducting timely treatment in terms of its early warning capa-bility.

Evaluating end-user perception towards a cardiac self-care monitoring process

This study examined the perception of end-users regarding the monitoring process offered by an innovative cardiac self-care system. The main goal is to assess the efficacy of the process implemented by a smart device designed to support people for real-time monitoring of cardio-vascular parameters in everyday life, thereby encouraging patients to be more proactive in health management. The proposed solution is a cheap mirror-based device that is easy to use, lending itself very well to domestic use as well as for telemedicine applications. We de fined six main research questions about the factors that could affect the users'acceptance of our new healthcare technology. The considered questions concern social and demographic factors, bene ts, risks and privacy, usability, acceptance and innovation. Most participants showed a positive response about the potential bene ts of the proposed self-care solution and were willing to adopt the system despite some concerns related to trust and privacy.

Walking Pace Induction Application based on the BPM and RhythmValue of Music

Walking has been attracting attention as an important means for prevention and improvement of lifestyle diseases, such as high blood pressure and diabetes. However, continuation is difficult when the walking load is high, and health benefits cannot be expected when the walking load is low. A walking pace support system is necessary in order to achieve effective walking. Hence, we are developing BeatSync, a smartphone application that realizes the induction of a natural and accurate walking pace by the rhythm of music. This application can select songs from a user's music library. However, some songs, such as songs with a fast (slow) rhythm or complex beats, are not suitable for walking pace induction. In the present paper, we consider the speed and clarity of music rhythm to be an important factor in selecting a song that is suitable for walking pace induction and make an index and clarify its effect on walking pace induction. In the present study, BPM is used as an index of rhythm speed, and RhythmValue (RV) is proposed as an index of rhythm clarity. In order to verify the effectiveness of the index, we conducted walking pace induction experiments using 30 songs with different speeds and clarities (two sets of 15 songs) with 14 participants. As a result, the experiments confirmed that the proposed index can distinguish songs that are suitable or unsuitable for walking pace induction and can select songs that are suitable for walking pace induction.

The PERFORM mask: a Psychophysiological sEnsoRs mask FOr Real-life cognitive Monitoring

Everyday life is driven by wide range of mental processes, organized in cognitive, emotional and executive functions. Although neurocognitive measures (basically, hit scores and reaction times) have been implemented for assessing these abilities, they often show poor ecological validity due to the artificial laboratory settings. Nowadays, Virtual Reality (VR) technologies are taking hold for the multisensory fruition of information. In this line, VR, that grant near-realistic scenarios, would allow the implementation of more ecological neurocognitive measures. Moreover, mental processes can be investigated via electrophysiological measures, due to the modulation of deep structures controlling the autonomic system, and in turn peripheral organs activity. According to scientific literature, measurements could derive from sensors over periocular area, that is the same area covered by a typical VR headset. The aim of this paper is to introduce the PERFORM prototype, a wearable mask with embedded sensors able to collect biomedical signals in a non-obtrusive way for the assessment of online cognitive abilities in VR scenarios. We show that PERFORM can collect data related to cardiac pulse, galvanic skin response, movements and face temperature during cognitive tasks in VR. Thanks to the specific electrode placement and the employment of VR scenario, PERFORM will be an ecological tool to assess psychophysiological correlates of online cognitive performances.

The Design of a Holistic mHealth Community Library Model and its Impact on Empowering Rural America

Healthcare delivery in rural America poses additional challenges than its urban counterpart. Rural locations more commonly face shortage of physicians, a lack of high-paying jobs with adequate insurance benefits, transportation, health literacy, a stigma with health conditions due to lack of anonymity and difficulties accessing specialty care. More than 46 million Americans, or 15% of the population, live in rural areas within the United States. Communities play an important role in the health of their residents, as social and economic factors, physical environment, and healthy behaviors make up 80% of an individual’s overall health, while clinical care accounts for only 20%. We propose a holistic mHealth community model for residents to overcome significant barriers of care in rural America by providing an application capable of integrating multiple health and safety data sources through a mobile digital personal health library application. Users are able to securely share their health data with others (e.g. primary care physician, caregiver). AI algorithms can strategically connect residents to community resources and provide customized health education aimed at increasing the health literacy, empowerment, and self-management of the user. Communities can use de-identified population health data from this model to improve decision-making and allocation of community resources.

Stop Anxiety: Tackling Anxiety in the Academic Campus through an mHealth Multidisciplinary User-Centred Approach

Anxiety-related disorders have a strong impact on our quality of life. With their epidemiological prevalence, across the population, highly exceeding the capacity for treatment in health facilities, new ways of delivering therapies are needed. The wide availability of mobile technologies, e.g., smartphones, has provided an accessible and ubiquitous platform for delivering psychological therapies and many mobile health (mHealth) systems have been proposed to support users in managing their levels of anxiety. However, many of the available tools provide features without evidence-based support of their adequateness and effectiveness. Furthermore, several tools are designed without specifically considering the users' needs and motivations, resulting in poor adherence or a lack of motivation for systematic use, hindering any positive effects. Considering the need to more closely focus on the motivations of the target users, this article describes how the efforts of a multidisciplinary team are contributing to support a user-centred approach to design and develop a tool to support anxiety management in the context of an Academic Campus. As a first materialization of this ongoing work, a proof-of-concept application is proposed (StopAnxiety), developed by adopting an iterative approach, and already providing a set of clinician-approved anxiety management techniques.

Using Data Distribution Service for IEEE 11073-10207 Medical Device Communication

The concept of an Integrated Clinical Environment can be implemented by a fully connected operation room containing devices from different manufacturers. An exchange architecture and protocol for this kind of environment is defined by the IEEE 11073 Service-oriented Device Connectivity family of standards. Therein, a Domain Information and Service Model is bound to the Medical Devices Communication Profile for Web Services, which is the specification for the information exchange technology. It is employed as the communication layer in the software library SDCLib/J that implements an Integrated Clinical Environment. In order to demonstrate that the functionality of SDCLib/J is independent of the underlying transport technology, its communication layer was replaced with an implementation of the Data Distribution Service. Therefore, its publish-subscribe pattern needed to be redesigned and transformed so that it matches the library's request-response principle.

Enabling Multimodal Emotionally-Aware Ecosystems through a W3C-aligned Generic Interaction Modality

Emotions play a key role in our life experiences. In interactive systems, the user's emotional state can be relevant to provide increased levels of adaptation to the user, but can also be paramount in scenarios where such information might enable us to help users manage and express their emotions (e.g., anxiety), with a positive impact on their daily life and on how they interact with others. However, although there is a clear potential for emotionally-aware applications, they still have a long road to travel to reach the desired potential and availability. This is mostly due to the still low translational nature of the research in affective computing, and to the lack of straightforward, off-the-shelf methods for easy integration of emotion in applications without the need for developers to master the different concepts and technologies involved. In light of these challenges, we advance our previous work and propose an extended conceptual vision for supporting emotionally-aware interactive ecosystems and a fast track to ensure the desired translational nature of the research in affective computing. This vision then leads to the proposal of an improved iteration of a generic affective modality, a key resource to the accomplishment of the proposed vision, enabling off-the-shelf support for emotionally-aware applications in multimodal interactive contexts.

A Smartbed for Non-obtrusive Physiological Monitoring during Sleep: the LAID project

The individual experience of inadequate or insufficient sleep is one of the most common health issues in the industrialized world. The 65% of Italian population reports disturbed sleep experiences, while chronic sleep disorders affect about 10% of the population. The people with inadequate and unsatisfactory sleep often suffers drowsiness during the day associated with both somatic and mental disorders. For these reasons, the systematic and continuative monitoring of sleep is one of the main objectives in preventive, personalized and participatory sleep medicine. The purpose of this paper is to describe the architecture of a "smart mattress" (SmartBed) that is the main outcome of the Italian R&D project called LAID. SmartBed will be able to non-obtrusively collect physiological and environmental parameters and signals, to processing them and to provide information about the quality of sleep, the levels of stress, and more generally the well-being of an individual. Specifically, SmartBed will be able to estimate data relating to cardiorespiratory activity, movements, body position, snoring and environmental parameters. SmartBed aims to obtain a continuative and ecological assessment of sleep and well-being of a person, in order to improve his quality of life. SmartBed will be a fundamental tool for carrying out both longitudinal and epidemiological studies on the quality of sleep and life on general population.

A Prototype System of Acute Stroke Type Discrimination and Monitoring Based on a Annulus Antenna Array: a Pilot Study

Objective: The Stroke is divided into hemorrhagic and ischemic. The two types of stroke have similar symptoms in the early stage, but treatments are completely different. Timely and effective discrimination of them can significantly improve the prognosis. Current discrimination is expensive and has the disadvantage of having to be in contact with the patient. Based on animal experiments, in this pa-per, microwave measurement technique is used to study the discrimination of two stroke types. Method: In the experiments, 10 rabbits (5 cerebral hemorrhage and 5 cerebral ischemia) are selected. Cerebral hemorrhage is induced by injecting autologous blood (1 to 4 ml) into the brain of rabbits, and the cerebral ischemia is induced by bilateral common carotid artery ligation and femoral artery blood ex-traction. The two groups are monitored by a 16-channel microwave detection system to obtain the reflection parameter caused by pathological changes in the brain. After redundancy removed from original data, suport vector machine (SVM) is used to identify the type and severity of two types of stroke. Findings: The study shows that the microwave-based stroke identification system can effectively distinguish the cerebral hemorrhage model and the cerebral ischemia model. The experimental system is very promising in pre-hospital stroke type identification be-cause of low cost, non-invasive, simple operation and rapid measurement.

Evaluating the Requirements of Digital Stress Management Systems: A Modified Delphi Study

Stress is a major health problem in this century, and it is associated with ad-verse health consequences. Its prevention and management are a great challenge, and only a minority of the affected persons receive treatment. New digital technologies offer opportunities to provide effective psychological in-terventions to address the negative consequences of occupational stress. However, the knowledge of the importance of different functions and fea-tures of digital stress management systems remains largely unexplored. This work closes that research gap by conducting a Delphi study, in which 20 ex-perts prioritized requirements in three rounds. The purpose of the present study is to enable developers of digital stress management systems (DSMS) to profitably select and use functions and characteristics of those systems, taking into account the available resources. Thus, the aim is to find DSMS that better counteract excessive stress. Finally, 82% of all requirements meet the consensus threshold.

Preliminary assessment of a smart mattress for position and breathing sensing

Sleep is a one of the most important activity for maintaining the health and well-being of each subject. In order to monitor continuously the quality of sleep of the general population in non-invasively way, we developed an innovative sensorized “smart” mattress (SmartBed). SmartBed is equipped with sensors to detect environ- mental and subject-related information. In particular, SmartBed is equipped with accel- erometers and a sensing textile matrix able to detect the distribution of pressures of a subject laying on the mattress. The purpose of this work is to demonstrate how the sensing textile matrix is not only able to detect how the subject is positioned on the mattress over time, but also it allows to detect other physiological parameters and in particular the subject's respiratory activity. In this work, we show that: (i) the sensing textile matrix allows a precise position detection; (ii) it is possible to extract accurately the respiratory frequency from the sensing textile matrix by using a specifically tailored algorithm. In conclusion, the sensors integrated in SmartBed make possible to detect important information (position and respiratory activity) to determine the quality of a subject's sleep in a robust, accurate and non-invasive way.

Preliminary Investigation on Band Tightness Estimation of Wrist-Worn Devices Using Inertial Sensors

Nowadays, wearable devices enable us to collect biological data from a massive number of people. However, the reliability of the collected data varies due to various factors such as band tightness and incorrect attachment. In this paper, we investigate the band tightness estimation by using an inertial sensor of a wrist-worn device. First, we analyze the relationship between the band tightness and the data reliability through a preliminary experiment. Then, we design the band tightness estimation as a classification problem based on frequency domain features that found effective in the preliminary experiment. The evaluation results show the effectiveness of the frequency domain features, achieving the accuracy of 81.7% for the 3-class band tightness classification.

Artificial Intelligence at the Edge in the Blockchain of Things

Traditional cloud-centric architectures for applications in the IoT are being replaced by distributed approaches. The Edge and Fog computing paradigms crystallize the concept of moving computation towards the edge of the network, closer to where the data originates. This has important benefits in terms of energy efficiency, network load reduction and improved latency. The combination of these paradigms with embedded artificial intelligence in edge devices, or Edge AI, enables further improvements. In turn, the development of the blockchain and distributed architectures for peer-to-peer communication and trade allows for higher levels of security. This can have a significant impact on data-sensitive and mission-critical applications in the IoT. We present a system architecture for the Blockchain of Things that secures data ownership and allows end-users to have tighter control over their privacy. We show how this architecture, combined with Edge AI, can be utilized in health monitoring applications in the IoT in order to protect users' privacy, manage the access to their data. Furthermore, by analyzing raw data directly at the edge layer, we inherently avoid the possibility of breaches of sensitive information, as raw data is never stored nor transferred outside of the local network.

Continuous Wellness Tracking with Firstbeat – Usability, User Experience, and Subjective Wellness Impact

Current wellness technologies are capable of monitoring wellness related parameters even 24 hours a day for multiple days. The aim of the current research was to study the usability, user experience, and wellbeing impact of the wellness analysis Firstbeat, which is based on continuous measurement of heart rate variability (HRV) and user activity. 42 persons in working life participated in an intervention study, in which their wellbeing was continuously monitored for 3-7 days and they received a detailed wellness report and a personal plan for improvement. In a follow-up questionnaire, the participants reported good usability and user experience for the system, as well as significantly reduced stress and increased self-esteem, while no significant changes were observed in the other measured aspects related to subjective wellbeing. The results suggest that the usage of continuous wellness measurement systems using electrodes in the chest area, such as Firstbeat, can be experienced positively by their users. Further research is needed on effective methods for utilizing the rich information from the measurements in achieving lasting positive changes in lifestyle.

Developing a novel citizen-scientist smartphone app for collecting behavioral and affective data from children populations

The paradigm of citizen-science, i.e., scientific research that is conducted in whole or in part by non-professional scientists, has gained popularity lately, e.g., for the purpose of crowdsourced data collection. Smartphones with their abundance and ubiquity are perfectly suited and have been widely used for crowdsourced data collection in real life settings. The ongoing, EC-funded research programme named BigO exploits the citizen-science paradigm to collect behavioral (eating, sleeping and physical activity) and affective (mood) data from children popula-tions by means of a novel smartphone application with the intention of develop-ing a decision support system to assist public health authorities in effective policy making against childhood obesity. This paper presents the development – in the context of BigO – of the myBigO app, one of the first citizen-scientist smartphone applications addressed to children for behavioral and affective data collection. This includes the design, implementation, and deployment of myBigO app in a number of data collection studies as well as its preliminary evaluation with respect to technical robustness and user experience in the context of these studies.

Intelligent Combination of Food Composition Databases and Food Product Databases for Use in Health Applications

The necessity of using food data in mobile health applications is often linked with difficulties. In Europe no standardized and quality-controlled food product databases are accessible. Data from third party sources are often incomplete and have to be checked carefully before use for errors and inconsistencies. The purpose of this approach is to improve data quality and to increase information density by developing a dedicated food data warehouse. By using the extract, transform and load processes known from data warehouse technologies, multiple data sources will be combined, inserted and evaluated. The data is cleaned up by using data profiling techniques. Data mining methods are used to merge the datasets from food composition databases and food product databases to increase information density. The aim is to analyze, if and how Big Data technologies can increase performance of data processing significantly.

Activity recognition methods generally rely on the availability of annotated training sets, where the traces collected using sensors are labelled with the real activity carried out by the user. We propose a method useful to automatically identify misbehaving users, i.e. the users that introduce inaccuracies during the labelling phase. The method is semi-supervised and detects misbehaving users as anomalies with respect to accurate ones. Experimental results show that misbehaving users can be detected with more than 99\% accuracy.

Mobile app for optimizing home care nursing

The paper presents a mobile app designed to be used by health care providers, mainly by the nurses that pay visits to the homes of the clients/ patients of the health care providers. The app should optimize the nurses activity and also the communication between the nurses and the coordinators and between the nurses and the patients. The described mobile app is part of a larger software platform as will be described in the article.
