ProHealth eCoach: user-centered design and development of an eCoach app to promote healthy lifestyle with personalized activity recommendations

Abstract Background Regular physical activity (PA), healthy habits, and an appropriate diet are recommended guidelines to maintain a healthy lifestyle. A healthy lifestyle can help to avoid chronic diseases and long-term illnesses. A monitoring and automatic personalized lifestyle recommendation system (i.e., automatic electronic coach or eCoach) with considering clinical and ethical guidelines, individual health status, condition, and preferences may successfully help participants to follow recommendations to maintain a healthy lifestyle. As a prerequisite for the prototype design of such a helpful eCoach system, it is essential to involve the end-users and subject-matter experts throughou…

A User-Centric Approach for Personalized Service Provisioning in Pervasive Environments

Published version of an article published in Wireless Personal Communications (2011). Also available from the publisher at http://dx.doi.org/10.1007/s11277-011-0387-3 The vision of pervasive environments is being realized more than ever with the proliferation of services and computing resources located in our surrounding environments. Identifying those services that deserve the attention of the user is becoming an increasingly-challenging task. In this paper, we present an adaptive multi-criteria decision making mechanism for recommending relevant services to the mobile user. In this context, "Relevance" is determined based on a user-centric approach that combines both the reputation of the…

A Comparative Study to Analyze the Performance of Advanced Pattern Recognition Algorithms for Multi-Class Classification

This study aims to implement the following four advanced pattern recognition algorithms, such as “optimal Bayesian classifier,” “anti-Bayesian classifier,” “decision trees (DTs),” and “dependence trees (DepTs)” on both artificial and real datasets for multi-class classification. Then, we calculated the performance of individual algorithms on both real and artificial data for comparison. In Sect. 1, a brief introduction is given about the study. In the second section, the different types of datasets used in this study are discussed. In the third section, we compared the classification accuracies of Bayesian and anti-Bayesian methods for both the artificial and real-life datasets. In the four…

Media Delivery to Remote Renderers Controlled by the Mobile Phone

In today's content delivery solutions, service delivery and control are still tightly coupled, a service typically being delivered to the same device that controls the session. We present a solution that was designed with the goal to decouple service control and delivery. Using our approach, multimedia streaming services can be delivered to off-the-shelf DLNA devices in visited networks. The service provider receives information about the remote media player and access environment via a mobile phone. Proximity technologies (e.g. barcodes, NFC) of the control device are used for the exchange of required credentials. This paper describes a typical scenario and our prototype implementation.

An Automatic Ontology-Based Approach to Support Logical Representation of Observable and Measurable Data for Healthy Lifestyle Management: Proof-of-Concept Study

Background Lifestyle diseases, because of adverse health behavior, are the foremost cause of death worldwide. An eCoach system may encourage individuals to lead a healthy lifestyle with early health risk prediction, personalized recommendation generation, and goal evaluation. Such an eCoach system needs to collect and transform distributed heterogenous health and wellness data into meaningful information to train an artificially intelligent health risk prediction model. However, it may produce a data compatibility dilemma. Our proposed eHealth ontology can increase interoperability between different heterogeneous networks, provide situation awareness, help in data integration, and discover…

Wi-Sense: a passive human activity recognition system using Wi-Fi and convolutional neural network and its integration in health information systems

AbstractA human activity recognition (HAR) system acts as the backbone of many human-centric applications, such as active assisted living and in-home monitoring for elderly and physically impaired people. Although existing Wi-Fi-based human activity recognition methods report good results, their performance is affected by the changes in the ambient environment. In this work, we present Wi-Sense—a human activity recognition system that uses a convolutional neural network (CNN) to recognize human activities based on the environment-independent fingerprints extracted from the Wi-Fi channel state information (CSI). First, Wi-Sense captures the CSI by using a standard Wi-Fi network interface car…

Delivering Services to Residential Appliances by Utilizing Remote Resource Awareness

Service providers are nowadays offering a variety of services, and in particular multimedia content delivery. Besides, consumer appliances are increasingly becoming digitalized including support for communication networks. However, it is difficult, and in many cases impossible, to use these services with standard consumer appliances, such as TV and media player devices. Rather, usage is often restricted so that they can only be accessed through web browsers from PCs, mobile phones and similar terminals. This is unfortunate, because dedicated consumer appliances are often better suited to handle the content and thereby give consumers a better experience. Within this paper, three design appro…

Using SIP Presence for Remote Service Awareness

Residential networks usually protect its devices and services behind firewalls and use private IP addresses. Therefore, appliances within a residential network cannot be discovered and utilized from external networks by standardized technologies as UPnP. In this paper, we present our concept of “Service Presence”, based on the 3GPP Presence Service that makes the service presence information remotely discoverable.

Leveraging technology for healthcare and retaining access to personal health data to enhance personal health and well-being

Abstract Health data are a sensitive category of personal data. They can result in a high risk to individuals and health information-handling rights and opportunities unless there is a sufficient defense. Reasonable security standards are needed to protect electronic health records (EHRs). All personal data handling needs adequate explanation. Maintaining access to medical data, even in the developing world, would favor health and well-being across the world. Unfortunately, there are still countries that hinder the portability of medical records. Numerous occurrences have shown that it still takes weeks for medical data to be ported from one general physician to another. Cross-border portab…

An Approach Towards Information Quality Management of Electronic Health Records

Electronic Health Records (EHR) management systems, have gained attention in many countries as public organizations working in health domain (such as hospitals and municipalities) use them to lift the quality of health care. EHRs are considered as the basis for establishing Health Information Service (HIS) systems. In spite of remarkable advantages of EHRs, the lack of quality metrics can reduce the efficiency of high level systems that are based on them. Particularly, it is smart to design a mechanism to assure the quality of data generated by sensors. In this paper, we propose an architecture in which EHRs are enriched with metadata to provide the information quality. Our architecture emp…
