Enhancing the smartroom system with e-tourism services

The SmartRoom system is a service-oriented application for assisting such collaboration activity as conference or meeting in a room equipped with computing and presentational devices and Internet access. The development is open source and based on the Smart-M3 platform. In this paper, we consider advanced scenarios for SmartRoom to enhance the latter with e- Tourism services. We introduce a smart space based architecture for this enhancement. We provide an ontology for representing and sharing the tourism-related information for service construction. Based on the architecture and ontology, several case study services are designed. In particular, we implement a service for collaborative construction of a social program for conference participants. The implemented service is integrated into the SmartRoom system and demonstrates the feasibility of the proposed design

Design of semantic information broker for localized computing environments in the internet of things

Emerging communication technologies of the Internet of Things (IoT) make all the devices of a spatial-limited physical computing environment locally interconnected as well as connected to the Internet. Software agents running on devices make the latter “smart objects” that are visible in our daily lives as real participating entities. Based on the M3 architecture for smart spaces, we consider the problem of creating a smart space deploying a Semantic Information Broker (SIB) in a localized IoT-environment. SIB supports agent interaction in the smart space via sharing and self-generating information and its semantics. This paper proposes a renewed SIB design with increased extensibility, dependability, and portability. The research done is a step towards an efficient open interoperability platform for the smart space application development

Proactive Personalized Mobile Multi-Blogging Service on Smart-M3

This paper discusses the project targeted in development of proactive, personalized and composite services for the blogosphere. By applying the smart spaces paradigm we have developed an approach for composition of blog spaces. We contribute formal technique for construction of proactive and personalized service for bloggers as well as for its integration with external applications. The proposed technique is implemented in SmartScribo application on top of the Smart-M3 platform. The developed prototype solution has confirmed that the approach results in services with the next quality level

Study of active subscription control parameters in large-scale smart spaces

The development of smart spaces for Internet of Things (IoT) environments meets the scalability challenge since many participants are involved into the distributed computation. In particular, many sensors continuously provide data, many reasoners analyze the sensed data to construct services, and many mobile clients regularly join and leave the smart space to consume the services. The network interaction is information- driven, using a semantic information broker, which implements a passive strategy for subscription. The strategy leads to performance bottleneck. We continue our study of the active control strategy, when a part of subscription processing is delegated to the subscribers. The client multiplicatively decreases its check interval, if subscription notifications are lost, and additively increases the interval, otherwise. We study the role of strategy parameters: the client can select their values preliminary and keep fixed, or the client can change them dynamically depending on the recent situation. With the aim we provide mathematical model which represents important performance metrics as a function of strategy parameters. Analytical result are validated by experimental evaluation. Additionally, our simulation experiments evaluate the scalability in dependence on the number of participants

Smartphone-Oriented Development of Video Data Based Services

The massive introduction of video capturing devices in Internet of Things (IoT) environments leads to development of various video data based services. In this paper, we consider the need and background on the video data based services in IoT environments. Based on the smart spaces approach, we introduce the architecture and distributed configurations to construct such services using primarily local devices and to deliver such services using smartphones. We discuss possible data models that can be used on such mediatory components as a local video server and a semantic information broker

Smart museum of everyday life history in Petrozavodsk State University: Software design and implementation of the semantic layer

Since 2016 a smart museum of everyday life history has been developed within the History Museum of Petrozavodsk State University. This R&D project aims at solutions to the two important problems for creating a digital service-oriented environment for museum visitors and personnel: 1) offering personal recommendations on the museum collection with the use of semantic ranking methods and in context of the user and exhibition, 2) collaborative addition of information sources and their semantic annotation within the museum collection. Such solutions form the semantic layer of smart museum environment. This paper introduces our a) system design models for agent- based programming of museum information services, b) ranking models for semantic data mining in historical and cultural heritage domain. Our software implementation demonstrates the feasibility of the proposed models in respect to the user mobility, service personalization, and collaborative work opportunity

Towards a personal at-home lab for motion video tracking in patients with Parkinson's disease

Many digital healthcare services now employ the opportunities of mobile and smart Internet technologies. The Internet is used to deliver such services as medical consultations, diagnosis, and prescriptions. The services are constructed and delivered in the ubiquitous style - anywhere, anytime, and using surrounding devices of our everyday life. In this paper, we discuss the opportunities of motion video tracking in at-home settings for a patient. Parkinson's disease (PD) serves as a case study. First, we define the problem of motion video tracking in PD patients. Then, we consider Internet-enabled methods for motion video tracking, which are essentially restricted with professional settings of a medical environment. Finally, we propose to create a personal at-home lab based on such cheap home-based cameras as any smartphone has. Our early experiment shows that such cameras provide reliable capture quality for the practical use in PD patient motion video tracking

Smartphone-Based Microphone: A Multi-User Service for Collaborative Work

SmartRoom is a smart space-based system for assisting such collaboration activity as a conference or a meeting. The assistance is in the form of digital services provided to the users, having personal mobile devices (e.g., smartphone), in a multimedia-equipped room. In this work, we continue our development of microphone service, which allows a SmartRoom user to exploit her/his smartphone as a microphone wirelessly linked with an audio system in the room. The service supports new scenarios for voice communication between a current speaker and other participants. In the considered case study, the client part is implemented for Android mobile devices

Smartphone-based Motion Video Tracking in Patients with Parkinson’s Disease

Mobile treatment is an important component in regular medical support for people in their everyday life. A mobile application on a smartphone can recognize human images. thus tracking the behavior and gait. In this demo, we show simple use of a smartphone and its camera for motion video tracking of patients with Parkinson’s Disease. Our results indicate that such low-cost cameras can provide reliable capture quality in at-home settings

Control strategies of subscription notification delivery in smart spaces

The paper studies performance of the subscription operation in smart spaces for the case when the notification delivery to a client is subject to losses. We consider an active control of the check interval for the client to adapt to the observable loss rate. The adaptive strategy takes into account the number of lost notifications. The performance is analyzed and compared with other strategies under simplified assumptions about the loss distribution
