Nowadays, technology has made it relatively easy to build a smart home environment. To better interact with the devices and services available in such a smart environment, the user interface plays an important role. In view of this, this paper presents a vision and projection-based user interface that allows the user to remotely control the devices through the movement of fingertips over a projected surface, thereby offering a more natural and intuitive way of user interaction. To realize the proposed bare hand interface, a real-time fingertips detection method and a fingertips tracking method are proposed, where the fingertips detection is accomplished by applying computer vision techniques to the images acquired by a camera. In addition, we propose a gesture recognition model to enable a mapping from the position of fingertips to the high level user actions and events, so that several common gestures (e.g. tap/click and drag) can be correctly detected. To demonstrate the feasibility of the proposed approach, a proof-of-concept experiment, a prototype of the projection-based user interface, is conducted and presented based on a typical smart home scenario.

The next generation of health promotion services should consider to retrieve the context data from the wireless sensor network that around user's current environment. The aim of this study was to apply the environmental sensorial data as input and to predict user requirement in the context through analyze the collected data. To do so, the study followed the approach of user-centered design and applied the activity theory as a theoretical framework to introduce an activity-based open platform for recognizing and supporting the relatied activities of health promotion. Specifically, the study introduced a data processing method for analyzing the context-awareness data by using an activity-based ontology technology. The detail of the proposed model includes the activity ontology, data processing, activity model, and use scenarios will be introduced.

Traditionally, teamwork faces problems related with communication and coordination in both local and distributed environments; software development is not an exception. Some of the most significant problems in communication are the lack of reciprocity and fast response, especially in distributed environments. Communication should be motivated and maintained through the project development. Early media such as e-mail and forums do not possess such source of motivation and synchronization. New media such as Facebook and G+ have such elements that motivate team members, especially young developers, to remain online facilitating the communication just in time. In this paper we present some experiences using the most popular social media such as Facebook, G+, Skype, and Dropbox in developing software projects. Our study presents statistics of what kinds of communication and coordination issues are properly implemented using Facebook. Based on this, we present an initial set of metrics to assess how communication, coordination and knowledge sharing are implemented in these kinds of distributed environments.

Efficient resource provisioning and allocation enable the reduction of energy consumption in cloud providers and make providers to get more profits. When the client submits more and more jobs to a cloud provider, the available resources in a cloud provider may not be enough for completing these jobs. Therefore, the cloud providers have to lease more available resources from others. In order to solve this problem, this study proposes a combinatorial auction-based approach for dynamic resource provisioning and allocation, considering the client requests with deadline. Experimental results show that our proposed auction-based approach could get more profit.

With upcoming regulation, the task of implementing transparency services gets a critical part of all electronic commerce. Within inter-organizational business processes, this task becomes more challenging, as even determination of the topology of a service composition within such a setting is getting a complex issue of its own. In this paper, we shed a light on the functional, legal, and economic issues and challenges of realizing useful transparency services. We also propose a decentralized solution for supporting anonymized collection of transparency-relevant information based on the principles of service-orientation.

Due to the prevalence of sensors such as security cameras or environmental monitoring, sensor data stream delivery which means delivering the observed data continuously attracts great attention. For sensor data stream delivery, receivers collect data in various cycle by the use of them. We proposed a P2P-based method to distribute communication loads in the case of delivering the sensor data stream that have different data collection cycles. Although the existing method distributes communication loads by re-delivering the sensor data that have the same collection time, the load concentration to the longer cycle receivers is probable. Therefore, we propose a P2P delivery method to distribute communication loads by the estimation of each receiver's loads and re-delivering from the lowest load receiver. We evaluated the effectiveness of proposal in simulation. By the result of simulations, we confirmed the load distribution in the case of many receivers at same time.

The importance of information ethics has emerged with the advent of the information and knowledge society. Especially, information ethics education and research about gifted students in computer science (CS gifted students), who play key influencers in IT development, is becoming more important. But the amount of systematic research on CS gifted students' information ethics is insufficient. This study measured the information ethics level of CS gifted students and also analyzed various factors that influence information ethics. For this study, 30 CS gifted students were selected and their levels of information ethics, moral judgment and problem solving abilities with regards to computer science (CS problem solving) were measured, then their abilities to control their emotions were measured through a cognitive psychological method. The results of the analysis showed that there were no significant demographic component differences (gender and grade level), but moral judgment level and emotional control were the highest correlating variables for information ethics, with moral judgment being the most influential factor.

The main subject of this paper is how to construct virtualization in the cloud for implementing video and medical image services. The framework of cloud service contains the infrastructure, OS, virtual machines, platform, cloud web application services, and cloud devices. We build medical image and video services on cloud IaaS environment, which integrates KVM and OpenNebula open sources to provide a cloud virtual environment for end users. Also, Hadoop open source, as cloud PaaS, is used for these two cloud services. This paper realizes medical image and video services that are easy for users to understand, access, and operate with them in the cloud. The proposed system can improve medical imaging storage, transmission stability, and reliability while providing an easy-to-operate management interface.

Despite the rapid progress of Information-Centric Network (ICN) research in the last few years, its key component route-by-name faces feasibility and efficiency challenges since we have to deal with a large number of information objects. In this article, we take a practical approach to the challenge of feasible and efficient name resolution service. Because of the similarity between the naming scheme in ICN and URI, we evaluate the time and space complexity of a typical data structure for lookup of ICN names using URIs collected from the traffic trace of a campus backbone. We propose a simple and empirical Distributed Resolution Service (DRS) scheme according to the time and space complexity model. The proposed scheme can handle at least 1012 name entries using about 3, 300 nodes with commodity hardware. Finally, we optimize the proposed distributed resolution service scheme with regard to network performance.
