Pervasive computing at tableside : a wireless web-based ordering system

Purpose &ndash; The purpose of this paper is to introduce a wireless web-based ordering system called iMenu in the restaurant industry. Design/methodology/approach &ndash; By using wireless devices such as personal digital assistants and WebPads, this system realizes the paradigm of pervasive computing at tableside. Detailed system requirements, design, implementation and evaluation of iMenu are presented.Findings &ndash; The evaluation of iMenu shows it explicitly increases productivity of restaurant staff. It also has other desirable features such as integration, interoperation and scalability. Compared to traditional restaurant ordering process, by using this system customers get faster and better services, restaurant staff cooperate more efficiently with less working mistakes, and enterprise owners thus receive more business profits. Originality/value &ndash; While many researchers have explored using wireless web-based information systems in different industries, this paper presents a system that employs wireless multi-tiered web-based architecture to build pervasive computing systems. Instead of discussing theoretical issues on pervasive computing, we focus on practical issues of developing a real system, such as choosing of web-based architecture, design of input methods in small screens, and response time in wireless web-based systems.<br /

Ubiquitous Computing Based Mobile Commerce : Toward the Ubiquitous Commerce

Mobile commerce is heading for advanced fourth generation (4G) mobile systems. However, rapid development of ubiquitous computing technology can implement and complement the 4G mobile systems. It enables anticipation that ubiquitous computing technology creates the new commerce, so called ubiquitous commerce. This paper analyzes the characteristics of mobile commerce service and ubiquitous computing service, and then extracts the core requirements for ubiquitous commerce. Moreover, this paper suggests technical requirements for the ubiquitous commerce. These requirements can lead the development of technology for the future and suggest the milestone that mobile commerce in present heads for

Three Phases RFID Adoption: A Road Map to Success

Radio frequency identification (RFID) uses radio frequency technology for automated identification. The use of RFID brings the second source of information to enterprise management. It is said the second source is because, in the conventional approach, the information is shared among the various units through an integrated enterprise system. In this study, we define three layers of networks, i.e. Intranet, Extranet, and Internet, can be used to share RFID data and the adoption of RFID technology can be recognized into three phases: standalone adoption, supply chain adoption, and global adoption. Issues in each adoption will be address as well as road map to the success will be included

Enabling ubiquitous data mining in intensive care: Features selection and data pre-processing

Ubiquitous Data Mining and Intelligent Decision Support Systems are gaining interest by both computer science researchers and intensive care doctors. Previous work contributed with Data Mining models to predict organ failure and outcome of patients in order to support and guide the clinical decision based on the notion of critical events and the data collected from monitors in real-time. This paper addresses the study of the impact of the Modified Early Warning Score, a simple physiological score that may allow improvements in the quality and safety of management provided to surgical ward patients, in the prediction sensibility. The feature selection and data pre-processing are also detailed. Results show that for some variables associated to this score the impact is minimal.Fundação para a Ciência e a Tecnologia (FCT

A Policy Architecture for Enhancing and Controlling Features

Abstract. Features provide extensions to a basic service, but in new systems users require much greater flexibility oriented towards their needs. Traditional features do not easily allow for this.We propose policies as the features of the future. Policies can be defined by the end-user, and allow for the use of rich context information when controlling calls. This paper introduces an architecture for policy definition and call control by policies. We discuss the operation of systems based on such an architecture. An important aspect of the architecture is integral feature interaction handling

M-Commerce Services: Promises and Challenges

This paper provides a brief description of two distinct approaches for designing and implementing M-Commerce services, the dominant location-based approach, and the gradually emerging context-based approach. The authors argue that the context-based approach, while more complex, holds greater potential for the future, given its inherent capability to reflect/support natural human social structures and behaviors

A Business Intelligence Perspective on the Future Internet

Business Intelligence aims at providing decision support based on available information and tailored to the recipient‟s context due to the level of aggregation and form of delivery. The future internet will dramatically broaden both the spectrum of available information and the user‟s possible contexts. Further, we do not only expect a quantitative dart but a qualitative switch which will require the application of new methods and paradigms. This paper‟s aim is to systematically analyse implications of the future internet on Business Intelligence in order to identify possible perspectives, chances and risks for BI and vice versa by summarizing and categorizing current research

The Future of Software Engineering by 2050

According to the huge criticality of using advanced software systems and the great demands of providing updated and qualified programs, this paper reflects some future perspectives towards the importance of software in managing everything in the world life over the next thirty years. Moreover, the paper presents the challenges which face the recent and the future generations as a result of this huge revolution of technology and automations. In addition to that, the writer would provide some solutions for those obstacles in order to enhance the role of software engineers in 2050. Also the paper reviews the related literature and surveys the point of view of software engineering experts by assigning an online interview with six open ended questions to examine their perspectives towards the future of Internet of things, Artificial intelligence, ubiquitous computing, and system of systems. The majority of ideas reflected the humanity fears of technology and replacing people with robots in the job fields. Furthermore, some experts encouraged the idea of having smart homes, and wearable devices Keywords: advanced Software; system of systems; 3D building printer, internet of things, artificial intelligence, ubiquitous computing, and system of systems.

Values of Silent Commerce: A Study Using Value-Focused Thinking Approach

Silent commerce is a special type of u-commerce that uses RFID and sensor technologies to make objects intelligent and interactive. The unique features available in silent commerce will provide benefits and added values to users. This study aims to uncover the values of silent commerce from the customers’ perspectives and understand what customers desire and expect from silent commerce. The scenario-based method was adopted to provide subjects with the necessary background information and knowledge about the emerging silent commerce phenomenon. The Value-Focused Thinking approach, which provides a systematic way to articulate and organize values, was used to identify the values of silent commerce to users. The result of this study is a means-ends objective network that depicts the fundamental objectives of using silent commerce and how the fundamental objectives can be achieved through means objectives. The findings can serve as a conceptual foundation for future research in the u-commerce area and provide useful guidelines to practitioners in developing and implementing silent commerce applications
