Remote Control System

This paper presents a computer remote control system using speech recognition technologies of mobile devices and wireless communication technologies for the blind and physically disabled population as assistive technology. These people experience difficulty and inconvenience using computers through a keyboard and/or mouse. The purpose of this system is to provide a way that the blind and physically disabled population can easily control many functions of a computer via speech. The configuration of the system consists of a mobile device such as a smartphone, a PC server, and a Google server that are connected to each other. Users can command a mobile device to do something via speech; such as writing emails, checking the weather forecast, or managing a schedule. These commands are then immediately executed. The proposed system also provides blind people with a function via TTS(Text To Speech) of the Google server if they want to receive contents of a document stored in a computer.

M-commerce applications have evolved out of e-commerce applications, riding on the rapid advancement in mobile communication technologies in the past decade. The diffusion of applications on the Internet into the mobile computing environment has taken an accelerating pace ever since. Virtually all e-commerce and m-commerce applications rely on the provision of information retrieval and processing capability. In this regard, database systems serve as the information source and repository for these applications, backed by efficient indexing mechanism. Bean (2003) gave a good report on supporting Web-based e-commerce with XML, which could be easily extended to m-commerce. An m-commerce framework, based on JINI/XML and a workflow engine, was also defined by Shih and Shim (2002). Customers can receive m-commerce services through the use of mobile devices, such as pocket PCs, PDAs, or even smart phones. These mobile devices together with their users are often modeled as mobile clients. Central to supporting m-commerce applications are three types of entities: mobile device, mobile communication, and database. In particular, we are more interested in providing efficient access mechanisms to mobile-client-enabled database servers, which are often called mobile databases. Mobile databases contain the core information to support the underlying m-commerce applications, while the use of mobile devices serves for the hardware platform, with mobile communication providing the necessary connection between mobile databases and mobile devices for interfacing with real users or customers.

Everyday Resistance

Over the past decades, waves of political contention involving the use of information and communication technologies have swept across the globe. The phenomenon stimulates the scholarship on digital communication technologies and contentious collective action to thrive as an exciting, relevant, but highly fragmentary and contested field with disciplinary boundaries. To advance the interdisciplinary understanding, Shifting Dynamics of Contention in the Digital Age outlines a communication-centered framework that articulates the intricate relationship between technology, communication, and contention. It further prods us to engage more critically with existing theories from communication, sociology, and political science on digital technologies and political movements. Given the theoretical endeavor, Shifting Dynamics of Contention in the Digital Age systematically explores, for the first time, the influence of mobile technology on political contention in China, the country with the world’s largest number of mobile and Internet users. Using first-hand in-depth interview and fieldwork data, it tracks the strategic choice of mobile phones as repertoires of contention, illustrates the effective mobilization of mobile communication on the basis of its strong and reciprocal social ties, and identifies the communicative practice of forwarding officially alleged “rumors” as a form of everyday resistance. Through this ground-breaking study, Shifting Dynamics of Contention in the Digital Age presents a nuanced portrayal of an emerging dynamics of contention—both its strengths and limitations—through the embedding of mobile communication into Chinese society and politics.

<p class="ArticleTitle">In recent years, the increasingly innovative and diverse mobile devices have significantly promoted the mobile device-based shopping. What factors influence this kind of shopping? Will consumers purchase things with mobile devices? These are two topics that need to be explored. Through the literature analysis and the empirical research, this study aims to analyze the quality of information, system, service and mobile devices on the mobile device-based shopping platform. Moreover, it studies the attitude of consumers towards mobile device-based shopping, their willingness to adopt the shopping method and the behavioral relationship model in the actual mobile device-based shopping as well as compares the groups of different frequencies of the Internet use in terms of the relationship model.</p>　　With the convenient sampling, this study made an investigation among some of those who had experienced shopping on such mobile devices as tablets or smart phones. The 765 retrieved valid copies of questionnaire were divided into three groups—“often”, “average” and “seldom” according to the frequency consumers undertook mobile device-based shopping and were then compared. The results showed that there were significant differences among the three groups in four relationship paths, including: 1) the information quality of the mobile device-based shopping platform has more significant positive influence on consumers’ attitude path of mobile device-based shopping in the “average” group than in the other two; 2) the service quality of the mobile device-based shopping platform has more significant positive influence on consumers’ attitude path of mobile device-based shopping in the “seldom” group than in the other two; 3) the preference for mobile device-based shopping has much significant positive influence on the behavior path of mobile device-based shopping in the “often” group. According to the research results, different groups have different behavior models. These results can serve as reference information in the decision-making of those who establish mobile device-based shopping platforms and manufacture mobile devices.

Increases in mobile phone ownership and Internet access throughout Africa continue to motivate initiatives to use information and communication technologies (ICTs)—in particular, mobile phones—to address long-standing socioeconomic problems in the “developing world.” While it is generally recognized that mobile phones may help to address these problems by providing pertinent information, less widely known is exactly how (and if) a handset’s human–computer interface—that is, its software and hardware design—supports this form of communication. The concept of “affordances” has long been used to answer such questions. In this paper, we use Hartson’s definition of affordances to qualitatively investigate rural Kenyan women’s interactions with their mobile phones. Our detailed analysis provides empirically grounded answers to questions about the cognitive, physical, and sensory affordances of handsets used in our field sites and how they support and/or constrain mobile communication. We then discuss the implications of our findings: in particular, how this affordance-based approach draws attention to mobile phones’ design features and to the context in which they and their users are embedded—a focus which suggests new design and research opportunities in mobile communication.
