Implications of Mobility: The Uses of Personal Communication Media in Everyday Life

This study examined the impact of mobile communications on interpersonal relationships in daily life. Based on a nationwide survey in Japan, landline phone, mobile voice phone, mobile mail (text messaging), and PC e-mail were compared to assess their usage in terms of social network and psychological factors. The results indicated that young, nonfamily-related pairs of friends, living close to each other with frequent face-to-face contact were more likely to use mobile media. Social skill levels are negatively correlated with relative preference for mobile mail in comparison with mobile voice phone. These findings suggest that mobile mail is preferable for Japanese young people who tend to avoid direct communication and that its use maintains existing bonds rather than create new ones.     

Exploring the relationship between urbanized Malaysian youth and their mobile phones: A quantitative approach

Mobile phones have become a ubiquitous consumer item. This paper aims to explore mobile phone usage, extending work beyond teenage years to examine the role of mobile phones among urbanized Malaysian youth, specifically university students. Four main categories were identified, namely, mobile phone purchasing factors and reasons to use, mobile phone usage and also behavioral issues. A mixed-mode approach involving questionnaire surveys and 24-h diaries were used to gather the relevant data. A total of 417 respondents participated in this study. The salient results indicate respondents in this study consider brand, trend and price to be the three most important purchasing factors while socializing and privacy emerged as the two most important reasons to use mobile phones. Behavioral issues related to addiction and inappropriate use of mobile phones was also observed among the respondents. Gender analysis revealed females to use their mobile phones more to socialize, gossip and as a safety device. The findings of this study could prove to be beneficial to those exploring the mobile phone adoption and usage pattern in a developing country such as Malaysia.     

Understanding emotions experienced when using a mobile phone in public: The social usability of mobile (cellular) telephones

The widespread and continued growth of mobile telephony within society means that protocols regarding acceptable public use are being continually redefined. In order to understand the different needs and motivations of mobile phone users and to assist with the development of effective policy, it is important first to consider the phone-related behaviours with which people are comfortable and those with which they become annoyed. A survey of 184 young adults was undertaken to explore the relationships between their comfort making and receiving mobile phone calls in different social contexts, their affective responses to public mobile phone use by others, and how such factors relate to key personal attributes and specific beliefs regarding calling behaviour. Mobile phone users differed in the extent to which they felt comfortable making and receiving calls in different social contexts and were less annoyed by others using mobile phones in locations where they themselves felt most comfortable making calls. Three important influences which predicted behavioural measures of phone use were found to be views regarding the application of public restrictions, desire to remain personally contactable and ‘social usability’ or anxiety regarding phone use in the presence of others. User personality and individual attributes such as age and gender were also found to be differentially associated with some aspects of phone-related behaviours.

The mobile phone use in Mainland China: Some insights from an exploratory study in Beijing

China is the primary market for the mobile phone (with almost 700 million of these devices) and one of the world’s leading countries in ICT production. Inside Mainland China, the capital Beijing and the other coastal industrialized towns have been the first to adopt and appropriate the mobile phone. Until now a certain amount of qualitative research has been devoted to the study of ICTs in China. However, quantitative studies are scarce. Here we present the results of a research based on empirical data specifically focused on mobile communication and carried out in Beijing. A structured questionnaire was personally administered to 487 respondents. This study investigates mobile phone use, its implementation in public spaces, attitudes towards its increasing complexity, opinions on its advantages and disadvantages, and its status in comparison to other technologies of information, communication and mass media in the capital of Mainland China. One main result of this study is that a very positive image of the mobile phone among our respondents was accompanied by only two disadvantages: its being a threat to privacy and its presenting the logistical problem that there is no obvious means to carry it. This latter concern should send a strong message to the fashion industry: the diffusion of the mobile phone has worsened the problem of how to wear these “little essential objects”, which up to now still continues to be unresolved.

Mobile Communication and Civic Life: Linking Patterns of Use to Civic and Political Engagement

This study employed the uses and gratifications approach to investigate how patterns of mobile phone use are linked to civic and political involvement. Findings reveal that use of the technology for information exchange and recreation are positive predictors of participation in civic life, however associations are moderated by mobile communication competence. Notably, individuals who report higher levels of comfort with mobile telephony and use it for information exchange tend to be more civically and politically engaged than those who report less comfort with the technology. These findings shed new light on the positive role of mobile communication in civil society, while highlighting competence as an emergent dimension of the so‐called “second‐level” digital divide, which has traditionally focused on computer skills.

Novel methods of faster cardiovascular diagnosis in wireless telecardiology

With the rapid development wireless technologies, mobile phones are gaining acceptance to become an effective tool for cardiovascular monitoring. However, existing technologies have limitations in terms of efficient transmission of compressed ECG over text messaging communications like SMS and MMS. In this paper, we first propose an ECG compression algorithm which allows lossless transmission of compressed ECG over bandwidth constrained wireless link. Then, we propose several algorithms for cardiovascular abnormality detection directly from the compressed ECG maintaining end to end security, patient privacy while offering the benefits of faster diagnosis. Next, we show that our mobile phone based cardiovascular monitoring solution is capable of harnessing up to 6.72 times faster diagnosis compared to existing technologies. As the decompression time on a doctor?s mobile phone could be significant, our method will be highly advantageous in patient wellness monitoring system where a doctor has to read and diagnose from compressed ECGs of several patients assigned to him. Finally, we successfully implemented the prototype system by establishing mobile phone based cardiovascular patient monitoring.     

Motivations for using the mobile phone for mass communications and entertainment

This study draws on the uses and gratifications framework to examine expanded use of a hybrid medium—the mobile phone—for mass communications and entertainment. Results of a telephone survey of 208 users show different motivations predict diverse uses of the mobile phone. Instrumental use motives drive the use of the mobile phone for news-seeking and Web-surfing. Further, the motive of pass time is significantly linked to playing video games via the mobile phone. In addition, the high-tech mobile phone enabled users to be more active: the more intensively people use mobile phones for voice calls, the more likely they will be to use mobile data services. Thus, the hybrid mobile phone bridges interpersonal and mass communication. Finally, younger users are more likely to use mobile phones for getting news and entertainment. Implications for the industry and recommendations for future research are discussed.

Towards an empowerment framework for evaluating mobile phone use and impact in developing countries

This paper challenges the dominant optimism around mobile phone contribution to socio-economic development in the developing world. It argues in favor of how mobile phones could empower socio-economically marginalized young people to overcome their marginality by examining its use within the broader socio-cultural, economic and political contexts. Drawing on the information and communication capabilities of mobile phones, this paper uses an ethnographic data and a synthesized empowerment framework to analyze the relationship between mobile phone usage and empowerment of marginalized young people in Sierra Leone. In doing so, the paper focuses on the socio-culture, political and economic uses of mobile phones. The focus on these uses is based on the argument that for mobile phones to empower marginalized young people their uses should facilitate economic, political and socio-cultural issues underpinning their marginality. The study results suggest that mobile phones empower marginalized young people to communicate and access vital livelihood information to articulate their everyday activities. However, it is not strongly evident that the use of mobile phones completely emancipates them from socio-economic and political exclusion.     

An analysis of young people’s use of and attitudes toward cell phones

Cell phones are a pervasive new communication technology, especially among college students. This paper examines college students’ cell phone usage from a behavioral and psychological perspective. Utilizing both qualitative (focus groups) and quantitative (survey) approaches, the study suggests these individuals use the devices for a variety of purposes: to help them feel safe, for financial benefits, to manage time efficiently, to keep in touch with friends and family members, et al. The degree to which the individuals are dependent on the cell phones and what they view as the negatives of their utilization are also examined. The findings suggest people have various feelings and attitudes toward cell phone usage. This study serves as a foundation on which future studies will be built.     

Near-to-Eye Display—An Accessory for Handheld Multimedia Devices: Subjective Studies

Fifty-eight people used a mobile phone/near-to-eye display combination with three different applications: movie viewing, game playing, and reading. After a 40-min immersion period participants completed several questionnaires related to the usage experience, comfort, workload, and individual features. We found many differences in user experiences between tasks as well as a number of associations between individual factors and experiences reported. Participants' opinions on the near-to-eye display/mobile phone combination were generally positive, and several benefits were reported: namely, a more engrossing experience and longer use time in the future. We also compared experiences from mobile phone/near-to-eye display setups to mobile phone and TV usage.
