With the vagaries of nature being unpredictable, it’s now more important to have access to weather forecast for short periods of time. Many businesses, including those in agriculture and the fishing industry, depend on an hourly update of the weather. The access to such weather nowcasting data has, until now, been through traditional media like the television, radio, et cetera, while new media of communication such as mobile devices, have been largely unexplored. The advancement in MEMS (Micro Electrical Mechanical System) technology has now brought forth various sensors that are miniaturized and can be integrated or embedded into various other systems used presently. Environmental sensors that measure weather parameters are miniaturized to fit the size of a mobile. The system aims to integrate these sensors along with a mobile device so as to provide the capability of data measurement to the vast population that use mobile devices and thus create regional grid networks. The system aims to use the mobile for updating weather parameters as well to be the focal point of communication of the weather nowcasting information. As a result, the mobile device would provide targeted distribution of the weather information, which is more advantageous than the traditional means of mass distribution of information; also, as mobile technology acts as a focal point of gathering weather related parameters, it provides a twofold advantage for setting up a low cost, region specific weather monitoring 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.

This article describes how health sensors, which measure health parameters, are miniaturized to fit the size of a mobile. They aim to integrate these sensors along with a mobile so as to provide data measurement to the vast population which use the mobile, and thus, create regional grid networks. The authors aim to use the mobile for updating health parameters as well as be the focal point of communication of the health information. As a result, the mobile would provide targeted distribution of the health information, which is advantageous compared to the traditional means of mass distribution of information. Also, a mobile acts as a focal point of gathering health related parameters, it provides a twofold advantage for setting up a low-cost region-specific health monitoring system.

Geographical Maps

The increasing use of technologies like smart phones and mobile apps enables people to be actively involved in collecting data that can be the base of useful services to the whole citizenship. In the realm of volunteer data collection, this chapter addresses the problem of mobility and accessibility limitations for vulnerable citizens in today's cities. The MEP (Maps for Easy Paths) project proposes a set of tools and mobile apps for the enrichment of geographical maps with information about accessibility of urban pedestrian pathways, targeted at people with mobility problems. Different issues are considered and discussed in this chapter, including: the problem of collecting data of a user's route and of reconstructing it with novel sensor fusion techniques; the problem of correcting the positions obtained from low-cost GNSS receivers of mobile devices; the need of usable and accessible applications for the fruition of the collected data suitable for the target users.

Text Field

In the paper authors are introducing the concept of usage of physical orientation of a mobile device, calculated using built-in environmental sensors like accelerometer, gyroscope and magnetometer for detection of tilting gesture. This gesture is used as an acceptance factor for the two next probable word solutions suggested to the user during text input. By performing the device tilt, the first or second word is being automatically put into the desired text field and new prediction is performed. The text predictions are calculated and stored directly on the device to maintain privacy protection. The founding concept of the software is being presented, as well as initial considerations and further plans. This solution is recommended especially to smartphone manufacturers like Microsoft, Samsung and Apple to deploy in their latest models.

<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.

This paper focuses on the behavior of Trojan horses in mobile devices. This malicious software tries to steal information from a mobile device while the user is unaware. We describe the communication links through a Trojan horse installed into a mobile device. To demonstrate the effects of a Trojan horse infection we present a practical example on a PDA. Via SMS, the malicious user can access a user?s contacts information through the previous installation of the Trojan horse. The results show that this process means a loss of information and a quantified cost to the attacked user too. This paper proposes different solutions to avoid this malware and its effects.

Indoor Scenarios

Optical wireless LANs (OWLs) constitute an emerging networking paradigm for indoor scenarios’ fit to different smart cities’ fields of applications. Commercial products employing this technology have been made available on the market in recent years. In this work, we investigate, through a set of indoor communication experiments based on commercially available products, how different environmental and usage modes affect the performance of the system, addressing the presence of multiple users, the position and mobility of the mobile devices, the handover among adjacent cells and the effect of background lighting. Our finding shows that the system is quite robust with respect to the variation of operational conditions. We show that, in most conditions, the links can reliably sustain a stable throughput, achieving at least 50% of the throughput achieved with using the maximum light intensity of the transmitting lamp, while they are affected in a very mild way by factors like position and height of the mobile device, and virtually unaffected by variations in the background light.
