Activity Recognition for Risk Management with Installed Sensor in Smart and Cell Phone

Today, using communications devices such as simple and smart mobile phones has led man to face EMFs more. Thus is essential, measuring and comparing the emitted EMFs of simple mobile phones with that of smart phones. The EMFs of 2 simple mobile phones and 2 smart phones were measured by EMFs measurement portable equipment model HI-3603 in a ringing mode. Ultimately, the difference between electric and magnetic fields in simple and smart phones was evaluated by the ANOVA statistical test. The means of the electric fields of simple and smart mobile phones was 2.38±0.18 v/m and 1.9±0.18 v/m respectively. The means of magnetic fields of simple and smart mobile phones was 0.49±0.13 mG and 0.48±0.1 mG, respectively. The ratio of the mean of electric field in simple and smart phones to the standard limit (53.8 v/m) was 4.42% and 3.53% and also the ratio of the mean of electric field in simple and smart phones to the standard limit is 25.12% and 24.61%, respectively. Despite the fact that the mean of electric and magnetic fields of simple mobile phones is more than smart ones, the ANOVA statistical analysis shows that there is no significant difference between these two means (P value > 0.05). Despite the fact that EMFs in simple and smart phones are approximately equal or less than the standard limits, the safety notes shall be considered while using each of these devices.

The study investigated how mobile phones have been used for teaching and learning purposes in higher learning institutions in Tanzania. Specifically the study assessed how mobile phones facilitated the teaching and learning process, identified the mobile phone applications used for teaching and learning, determined the types of learning activities facilitated through mobile phones and assessed the common limitations of m%lea rning in at Sokoine University of Agriculture (SUA). The study employed a survey where teaching staff and students from faculties and institutes hosting academic programmes were involved. A total of 30 teaching staff and 40 students were randomly selected and included in the study. In%depth interviews, observations and questionnaire were used for data collection. It was found that majority of the respondents used their mobile phones for teaching and learning process. It was found that most respondents reported to use traditional mobile learning applications including text messages and calls. Few respondents had smart phones with a number of m%learning applications most of them being teaching staff. These were able to create upload, download and share academic resources through their smart phones while others recorded and stored files in their phones. It was also found that among teaching staff many were not aware of the capacity of their mobile phones such that they underutilized them. Costs associated with downloading multimedia content was another constraint which limited some respondents especially students from using phones for learning purposes. More than that, users were forced to use SMART/VISA cards for buying online mobile applications of which most respondents were not aware of.

Recently, smart phones have become a shining star in the mobile phone market, and the services provided by smart phones have significantly increased due to the advancements in hardware development and the great variety of user interfaces. Also, the stress of modern life has given more and more importance to the recreation and game industries. Therefore, this study aims to integrate a smart phone with a digital game so that the player can have the feel of real actions and enjoy the interaction during the game. By combining a digital game with a physical device, i.e., a mobile phone, the game player is provided with a richer gaming experience in which the mobile phone serves more than as a phone, and the game is more than tapping at a keyboard or clicking a mouse. The digital game in this study is about fishing. The fishing games on the market are typically played with a keyboard or a mouse, which nevertheless makes the games quite different from the real fishing experience. For example, the existing fishing games can hardly simulate the action of casting a fishing rod or reeling in the fish on the hook. In this study, a simulated setting is designed to mimic real situations so that digital interaction between the human and the computer in a human-computer interface can be assessed. A digital interactive game including both hardware and software is designed in this study, and whether the interactivity and the human-computer interface of the interactive game are acceptable by players is studied. According to questionnaire survey results, most players give positive evaluation to the combination of the mobile phone (i.e., hardware) and the digital game (i.e., software), and the more interactive the human-computer interface is, the stronger the interest and the greater the pleasure a player will feel in playing the game. Suggestions on how to improve the hardware and software design are also provided.

We show how modern mobile phones (Weiser's tabs) can interact with their environment, especially large situated displays (Weiser's boards). Smart phones' emerging capabilities are fueling a rise in the use of mobile phones as input devices to such resources as situated displays, vending machines, and home appliances. Mobile phones' prevalence gives them great potential to be the default physical interface for ubiquitous computing applications. We survey interaction techniques that use mobile phones as input devices to ubiquitous computing environments. We use smart phone to describe an enhanced mobile phone. Our analysis blurs the line between smart phones and PDAs such as the Palm Pilot because the feature sets continue to converge.

The property of the mobile phone is taking important role to choose it. In the present situation, exploring, comparing and analyzing the important properties of regular mobile phone(feature phone) and smart phone are very meaningful study. Therefore, the survey was carried out to get the properties of feature phone and smart phone and analyze the difference of those phones. And proposed the important variables for customer satisfaction which must be given priority. The result showed that 'design' and 'Quality' are important to both mobile phone user groups. The problems with mobile phones currently in use were 'poor performance' to feature phone users and 'expensive charge' and 'poor A/S' to smart phone users. Two groups also showed significant difference with the customer satisfactions, and smart phone user group showed higher satisfaction. For smart phone user group, four factors are induced from the properties but 'Hardware Quality' (representing 'call Quality', 'A/S', 'Convenience to use', 'Battery life') and 'Design & Function'(representing 'Internet', 'Convergence Functions', 'Design, 'Color') have significant and positive effects on Customer Satisfaction.

The survey sample consisted of 150 smallholders randomly selected from a total of 241 smallholders in the Duong No Ward, Hue City of Vietnam. Descriptive and inferential statistics were used to analyse the data. The research results revealed that a number of ICT tools were used by smallholders. Of which, televisions, mobile (smart) phones, and internet-connected computers were the most commonly used by smallholders. The study also indicated that mobile (smart) phones and internet-connected computers were the two types of ICT tools that had the highest effectiveness for flower marketing. The research found that there was a statistically significant relationship existing between the extent of ICT use (mobile phones) in flower marketing and the smallholders’ educational level (χ² = 7.009; p = 0.002), income (χ² = 6.341; p = 0.053), distance from home to electricity base (χ² = 4.385; p = 0.044), and participation in training programs (χ² = 7.748; p = 0.009). The local government and authorities need to provide supportive policies, training courses, and technological infrastructure investment to improve access to and use of ICTs in flower production and marketing.

Background: Mobile phones are no longer simply a communication device now-a-days, rather has become an indispensable part of human life. Mobile phones have transformed from necessity to the level of status symbol. Smart phones are a newer generation of cellular phones with integrated computer related functions capable of performing various tasks based on number of applications. The extensive use of smart phones in recent years had led to exposure of human beings to radio frequency electromagnetic field (RF-EMF) which could have adverse effects on sleep. Objectives of the study was to compare the effects of mobile phone on quality of sleep in smart phone users and non- users using Pittsburgh Sleep Quality Index (PSQI). 2. To educate the study subjects about the hazards of excessive smart phone usage. Methods: Study design- Prospective cross- sectional comparative study. Study subjects- 166 working class adults working in various offices in Bhopal. Inclusion criteria - Those who were using any type of mobile phones and gave consent to participate in the study. Exclusion criteria -Those who had any recent trauma or chronic illness related to sleep. Ethical consideration-Permission taken from Head of the department of Community Medicine, Gandhi Medical College, Bhopal. Verbal consent was obtained from the study participants. Results: Out of 166 study participants 92 were male and 74 were female of which mostly belonged to the age group of 20-30 years with mean 26.75 years and SD 5.12years. 97.6% were graduate and above. Participants showing a better subjective sleep quality amongst non-users of smart phone was significant (p=0.00185) and the number of participants showing no problem to keep up enough enthusiasm to get things done were more in non-users than users with difference being statistically significant (p=0.0146). Conclusions: We should restrict the use of mobiles to minimum for sound mind and good health.

36 Purpose Each year, more than 200,000 children globally are diagnosed with cancer, more than 80% of which occurs in low- to middle-income countries. Pediatric cancer survival rates in low- to middle-income countries are 5% to 25% compared with 80% in high-income countries, with treatment abandonment accounting for one third of the survival gap. A mobile case management system can improve patient communication and reduce treatment abandonment. The current proposal evaluated the feasibility and acceptability of a mobile phone–based case management system at Bugando Medical Centre (BMC) in Mwanza, Tanzania. Methods We surveyed 40 families of children with cancer who attended BMC and 10 pediatric oncology providers at BMC to assess mobile phone ownership, use patterns, communication preferences (eg, voice v text messaging), and the advantages and disadvantages of a mobile case management system. Results In all, 85% of families owned a mobile phone and 100% of providers owned smart phones. Of families, 98% wanted to communicate with a health care provider regarding treatment support using a mobile phone, 92% wanted to receive laboratory results via mobile phone, 95% wanted to receive reminders of upcoming appointments, and 88% wanted to receive educational information on cancer via mobile phone. Of providers, 100% thought that it would be useful to use a mobile phone to communicate with patients, share laboratory results, and view standardized pediatric treatment protocols and checklists. Conclusion Most families of pediatric patients with cancer at BMC use mobile phones, with high interest in using mobile technology to communicate with providers. This increases the likelihood of success for a mobile case management platform that is aimed at reducing the abandonment of care among pediatric patients with cancer.

Taiwan is a country with fairly high mobile phone or smart phone penetration. By 2009, Taiwan's mobile phone penetration was hovering near 110%. By 2014, more than 70% of Taiwanese over age 15 owned a smart phone. However, some Taiwanese are not yet accepting of this new technology, the smart phone, for diverse reasons. Some prefer using only landline telephones; some use a traditional mobile phone but prefer landline for contacting their family and friends. Some Taiwanese use both a landline and a smartphone but still prefer the landline. In addition, cell phone-only consumers are increasing in Taiwan, especially among the younger generation. Rogers' “Diffusion of innovations” is a theory that seeks to explain how, why, and at what rate new technology or new ideas spread through societies. The technology acceptance model (TAM) is another information systems theory which investigates how users accept and use a technology. In the technology acceptance model, some factors like Perceived usefulness (PU) and Perceived ease-of-use (PEOU) influences attitudes, intention to use and actual use of a new technology. Nonetheless, not all change is necessarily healthy for all consumers. The innovation resistance of a consumer can be viewed as another perspective for studying how and why a society or some consumers accept or refuse a new technology. Based on TAM and innovations resistance perspectives, the researcher studied what are the distinguishing characteristics of those preferring a landline vs. the smartphone? How can these different consumers be reached? What is their usage of internet, landline and smartphones? Thus in this study, the researcher launched two phone surveys, one sample via landline and another sample via mobile phone, interacting with more than 1,000 respondents in each sample. The population in Taiwan exceeds 23,000,000. The researcher used a CATI (Computer-Assisted Telephone Interviewing) system to get RDD (Random Digital Dial) phone numbers for both samples and made them representative of the population. In addition, the researcher used the participant observation records by auditing the survey process to further investigate the characteristics of Taiwanese who prefer landlines or prefer cell phones and smartphones.

Ambulatory cell phone injuries in the United States: An emerging national concern

The fast development of mobile services in China and the recent trend of touch-screen handheld devices precipitate researchers to understand user experience with mobile Chinese handwriting input (HWI). This research attempts to provide an integrated picture of user experience with Chinese HWI on touch-screen mobile phones. Five usability experts were invited to inspect usability problems of seven handwriting-enabled mobile phones, which varied in type of screens, writing tools and interaction approaches, operation systems, and handwriting recognizers. In a following usability evaluation with five novice users, we collected both quantitative data and qualitative data to give an overall performance assessment to the seven mobile phones and furthermore to analyze the usability issues with HWI. As a result, we identified 16 usability issues related with handwriting recognizers, input interfaces, and devices/users respectively.

Vision based technology such as motion detection has long been limited to the domain of powerful processor intensive systems such as desktop PC's and specialist hardware solutions. With the advent of much faster mobile phone processors and memory we are now seeing a plethora of feature rich software being deployed onto the mobile platform. Since these high powered smart phones are now equipped with cameras, it has become feasible to combine their powerful processors and the camera to support new ways of interacting with the phone. However, it is not clear whether or not these processor intensive visual interactions can in fact be run at an acceptable speed on current mobile handsets. In this paper we look at one of the most popular and widespread mobile smart phone systems; the Symbian s60 and benchmark the speed, accuracy and deployability of the three popular mobile languages. We test a pixel thresholding algorithm in, C++, Python and Java and rank them based on their speed within the context of intensive image based processing.

Since the 1990s, studies on internet addiction and mobile phone addiction have been concerned. Of which, internet addiction refers to internet surfing via personal computers, and mobile phone addiction is usually set within the phone calls and sending short message. In recent years, the time and frequency people using mobile phones have been increasing rapidly with the popularity of smart phone and the development of mobile Internet. Some severe cases show an excessive use of mobile phone, even dependent or addictive symptoms. These results in a variety of physical, psychological and social problems of the individuals. However, today's mobile phone dependence or addiction is beyond the scope of calling and texting, but more on the use of the network function. So it needs to redefine this behavior addiction and its criteria by combining both internet addiction and cell phone addiction. It is named as mobile internet addiction. The definition would help to study the mechanism of the development of mobile internet addiction, and provide theoretical foundations for developing effective intervention strategies. Key words: Internet addiction; Mobile phone addiction; Mobile phone network addiction
