The use of mobile phones while driving has been a hot topic in the field of driving safety for decades. Although there are few studies on the influence of gesture control on in-vehicle secondary tasks, this study aims to investigate the impact of gesture-based mobile phone use without touching while driving from the perspective of multiple-resource workload owing to visual, auditory, cognitive, and psychomotor resource occupation. A novel gesture control technique was adopted for secondary task interactions, to recognize the gestures of drivers. An experiment was conducted to study the influences of two interaction modes, traditional touch-based mobile phone interaction and gesture-based mobile phone interaction, on driving behavior in three different cognitive level task groups. The results indicate that gesture-based mobile phone interaction can improve driving performance with regard to lateral position-keeping ability and steering wheel control; nevertheless, it has no significant impact on longitudinal metrics such as driving speed, driving speed variation, and throttle control variation. Gesture-based mobile phone interactions have a larger effect on secondary tasks with medium cognitive load but not on actual operation tasks. It was also verified that the performance of gesture-based mobile phone interaction was better in secondary mobile phone tasks such as switching (e.g., switching songs) and adjusting (e.g., adjusting volume) than the traditional interaction mode. This study provides the theoretical and experimental support for human–computer interaction using gesture-based mobile phone interactive control in future automobiles.

Abstract The mobile phone, with revolutionary smart capabilities, provided its users enormous benefits, especially the convenience of shopping through websites and applications from anywhere and anytime. There are several academic studies conducted to measure the adoption and usage behavior of consumers towards mobile shopping platforms, for more than a decade. However, the research on mobile shopping behavior had gained more attention only in the last few years. The purpose of this study is to conduct a detailed and systematic review of mobile shopping literature (from the consumer behavior perspective) and perform quantitative analysis, with the help of bibliometric analysis. The study examined 158 academic articles that was obtained from Scopus, to perform bibliometric analysis, and the analysis revealed that the research on mobile shopping behavior had gained more attention between 2012 and 2018. The paper identifies the key contributions in terms of the most productive journals, countries, institutions, papers, and authors in research on consumers’ mobile shopping behavior. The co-citation reference analysis, keyword co-occurence analysis and word cloud technique had been used, to identify the evolution of various themes focused in this area. This study’s results will make researchers and scholars to have better understanding about the knowledge structure of academic research on mobile shopping through bibliometrics and visualization techniques.

Agriculture plays vital role in the economic of developing country. This paper Proposes, monitoring and access control system for greenhouse by using IOT. Our Proposed system will check for certain common conditions, for instance such as moistness, soil condition, temperature, humidity, light intensity, Carbon monoxide detection and operate the water supply through phone itself. All the environmental instance information are send to cloud server using Wi-Fi module ESP32. If any climatic condition crosses certain specific threshold limit related action will be taken place like if the temperature becomes high the rooftop of the green house will be opened or the exhaust fan will be switch ON manually by the user and if the light intensity goes down the external light supply will be given to the plants. The microcontroller will turn ON the motor if the moisture content of soil doesn’t meet the required condition. The sensors used in the proposed system are Resistive soil moisture sensor, DHT11 sensor, MQ9 sensor and LDR. The user can monitor and control parameters through mobile phone by using BLYNK app. This model was attempted in order to achieve the intelligent monitoring of greenhouse environment parameters like temperature, humidity, soil moisture etc., keeping the user continuously informed of the conditions inside the greenhouse using IOT technology.

Abstract Background: Individuals with prediabetic state are much more likely to develop Type-2 Diabetes Mellitus (TD2M) 4 times greater than those with normal glucose tolerance. Lifestyle changes such as daily physical activity and healthy diets can decrease the risk of prediabetic state . Mobile applications intervention could be one of the solutions to improve self-management awareness and compliance of prediabetic state intervention. There are no studies in systematic reviews of mobile phone applications intervention to prevent prediabetic state yet. Therefore, the objective of this study was to collect and summarize the evidence from randomized controlled trials (RCTs) exploring the effectiveness of mobile phone applications for intervention in prediabetic state patients.Methods: This protocol was prepared in accordance with the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) statement. The database that will be used includes PubMed, ProQuest and EBSCO with date restriction between January 2007 and July 2019 in English language only. Identification of articles will be done independently by three reviewers through the title of the articles, reviewing the abstract, and then the full-text-article. Any disagreement will be resolved by consensus. The quality assessment and possible risk of bias will be evaluated using forms adapted from the Jadad score. Extraction and content analysis will be performed systematically. Quantitative data will be presented graphically via forest plot with 95% confidence intervals. Where possible we will explore the heterogeneity and continue to conduct meta-analysis using RevMan software package. Discussion: Changes in lifestyle, such as daily physical activity and a nutritious diet, can help to reduce the risk of prediabetes. Mobile phone applications, including health-related applications, is demonstrated to have a lot of promise in terms of providing tailored medical recommendations. Conclusion: The proposed systematic review and meta-analyses will allow us to obtain the evidence exploring the effectiveness of mobile phone applications for intervention in prediabetic state patients.Systematic review registration: This protocol has been registered in the Prospective Registry of Systematic Review (PROSPERO) database (CRD42021243813).

Individuals with autism spectrum disorders (ASD) are often not comfortable during mobile-phone conversations with unfamiliar people. “Hugvie” is a pillow with a human-like shape that has been designed to provide users with the tactile sensation of hugging another person during phone conversations to promote feelings of comfort and trust in the speaker toward their conversation partners. Our primary aim was to examine whether physical contact by hugging a Hugvie could reduce the stress of speaking with an unfamiliar person on the phone in individuals with ASD. We enrolled 24 individuals and requested them to carry out phone conversations either using only a mobile phone or using a mobile phone along with the Hugvie. All participants in both groups completed questionnaires designed to evaluate their self-confidence while talking on the phone, and also provided salivary cortisol samples four times each day. Our analysis revealed that the medium of communication was a significant factor, indicating that individuals with ASD who spoke with an unfamiliar person on the phone while hugging a Hugvie had stronger self-confidence and lower stress levels than those who did not use Hugvie. Hence, we recommend that huggable devices be used as adjunctive tools to support individuals with ASD during telephonic conversations with unfamiliar people.

Abstract Resilience has become important in disaster preparedness and response. Unfortunately, little is known about resilience at the household level. This study presents the results of a survey into individual and household level preparedness to disaster events in Yangon, Myanmar, which is prone to natural disasters such as tropical cyclones, flooding, and earthquakes. The study aimed to understand societal resilience and to provide information that could be used to develop a holistic framework. In four different Yangon townships, 440 households were interviewed. The results of the survey indicate how risk preparedness could be improved by specific measures related to the following five factors: 1) increasing the general public’s knowledge of first-aid and its role in preparedness; 2) improving mobile phone infrastructure so that it can be used for communication during disasters, along with building up a redundant communication structure; 3) better use and organisation of volunteer potential; 4) more specific involvement of religious and public buildings for disaster response; and 5) developing specific measures for improving preparedness in urban areas, where the population often has reduced capacities for coping with food supply insufficiencies due to the high and immediate availability of food, shops and goods in regular times. The findings of this survey have led to specific recommendations for Yangon. The identified measures represent a first step in developing a more general framework. Future research could investigate the transferability of these measures to other areas and thus their suitability as a basis for a framework.

Abstract Although many technologies assume that a device or an account would be used by a single user, prior research has found that this assumption may not hold true in everyday life. Most studies conducted to date focused on sharing a device or account with the members in a household. However, there is a dearth in existing literature to understand the contexts of sharing devices and accounts, which may extend to a wide range of personal, social, and professional settings. Further, people’s sharing behavior could be impacted by their social background. To this end, our paper presents a qualitative study with 59 participants from three different countries: Bangladesh, Turkey, and USA, where we investigated the sharing of digital devices (e.g., computer, mobile phone) and online accounts, in particular, financial and identity accounts (e.g., email, social networking) in various contexts, and with different entities - not limited to the members in a household. Our study reveals users’ perceptions of risks while sharing a device or account, and their access control strategies to protect privacy and security. Based on our analysis, we shed light on the interplay between users’ sharing behavior and their demographics, social background, and cultural values. Taken together, our findings have broad implications that advance the PETS community’s situated understanding of sharing devices and accounts.
