Exploring children experience with educational mobile technology

The purpose of this study is to explore and analyse the user experience (UX) of Arabic educational and entertainment applications designed for children aging 8–10 years. This paper reports the results of an experimental study conducted on a sample of 53 children in two elementary schools in Qalqilya and Nablus, Palestine. The context of the current study is different from previous studies that were conducted in a western environment in terms of knowledge, awareness, demographic changes and background variables. Qualitative methods captured the enjoyable and attractive parts of the software being used. The qualitative content analysis showed that participants’ enjoyment using the system was quite different. During sessions, children showed much excitement and interest while working with the math app more than the science app. However, girls were less interested to use the math application compared with their use of the device itself. Following Hassenzahl’s model, the descriptions of UXs were also categorised into two categories: pragmatic and hedonic; the functionality, technical and ease of use aspects of UX of both the tablet and the math application were categorised as pragmatic. Enjoyable, exciting, confusing and upsetting experiences were categorised as hedonic. Male participants were more familiar with the use of mobile devices than female participants. The results of the present study showed that gender, culture and religion are important factors that affect children’s experience to use new technological devices since three female participants were reluctant to use the tablet especially due to cultural and religious factors.

BEHAVIORAL INTENTION TOWARDS APPLICATION-BASED SHORT-DISTANCE DELIVERY SERVICES ADOPTION IN INDONESIA

Although online shop is small in scale, this type of business gives a significant impact for the economy. In order to support online shop to develop, improvement in delivery and logistic system is needed. One of the improvements in these aspects is the emergence of application-based short-distance delivery services. Unfortunately, these applications have not been widely adapted by the online shops in Indonesia. Thus, this study tries to explore what factors can influence online shops’ decision to use these apps by implementing the unified theory of acceptance and use of technology (UTAUT). This study employed structural equation model to test the model and 5 hypotheses proposed, processed by Lisrel 8.8. The result shows that the ease of use aspect of the apps will only be relevant if it is deemed to be beneficial for the user. Moreover, the cognitive aspect also plays the role, as users tend to compare the acquired benefit with the cost incurred in using the app. As a conclusion, effort expectancy, performance expectancy and price value have a significant influence towards use behavior. On the other hand, social influence is not significantly influencing use behavior. Implications and limitations will also be discussed on this paper.

Pattern lock and the app based on context, ease of use aspect in comparison

Smartphone has been a popular device utilized to support productivity in human life and has become an integral part of human activities such as for communication, entertainment and social interaction. Those activities can be related to the information which needs to be protected because of its high privacy. Therefore, the smartphone needs a procedure that demonstrates an ability to secure that user information. However, more protective the scheme, more difficult the usage. Based on that pattern behavior, a good security scheme which support the users for easy security feature is urgently needed. One of such kind security features is authentication feature. In that manner, the ease of use aspect for acquiring the system by using an easy authentication mechanism becomes critically important. The ease of use intended is the efficiency of interaction between the user and that security feature for doing authentication including the time needed for doing that. This study developed the app which utilizes the context data, namely Geofilock. The context data meant is the location data based on the GPS and MAC address of the Wi-Fi. The system detected both context data and determined whether the smartphone needs to show the pattern screen lock as authentication feature or not, based on the context data analysis. The functionality of Geofilock works properly as shown by less user interaction number and less time needed by the user for obtaining the access. In addition, the app is easy to operate, as suggested by the user feedback.

Building a doorbell for deaf people: Motivational electronic experiment for freshmen

Renewed emphasis on (capstone or cornerstone) design courses and application of educational and learning researches are just two of the changes that Engineering Education has been through recently. Despite the many possible approaches in Inductive Learning, the fact is that students’ expectations of teaching, learning and technology have hardly changed over the years. This paper presents a lab experiment on assistive technology for deaf people to help build freshmen motivation and to address electronics concepts as early as possible in an engineering course. Learner satisfaction was evaluated by a 16-item questionnaire completed by 67 students from two distinct undergraduate programs. Learner satisfaction was assessed as a set of four dimensions: ‘Content’, ‘User Interface’, ‘Ease of Use’ and ‘Enthusiasm and Motivation’, all evaluated in a seven-level Likert Scale (ranging from ‘strongly disagree’ to ‘strongly agree’). Reported scores of ‘agree’ or ‘strongly agree’ Likert-scale options are 77%, 62%, 56%, and 76%, respectively, for ‘Content’, ‘User Interface’, ‘Ease of Use’ and ‘Enthusiasm and Motivation’ dimensions. We believe that similar scores on related dimensions are good tokens of the overall consistency of the results. In summary, students seem satisfied with the doorbell lab experiment, but improvements should be made on user interface and ease of use aspects in future versions of the experiment.

VISUALIZATION OF VGI DATA THROUGH THE NEW NASA WEB WORLD WIND VIRTUAL GLOBE

GeoWeb 2.0, laying the foundations of Volunteered Geographic Information (VGI) systems, has led to platforms where users can contribute to the geographic knowledge that is open to access. Moreover, as a result of the advancements in 3D visualization, virtual globes able to visualize geographic data even on browsers emerged. However the integration of VGI systems and virtual globes has not been fully realized. The study presented aims to visualize volunteered data in 3D, considering also the ease of use aspects for general public, using Free and Open Source Software (FOSS). The new Application Programming Interface (API) of NASA, Web World Wind, written in JavaScript and based on Web Graphics Library (WebGL) is cross-platform and cross-browser, so that the virtual globe created using this API can be accessible through any WebGL supported browser on different operating systems and devices, as a result not requiring any installation or configuration on the client-side, making the collected data more usable to users, which is not the case with the World Wind for Java as installation and configuration of the Java Virtual Machine (JVM) is required. Furthermore, the data collected through various VGI platforms might be in different formats, stored in a traditional relational database or in a NoSQL database. The project developed aims to visualize and query data collected through Open Data Kit (ODK) platform and a cross-platform application, where data is stored in a relational PostgreSQL and NoSQL CouchDB databases respectively.

However the integration of VGI systems and virtual globes has not been fully realized. The study presented aims to visualize volunteered data in 3D, considering also the ease of use aspects for general public, using Free and Open Source Software (FOSS).
