Will reading habit influence your life? Many say yes. Reading user centered system design is a good habit; you can develop this habit to be such interesting way. Yeah, reading habit will not only make you have any favourite activity. It will be one of guidance of your life. When reading has become a habit, you will not make it as disturbing activities or as boring activity. You can gain many benefits and importances of reading.

Goals and Strategies of a Problem Based Learning Facilitator

Lack of motivation and of real-world relevance have been identified as reasons for low interest in science among children. Game-based learning and storytelling are prominent methods for generating intrinsic motivation in learning. Real-world relevance requires connecting abstract scientific concepts with the real world. This can be done by situating learning processes in real-world contexts, and by bridging the virtual content and the real world with augmented reality (AR). We combined these ideas into a Science Spots AR platform on which context-aware storytelling science learning games can be created. As proof-of-concept we developed and evaluated Leometry game, which contains geometry problems based on the Van Hiele model. This paper’s contributions are as follows: (1) concept and architecture of Science Spots AR, (2) design and implementation of the Leometry game prototype, and (3) mixed-method formative evaluation of Leometry with 61 Korean 5th grade elementary school children. Data retrieved by questionnaires and interviews revealed that the students appreciated Leometry despite its minor shortcomings, that the platform’s concept is feasible, and that there is potential for building science learning games. These results are useful to educators, computer scientists, and game designers who are interested in combining context-aware learning, AR, and games.

User Experience in Mobile Augmented Reality: Emotions, Challenges, Opportunities and Best Practices

The aim of this study was to investigate videos as potential triggers of behavior. Therefore, we applied the theories of triggers and media richness to learn about the triggering efficiency of mobile marketing videos on participants’ behavioral intentions. The experiment involved three distinct test groups, each comprising 41 student participants. From the perspective of media richness theory, we observed that the different kinds of videos had quite similar effects in terms of triggering behavioral changes. However, the mechanisms explaining why triggers were present differed for each video. Further, the results reveal that the consumer's position in the information search process was the most significant reason for the triggering of any kind of effect. In addition, the instructionally designed videos were able to exert an affective triggering effect: the more participants liked the video, the more it affected their participation intention and recall scores. This study extends the media richness research by demonstrating that the effects of media richness can vary within technically similar videos, as they form different logical connections among non-verbal visual cues related to a video's storyline.

Triggering effects of mobile video marketing in nature tourism: Media richness perspective

In this paper, we propose the mLUX framework, a model based on the user-centered design (UCD) framework, which is specifically for the development of m-learning applications. We present the results of four case studies conducted to develop m-learning applications in which the proposed mLUX framework was applied. The main goal of the proposed mLUX framework is to ensure that the stakeholders, especially students, recognize that m-learning applications are learning media that fulfill their essential educational requirements. We begin by reviewing the literature on the contributions to mobile learning usability made in various conferences and journals from 2002 to 2010. This review helped identify and recognize the methodology used to develop mobile learning applications during this period. Based on the literature review, as the empirical case studies, four m-learning applications are examined to demonstrate the performance of the proposed framework for the development of m-learning applications. We apply three distinct measurement criteria to assess the performances of the mLUX framework. This paper also argues that emotional factors, such as the user’s enjoyment, adjustability, and reliability, are significant design issues in m-learning.

mLUX: Usability and User Experience Development Framework for M-Learning

-- The user’s emotional involvement plays an important role in adopting new technologies. The level of engagement with and adoption of new digital applications depends on various personal, contextual, and emotional factors. In our study, we assessed the personal factors, such as gender differences, of perceiving and adopting technologies such as virtual reality (VR), augmented reality (AR), and conventional video. Furthermore, we assessed what kind of emotions are involved in and invoked by the context of new technologies. This is a quantitative study in which students were asked to perform experiments on VR, AR, and conventional videos. After the experiments, participants were asked to fill out a predefined survey about their emotional reactions to the experiments. The results show, unlike the prior research, that female participants were more enthusiastic about the usage of new technologies than males. The user experience of VR, AR and conventional videos triggered more positive emotions among females than males. For practitioners, the results  suggest that the audio-visual technologies could engage more females than males. For academics, this study provides further research on how to trigger users to adopt new audio-visual technologies .
