Agile Beeswax: Mobile App Development Process and Empirical Study in Real Environment

Mobile application development is a highly competitive environment; agile methodologies can enable teams to provide value faster, with higher quality and predictability, and a better attitude to deal with the continuous changes that will arise in the mobile context application (App), and the positive impact of that on sustainable development through continuous progress. App development is different from other types of software. For this reason, our objective is to present a new agilebased methodology for app development that we call Agile Beeswax. Agile Beeswax is conceived after identifying the mobile development process’s issues and challenges, and unique requirements. Agile Beeswax is an incremental, iterative development process composed of two main iterative loops (sprints), the incremental design loop and the incremental development loop, and one bridge connecting these two sprints. Agile Beeswax is structured in six phases, idea and strategy, user experience design, user interface design, design to development, handoff and technical decisions, development, and deployment and monitoring. One of its main strengths is that it has been created with academic and business perspectives to bring these two communities closer. To achieve this purpose, our research methodology comprises four main phases: Phase 1: Extensive literature review of mobile development methodologies, Phase 2: Interviews with mobile application developers working in small to medium software companies, Phase 3: Survey to extract valuable knowledge about mobile development (which was carefully designed based on the results of the first and the second phases), and Phase 4: Proposal of a new methodology for the agile development of mobile applications. With the aim of integrating both perspectives, the survey was answered by a sample of 35 experts, including academics and developers. Interesting results have been collected and discussed in this paper (on issues such as the development process, the tools used during this process, and the general issues and challenges they encountered), laying the foundations of the methodology Agile Beeswax proposed to develop mobile apps. Our results and the proposed methodology are intended to serve as support for mobile application developers.Spanish Government European Commission RTI2018-096986-B-C3

Validation and Psychometric Properties of the Gameplay-Scale for Educative Video Games in Spanish Children

The knowledge of evaluation instruments to determine the level of gameplay of schoolchildren is very important at this time. A systematic review has been carried out in this study. The aim of this paper is to investigate the psychometric properties of a study of a sample of Spanish gamers. Two hundred and thirty-seven children (mean age: 11.2 +/- 1.17 years, range: 10-12 years, 59.5% female) completed the Gameplay-Scale to discover their opinions after a game session with a serious educational game. The final scale consisted of three factors. The fit for factor 1 (usability) was 0.712, the fit for factor 2 was 0.702 (satisfaction), the fit for factor 3 was 0.886 (empathy) and the overall fit was 0.868. A positive and direct relationship could be observed between all the dimensions of the developed scale. The greatest correlation strength is shown between satisfaction and empathy (r = 0.800; p < 0.005), followed by satisfaction and usability (r = 0.180; p < 0.05) and the association between empathy and usability (r = 0.140; p < 0.05). In summary, the results of the present study support the use of the Gameplay-Scale as a valid and reliable measure of the game experience of youth populations. These results demonstrate strong psychometric properties so that the Gameplay-Scale appears to be a valid instrument for children in different contexts where an educational video game is used, analyzing its usability/“playability” in terms of learning to use it, game satisfaction, and empathy.This research is supported by the Andalusian Research Program under the project P11-TIC-7486 co-funded by FEDER, together with TIN2014-56494-C4-3-P and TEC2015-68752 from the Spanish Ministry of Economy and Competitiveness and FEDER also

General Architecture for Development of Virtual Coaches for Healthy Habits Monitoring and Encouragement

Good health is the result of a healthy lifestyle, where caring about physical activity and nutrition are key concerns. However, in today’s society, nutritional disorders are becoming increasingly frequent, affecting children, adults, and elderly people, mainly due to limited nutrition knowledge and the lack of a healthy lifestyle. A commonly adopted therapy to these imbalances is to monitor physical activity and daily habits, such as recording exercise or creating custom meal plans to count the amount of macronutrients and micronutrients acquired in each meal. Nowadays, many health tracking applications (HTA) have been developed that, for instance, record energy intake as well as users’ physiological parameters, or measure the physical activity during the day. However, most existing HTA do not have a uniform architectural design on top of which to build other applications and services. In this manuscript, we present system architecture intended to serve as a reference architecture for building HTA solutions. In order to validate the proposed architecture, we performed a preliminary evaluation with 15 well recognized experts in systems and software architecture from different entities around world and who have estimated that our proposal can generate architecture for HTA that is adequate, reliable, secure, modifiable, portable, functional, and with high conceptual integrity. In order to show the applicability of the architecture in different HTA, we developed two telemonitoring systems based on it, targeted to different tasks: nutritional coaching (Food4Living) and physical exercise coaching (TrainME). The purpose was to illustrate the kind of end-user monitoring applications that could be developed. Keywords: telemonitoring; healthy habits; virtual coaches; system
