User experience improvement of japanese language mobile learning application through mental model and A/B testing

Advances in smartphone technology have led to the strong emergence of mobile learning (m-learning) on the market to support foreign language learning purposes, especially for the Japanese language. No matter what kind of m-learning application, their goal should help learners to learn the Japanese language independently. However, popular Japanese m-learning applications only accommodate on enhancing reading, vocabulary and writing ability so that user experience issues are still prevalent and may affect the learning outcome. In the context of user experience, usability is one of the essential factors in mobile application development to determine the level of the application’s user experience. In this paper, we advocate for a user experience improvement by using the mental model and A/B testing. The mental model is used to reflect the user’s inner thinking mode. A comparative approach was used to investigate the performance of 20 high-grade students with homogenous backgrounds and coursework. User experience level was measured based on the usability approach on pragmatic quality and hedonic quality like effectiveness (success rate of task completion), efficiency (task completion time) and satisfaction. The results then compared with an existing Japanese m-learning to gather the insight of improvement of our proposed method. Experimental results show that both m-learning versions proved can enhance learner performance in pragmatic attributes. Nevertheless, the study also reveals that an m-learning that employs the conversational mental model in the learning process is more valued by participants in hedonic qualities. Mean that the proposed m-learning which is developed with the mental model consideration and designed using A/B testing is able to provide conversational learning experience intuitively

A new perspective of refractive error calculation with mobile application

In many situations, not standardized and limited access to eye health care in several regions of Indonesia becomes the main challenge for myopia patients to measure and monitor their current refractive error condition. Many apps were proposed to provide low-cost alternative measurement tools rather than expensive tools such as Phoropter with Snellen chart and Retinoscopy, but still, those apps need an Internet connection and manually complex steps to operate. These conditions make myopia patients reluctant to use this kind of service. In this regard, we propose an intuitive diopter level measurement app based on mobile application setup, which implements the concept of measure the user face to smartphone screen distance for the rapid diopter calculation processes and at the same time provides a low-cost alternative refractive measurement tool. This paper highlights our experiences when developing a mobile application that can help patients with myopia measuring their blur line distances and evaluate their diopter levels independently. We conduct a number of human trials with the device on a controlled environment to demonstrate the ability of the proposed app to measure the diopter level. The experimental results show that the proposed app is quite successful in measuring the diopter level of myopia patients with a relatively small range of calculation errors compared to optometrist measurement results

This is a new agency that has a playground as one of the core businesses. Along from the beginning of the playground operates until the end of July 2019, playground revenue has gradually decreased. This issue arises due to the bad condition of the grass on the playground causing local people are not willing to visit that place. The playground's grass requires special watering treatment but BUMDESMA is the lack of income so they cannot afford to pay the professional grass maintenance services to actively watering the playground grass. From these problems, We proposed an IOT based garden watering system to reduce BUMDESMA expenditure costs. The garden watering management system uses a mobile application as a user interface to control the system and embedded devices for the watering mechanism. Blackbox testing of the proposed system shows that all the functional requirements are 100% valid. Usability testing shows a value of 72 which is more than the minimum threshold of usability criterion means that the application is acceptable to users. The results of cost-efficiency testing show that the proposed water systems can reduce the cost when compared to using professional watering services

An alternative m-learning scoring approach to automatically evaluate Iqro’s pronunciation based on pitch, volume, and rhythm features

The Iqro’ has been proven as an effective method to improve literacy for reading Hijaiyah letters which are the fundamental skill for reading the Qur’an. The Iqro method relies on a mentor to evaluate the accuracy of the student’s pronunciation of the Hijaiyah letters. With the advancement of mobile technology, many mobile apps are available to assist the learning process. However, the existing solution that is available on the market only provides a one-way learning experience where users only focus on enhancing vocabulary, writing, and reading ability with a simple true-false assessment. Although enhancing the vocabulary and reading ability is important, training the correct Makhraj (Arabic pronunciation) is also essential in fundamental Hijaiyah learning. This paper presents the feasibility investigation of the usage of the pitch, volume, and rhythm as the more comprehensive audio assessment parameters in the voice recognition module to evaluate the student's ability to pronounce the Hijaiyah letter in an m-learning implementation. Instead of just presenting the true-false output, the proposed method will calculate the Makhraj correctness in the range 0 to 100. Experimental results with 10 respondents show that the sample correlation coefficient using Pearson between a manual assessment by Ustaz and the application result for Iqro’ level 1 is 0.51 which means this approach is acceptable for future implementation
