Arousing elements in children’s digital interactive storybook
This paper reports an ongoing study on making
children’s digital storybook arousing.The problem
being addressed in this paper is the lack of proper elements for guiding designers to incorporate into children’s digital storybook. Without the proper elements, designers tend to design digital storybook based on their preferences, instead of those usable to the children.This may lead to discouraging state
when children interact with the digital storybook. To address that, this paper aims at determining the most common interface components for digital interactive storybook that make children feel aroused when interacting with. In accomplishing that, a series of field study was carried out, involving a sample of interactive digital storybook.Data were collected from 13 children aged seven to nine through observation and interview.In the end, a set of most common elements that make children aroused when
interacting with interactive digital storybook were gathered

Vision-Based Apple Classification for Smart Manufacturing
Smart manufacturing enables an efficient manufacturing process by optimizing production and product transaction. The optimization is performed through data analytics that requires reliable and informative data as input. Therefore, in this paper, an accurate data capture approach based on a vision sensor is proposed. Three image recognition methods are studied to determine the best vision-based classification technique, namely Bag of Words (BOW), Spatial Pyramid Matching (SPM) and Convolutional Neural Network (CNN). The vision-based classifiers categorize the apple as defective and non-defective that can be used for automatic inspection, sorting and further analytics. A total of 550 apple images are collected to test the classifiers. The images consist of 275 non-defective and 275 defective apples. The defective category includes various types of defect and severity. The vision-based classifiers are trained and evaluated according to the K-fold cross-validation. The performances of the classifiers from 2-fold, 3-fold, 4-fold, 5-fold and 10-fold are compared. From the evaluation, SPM with SVM classifier attained 98.15% classification accuracy for 10-fold and outperformed the others. In terms of computational time, CNN with SVM classifier is the fastest. However, minimal time difference is observed between the computational time of CNN and SPM, which were separated by only 0.05 s
Investigation of fusion features for apple classification in smart manufacturing
Smart manufacturing optimizes productivity with the integration of computer control and various high level adaptability technologies including the big data evolution. The evolution of big data offers optimization through data analytics as a predictive solution in future planning decision making. However, this requires accurate and reliable informative data as input for analytics. Therefore, in this paper, the fusion features for apple classification is investigated to classify between defective and non-defective apple for automatic inspection, sorting and further predictive analytics. The fusion features with Decision Tree classifier called CurveletWavelet-Gray Level Co-occurrence Matrix (CW-GLCM) is designed based on symmetrical pattern. The CW-GLCM is tested on two apple datasets namely NDDA and NDDAWwith a total of 1110 apple images. Each dataset consists of a binary class of apple which are defective and non-defective. The NDDAW consists more low-quality region images. Experimental results show that CW-GLCM successfully classify 98.15% of NDDA dataset and 89.11% of NDDAW dataset. A lower classification accuracy is observed in other five existing image recognition methods especially on NDDAW dataset. Finally, the results show that CW-GLCM is more accurate among all the methods with the difference of more than 10.54% of classification accuracy. © 2019 by the authors
Affective computing in education: A systematic review and future research
It is becoming a trend to apply an emotional lens and to position emotions as central to educational interactions. Recently, affective computing has been one of the most actively research topics in education, attracting much attention from both academics and practitioners. However, despite the increasing number of papers published, there still are deficiencies and gaps in the comprehensive literature review in the specific area of affective computing in education. Therefore, this study presents a review of the literature on affective computing in education by selecting articles published from 2010 to 2017. A review protocol consisting of both automatic and manual searches is used to ensure the retrieval of all relevant studies. The final 94 selected papers are reviewed and relevant information extracted based on a set of research questions. This study classifies selected articles according to the research purposes, learning domains, channels and methods of affective recognition and expression, and emotion theories/models as well as the emotional states. The findings show the increased number and importance of affective computing studies in education domain in recent years. The research purposes of most affective computing studies are found to be designing emotion recognition and expression systems/methods/instruments as well as examining the relationships among emotion, motivation, learning style, and cognition. Affective measurement channels are classified into textual, visual, vocal, physiological, and multimodal channels, while the textual channel is recognized as the most widely-used affective measurement channel. Meanwhile, integration of textual and visual channels is the most widely-used multimodal channel in affective computing studies. Dimensional theories/models are the most preferred models for description of emotional states. Boredom, anger, anxiety, enjoyment, surprise, sadness, frustration, pride, hopefulness, hopelessness, shame, confusion, happiness, natural emotion, fear, joy, disgust, interest, relief, and excitement are reported as the top 20 emotional states in education domain. Finally, this study provides recommendations for future research directions to help researchers, policymakers and practitioners in the education sector to apply affective computing technology more effectively and to expand educational practices. © 2019 Elsevier Lt
Water-body segmentation in satellite imagery applying modified Kernel K-means
The main purpose of k-Means clustering is partitioning patterns into various homogeneous clusters by minimizing cluster errors, but the modified solution of k-Means can be recovered with the guidance of Principal Component Analysis (PCA). In this paper, the linear Kernel PCA guides k-Means procedure using filter to modify images in situations where some parts are missing by k-Means classification. The proposed method consists of three steps: 1) transformation of the color space and using PCA to solve the eigenvalue problem pertaining to the covariance matrices of satellite image; 2) feature extraction from selected eigenvectors and are rearranged by applying the training map to extract the useful information as a set of new orthogonal variables called principal components; and 3) classification of the images based on the extracted features using k-Means clustering. The quantitative results obtained using the proposed method were compared with k-Means and k-Means PCA techniques in terms of accuracy in extraction. The contribution of this approach is the modification of PCA selection to achieve more accurate extraction of the water-body segmentation in satellite images
Cloud-assisted gamification for education and learning – Recent advances and challenges
Gamification has gained considerable interest in education circles due to its capability of enhancing the learning process among students. In the future, it is expected that gamification will overtake the traditional way of learning resulting in issues such as scalability, upgradation of learning modules. To address these issues, merging gamification with cloud computing seems a viable solution. However, the employability of gamification through cloud computing is still in its infant stage. Hence, this article investigates the applicability of gamification through cloud computing and presents a comprehensive survey of state-of-the-art gamification in education and learning. We also identify the subject areas that can be gamified and taught using the cloud service. The critical elements and minimum requirements necessary to gamify education are also identified. Moreover, a specific cloud-assisted gamification architecture is proposed and discussed together with its possible applications. The article is concluded with the research challenges and suggestions for future work
The relationship between stingless bee and native plants studies
In the past decade, the benefits of stingless bee honey as an anticancer agent has increased
in demand in Malaysia. Despite the increasing demand, the quality produced highly
depends on a certain plant, Ixora spp. The practice of planting design in landscape
development only by considering the aesthetic values leads to the poor productivity of
stingless bee honey. Therefore, this review focuses on the suitability of native plants used
in landscapes designed for stingless bees. This study employed thematic analysis related
to the issues between native plants, stingless bee and landscape development. Based on
the assessment, literature on stingless bees discussed issues related to its habitat in the
tropical rain forest, the behaviour of finding food, characteristics of its honey and the
benefits of consuming the honey. Meanwhile, studies on native plant demonstrated the use
of plants in providing food and habitat to the local insects which contribute to the
continuity of the species. As a conclusion, the quality of honey is dependent on the
relationship between stingless bees and native plants. Hence, the native plants can be
potentially used in planting design for the improvement of stingless bee honey production
