Usability testing for educational computer game using observation method

For most children the first contact with the computer is through some sort of educational game. Therefore, it is important that computer games for children are well-designed and usable for the children. In order to evaluate the usability of the computer game, children must be observed while exploring and playing the game and given the chance to express their opinions. Therefore, to involve children effectively, appropriate evaluation techniques are needed. This paper will discuss an observation method that has been adopted in a usability testing with the children. In this study, a computer game called Jelajah is chosen as the game to be tested for the usability evaluation with children. Jelajah is suitable for the experiment because it is an adventure game which is a very common game genre for children. Five preschool children aged between five and six years old are selected for this study. During the usability testing session, facilitator observes the child and fill in the observation checklist form in order to track the effectiveness and efficiency of the game. After the test session completed, the child is required to answer a simple interview-based questionnaire to know their level of satisfaction after playing the game. Data collected are both qualitative and quantitative. The collected data are analyzed to determine the levels of effectiveness, efficiency and satisfaction. The levels of effectiveness, efficiency and satisfaction are being measured by averaging them to a single metric that can represent the usability of Jelajah. The result obtained showed that the approach adopted to conduct a usability testing of a computer game with children using Jelajah can also be adopted for evaluating any educational computer game with children.

Measuring usability of educational computer games based on the user success rate

Children learn through play [1]. According to Crawford [2] educational game is the childrens first contact with the computer. Therefore, it is important that the computer games for children are well designed and usable. Usability testing can also be adopted to assess learners motivation towards learning. Assessing the usability with children requires special consideration. Children must be allowed to play freely and expressed their opinion while being observed. This study explores the measuring consideration for the usability of an educational game called Jelajah. Jelajah, was designed to teach pre-schools children to learn the Malay words and was developed based on a solid research on educational approaches. Five pre-school children were selected for this study. During the usability testing session, children are observed and their behaviors are recorded in an observation checklist. The session was video-taped for further observation. A post test was administered after the session to seek the childrens satisfaction in using the game for learning. Data collected were quantitative and qualitative data. Data were later quantified to measure the effectiveness, efficiency and satisfaction towards the software. Based on the analysis, children showed interest and were highly motivated to learn when using educational game for learning.

Real-time feedback for Jawi characters tracing activity

Tracing is one of the preliminary activities for children in the process of learning to write Jawi characters. Jawi characters tracing activities using digital technology with a real-time feedback is one of the new technologies in teaching and learning Jawi writing in which children perform tracing activities on a tablet using a stylus pen as an input of Jawi characters tracing. The tracing engine is being developed to provide a real-time feedback on the accuracy of tracing activities performed by users. The accuracy of tracing activities feedback is evaluated using a comparative analysis by looking at the agreed score between the tracing engine real-time feedback and feedback furnished by the experts. Krippendorff Alfa Coefficient of Reliability Index (Krippendorff α) agreement score is used to measure the agreement between tracing engine real-time and experts feedbacks. The outcome of Krippendorff α agreement score found that the accuracy of the feedback trace activity generated by tracing engine is almost the same as the feedback provided by experts.

Identifying the Qur’anic Segment from Video Recording

This paper describes a system to identify Quran recitation (referred as Qur’anic) segment from speech video recording using the extracted acoustic signal. Identifying the Qur’anic sequence pattern from mixed-combination of speech and Qur’anic signal will contribute to more efficient segmentation of video segments. The random forest classifier algorithm is employed to classify the dynamic pattern of the extracted audio. Two feature sets which are pitch and intensity are extracted from the audio, and constructed into sequence of speech patterns which then classified as Qur’anic or non-Quranic segments. A collection of 40 segmented videos were trained and compared with the segmented videos which have been segmented manually. This project achieves classification accuracy of 57% using pitch and 85% using intensity. While using pitch feature only, 85% of the identified segments match the manually segmented collection while using intensity feature gives 95% match accordingly).

Embedding Watermarking in Malaysia Halal Logo Using Spread Spectrum Watermarking

Digital watermarking is a process whereby arbitrary information is encoded into an image in such way that the additional payload is imperceptible to the image observer. In the modern era, providing authenticity is becoming increasingly important as more of the world’s information is stored as readily transferable bits. Halal is an Arabic word which means lawful or permissible by Islamic laws. Halal logo is an image given by JAKIM to companies that have been issued Halal certificates. The companies need to produce the logo on their product packages and it is optional to display the halal logo on their websites. However, the Halal logo in the digital form used is not specific to one company and they can simply copy and alter it from other sources. Hence this matter causes the confusion on ensuring the authenticity of the Halal logo displayed on the websites of companies. Thus, a prototype applying watermarking using spread spectrum technique is developed to ensure authenticity of the Halal logo. This prototype has successfully embeds the watermark in the Halal logo image and several tests were done to ensure the system is working. Comparisons between texts files, images, sizes and histograms are conducted. In conclusion, by applying watermarking in Halal logo, the authenticity of it is assured and it is hoped to discourage and probably prevent people or companies to claim their product as Halal without receiving the Halal certification.
