Software Quality Requirement Analysis on Educational Game

Software Quality Requirement Analysis on Educational Game Software Quality Requirement Analysis on Educational Mobile Game with Tourism Theme Anggy Trisnadoli1*, Istianah Muslim2, Wenda Novayani3 Abstract: Mobile game is one type of game that runs on mobile devices such as smartphones and tablet PCs. In previous research, we have proposed quality model for mobile game which is a quality model that was built to measure quality from mobile games. This model was built from quality requirements that were analyzed for mobile games. Educational mobile game is education game genre with mobile based that aimed to learning, then the quality requirements maybe will different compared to other games. This research was conducted by analyzing the mobile games quality requirements that specific for educational games genre in order to generate new quality requirements that are specific to the mobile educational game. The case studies that become an evaluation of current research are the tourism of Riau province, Indonesia. So the mobile educational game that will design later is a mobile educational game that contains about tourism in Riau province. To get a list of criteria for this case, then we conducted a survey of several users, and also formed a group discussion forum along with a tourism ambassador of Riau province, so that the quality requirements will be more reliable. So the proposed quality requirements may become a reference to build a game product that has a good quality based on the users perspective. Keywords: Software quality, games, mobile games, educational mobile games, tourism, Riau province. Game is a system composed of artificial rules that involve players with the aim to entertain [1] [2]. Game contains scenarios that composed of a collection of audio and visual interest that allows users to enjoy game play that has been given by the game. By the unique characteristics game compared to other software, then, there are many things that do more specific, special for the games. Quality model for mobile game is one of the quality models that were built to measure the quality of the mobile games [3]. This model was built based play ability quality models built by Sà ¡nchez et al [4] and adapted to the quality requirements for mobile games [3]. In its application this quality model used to measure the quality of a users perspective, so that measurements can be made after the game finished mobile products developed. In designing an educational game, it must be guided by a good reference. Quality assurance can be done starting of the development stage, the design stage. Quality models for the mobile game offers a collection of properties that indicate the needs of a mobile game quality, so that the quality requirements can be used as a reference in building a good mobile game. However, that offered quality requirement is built for the mobile game in general, while the mobile educational game is a genre the mobile game with educational or learning, so that the quality requirements could have a few differences. Based on these problems, so, in this research we performed an analysis of the mobile games quality requirements that are specific to the educational games genre, to be able to produce a game product that has fit quality of the quality requirements based on the users perspective. As for the issues that will be studied in this paper are does requirements for a quality mobile game can be used as a reference in the design stage of development the mobile educational games. And how far the relationship of quality requirements for mobile game required to Mobile Educational Games with Tourism content of the users perspective to be able produce a good quality product. 2.1. Quality Requirement for Mobile Game In 2015, research on the quality model for mobile games has been conducted by Trisnadoli, Hendradjaya and Sunindyo [2] entitled A Proposal Quality Model for Mobile Games. Quality Model for Mobile Game was formed based on the software quality requirements that has been compiled based on the criteria and ideas from several researches on mobile games [3]. The proposed model has quality factors as shown on Fig. 1. Fig. 1. Quality Model for Mobile Games [2] Factors and sub factors for the quality of the quality model for mobile games that have been proposed are Usability In Use with sub factors Effectiveness In Use, Efficiency In Use, Satisfaction. Then Flexibility In Use with sub factor Accessibility. And Safety with subfactor User Health Safety Table 1. Quality Requirements for Mobile Games [3] No Quality Requirements for Mobile Games 1 Game gives a clear goal and a player can achieve goal 2 Players do not find any error in the game 3 Game can be played in a short time 4 Game easy to understand by players 5 Game has a manual (help feature) 6 Control of the game has been consistently in according with the standards 7 Games provide an appropriate response to the action of Players 8 Challenges, strategies and the steps of the game are already balanced 9 Screen layout is comfortable to be seen 10 Audio of the game was comfortable and supportive with a good game 11 Mobile devices and game interface are already suitable and appropriate 12 The experience of playing is Fun 13 Players get the appropriate reward 14 Storyline or scenario of the game is interesting 15 Players can express themselves 16 No repetition that make the game boring 17 Game control is appropriate and flexible 18 Game can accommodate the surrounding environment 19 Game supports multiple ways to play 20 Players are not affected on safety and health issues Mobile game is defined as a game played on a mobile platform-based devices are expected to increase the entertainment on the users mobile device. Mobile devices that can be applied to mobile game such as Smartphones, PDAs, Tablet PCs and Portable Game Console. Mobile game is highly dependent on the device that became his home [5]. Based on the characteristics of mobile games and mobile applications presented by several researchers [6]-[11] then performed an analysis of the characteristics and then were extracted to produce set of quality requirements are been the foundation of building a quality requirement that will be used. After conducting an analysis of data that has been collected, so, the conclusion of proposed quality requirements for mobile game can be seen in Table I. 2.2. Educational Game Genre Characteristics According to Sugihartono [12], educating means the process of changing the attitudes and behavior of a person or group with a mature effort with teaching and training efforts. Education can be obtained for both formal and informal. Formal education was obtained from a structured learning that has been designed by an institution. While the non-formal education is the knowledge gained humans in everyday life either experienced or learned from others. One way to learn with non-formal system is by educational game. Educational games are games that are designed or created to stimulate thought include improving concentration and problem-solving [13]. YM Harahap on [14] concluded that the educational game is one of the games that can be useful to support the teaching and learning process with more fun and more creative, and usable to provide teaching or increase user knowledge by an exciting media. According to Hurd and Jennings [15] declared that educational game is game that is specifically designed to teach user a certain learning, concept development and understanding and guide them in their ability to train and motivate them to play. Factors that are considered necessary in developing educational game are usability, accuracy, appropriateness, Relevance, Objectiveness, Feedback, Engagement, Motivation, and Gaming Literacy. Dondlinger [16], said that a number of distinct design elements on educational games are narrative context, rules, goals, rewards, multisensory cues, and interactivity seem necessary to stimulate desired learning outcomes. And a few other things about the characteristics of the educational game are Challenging, Fun, and Excitement not patronizing and based on experience, interactive, expertise, reflection. Determination of the quality requirements of mobile educational games, we perform an analysis based on various sources of quality requirements, such as the quality requirements that have been offered by previous researchers then combine from survey results that conducted on some respondents, while also using the functional requirements of mobile educational game stakeholders for tourism in Riau province. So that, the proposed quality requirements can become a reference in developing mobile educational game with good quality.   Ã‚   3.1. Quality Requirements for Mobile Educational Game based on Users Perspective In determining the quality requirements of mobile games from the users perspective, data collection or surveys conducted to several respondents randomly. Respondents, who being questioned are derived from various professions, age, sex, and excitement in playing the games. The stuff to consider in conducting a survey on software quality requirements analysis for mobile games are The comfort of audio and visual, Interest on the storyline, Satisfaction in playing, the comfort using control game, Screen size of mobile devices, Addictive (the desire to repeat the game). Survey of users was conducted in the form of an interview. Selection of respondents by random sampling method is applied to 130 people with different backgrounds, but still has an interest in using games on mobile devices. The interview results are then analyzed and processed by concluding and verification of data obtained. Table II is the result of the conclusions of the quality requirements of mobile games based on the users perspective. Table 2. Survey Result on Requirements from Users Perspective No Indicator Requirements 1 The comfort of audio and visual Mobile game should be good appearance The layout that is used comfortably viewed Color usage harmonious and good 2. Game Controller The buttons position is appropriate The controller usage is simple 3 Storyline Game characters are Interesting Scenario of the games are not boring The desire to repeat the game again and again Based on data that shown in Table II, and after calculation of the number of respondents who give a positive statement on the list of requirements, so the number was created in the percentage as shown in Fig. 2. Fig. 2. Survey result on requirements from users perspective by percentage 3.2. The results of the Forum Group Discussion for Riau Province Tourism Case Study Forum Group Discussion (FGD) was conducted to get a conclusion for the criteria that are required to build a mobile educational game with a case study of tourism on Riau province. This activity was attended by 35 participants that were an ambassador for tourism in Riau province. Discussions were held during few hours, then, closed with some results which can be seen in Table III. Table 3. FGD Result to Mobile Educational Game Criteria No Indicators Criterias 1 Interface Attractive appearance (eye catchy) 2 The color usage is comfortably viewed 3 Audio comfortable to hear 4 Storyline Interesting storyline or game play 5 Not boring 6 Addiction (wanted to play again-and again) 7 Education Contents Simple but meaningful Growing a curiosity From the discussion we get conclude that the most important content in game tourism theme are Arts, Tourist Attraction and Folklore. Arts with Traditional Dance, Songs and Musical Instrument. Tourist Attraction with Nature and Historical Heritage. Folklore with Legend and Fairy Tales. Table III shows the various technical criteria to be considered in the development of an interesting mobile educational game. In order to build a mobile educational game on tourism sector, there are several things to consider such as the content, simple but meaningful and interesting, and dont forget to contain about Malay art and culture, because it is a hallmark from Riau Province. As for the interface of this educational game, the things to consider are the attractive appearance, the use of color that comfortable to look at and pleasant sound to be heard. After discovering the things that become important considerations in the requirement of mobile games, educational games, also the requirement for mobile game with tourism content, then formed a new calculation to show the overlapping and interrelated requirements to be good quality requirements as a reference in designing a mobile-based game with education genre and tourism case study in Riau province. The results of the analysis are shown in Table IV. Table 4. Mapping of Quality Requirements for Mobile Educational Games with Tourism Theme Requirements Quality Requirements for Mobile Games [3] Previous Research on Educational Game Survey Result from Users Perspective FGD Result on Educational Game on Tourism Game provides a clear goals à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Game is easy to understand à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Game can be played in a short time à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Game have complete features à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Control of the game has been consistently in according with the standards à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Screen layout is comfortable to be seen à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Audio of the game was comfortable and supportive with a good game à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ The mobile device screen is appropriate to the game à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ The experience of playing is Fun à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Storyline or scenario of the game is interesting à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ No repetition that make the game boring à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Game control is appropriate and flexible à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Players gain knowledge from the game à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Game is simple but meaningful à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Content on tourism must be update à ¢Ã‹â€ Ã… ¡ Language usage appropriate to target of player à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Having educate messages behind the entertainment given à ¢Ã‹â€ Ã… ¡ à ¢Ã‹â€ Ã… ¡ Based on that Table IV, indicated that some requirements are actually owned by all sources are used, but there are some requirements that are not discussed on several sources. Especially the contents of tourism that it only required if the specific case study towards the tourism sector, would be an important thing for the preparation of quality requirements. Based on all the stages that have been done before, and then we analyze it to propose a new quality requirement. Proposed quality requirements for mobile educational game that specific to tourism case study are show on Table V. It contains the proposed quality requirements for mobile educational game with a case study of tourism. So in designing and developing mobile educational game later, these quality requirements can become one of factor to be good quality software. Because of the good quality software is start from the design stage, not only during the implementation or development, even when they are published to the user. Table 5. Proposed Quality Requirements for Mobile Educational Games with Tourism Case Study No. Quality Requirements 1 Game provides a clear goals 2 Game is easy to understand 3 Game can be played in a short time 4 Game have complete features 5 Control of the game has been consistently in according with the standards 6 Screen layout is comfortable to be seen 7 Audio of the game was comfortable and supportive with a good game 8 The mobile device screen is appropriate to the game 9 The experience of playing is Fun 10 Storyline or scenario of the game is interesting 11 No repetition that make the game boring 12 Game control is appropriate and flexible 13 Players gain knowledge from the game 14 Game is simple but meaningful 15 Content on tourism must be update 16 Language usage appropriate to target of player 17 Having educate messages behind the entertainment given Based on the analysis and evaluation, the conclusions of this research are software quality requirements especially in the game are heavily dependent on type and case studies that will be develop. Software quality requirements can be composed of any various kinds of input, not only from the existing criteria, but also can be collected based on user feedback and the specific requirements of stakeholders that will use the software. Quality requirements for mobile educational game on tourism case studies has been built specifically based on the criteria that collected to build a good quality software. The proposed quality requirements can become a reference in building software educational game design since the beginning, so the quality of mobile educational games already maintained earlier. For future research, the proposed quality requirements should be performed a validation testing on the feasibility, so that it can be more confirmed as good quality requirements. And the proposed quality requirement can be a reference to build a quality model with specific quality factors and complete metrics to evaluate the mobile educational game software, so it can measure how much the quality value of a mobile educational game in tourism theme.
