The purpose of this study was to find the effective way of composition in terms of UX(user experience) when configuring UI(user interface) of educational game by utilizing ET(eye-tracking). Experimental material was a game related to the middle school 'force and motion'. SMI (SensoMotoric Instruments)' iView X TM RED was used in order to collect eye movement data. The results of this study was as follows. First, the lead element for fast visual attention should be placed in the center when the educational game UI is configured. Second, burton that changes character's features and the information about them should be placed close to each other. Third, learning quiz caught visual attention faster when it was placed on the left side of UI. Fourth, when one UI was overlapped by another, parts that were not overlapped was fixated, too.

In this paper, we propose an algorithm for an alternative method using the clustering algorithm in a system that needs classification to extract individual user context information. In the conventional user classification system, the user has to input his own information. In this paper, we will research and develop a system applying a clustering algorithm which can extract user 's perceived information applying the improved algorithm for user management base. Generally, the algorithm that distinguishes users with the same data makes sure that recorded information matches the newly entered information, and then responds accordingly. However, it is troublesome to manually input information of the new user. Therefore, in this paper, we propose a method to distinguish users by using the clustering algorithm based on the analyzed data from the working memory in the accumulated system without directly inputting the user information. The study shows that the management method applied to the applied algorithm is more adaptive in environments where the number of people is different from that of the existing system (as a subjective observer test method).

In recent decades, focuses on usability and emphases on user-centric design have become more prevalent in the field of software design. However, it is not always easy for engineers and computer scientists to think in the users' shoes. Human-computer interaction (HCI) is a field of study that focuses on creating technologies easier and more intuitive for the users. This paper is based on teaching HCI skills to undergraduate computer science students in a software application design course. Specifically, this paper employs: first, the HCI skills taught to the students; second, the tendencies and challenges of the students in creating user-centric applications; and lastly, suggestions based on our findings to promote HCI in developing user-friendly software. While more firm conclusions shall be reserved for more formal empirical studies, the findings in this paper still offer implications and suggestions for promoting user-centric approach for software designers and developers in the technology industry.

Today, the paradigm of education is changing from teacher-centered, facility-centered, supplier-centered to student-centered, people-centered, and user-centered. In 2019, the Ministry of Education promoted the school space innovation project to provide a school space as a balanced life space, such as learning, play, and rest, through educational activities led by students, who are the leaders of the future society. Based on this, Incheon Metropolitan City Office of Education prepared a manual for practice while carrying out a project to build a future classroom. In those projects 'user participatory design' is applied as a new design approach and facilitators play an important role as experts in the process of user participatory design. However, it is different from the guidelines by the Ministry of Education in terms of facilitator role; facilitator in Incheon's future classroom projects can be in charge of designer part. This was possible because the design scope was limited to the classroom space and the construction permit work was not applied, and the Incheon Metropolitan City Office of Education seems to be able to successfully implement the plan derived through 'user participatory design' under the responsibility of the facilitator. However, this may be considered to be inconsistent with the basic purpose of the school space innovation project. In the case of the school unit project, it is considered that more systematic supplementation is necessary.

Kinect sensors have the ability to recognize the behavior and voice of the user. Due to its low-cost and high accessibility, Kinect sensors have been used in various fields, including healthcare, education and so on. In this paper, we propose to use Kinect in piano education. Specifically, the proposed method first recognizes the coordinate values of user's posture, compares them with coordinate values of teacher's posture and provide real-time feedbacks to the user. This enables user to keep the correct posture even when he is learning piano without a teacher. However, since the piano education is a long process, it is difficult to achieve the correct posture as a teacher immediately. Thus, we propose a user-oriented method to measure the error tolerance rate. The proposed method is the first feedback based piano education system that uses Kinect sensors.

This paper proposes a robot driving system and sensor implementation for use with an education robot. This robot has multiple functions and was designed so that children could use it with interest and ease. The robot recognizes the location of a user and follows that user at a specific distance when the robot and user communicate with each other. In this work, the robot was designed and manufactured to evaluate its performance. In addition, an embedded board was installed with the purpose of communicating with a smart phone, and a camera mounted on the robot allowed it to monitor the environment. To allow the robot to follow a moving user, a set of sensors combined with an RF module and ultrasonic sensors were adopted to measure the distance between the user and the robot. With the help of this ultrasonic sensors arrangement, the location of the user couldbe identified in all directions, which allowed the robot to follow the moving user at the desired distance. Experiments were carried out to see how well the user's location could be recognized and to investigate how accurately the robot trackedthe user, which eventually yielded a satisfactory performance.
