Lifelog sharing system for memory recollection

It has become easier to create a lifelog by using smart phones. Lifelogs can be used in several ways. However, some problems exist in memory recollection; as many lifelogs owned by a person are partial information, it is impractical to remember days themselves. Therefore, a lifelog sharing system for memory recollection is proposed. The system elicits related information from other peoples lifelogs to complete the system users lifelog. In this paper, the definition of the lifelog used and operations for it are shown. Then, the effect between lifelogs and memory recollection is shown. Finally, system implementation is mentioned.

Trial of Learning Support System Using Kinect in After School Care Programs

The important roles of after school care programs are protecting the lives of students whose parents are working or unable to be at home after they finish school or on school holidays and helping them create self independence. We propose a learning support system for helping after school care students. The system is used for practicing the “Kuku” multiplication table and it has been implemented using the Kinect motion capture system to recognize “air characters” written by the body actions of learners. We conducted a trial to evaluate the proposed system by asking many students in after school care programs to participate and confirmed that this system was helpful for groups of students to learn. We explain here how we implemented the system, and report the results from the trial. We also suggest the future directions of the system.

A learning support system for 9 × 9 multiplication table with Kinect

We propose a learning support system for the 9 × 9 multiplication table “KuKu” and have implemented it using Kinect motion capture to recognize “air characters” written by the body actions of KuKu learners. We explain how to implement the system, report the results of a trial with elementary school students, and suggest the future directions of the system.

A playing and learning support system using Kinect for Romaji

The use of information devices in educational settings has been increasing over the years. We propose a learning support system that is an expansion of the original Kinect system. The proposed expansion has been implemented using the Kinect motion capture system to recognize “air characters” written by the body actions of learners and is used in this study for practicing Japanese letters expressed in Romaji by a combination of alphabets. We believe that students can have fun with learning by performing body actions, thus keeping their motivation to learn high. We had some elementary school students operate the system and then evaluated the results.

Support System for Romaji Learning through Exercise

There has been a steady increase in educational learning using information devices. In Japan, Romaji is used to input text into computers and other information devices. It was developed to describe the sound of Japanese in the Roman alphabet. Therefore, learning Romaji is important for computers literacy in Japan. We developed a support system for learning Romaji through exercises using the Kinect device for elementary school students in the lower grades. The system supports students in their studies by recognizing the alphabetical characters they write in the air. We believe that students can have fun learning by performing physical actions that keep their motivation to learn high. We had some elementary school students operate the system, and the results confirmed that they studied merrily and learned new characters. The students taught and learned alphabetical characters they did not know and learned how to use our system together. Their motivation to use the system was high, and some students continued their learning experience longer than their everyday school hours. There were students who had already learned some Romaji at school and students who had not learned them at the time of the study, but they all had fun using our system and learned new Romaji they did not previously know.
