We propose a mind map manipulation system, named MMVR. This system allows multiple users to edit a mind map by using hand gestures and to share it in virtual reality space. To implement the system, we leveraged a hand gesture tracker for quick, easy, and correct handling of mind map elements and a head-mounted display (HMD) for providing a wider workspace than a standard PC's screen. We conducted...
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...
Having students ask and answer questions among themselves can help deepen their understanding of learning content. Tablet devices are advantageous for such application due to their portability and capability to support not only text but also images and sound. A few elementary schools in Japan have already started introducing tablet devices into the classroom. This requires making some changes to the...
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...
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.
Network Address Translation (NAT) is one of the solutions against IPv4 address shortage. They sometimes prevent the acts of Peer-to-Peer aplications. Session Traversal Utilities for NATs (STUN) is one of the solutions and it is effective for many kinds of NATs. However, symmetric NAT, a kind of NAT, does not applied STUN. We implement a extension of STUN to apply it for symmetric NAT, and also measure...
