"WiiMedia" is a study using the WiiRemote, a new consumer video game controller from Nintendo's, for media art, pedagogical applications, scientific research and innovative unprecedented entertainment systems. Normally, consumer hardwares, like standard controllers of new video game platforms, are closed to public developers. The Nintendo's WiiRemote(More)
In recent years, stereoscopic displays paired with glasses that make 3D movies possible are a popular research topic and continue to become widespread. These stereoscopic displays can create the appearance of three-dimensional images by simply wearing a pair of special glasses; however, when seen with the naked eye, the images for the left and right eyes(More)
We propose a system that enables the display of multiplex-hidden images for selected users with highly accessible polarizing filters. This system requires no electronic devices for users. It is designed with high dynamic range (HDR) projection technology and realizes the display of multiplexed content with HDR. Recently, research into HDR projection(More)
Recently, cartoon contents are applying to various media like interactive systems. In a near future, the desire of user may become to immerse their live experience into a cartoon content deeply. In automatic cartoon generation environment using NUI (Natural User Interface) like Kinect, we can comprehend the importance of linking emotion expression with(More)

This article contributes to the improvement of natural user interfaces (NUI) using depth-based kinematics recognition tools like the Microsoft Kinect. The proposed method, "AccuMotion" is comprised of tracking sequential key poses as accumulated motion. The AccuMotion recognition algorithm is based on multiple kinematics evaluation functions that evaluate(More)
We have enabled the superimposition of multiplexed images on the same screen at the same time with tangible and stable equipment. Our multiplex images can be seen by wearing special configured polarized glasses, and the image projection method is designed to be based on current 3D stereoscopic technology, which is now prevalent and making rapid progress,(More)
“Penguin Hockey”: A Tangible Playroom for Children Akihiko Shirai, Shouichi Hasegawa, Yasuharu Koike and Makoto Sato Precision and Intelligence Laboratory, Tokyo Institute of Technology. We have developed an interactive installation called "Penguin Hockey". It is a demonstration content of "Tangible Playroom" for children. Tangible playroom looks an empty(More)
