This paper reports on two experiments we conducted to look at how to design effective linear and circular apparent-motion displays. Using a two-tactor array on the upper arm, the first study found that a time interval of greater than 400 ms before repeating the directional sequence is required for subjects to achieve 95 % proficiency of direction identification over a range of duration of stimulus...
We propose a novel display technique that presents information with different visibility to multiple users. The system projects information on a screen through a revolving linear polarizer in front of the projector, and it shows information through another polarizer in front of the userpsilas viewpoint. The brightness of the observed information is reduced according to the relative angle of the polarization...
This paper describes a highly efficient transmission system for digital broadcasting redistribution services using IPTV technique. For basic requirements of IP redistribution services, we propose highly efficient compression scheme, SI (service information) multicasting scheme and a robust IP transmission scheme. A prototype system is implemented based on the proposed scheme, and its performance is...
This paper proposes a highly efficient redistribution service for digital broadcasting including high-definition video and data over IP networks. A prototype system is implemented based on the proposed scheme, and its performance is evaluated.
This paper proposes a method of extracting skeleton interactively for 3D character animation. A skeleton is automatically and interactively generated from the object data of 3D models in a process that consists of five steps: 1) transformation into a low polygon model from the original model composed of a large number of polygons; 2) calculation of the sum of the geodesic distance from specific points...
