Rotary Control Interface based on Movement Modulation of Palm-Silhouette
    User interfaces using users’ own shadow or silhouette have enabled users to access to a display from distant position. These interfaces archive only a trigger operation, have no volume adjustment operation. We focus on Pesudo-Haptic physiological phenomenon which makes a user feel something like touch sensation by presenting visual different movement of what he/her identifies as his/her self body. Our goal is to realize a new silhouette interface system suited for adjustment operation, which makes a user feel sense of resistance on one’s hand by imposing movement restrictions with palm-shadow that have visuo-tictile interactions. We construct a test system that renders palm-silhouette of restricts rotation movement. This research describes results of experiments about cognitive effects of movement restriction. Finally, we discuss strategy to design volume adjustment in shadow interface.

PALMbit-Silhouette: Superimposing Palm-Silhouette to Access Distributed Large Displays
    Many recent studies of distributed-display environments discuss how to augment large workspaces with mixed reality technology. In addition to overcoming the difficulty of directly touching virtual ob jects located where a user cannot touch them in such large space environments, the usability of a distant access interface, which determines the total usability of the hard-to-reach ob jects, is the key issue in these studies. In this research, we first discuss the metaphor of a shadow cast by a user’s palm and extend it to a media as a user interface in augmented environments. Then, we introduce a new intuitive accessing method using hand gestures by image recognition. The proposed system, PALMbit-Silhouette, provides a distant user interface that enables a user to move an icon among distributed large displays with natural grasp-and-release gestures. Experiments with a prototype system showed that it enabled users to interact seamlessly with virtual ob jects in distributed-display environments.

PALMbit - A PALM Interface with Projector-Camera System -
    We propose a ubiquitous projector-camera system,“ PALMbit ”, that enables the user to input several control events using the palm of his or her hand and to output graphic information. In the proposed system, we developed an I/O method for operating digital appliances, i.e., an optical projection onto the palm of the user, which is registered by image processing, and a gesture interface based on finger movements. By projecting CG images of a virtual remote controller onto the palm of the user, the user is able to operate digital equipment intuitively using his/her own mental body image and haptic feedback.

The Opening-and-Closing Speed Control of an Elevator Door by Frequency-Shaping ILQ Design Method
    This research suggests a modeling and design for opening-and-closing speed control of an elevator door using ILQ design method with frequency-shaping function (FSILQ). A door opening-and-closing control system is designed by applying this method to a very low order reduced model. High performance of the resulting control system is obtained through proper modeling, simulation and repetitive experiments. It is confirmed that an inevitable vibration of the door speed due to model uncertainty can be suppressed by proper shaping of the frequency response of the closed loop transfer function from noise to output. The resulting control system is evaluated by applying ramp inputs as well as step inputs. As a result, the proposed control system has been verified to show robustness for a wide range of weight of door panels.
