Abstract Optical Camouflage uses the Retro–reflective Projection Technology, a projection–based augmented–reality system composed of a projector with a small iris and a retroreflective screen. The object that needs to be made transparent is painted or covered with retroreflective material. Then a projector projects the background image on it making the masking object virtually transparent. 1.

Abstract We propose a novel display–based game environment using augmented reality technology with small robots. In this environment, the small robots can be augmented by a display image according to their positions and postures.The augmentation activity reinforces the fun of playing with such small robots in the real world.

minirobo:A Game Environment Using Small Robots with Mixed Reality
複合現実感技術と小型ロボットを用いたゲーム環境

Previous research on augmented reality has been mainly focused on augmentation of visual or acoustic information. However, humans can receive information not only through vision and acoustics, but also through haptics. Haptic sensation is very intuitive, and some researchers are focusing on making use of haptics in augmented reality systems. While most previous research on haptics is based on static data, such as that generated from C・・・

"Smart Finger" is a novel type of tactile display for Augmented Reality (AR) that is wearable, like a press-on fingernail.  This device allows the user to feel various textures while tracing his or her fingers along smooth objects. This wearable AR interface can supplement bump mapping information to real objects.

Stop Motion Goggle (SMG) expands visual perception by al- lowing users to perceive visual information selectively through a high speed shutter. In this system, the user can easily ob- serve not only periodic rotational motion such as rotating fans or wheels, but also random motion like bouncing balls. In this research, we developed SMG and evaluated the effect of SMG on visual perception of high speed moving objects. Furthermore this paper describ・・・

The Straw-like User Interface is a novel interface system that allows us to virtually experience the sensations of drinking. These sensations are created based on referencing sample data of actual pressure, vibration and sound produced by drinking from an ordinary straw attached to the system. This research of presenting virtual drinking sensations to mouth and lips is the first in the world to have been attempted, and comes with high academic e・・・

The concept of using a robot as an interface between the real and information worlds can be referred to as a Robotic User Interface (RUI). In RUI, though the robot is able to be used as an interface that has both input ans and output, the robot was actually often used only as an input device in a previous system. Against this, we develop the system that pays attention to the function of output of visual Information on RUI.

東京工業大学 ロボット技術研究会 ARMS (Artificial Reality Management Systems) Project ARMS-II at the first Inter-collegiate Virtual Reality Contest (IVRC) in 1993. A DC-motor-based haptic display and an electrical-muscle-stimulation-based haptic display for the grasping sensation were achieved. This work was chosen as a winner and the Technical Award of IVRC 1993.

BYU-BYU-View is a novel interface realized with the symbiosis of the input/output of wind and the computer graphics. "BYU-BYU" is a japanese onomatopoeia for a howling wind. It adds a new element, that is, "wind", to the direct interaction with a user and a virtual environment, and the communication through a network, by integrating the graphic presentation with the input and output of wind on a special screen.

"Chewing Jockey" augments food texture by introducing sound, based on the cross-modality effect. Users can experience munching “super” crispy potato chip, biting “live” food or eating “artificial” materials. We aim to improve eating experience to encourage healthy habits, and to make the eating process entertaining.

The amount of digital appliances and media found in domestic environments has risen drastically over the last decade, for example, digital TVs, DVD and Blu-ray players, digital picture frames, digital gaming systems, electronically moveable window blinds, and robotic vacuum cleaners. As these devices become more compatible to Internet and wireless networking (e.g. Internet-ready TVs, streaming digital picture frames, and WiFi gaming sy・・・

Fur Display makes invisible information visible. It not only delivers dynamic movements of appealing, bushy fur, but it is also a feathery, visual, tactile display that invites touch and interaction. Earlier versions of this concept often used rigid surfaces like tabletops, but Fur Display presents touchable fur with surprising dynamic movement. The device is simple and small, so it can be placed on clothing, appliances, or personal belongings, where it beco・・・

This image-processing technology stabilizes the trembling in images captured with a rotating camera in real time, and because of its "sphere" characteristics, it can track objects no matter how fast or where they are moving.

RobotPHONE is a Robotic User Interface (RUI) that uses robots as physical avatars for interpersonal communication.Using RobotPHONE, users in remote locations can communicate shapes and motion with each other. In this paper we present the concept of RobotPHONE, and describe implementations of two prototypes.

it is so much fun to hum. But to the people around you, it's just a nuisance. In this research, we propose "Silent Humming", a device that allows users to hum without people around them hearing it, much like Silent Piano and Silent Violin.

Abstract We proposed a fabrication method for stretchable sensor. The stretchable sensor consist of a photo reflector (made up of a photo transistor and an infrared LED) and a spring. The photoreflector is embedded in the spring. When the spring is not stretched, the emitted IR light will reflect back to the phototransistor. However, when the spring is stretched, some of the emitted IR light can flow out through the aperture of the spring, reducing ・・・

This paper proposes a method to detect pressure asserted on a mobile phone by utilizing the back camera and flash on the phone. There is a gap between the palm and camera when the phone is placed on the palm. This allows the light from the flashlight to be reflected to the camera. However, when pressure is applied on the phone, the gap will reduce, reducing the brightness captured by the camera. This phenomenon is applied to detect t・・・

We proposed a display technology that utilizes the phenomenon whereby the shading properties of fur change as the fibers are raised or flattened. One can erase drawings by first flattening the fibers by sweeping the surface by hand in the fiber's growth direction, and then draw lines by raising the fibers by moving the finger in the opposite direction. These material properties can be found in various items such as carpets in our living environments. W・・・
