This paper proposes a novel 'Visuo-Haptic Display' using a Head-Mounted Projector (HMP) with X'tal Vision optics. Our goal is to develop the device which enables an observer to touch a virtual object just as it is seen. We describe the detail design of an HMP with X'tal Vision, which is very suitable for Augmented Reality. For instance, the HMP makes… (More)
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.
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.
A new type of Haptic AR system, SmartTouch, is introduced. SmartTouch is composed of a thin electro-tactile display and a sensor mounted on the skin. The sensed information is converted to tactile sensation through electrical stimulation. Thus, the wearer not only makes physical contact with an object, but also can " touch " surface information of any… (More)
"panavi," a recipe medium, supports cooking experience for domestic users to master professional culinary arts in their kitchens by managing temperature and pan movement properly. Utilizing a sensors-embedded frying pan--providing projected images, LED indications, and vibration--wirelessly connected with a computer system that shows text messages with… (More)
We present an actuated handheld puppet system for controlling the posture of a virtual character. Physical puppet devices have been used in the past to intuitively control character posture. In our research, an actuator is added to each joint of such an input device to provide physical feedback to the user. This enhancement offers many benefits. First, the… (More)
Although texture mapping is a common technique for adding apparent surface detail to 3-D objects, it lacks the capability to represent the motion parallax effect. So the mesh to which it is applied limits its realism. In this paper, we propose Parallax Mapping, a simple method to motion parallax effects on a polygon. This method has very fast per-pixel… (More)
Numerous robots have been developed, and some of them are already being used in homes, institutions, and workplaces. Despite the development of useful robot functions, the focus so far has not been on user interfaces of robots. General users of robots find it hard to understand what the robots are doing and what kind of work they can do. This paper presents… (More)
An electrocutaneous display system composed of three layers is implemented for augmentation of skin sensation. The first layer has electrodes on the front side of a thin plate, the second has optical sensors on the reverse side of the plate, and the third is a thin film force sensor between the other two layers. Visual images captured by the sensor are… (More)
In this paper, we present a high speed optical motion capture method that can measure three dimensional motion, orientation, and incident illumination at tagged points in a scene. We use tracking tags that work in natural lighting conditions and can be imperceptibly embedded in attire or other objects. Our system supports an unlimited number of tags in a… (More)
