We present a new haptic augmented reality system that modulates the perceived stiffness of a real object by changing the perceived material with vi-bratory subtraction and addition. Our system consists of a stick with a vibrotac-tile actuator and a pad with an elastic sheet. When a user taps the pad, the innate vibration resulting from the tapping is(More)
In cell fusion and genetic recombination, although the activity of single cells is extremely important, there is no method to analyze single cell activity. Development of a quick analyzing method for single cell activity is desired in various fields. Dielectrophoresis (DEP) refers to the force exerted on the induced dipole moment of an uncharged dielectric(More)
Musical video games that allow users to play expensive musical instruments in a virtual environment constitute one of the most popular genres in the field of video games. Recent developments in motion input technology have enabled users to play the instruments intuitively and immersively. However, output technology, in particular haptic feedback, is not as(More)
Characters with body materials that are different from that of humans, such as metal robots or rubber people, frequently appear in movies and comics. While the abilities of their synthetic bodies can be easily observed from their actions, their somatic sensations are more difficult to appreciate. Our aim in this work is to simulate the alteration of the(More)
Visual signs and audio cues are commonly used for pedestrian control in the field of general traffic research. Because pedestrians need to first acquire and then recognize such cues, time delays invariably occur between cognition and action. To better cope with this issue of delays, wearable devices have been proposed to control pedestrians more(More)
We present VacuumTouch, a novel haptic interface architecture for touch screens that provides attractive force feedback to the user's finger. VacuumTouch consists of an air pump and solenoid air valves that connect to the surface of the touch screen and suck the air above the surface where the user's finger makes contact. VacuumTouch does not require the(More)
Movies, comics, and video games frequently involve robotic heroes composed of metallic parts. Although these characters exist only in the realm of fantasy, many of us would be interested in becoming them, if only for a short time. The question therefore naturally arises: how would it feel to be a robot?
In this paper, we propose a novel stick-type interface, the "HaCHIStick," for musical performance on a tablet PC. The HaCHIStick is composed of a stick with an embedded vibrotactile actuator, a visual display, and an elastic sheet on the display. By combining the kinesthetic sensation induced by striking the elastic sheet with vibrotactile sensation, the(More)
In sports, dancing and playing music, it is important to achieve correct body movement as it greatly affects performance. However, matching one's movement with ideal movement is fundamentally difficult, because we do not have a detailed perception of our own body movement. In this study, we propose to present "rotary switch feeling" feedback as a new haptic(More)
Worlds of science fiction frequently involve robotic heroes composed of metallic parts. Although these characters exist only in the realm of fantasy , many of us would be interested in becoming them, or becoming like them. Therefore, we developed a virtual robotization system that provides a robot-like feeling to the human body not only by using a visual(More)
