An important function for a tactile navigation system of a handheld tool, such as a surgical scalpel, is the spatial transparency of the device. This paper proposed a new tactile display that can augment touch sensation at the finger pulps without the need for a stimulator between the tool and the finger pulps. We utilized transcutaneous electrical nerve(More)
Recently, there has been considerable interest in technologies that appropriate human body parts, especially the skin, as an input surface for human-computer interfaces. Since human skin is always available and highly accessible, such on-body touch interfaces enable the control of various systems in ubiquitous environments. An interface utilizing skin as an(More)
Some kinds of substances naturally attract people to touch them. The slurry made from water and starch is one of the haptically fascinating substances, and presents the amusing but mysterious sensation like playing in the mud when you were in childhood. The mysterious haptic sensation comes from the property of the fluid, "dilatancy", which is the change in(More)
Unobtrusive tactile sensing is an important yet challenging topic for medical and robotic fields. We proposed a novel tactile sensing technology for obtaining the force of an interaction and the position at which it makes contact with an object of arbitrary shape without any mechanical obstructions. The proposed sensing method is based on electromechanical(More)
Hand motion capture is an important yet challenging topic for biomechanics and human computer interaction. We proposed a novel electrical sensing technology for capturing the finger angles from the variation of the wrist shape. The proposed device detects the signal related to the wrist-electrode contact resistances, which change according to the variation(More)
Tactile exploration of a material's texture using a bare finger pad is a daily human activity. However, modern tactile displays do not allow users to experience the natural sensations of a material when artificial sensations are presented. We propose an electrotactile augmentation technique capable of superimposing vibrotactile sensations in a finger pad,(More)
In this paper, we present a roughness modulation technique that employs electrotactile augmentation to alter material texture perception , which is conducted through mechanically unconstrained touch. A novel electrotactile augmented reality system that superimposes modulating nerve activity onto afferent nerves at the middle phalanx of a finger is(More)
Tablet PCs and smartphones rapidly become popular nowadays. People can touch objects on the touch panel display of the tablet PC or smartphone, but only get sensation of touching the surface of the display. Recently, some systems capable of inserting themselves into the display by using retractable stylus have been proposed. <i>Beyond</i> [Lee and Ishii(More)
