In most common methods of tactile presentation on touch screen, the tactile display was directly attached or contacted onto the screens. Therefore, the tactile display must be transparent so that it does not obstruct the view of the screen. On the other hand, if the tactile sensation is presented at the back of the device, the tactile display does not need(More)
In our previous study, we found that a normal DC motor can be used for vibro-tactile and pseudo-force presentation. In the present study, we developed a new vibration actuator using a DC motor that can generate much stronger vibrations than a normal DC motor and produce very low frequency of vibrations. We proposed that the stator of the motor could be used(More)
It is known that our touch sensation is a result of activities of four types of mechanoreceptors, each of which responds to different types of skin deformation; pressure, low frequency vibration, high frequency vibration, and shear stretch. If we could selectively activate these receptors, we could combine and present any types of tactile sensation. This(More)
This paper describes a novel music entertainment system that draws on auditory, tactile and visual senses. HapTONE presents players with high-fidelity vibrotactile sensations, not only after pressing the keyboard but also during the pressing operation itself. We developed keyboard type instrument that composed of key unit which is structured a vibrator and(More)
A physical button that is mounted in a mouse, a keyboard, or a shutter of a camera, provides both force and tactile feedback when a user presses it. It is certainly that users can recognize the press and input through the sensation of "click" vibrations. Many mechanical mechanisms for presenting a click sensation in a physical button have been proposed,(More)
Various systems for hand tool skill training have been developed in the domain of haptic displays. These systems typically present force to a learner's palm by directly actuating the tool. However, this approach is sometimes ineffective because learners have difficulty sensing the haptic feedback from the tool when they are holding it tightly. Thus, we(More)
