Focused Ultrasound for Tactile Feeling Display
نویسندگان
چکیده
We studied on the feasibility of focused ultrasound for tactile feeling display. Our experiments showed that focused ultrasound at 1 MHz and 5 MHz effected our somatic sensation both by its radiation pressure and by direct stimulation to the nerve structures. The radiation pressure force generated by our apparatus was 0.23 gf/cm per 1-watt power consumption and evoked tactile feeling stably, while direct nerve stimulation could not induce stable tactile feeling.

Compact Device for Markerless Hand Tracking and Noncontact Tactile Feedback
A compact device is introduced which enables users not only to operate computers by moving their hands in mid-air but also to feel haptic feedback on their hands. The device consists of a depth camera for hand tracking and a noncontact tactile display for haptic feedback. The tactile display utilizes focused ultrasound to produce tactile stimulation from a distance. The principles are described...
متن کاملA Cutaneous Perception Model and Its Examination by Ultrasound Tactile Display
We propose a tentative tactile perception model called Simple Bundle Model and examine it by a tactile display based on ultrasonic radiation pressure. The ultrasonic tactile display reproduces high-resolution stress patterns with wide bandwidth on the skin. It is a multipurpose device for synthesizing high-fidelity tactile feeling, and useful to clarify the human tactile perception. The prototy...
متن کاملAdding Tactile Reaction to Hologram
In this paper, a hologram with tactile reactions is presented. The developed system consists of three components; a holographic display, a hand tracker, and a tactile display. The tactile display, which is our original device, produces force on user’s bare hand without any contact by using radiation pressure of airborne ultrasound. It adds the sense of touch to optical images floating in mid-ai...
متن کاملVirtual Surface Characteristics of a Tactile Display Using Magneto-Rheological Fluids
Virtual surface characteristics of tactile displays are investigated to characterize the feeling of human touch for a haptic interface application. In order to represent the tactile feeling, a prototype tactile display incorporating Magneto-Rheological (MR) fluid has been developed. Tactile display devices simulate the finger's skin to feel the sensations of contact such as compliance, friction...
متن کاملRoughness Feeling Telepresence System with Communication Time-Delay
A framework of tactile telepresence systems has been proposed in the present paper, which enables active touch with time-delay communication between a tactile sensor side system and a display side system. In the framework, a tactile display system can apply tactile stimuli to fingers of an operator in syncronization with touch motions based on physical parameters of objects which are estimated ...
