Title Tactile information conversion device, tactile information conversion method, tactile information conversion program, and element arrangement structure UPDATE_EN meetings
Abstract The purpose is to provide a device, method and program for tactile information conversion, and an element arrangement structure for presenting a plurality of types of stimuli that are capable of presenting a plurality of types of stimuli at one point in a concentrated manner from different points. One of the features is to determine a first stimulation point at which a first type of tactile stimulus is generated or generate the first type of tactile stimulus at the first stimulation point via the output unit and output tactile information for generating a second type of tactile stimulus via the output unit to the output unit at a second stimulation point separated within a temporally and/or spatially predetermined threshold value from the first stimulation point of the first type of tactile stimulus that has been determined or generated by a first stimulation unit.
Outline of related art and contending technology BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a tactile information conversion device, a tactile information conversion method, a tactile information conversion program, and an element arrangement structure.
2. Description of the Related Art
In the related art, tactile sensation presentation devices have been developed that present a tactile sensation for a real or virtual object to a user.
For example, Patent Document 1 discloses a pen-type force sensation presentation device that presents, by allowing for motions such as a reciprocating motion, a swinging motion, a tilting motion, a rotation, and the like at a movable part where a fingertip touches when a user holds the device, proprioception to the fingertip.
In addition, Non-Patent Document 1 discloses a tactile sensation presentation device that creates a tactile map using pressure, vibration, and temperature as elementary tactile sensations and synthesizes the element tactile sensations so as to present an arbitrary tactile sensation.
In addition, Non-Patent Document 2 discloses that a vibrator provided on the nail side is vibrated at the time of a finger stroking operation in a real environment so as to present a virtual sense of unevenness.
In addition, Patent Document 2 discloses an electrical tactile sensation display provided with an electrode substrate provided with a plurality of stimulation electrodes, a conductive gel layer between the stimulation electrodes and the skin, etc., in order to present electrical stimulation to the user.

Scope of claims [claim1]
1. A device worn on a human body of a subject person allowed to perceive tactile information, comprising:
a first stimulation unit and a second stimulation unit, wherein
the first stimulation unit generates a first type of tactile stimulus at a first stimulation point on the human body, the second stimulation unit generates a second type of tactile stimulus at a second stimulation point on the human body,
the first stimulation point and the second stimulation point are spatially and/or temporally separated within a predetermined threshold value,
the second type of tactile stimulus is a type of tactile stimulus with a temporal or spatial physiological discrimination threshold that is larger than that of the first type of tactile stimulus, to cause the subject person to perceive the first type of tactile stimulus and the second type of tactile stimulus at the first stimulation point on the human body.

[claim2]
2. The device according to claim 1, wherein
the first type of tactile stimulus and/or the second type of tactile stimulus is one of force, vibration, temperature, and electricity.

[claim3]
3. The device according to claim 1, wherein
the first stimulation point and/or the second stimulation point is a perceptual point which is generated by phantom sensation illusion.

[claim4]
4. The device according to claim 1, wherein
the first type of tactile stimulus and/or the second type of tactile stimulus is detected by an input unit including a multipoint distribution type pressure sensation measurement sensor on a surface layer, a warm/cold feeling measurement sensor in an intermediate layer; and a vibration feeling measurement sensor in a lower layer and is generated based on information transmitted through communication.

[claim5]
5. The device according to claim 1, wherein
the first type of tactile stimulus and/or the second type of tactile stimulus is presented by an output unit including a distribution-type pressure presentation unit using an electrical tactile sensation stimulus on a surface layer, a high-speed driving type warm/cold feeling presentation unit using a Peltier element in an intermediate layer, and a vibration presentation unit of a wide frequency range in a lower layer.

[claim6]
6. A structure adapted to be provided on a human body of a subject person allowed to perceive tactile information, comprising:
one or a plurality of first elements and a one or a plurality of second elements, wherein
the first element generates a first type of tactile stimulus at a first stimulation point on the human body in the vicinity of the first element,
the second element generates a second type of tactile stimulus at a second stimulation point on the human body in the vicinity of the second element,
the first stimulation point and the second stimulation point are spatially and/or temporally separated within a predetermined threshold value,
the second type of tactile stimulus is a type of tactile stimulus with a temporal or spatial physiological discrimination threshold that is larger than that of the first type of tactile stimulus, to cause the subject person to perceive the first type of tactile stimulus and the second type of tactile stimulus at the first stimulation point on the human body.

[claim7]
7. The structure according to claim 6, wherein
the first element and the second element are laminated on each other, and
the second element is arranged more toward the body than the first element.

[claim8]
8. The structure according to claim 6, wherein
the first type of tactile stimulus or the second type of tactile stimulus includes at least vibration,
when the first elements or the second elements include a plurality of elements that generate vibration as tactile stimulus,
the elements that generate vibration are arranged horizontally across gaps therebetween.

[claim9]
9. The structure according to claim 6, wherein
the first elements include elements that generate temperature or vibration as tactile stimulus,
the second elements include elements that generate electricity as tactile stimulus, wherein
