Abstract

Provided is a tactile sensation recognition device according to an embodiment of the disclosure including: a receiver configured to receive tactile sensation information obtained by sensing a surface of an object through a tactile sensor; a preference determiner configured to determine whether a user prefers the received tactile sensation information, based on a user tactile function f user (x); and a display displaying a user preference for the received tactile sensation information.

First claim

What is claimed is:

1. A tactile sensation recognition device comprising:
a receiver configured to receive, from a server via a communication network, tactile sensation information;
a tactile sensor configured to sense a surface of an object of standard samples;
a display configured to display a user preference for the received tactile sensation information;
a processor configured to
generate a user tactile function f user (x) of a user by using the tactile sensor,
determine whether a user prefers the received tactile sensation information, based on the user tactile function f user (x); and
display, on the display, the user preference for the received tactile sensation information based on the determination on the received tactile sensation information,

wherein the processor is configured to generate the user tactile function f user (x) of the user by:
generating sensed tactile sensation information on the surface of the object; and
machine-training the user tactile function f user (x) using a user's preference result on the sensed tactile sensation information, and

wherein the sensed tactile sensation information includes at least one of a pressure change, temperature, hardness, a frictional force, roughness, and a surface shape.

2. The tactile sensation recognition device of claim 1 , wherein the processor is further configured to
match the received tactile sensation information with the sensed tactile sensation information on the standard samples that is most similar to the received tactile sensation information, and
determine the user preference for the received tactile sensation information based on the user tactile function f user (x) of the sensed tactile sensation information matched with the received tactile sensation information.

3. The tactile sensation recognition device of claim 1 , wherein,
when the object is clothing made of one or more materials, the processor is configured to display a first user preference for at least one of the one or more materials constituting the clothing.

4. The tactile sensation recognition device of claim 3 , wherein
the processor is configured to display the first user preference for the at least one of the one or more materials by overlapping the first user preference with an image of the clothing, and a location at which the first user preference overlaps the image corresponds to a location of a material from which the received tactile sensation information is sensed.

5. A tactile sensation recognition system comprising:
a first terminal comprising a transmitter configured to transmit tactile sensation information; and
a second terminal comprising
a receiver configured to receive, from the first terminal via a communication network, the tactile sensation information;
a tactile sensor configured to sense a surface of an object of standard samples;
a display configured to display a user preference for the received tactile sensation information;
a processor configured to
generate a user tactile function f user (x) of a user by using the tactile sensor,
determine whether a user prefers the received tactile sensation information, based on the user tactile function f user (x) of the user, and
display, on the display, the user preference for the received tactile sensation information based on the determination on the received tactile sensation information,

wherein the processor is configured to generate the user tactile function f user (x) of the user by:
generating sensed tactile sensation information on the surface of the object; and
machine-training the user tactile function f user (x) using a user's preference result on the sensed tactile sensation information, and

wherein the sensed tactile sensation information includes at least one of a pressure change, temperature, hardness, a frictional force, roughness, and a surface shape.

6. The tactile sensation recognition system of claim 5 , wherein the first terminal further comprises:
a memory configured to store a plurality of user tactile function f user (x)s for each user; and
a first processor configured to manage each user preference for tactile sensation information based on the plurality of user tactile function f user (x)s.

7. The tactile sensation recognition system of claim 6 , wherein the first processor is further configured to predict the each user preference for tactile sensation information for a surface of an arbitrary object, based on the plurality of tactile function f user (x)s.

8. The tactile sensation recognition system of claim 5 , wherein the processor of the second terminal is further configured to
provide a tactile sensation information request interface, on the display, for enabling a user to request tactile sensation information for a portion of a surface of a first object sensed by the first terminal.

9. A tactile sensation recognition method, the tactile sensation recognition method executed by a tactile sensation recognition device comprising a receiver, a tactile sensor, a processor, and a display, the tactile sensation recognition method comprising:
receiving, through the receiver, tactile sensation information;
sensing, by the tactile sensor, a surface of an object of standard samples;
generating, by the processor, sensed tactile sensation information on the surface of the object;
machine-training, by the processor, a user tactile function f user (x) using a user's preference result on the sensed tactile sensation information;
determining, by the processor, whether a user prefers the received tactile sensation information, based on the user tactile function f user (x); and
displaying, through the display, a user preference for the received tactile sensation information based on the determination on the received tactile sensation information,
wherein the sensed tactile sensation information includes at least one of a pressure change, temperature, hardness, a frictional force, roughness, or a surface shape
wherein the determining comprising
matching, by the processor, the received tactile sensation information with the sensed tactile sensation information on the standard samples that is most similar to the received tactile sensation information, and
determining the user preference for the received tactile sensation information based on the user tactile function f user (x) of the sensed tactile sensation information matched with the received tactile sensation information.
