Abstract

A method and apparatus for determining sensory threshold information for a shoe-type device, the shoe-type device, and a method of controlling the shoe-type device are disclosed. The method of determining sensory threshold information includes executing a program for sensory threshold testing, determining sensory threshold information of a user based on a choice input by the user that is received in a process of the sensory threshold testing, and transmitting the determined sensory threshold information to the shoe-type device.

First claim

What is claimed is:

1. A method of setting sensory threshold information for a wearable device included in a shoe worn by a user, the method comprising:
controlling a graphical user interface (GUI) of terminal device to display an interface screen requesting user input from the user to begin a sensory threshold test;
performing the sensory threshold test on the user in response to receipt of the user input to begin the sensory threshold test, the performing the sensory threshold test including,
performing a first test by instructing the wearable device to provide a stimulus to the user while controlling the GUI such that an intensity of the stimulus provided to the user increases while the GUI displays an instruction on the interface screen requesting the user receiving the stimulus to provide a selection input indicating when the user senses the stimulus provided by the wearable device during the first test, and
performing a second test after the first test by instructing the wearable device to provide the stimulus to the user while controlling the GUI such that the intensity of the stimulus provided to the user during the second test increases at a different rate from the intensity of the stimulus provided to the user during the first test while the GUI displays an instruction on the interface screen requesting the user provide a second selection input indicating when the user senses the stimulus provided by the wearable device during the second test, wherein a second rate of change in the intensity of the stimulus applied to the foot of the user during the second test is less than a first rate of change in the intensity of the stimulus applied to the foot of the user during the first test;
determining the sensory threshold information of the user based on the intensity of the stimulus provided to the user at a time when the second selection input was received from the user during the second test; and
transmitting the sensory threshold information to the wearable device.

2. The method of claim 1 , wherein the determining of the sensory threshold information comprises:
determining a sensory threshold value for each of a left foot and a right foot of the user.

3. The method of claim 2 , wherein the determining of the sensory threshold information comprises:
determining the sensory threshold value for each of a forefoot and a rearfoot of the left foot of the user, and a forefoot and a rear foot of the right foot of the user.

4. The method of claim 1 , wherein a reference sensory threshold value is set to a level of the intensity of the stimulus provided to the user at the time when the selection input was received from the user during the first test, and
a final sensory threshold value for a foot of the user is set based on a level of the intensity of the stimulus provided to the user at the time when the second selection input was received from the user during the second test.

5. The method of claim 4 , wherein the performing of the first test comprises:
transmitting, to the wearable device, a control signal instructing the wearable device to apply a test vibration to a current sole portion among a plurality of sole portions of the foot of the user;
receiving an input from the user indicating a selected one of the plurality of sole portions; and
determining whether the current sole portion corresponds to the selected one of the plurality of sole portions.

6. The method of claim 5 , further comprising:
randomly selecting a next sole portion to receive the test vibration from among the plurality of sole portions, in response to the current sole portion corresponding to the selected one of the plurality of sole portions.

7. The method of claim 5 , further comprising:
transmitting, to the wearable device, a control signal instructing the wearable device to again apply the test vibration to the current sole portion, in response to the current sole portion not corresponding to the selected one of the plurality of sole portions.

8. The method of claim 7 , wherein an initial intensity of the test vibration applied to the current sole portion is based on an intensity of the test vibration most recently applied to the current sole portion.

9. The method of claim 4 , wherein the performing the second test comprises:
repeatedly performing the second test to obtain a plurality of sensory threshold values; and
determining the final sensory threshold value based on the plurality of sensory threshold values.

10. The method of claim 4 , wherein the performing of the first test comprises:
determining an intensity of a test vibration in a range between a minimum intensity and a maximum intensity; and
transmitting, to the wearable device, a control signal instructing the wearable device to apply the test vibration of the determined intensity to the foot of the user through a vibrator of the wearable device.

11. The method of claim 10 , wherein the determining of the intensity of the test vibration comprises:
increasing the intensity of the test vibration, in response to not receiving the input from the user.

12. The method of claim 4 , wherein the performing of the second test comprises:
transmitting, to the wearable device, a control signal instructing the wearable device to apply a test vibration to a current sole portion among a plurality of sole portions of the foot of the user based on the reference sensory threshold value;
receiving an input from the user indicating a selected one of the plurality of sole portions; and
determining whether the current sole portion corresponds to the selected one of the plurality of sole portions.

13. The method of claim 12 , further comprising:
randomly selecting a next sole portion to receive the test vibration from among the plurality of sole portions, in response to the current sole portion corresponding to the selected one of the plurality of sole portions.

14. The method of claim 12 , further comprising:
transmitting, to the wearable device, a control signal instructing the wearable device to again apply the test vibration to the current sole portion, in response to the current sole portion not corresponding to the selected one of the plurality of sole portions.

15. The method of claim 14 , wherein an initial intensity of the test vibration applied to the current sole portion is based on an intensity of the test vibration most recently applied to the current sole portion.

16. The method of claim 4 , wherein the performing of the second test comprises:
determining an intensity of a test vibration based on the reference sensory threshold value; and
transmitting, to the wearable device, a control signal instructing the wearable device to apply the test vibration of the determined intensity to the foot of the user through a vibrator of the wearable device.

17. The method of claim 16 , wherein the determining of the intensity of the test vibration comprises:
increasing the intensity of the test vibration, in response to not receiving the input from the user.

18. The method of claim 1 , wherein the transmitting of the sensory threshold information comprises:
transmitting the sensory threshold information to the wearable device via Bluetooth communication.

19. A method of operating a wearable device included in a shoe worn by a user to provide a stimulus to the user, the wearable device configured to communicate with a terminal device, the terminal device including a graphical user interface (GUI), the method comprising:
receiving, from the terminal device, sensory threshold i
