DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of preferred embodiments of the present invention will be given with reference to the accompanying drawings. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In the present specification, when any one element 'transmits' data or signals to another element, the element can transmit the data or signal directly to the other element, and through at least one other element Data or signal can be transmitted to another component.

1 is a diagram showing a VR cognitive rehabilitation training system for improving cognitive ability of the elderly with mild cognitive impairment according to an embodiment of the present invention.

Referring to FIG. 1, the VR cognitive rehabilitation training system for improving the cognitive ability of the elderly with mild cognitive impairment includes a smart block 100, a PC 200, a VR interface module 210, and an HMD 300. Here, the HMD 300 is provided with a virtual reality (VR) image from the VR interface module 210 of the PC 200 via wired or wireless communication, by being worn by a user corresponding to the elderly having a mild cognitive impairment .

To this end, the smart block 100 includes various sensors and provides information to the VR interface module 210 of the PC 200 through wired or wireless communication by defending the information of the user's touch and the surrounding environment.

Here, the PC 200, the VR interface module 210, and the HMD 300 are shown as separate components. However, the PC 200, the VR interface module 210, and the HMD 300 may be formed as one piece worn by the user.

2 is a diagram showing a configuration of a smart block 100 used in a VR cognitive rehabilitation training system for improving cognitive ability of the elderly with mild cognitive impairment according to an embodiment of the present invention. Referring to FIG. 2, the smart block 100 includes an IR sensor 112, a proximity sensor 113, an IMU 114, a FSR (pressure sensor) 115 to vigorously use the VR or rehabilitation content, The vibration motor 116 and the like are manufactured and the smart block 100 is held by a user's hand so that the VR image is displayed on the HMD Express the situation.

More specifically, the controller 130 detects the phase of the user in the surrounding environment in which the smart block 100 is installed through the IR sensor 112, and generates the position value of the smart block 100.

The control unit 130 waits for a touch input to one of the plurality of installed FSRs 115 in order to receive an external force from a user from the outside. When receiving the touch input signal, The position and the touch pressure of the FSR 115 corresponding to the touch input signal are measured.

The controller 130 also generates a distance measurement value by measuring the distance to another object located in the vicinity of the smart block 100 from the proximity sensor 113. [

The control unit 130 then determines whether the user measured by the FSR 115 is in the smart block 100 using the wireless communication such as the Bluetooth module 160 or the wired communication such as the serial communication module 170. [ , The position value of the block measured by the IR sensor 112 and the position value of the object near the block measured by the proximity sensor 113 to the VR interface module 210 of the PC 200 send.

Then, the VR interface module 210 of the PC 200 realizes the sensing information such as the method of the user holding the smart block 100 and the position of the smart block 100 in real time on the three-dimensional image of the VR content.

Here, it is preferable that the VR contents are programmed by matching with the design of the smart block 100 in consideration of the age, hand size, muscle strength, and degree of affliction of the user.

3 is a reference view showing the structure of the FSR 111 installed in the smart block 100 used in the VR cognitive rehabilitation training system for improving the cognitive ability of the elderly with mild cognitive impairment of FIG. That is, the FSR 111 is a sensor for measuring pressure, which is not very precise but is designed with a simple structure at a low price, so that unreasonable pressure or weight can be measured. Since the present invention does not provide a fine touch feeling, it can be implemented using the FSR 111 as a sensor.

FIG. 4 is a graph showing the relationship between the position and the touch pressure of the FSR 111 corresponding to the touch input signal in the FSR 111 in the VR cognitive rehabilitation training system for improving the cognitive ability of the elderly with mild cognitive impairment according to the embodiment of the present invention And FIG. Referring to FIG. 4, the controller 130 receives external pressure from the FSR 111 (S11), and determines whether the pressure is less than a preset critical pressure (S12).

If it is determined in step S12 that the pressure is greater than the threshold pressure, the controller 130 performs power OFF control for the LED module 140 (S13).

On the other hand, if it is determined in step S12 that the pressure is smaller than the threshold pressure, the controller 130 performs power ON control for the LED module 140 (S14).

Thereafter, the control unit 130 generates packet data (S15). The packet data generated here includes the magnitude of the force applied by the user to the FSR 111 of the smart block 100, the position of the block measured by the IR sensor 112, And may include position values of objects.

Then, the control unit 130 determines whether the Bluetooth connection is established with the VR interface module 210 of the PC 200 through the control of the Bluetooth module 160 (S16).

If it is determined in step S16 that the Bluetooth connection is not established, the controller 130 determines whether the Bluetooth module 160 is powered on (S17), and then proceeds to step S15 Return.

On the other hand, if it is determined in step S16 that the Bluetooth connection is established, the controller 130 transmits the packet data generated in step S15 to the PC 200 (S18).

The raw codes generated by the FSR 111 are processed by the control unit 130 and the core codes implemented when data is transmitted to the PC 200 are shown in Table 1 below.

4, the sensor value of the FSR 111 is implemented by using data of less than 100, and thus the sensor value of the FSR 111 is calculated in consideration of the fact that the age of the subjects is high, As shown in FIG.

The control unit 130 performs power OFF control for the LED module 140,
A second step of controlling the controller 130 to turn on the LED module 140 when the determination result is smaller than the threshold pressure; And
The controller 130 controls the amount of force applied by the user to the FSR 111 of the smart block 100, the position of the block measured by the IR sensor 112, A third step of generating packet data including a position value of the object around the measured block; Lt; / RTI &gt;
And a fourth step of generating a distance measurement value by measuring a distance to another object located in the vicinity of the smart block 100 from the proximity sensor 113,
In the third step, the controller 130 determines whether a Bluetooth connection with the VR interface module 210 of the PC 200 is established through the control of the Bluetooth module 160 ; &Lt; / RTI &gt;
If it is determined that the Bluetooth connection is not established after step 3-1, the controller 130 determines whether the Bluetooth module 160 is powered on, Step,
If it is determined that the Bluetooth connection is established after step 3-1, the controller 130 controls the size of the generated power by the generated user to the FSR 111 of the smart block 100, 112 for transmitting the packet data of the position of the block measured by the proximity sensor 113 to the VR interface module 210 of the PC 200, 2 &lt; / RTI &gt; step,
After the step 3-2, the VR interface module 210 of the PC 200 receives the smart block 100 from the user and the location sensing information of the smart block 100 in three dimensions The method of claim 1, further comprising the steps of:
