The present invention relates to a massage apparatus including a plurality of vibration devices disposed thereon and configured to generate a stimulus at a point where a vibration device is not disposed, using the plurality of vibration devices.
Recently, apparatuses for maintaining or enhancing the health and physical strength of users or for fatigue recovery and stress reduction in the home, a gym, or the like, for example, a sporting apparatus such as a running machine or a massage apparatus have been developed and has been widely used in real life.
In particular, there has been a high demand for flexing the cramped muscle or overcoming fatigue and stress through massage, and thus a massage apparatus has attracted increasing attention. Massage is one of medical adjuvant therapies of helping blood circulation or fatigue recovery by sweeping, touching, pushing, pulling, tapping, or moving the body using hands or a specific apparatus. An apparatus for performing massage using a mechanical device is a massage apparatus, and a representative example of the massage apparatus is a massage chair for getting massage while a user comfortably sits thereon.
A current massage chair includes a stimulus device such as a roller, a massage stick, or an airbag, and performs massage by applying a stimulus to the human body via an operation of the stimulus device.
However, these stimulus devices are disposed at fixed positions of the massage chair, and thus there is a problem in that a user is not capable of accurately applying a stimulus to a desired part.
In addition, even if it is possible to move the stimulus device, there is a problem in that a limitation in a mechanical design, an increase in costs, or the like is caused in order to move the device itself.
An object of the present invention devised to solve the problem lies in a massage apparatus including a plurality of vibration devices and configured to generate a stimulus at a point in which a vibration device is not disposed using the plurality of vibration devices.
In an aspect of the present invention, a massage apparatus includes a vibration array including a plurality of vibration devices, a driver configured to vibrate the plurality of vibration devices, and a processor configured to control the driver to generate a stimulus at a stimulus point between the plurality of vibration devices by simultaneously vibrating two or more vibration devices among the plurality of vibration devices.
According to the present invention, a stimulus may be generated at a point between vibration devices, and thus a part that is desired to be massaged by a user may be advantageously and accurately stimulated.
According to the present invention, various stimulus points may be formed without movement of a stimulus device, and thus the overcome in terms of mechanical design limitations and an increase in manufacturing costs may be advantageously overcome.
According to the present invention, vibration intensity of a vibration device or a vibrating vibration device may be changed, and thus a point in which a stimulus is generated may be smoothly moved.
According to the present invention, the user may advantageously and accurately stimulate a part that is desired to be massaged by the user by simply touching a screen of the mobile terminal.
According to the present invention, it may be advantageous that the user sets a moving path for smoothly moving a point, in which a stimulus is generated, using touch input through the window of the mobile terminal and that the massage chair smoothly moves the point in which the stimulus is generated according to path setting of the user.
In addition, according to the present invention, the user may also advantageously and simply set moving speed of the stimulus point by adjustment of drag speed.

The plurality of vibration devices 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, and 522 may generate a haptic effect of applying a stimulus to the user, and for example, may generate vibration under control of the processor 210.
In detail, upon receiving current, the plurality of vibration devices 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, and 522 may generate vibration through upward and downward movement, rotation movement, and the like.
The driver 220 may vibrate the plurality of vibration devices.
In detail, the driver 220 may include a plurality of vibration motors that are connected to the plurality of vibration devices 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, and 522, respectively. The driver 220 may include a power transfer circuit configured to supply power to a plurality of vibration motors.
The driver 220 may supply power supplied from a power supply device to a plurality of vibration motors under control of the processor 210.
The processor 210 may generate a control signal for controlling each of the plurality of vibration devices 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, and 522 and may transmit the control signal to the driver 220.
For example, the processor 210 may output a first control signal for control of a first vibration device 511, a second control signal for control of a second vibration device 512, a fourth control signal for control of a fourth vibration device 514, and a fifth control signal for control of a fifth vibration device 515.
Upon receiving the control signal, the driver 220 may separately supply power to a plurality of motors and may separately vibrate the plurality of vibration devices 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, and 522.
The processor 210 may simultaneously vibrate two or more vibration devices among the plurality of vibration devices 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, and 522.
For example, the processor 210 may output the first control signal for vibration of the first vibration device 511 and the second control signal for vibration of the second vibration device 512.
In this case, the driver 220 may supply current to a first vibration motor connected to the first vibration device 511 based on the first control signal to vibrate the first vibration device 511 and may supply current to a second vibration motor connected to the second vibration device 512 based on the second control signal to vibrate the second vibration device 512. Third to twelfth control signals for vibration of third to twelfth vibration devices 513 to 522 are not output, and thus the driver 220 may not supply current to third to twelfth vibration motors that are connected to the third to twelfth vibration devices 513 to 522, respectively. Accordingly, the third to twelfth vibration devices 513 to 522 may not vibrate.
A stimulus point may refer to a point of a user, to which a stimulus is applied.
For example, when the first vibration device 511 vibrates, the stimulus point may be a point {circle around (1)} at which the first vibration device 511 is positioned. In another example, when the second vibration device 512 vibrates, the stimulus point may be a point {circle around (5)} at which the second vibration device 512 is positioned.
The processor 210 may simultaneously vibrate two or more vibration devices among the plurality of vibration devices to generate a stimulus at a stimulus point between the plurality of vibration devices.
Here, the stimulus point between the plurality of vibration devices may be a predetermined point of the vibration array 410 except for points at which the plurality of vibration devices are disposed. The stimulus point between the plurality of vibration devices may be a predetermined point on a line for connecting points on which the outermost vibration devices 511, 512, 513, 516, 519, 522, 521, 520, 517, and 514 are disposed or a predetermined point within a figure generated by connecting the outermost vibration devices 511, 512, 513, 516, 519, 522, 521, 520, 517, and 514.
First, a haptic phenomenon used to generate a stimulus at a stimulus point between a plurality of vibration devices will be described.
A haptic illusion phenomenon may occur in the human. A representative haptic illusion phenomenon may be a phenomenon whereby a soldier who misses a leg in a war feels pain.
Phantom sensation may refer to a phenomenon whereby a stimulus is generated at one point between two points under a specific condition when stimuli are generated at two neighboring points of a skin surface.
Sensory saltation may be an illusion phenomenon of somatic senses and may refer to a phenomenon whereby illusion is caused as if a stimulus continuously moves between stimulus points under a specific condition when a stimulus with repeated and rapid sequences is generated on a skin surface at two or more points.
The processor 210 may generate a stimulus at a stimulus point between the plurality of vibration devices based on at least one of sensory saltation or phantom sensation. In this case, a stimulus point may be formed at a predetermined point between the plurality of vibration devices, but not at points at which the plurality of vibration devices are positioned, and thus the user may feel a stimulus at a point that contacts a predetermined point between the plurality of vibration devices.
First, a method of generating a stimulus at a stimulus point between two vibration devices will be described.
The plurality of vibration devices 511, 512, and 513 that are horizontally arranged will be exemplified.
The processor 210 may control the driver to simultaneously vibrate a first vibration device and a second vibration device, which are adjacent to the stimulus point, and to generate a stimulus at a stimulus point between the first vibration device and the second vibration device.
In detail, the processor 210 may determine a stimulus point. When the stimulus point is positioned between the first vibration device 511 and the second vibration device 512, it may be determined that the first vibration device and second vibration device are adjacent to the stimulus point.
Here, when the stimulus point is positioned between the first vibration device 511 and the second vibration device 512, this means that the stimulus point is positioned on an imaginary line 550 for connecting the first vibration device 511 and the second vibration device 512.
When the first vibration device and the second vibration device are adjacent to the stimulus point, this means that any one of the first vibration device and the second vibration device is most adjacent to the stimulus point and the other one of the first vibration device and the second vibration device is secondly adjacent to the stimulus point among the plurality of vibration devices 511 to 522 or that the first vibration device and the second vibration device are most adjacent to the stimulus point.
When the stimulus point is positioned between the first vibration device 511 and the second vibration device 512, the processor 210 may simultaneously vibrate the first vibration device 511 and the second vibration device 512 which are adjacent to the stimulus point.
In this case, the processor 210 may simultaneously vibrate the first vibration device 511 and the second vibration device 512 under a condition where at least one phenomenon of phantom sensation or sensory saltation occurs.
In this case, the processor 210 may output the first control signal for vibration of the first vibration device 511 and the second control signal for vibration of the second vibration device 512 among the plurality of vibration devices 511 to 522.
Accordingly, a user who sits on the massage chair may recognize a stimulus generated at a stimulus point between the first vibration device 511 and the second vibration device 512.
The processor may determine vibration intensity of vibration devices based on a distance between the stimulus point and vibration devices.
This will be described with reference to
In the graph of
Vibration intensity may be determined based on at least one of a duty cycle of vibration of a vibration device or amplitude of vibration (displacement, e.g., amplitude of upward and downward movement when a vibration device moves in upward and downward directions).
In detail, as a duty cycle of vibration of a vibration device increases, vibration intensity generated by the vibration device may be increased. In addition, as amplitude of vibration of the vibration device (displacement, e.g., amplitude of upward and downward movement when a vibration device moves in upward and downward directions) increases, vibration intensity generated by the vibration device may be increased.
Hereinafter, adjustment of vibration intensity will be described as a method of changing a duty cycle of vibration of a vibration device, but the present invention is not limited thereto and vibration intensity may also be adjusted using a method of changing amplitude of vibration.
A processor may determine vibration intensity of a first vibration device and vibration intensity of a second vibration device based on a first distance between a stimulus point and a first vibration device and a second distance between the stimulus point and a second vibration device.
In detail, a ratio of the second distance to the first distance may be equal to a ratio of the first vibration intensity to the second vibration intensity.
In this regard, first, a case in which a stimulus point is a point {circle around (2)} of
When the stimulus point is the point {circle around (2)}, a vibration device adjacent to the stimulus point among a plurality of vibration devices may be the first vibration device 511 and the second vibration device 512.
The processor may control the driver to generate a stimulus at a stimulus point {circle around (2)} between the first vibration device and the second vibration device by simultaneously vibrating the first vibration device 511 and the second vibration device 512, which are adjacent to the stimulus point.
In this case, the processor may determine first vibration intensity of the first vibration device 511 and second vibration intensity of the second vibration device 512 based on a first distance between the stimulus point {circle around (2)} and the first vibration device 511 and a second distance between the stimulus point {circle around (2)} and the second vibration device 512.
In detail, a ratio of the second distance to the first distance may be equal to a ratio of the first vibration intensity to the second vibration intensity.
For example, it is assumed that the first distance between the stimulus point {circle around (2)} and the first vibration device 511 is 2 cm and that the second distance between the stimulus point {circle around (2)} and the second vibration device 512 is 6 cm. In this case, the second distance may be three times the first distance, and a ratio of the second distance to the first distance may be 3.
In this case, a ratio of the first vibration intensity of the first vibration device 511 to the second vibration intensity of the second vibration device 512 may be 3. That is, the first vibration intensity of the first vibration device 511 may be three times the second vibration intensity of the second vibration device 512.
When the second distance is a specific multiple (e.g., three times) of the first distance, the processor may control the driver to make vibration intensity of the first vibration device 511 be a specific multiple (e.g., three times) of vibration intensity of the second vibration device 512.
For example, as shown in
As different expression, vibration intensity of a vibration device for generating a stimulus at a point at which the vibration device is disposed may be a duty cycle of 100%, and the sum of vibration intensities of vibration devices for generating a stimulus at a stimulus point between a plurality of vibration devices may also be a duty cycle of 100%. In this case, the processor may output the first control signal and the second control signal to make vibration intensity of the first vibration device 511 be a duty cycle of 75% and to make vibration intensity of the second vibration device 512 be a duty cycle of 25%.
Hereinafter, a case in which a stimulus point is a point {circle around (3)} of
When the stimulus point is the point {circle around (3)}, a vibration device adjacent to the stimulus point among a plurality of vibration devices may be the first vibration device 511 and the second vibration device 512.
The processor may control the driver to generate a stimulus at a stimulus point {circle around (3)} between the first vibration device and the second vibration device by simultaneously vibrating the first vibration device and the second vibration device, which are adjacent to the stimulus point.
In this case, the processor may determine vibration intensity of the first vibration device 511 and vibration intensity of the second vibration device 512 based on a first distance between the stimulus point {circle around (3)} and the first vibration device 511 and a second distance between the stimulus point {circle around (3)} and the second vibration device 512.
In detail, a ratio of the second distance to the first distance may be equal to a ratio of the first vibration intensity to the second vibration intensity.
For example, it is assumed that the first distance between the stimulus point {circle around (2)} and the first vibration device 511 is 4 cm and that the distance between the stimulus point {circle around (2)} and the second vibration device 512 is 4 cm. In this case, the first distance and the second distance may be equal to each other, and a ratio of the second distance to the first distance may be 1.
In this case, a ratio of the first vibration intensity of the first vibration device 511 to the second vibration intensity of the second vibration device 512 may be 1. That is, the first vibration intensity of the first vibration device 511 and the second vibration intensity of the second vibration device 512 may be equal to each other.
When the second distance is a specific multiple (e.g., one time) of the first distance, the processor may control the driver to make vibration intensity of the first vibration device 511 be a specific multiple (e.g., one time) of vibration intensity of the second vibration device 512.
For example, as shown in
As different expression, the processor may output the first control signal and the second control signal to make the vibration intensity of the first vibration device 511 be a duty cycle of 50% and to make vibration intensity of the second vibration device 512 be a duty cycle of 50%.
Hereinafter, a case in which a stimulus point is a point {circle around (4)} of
When the stimulus point is the point {circle around (4)}, a vibration device adjacent to the stimulus point among a plurality of vibration devices may be the first vibration device 511 and the second vibration device 512.
In this case, the processor may determine vibration intensity of the first vibration device 511 and vibration intensity of the second vibration device 512 based on a first distance between the stimulus point {circle around (4)} and the first vibration device 511 and a second distance between the stimulus point {circle around (4)} and the second vibration device 512.
In detail, a ratio of the second distance to the first distance may be equal to a ratio of the first vibration intensity to the second vibration intensity.
For example, it is assumed that the first distance between the stimulus point {circle around (4)} and the first vibration device 511 is 6 cm and that the distance between the stimulus point {circle around (2)} and the second vibration device 512 is 2 cm. In this case, the second distance may be ⅓ times the first distance, and a ratio of the second distance to the first distance may be ⅓.
In this case, a ratio of the first vibration intensity of the first vibration device 511 to the second vibration intensity of the second vibration device 512 may be ⅓. That is, the first vibration intensity of the first vibration device 511 may be ⅓ times the second vibration intensity of the second vibration device 512.
When the second distance is a specific multiple (e.g., ⅓ times) of the first distance, the processor may control the driver to make vibration intensity of the first vibration device 511 be a specific multiple (e.g., ⅓ times) of vibration intensity of the second vibration device 512.
For example, as shown in
As different expression, the processor may output the first control signal and the second control signal to make vibration intensity of the first vibration device 511 be a duty cycle of 25% and to make vibration intensity of the second vibration device 512 be a duty cycle of 75%.
When a stimulus point is a point in which a vibration device is positioned like points {circle around (1)} and {circle around (5)} of
For example, when the stimulus point is the point {circle around (1)}, the processor may vibrate the first vibration device 511 positioned at the point {circle around (1)}, as shown in
In another example, when the stimulus point is a point {circle around (5)}, the processor may vibrate the second vibration device 512 positioned at the point {circle around (5)}, as shown in
The processor may change intensity of a vibration device or may change a vibrating vibration device to move the stimulus point.
First, a method of changing intensity of a vibration device to move a stimulus point will be described under the assumption that the stimulus point is moved to the point {circle around (5)} from the point {circle around (1)} of
The point {circle around (1)} may be a point at which the first vibration device 511 is positioned.
In this case, as shown in
Then, the processor may vibrate the first vibration device with the first vibration intensity among the first vibration device and the second vibration device which are adjacent to the stimulus point and may vibrate the second vibration device with smaller second vibration intensity than the first vibration intensity to generate a stimulus at the first stimulus point closer to the first vibration device than the second vibration device.
For example, when the stimulus point is the point {circle around (2)}, the processor may vibrate the first vibration device 511 with vibration intensity of 75% among the first vibration device 511 and the second vibration device 512 which are adjacent to the point {circle around (2)} and may vibrate the second vibration device 512 with vibration intensity of 25%. Accordingly, a stimulus may be generated at the point {circle around (2)} closer to the first vibration device 511 than the second vibration device 512 (refer to
Then, the processor may vibrate the first vibration device and the second vibration device, which are adjacent to the stimulus point, with the same intensity, and may generate a stimulus at an intermediate point between the first vibration device and the second vibration device.
For example, when the stimulus point is the point {circle around (3)}, the processor may vibrate the first vibration device 511 adjacent to the point {circle around (3)} with vibration intensity of 50% and may vibrate the second vibration device 512 adjacent to the point {circle around (3)} with vibration intensity of 50%. Accordingly, a stimulus may be generated at the point {circle around (3)} that is the intermediate point between the second vibration device 512 and the first vibration device 511 (refer to
Then, the processor may vibrate the first vibration device with third vibration intensity among the first vibration device and the second vibration device, which are adjacent to the stimulus point and may vibrate the second vibration device with fourth vibration intensity greater than the third vibration intensity to generate a stimulus at the closer second stimulus point to the second vibration device than the first vibration device.
For example, when the stimulus point is the point {circle around (4)}, the processor may vibrate the first vibration device 511 with vibration intensity of 25% among the first vibration device 511 and the second vibration device 512, which are adjacent to the point {circle around (4)} and may vibrate the second vibration device 512 with vibration intensity of 75%. Accordingly, a stimulus may be generated at the point {circle around (4)} closer to the second vibration device 512 than the first vibration device 511 (refer to
Then, as shown in
The processor may control the first vibration device and the second vibration device to move the stimulus point in this manner.
For example, the processor may output the first control signal and the second control signal and may generate a stimulus at the point {circle around (1)} to make vibration intensity of the first vibration device be 100% and to make vibration intensity of the second vibration device be 0%. Then, the processor may output the first control signal and the second control signal and may generate a stimulus at the point {circle around (2)} to make vibration intensity of first vibration device be 75% and to make vibration intensity of the second vibration device be 25%. Then, the processor may output the first control signal and the second control signal and may generate a stimulus at the point {circle around (3)} to make vibration intensity of the first vibration device be 50% and to make vibration intensity of the second vibration device be 50%. Then, the processor may output the first control signal and the second control signal and may generate a stimulus at the point {circle around (4)} to make vibration intensity of the first vibration device be 25% and to make vibration intensity of the second vibration device be 75%. Then, the processor may output the first control signal and the second control signal and may generate a stimulus at the point {circle around (5)} to make vibration intensity of the first vibration device be 0% and to make vibration intensity of the second vibration device be 100%.
Hereinafter, a method of changing intensity of a vibration device and a vibrating vibration device to move a stimulus point will be described.
The method will be described under the assumption that the stimulus point is moved to the point {circle around (7)} from the point {circle around (4)} of
The processor may simultaneously vibrate the first vibration device and the second vibration device, which are adjacent to the stimulus point, to generate a stimulus at a stimulus point between the first vibration device and the second vibration device.
For example, when the stimulus point is the point {circle around (4)}, a vibration device adjacent to the stimulus point may be the first vibration device 511 and the second vibration device 512.
The first distance between the stimulus point {circle around (4)} and the first vibration device 511 may be 6 cm and the distance between the stimulus point {circle around (2)} and the second vibration device 512 may be 2 cm. In this case, the second distance may be ⅓ times the first distance, and a ratio of the second distance to the first distance may be ⅓.
Accordingly, the processor may control the driver to make vibration intensity of the first vibration device 511 be ⅓ times vibration intensity of the second vibration device 512.
For example, as shown in
That is, the processor may output the first control signal and the second control signal to make vibration intensity of the first vibration device 511 be 25% and to make vibration intensity of the second vibration device 512 be 75%.
The vibration device adjacent to the stimulus point {circle around (2)} may be the first vibration device 511 and the second vibration device 512. Accordingly, the third vibration device 513 and other vibration devices may not vibrate (It may be possible to vibrate the third vibration device 513 or other vibration devices to cause a separate stimulus to a user body. However, vibration of the third vibration device 513 or the other vibration devices are not used to generate a stimulus point using phantom sensation and sensory saltation).
The processor may control the driver to change the stimulus point to point {circle around (5)} from the point {circle around (4)} of
In detail, the point {circle around (5)} may be a point at which the second vibration device 512 is positioned.
In this case, as shown in
The first vibration device 511, the third vibration device 513, and other vibration devices may not vibrate.
The processor may control the driver to change the stimulus point to the point {circle around (6)} from the point {circle around (5)} of
In detail, the processor may simultaneously vibrate the second vibration device and the third vibration device, which are adjacent to a new stimulus point, to generate a stimulus at a stimulus point between the second vibration device and the third vibration device.
For example, when the stimulus point is the point {circle around (6)}, the vibration device adjacent to the stimulus point may be the second vibration device 512 and the third vibration device 513.
A third distance between the stimulus point {circle around (6)} and the second vibration device 512 may be 2 cm and a fourth distance between the stimulus point {circle around (6)} and the third vibration device 513 may be 6 cm. In this case, the fourth distance may be three times the third distance, and a ratio of the fourth distance to the third distance may be 3.
Accordingly, the processor may control the driver to make vibration intensity of the second vibration device 512 be three times vibration intensity of the third vibration device 513.
For example, as shown in
That is, the processor may output the second control signal and the third control signal to make vibration intensity of the second vibration device 512 be 75% and to make vibration intensity of the third vibration device 513 be 25%.
A vibration device adjacent to the stimulus point {circle around (6)} may be the second vibration device 512 and the third vibration device 513. Accordingly, the first vibration device 511 and other vibration devices may not vibrate.
The processor may control the driver to change the stimulus point to the point {circle around (7)} from the point {circle around (6)} of
In detail, the processor may vibrate the second vibration device 512 and the third vibration device 513, which are adjacent to the stimulus point {circle around (7)}, with the same intensity, and may generate a stimulus at an intermediate point between the second vibration device 512 and the third vibration device 513. That is, as shown in
A vibration device adjacent to the stimulus point {circle around (7)} may be the second vibration device 512 and the third vibration device 513. Accordingly, the first vibration device 511 and other vibration devices may not vibrate.
The processor may control the first vibration device, the second vibration device, and the third vibration device to move the stimulus point in this manner.
For example, the processor may output the first control signal, the second control signal, and the third control signal and may generate a stimulus at the point {circle around (4)} to make vibration intensity of the first vibration device be 25%, to make vibration intensity of the second vibration device be 75%, and make vibration intensity of the third vibration device be 0%. Then, the processor may output the first control signal, the second control signal, and the third control signal and may generate a stimulus at the point {circle around (5)} to make vibration intensity of the first vibration device be 0%, to make vibration intensity of the second vibration device be 100%, and to make vibration intensity of the third vibration device be 0%. Then, the processor may output the first control signal, the second control signal, and the third control signal and may generate a stimulus at the point {circle around (6)} to make vibration intensity of the first vibration device be 0%, to make vibration intensity of the second vibration device be 75%, and to make vibration intensity of the third vibration device be 25%. Then, the processor may output the first control signal, the second control signal, and the third control signal and may generate a stimulus at the point {circle around (7)} to make vibration intensity of the first vibration device be 0%, to make vibration intensity of the second vibration device be 50%, and to make vibration intensity of the third vibration device be 50%.
In the above embodiment, a method of applying a stimulus to various stimulus points and a method of moving a stimulus point when vibration devices are horizontally arranged have been described. In addition, such a description may also be applied to the case in which vibration devices are vertically or diagonally arranged, without change.
Hereinafter, a method of applying a stimulus at various stimulus points and a method of moving a stimulus point by a vibration array including a plurality of vibration devices that are vertically and horizontally arranged will be described.
A vibration array 510 may include the plurality of vibration devices 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, and 522 that are vertically and horizontally arranged.
The processor may control the driver to simultaneously vibrate a sixth vibration device 516, an eighth vibration device 518, and a ninth vibration device 519, which are adjacent to a stimulus point, to generate a stimulus at a stimulus point.
In detail, the processor 210 may determine a stimulus point 611. The processor may select four vibration devices 515, 516, 518, and 519 that form a figure for surrounding the stimulus point 611 at the closest distance if being connected to each other, among the plurality of vibration devices 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, and 522. The processor 210 may determine the sixth vibration device 516, the eighth vibration device 518, and the ninth vibration device 519, which are three vibration devices closest to the stimulus point 611 among the four vibration devices 515, 516, 518, and 519, as vibration devices adjacent to the stimulus point.
The processor may simultaneously vibrate the sixth vibration device 516, the eighth vibration device 518, and the ninth vibration device 519, which are three vibration devices close to the stimulus point 611.
In this case, the processor 210 may vibrate three vibration devices close to the stimulus point 611 under a condition in which at least one of phantom sensation or sensory saltation is to be caused.
Accordingly, a stimulus may be generated at a stimulus point between the sixth vibration device 516, the eighth vibration device 518, and the ninth vibration device 519 based on at least one of phantom sensation or sensory saltation, and a user who sits on a massage chair may recognize the stimulus generated at the stimulus point between the sixth vibration device 516, the eighth vibration device 518, and the ninth vibration device 519.
The processor may determine vibration intensity of vibration devices based on distances between a stimulus point and vibration devices.
In detail, the processor may determine first vibration intensity of a sixth vibration device, second vibration intensity of an eighth vibration device, and third vibration intensity of a ninth vibration device based on a ‘first distance ‘c’ between the stimulus point 611 and a sixth vibration device 516’, a ‘second distance ‘a’ between the stimulus point 611 and the eighth vibration device 518, and a ‘third distance ‘b’ between the stimulus point 611 and the ninth vibration device 519’.
In more detail, a ratio of the second distance to the first distance may be equal to a ratio of the first vibration intensity to the second vibration intensity, and a ratio of the third distance to the first distance may be equal to a ratio of the first vibration intensity to the third vibration intensity. A ratio of the first distance to the second distance may be equal to a ratio of the second vibration intensity to the first vibration intensity, and a ratio of the third distance to the second distance may be equal to a ratio of the second vibration intensity to the third vibration intensity.
For example, it may be assumed that the first distance ‘c’ between the stimulus point 611 and the sixth vibration device 516 is 6 cm, the second distance ‘a’ between the stimulus point 611 and the eighth vibration device 518 is 5 cm, and the third distance ‘b’ between the stimulus point 611 and the ninth vibration device 519 is 3 cm.
In this case, a ratio of the second distance ‘a’ to the first distance ‘c’ may be ⅚, and accordingly a ratio of vibration intensity of the sixth vibration device 516 to vibration intensity of an eighth vibration device 518 may be ⅚.
A ratio of the third distance ‘b’ to the first distance ‘c’ may be ½, and accordingly a ratio of vibration intensity of the sixth vibration device 516 to vibration intensity of a ninth vibration device 519 may be ½.
In this case, the processor may control the driver to make vibration intensity of the eighth vibration device 518 be 6/5 times vibration intensity of the sixth vibration device 516 and to make vibration intensity of the ninth vibration device 519 be twice vibration intensity of the sixth vibration device 516.
As different expression, the sum of vibration intensities of vibration devices for generating a stimulus at a stimulus point between a plurality of vibration devices may be 100%. In this case, the processor may output a sixth control signal, an eighth control signal, and a ninth control signal to make vibration intensity of the sixth vibration device 516 be 23.8%, to make vibration intensity of the eighth vibration device 518 be 28.6%, and to make vibration intensity of the ninth vibration device 519 be 47.6%.
The processor may change intensity of a vibration device or a vibrating vibration device to move the stimulus point.
This will be described with reference to

In this case, the processor 210 may determine vibration intensity of the vibration devices based on distances between the stimulus point and the vibration devices.
In detail, the processor may determine sixth vibration intensity of the sixth vibration device, eighth vibration intensity of the eighth vibration device, and ninth vibration intensity of the ninth vibration device based on a ‘first distance ‘i’ between the stimulus point and the sixth vibration device 516’, a ‘second distance ‘j’ between the stimulus point and the eighth vibration device 518’, and a ‘third distance ‘k’ between the stimulus point and the ninth vibration device 519’.
In this case, a ratio of the second distance ‘j’ to the first distance ‘i’ may be equal to a ratio of the sixth vibration intensity to the eighth vibration intensity, and a ratio of the third distance ‘k’ to the first distance ‘i’ may be equal to a ratio of the sixth vibration intensity to the ninth vibration intensity.
The sum of the sixth vibration intensity of the sixth vibration device, the eighth vibration intensity of the eighth vibration device, and the ninth vibration intensity of ninth vibration device may be 100%.
The processor may control the plurality of vibration devices to move the stimulus point in this manner.
For example, as shown in
The stimulus point may be the center point of a figure formed by connecting the fifth vibration device 515, the sixth vibration device 516, the eighth vibration device 518, and the ninth vibration device 519. In this case, the processor may vibrate the fifth vibration device 515, the sixth vibration device 516, the eighth vibration device 518, and the ninth vibration device 519 with the same vibration intensity to generate a stimulus at the stimulus point. In this case, the sum of vibration intensity of the fifth vibration device 515, vibration intensity of the sixth vibration device 516, vibration intensity of the eighth vibration device 518, and vibration intensity of the ninth vibration device 519 may be 100%.
As such, according to the present invention, a stimulus may be generated at a point between vibration devices, and thus a part that is desired to be massaged by a user may be advantageously and accurately stimulated.
According to the present invention, various stimulus points may be formed without movement of a stimulus device, and thus the overcome in terms of mechanical design limitations and an increase in manufacturing costs may be advantageously overcome.
In addition, according to the present invention, vibration intensity of a vibration device or a vibrating vibration device may be changed, and thus a point in which a stimulus is generated may be smoothly moved. For example, vibration intensity may be changed from a first vibration device of 100% and a second vibration device of 0% as a first stage to the first vibration device of 99% and the second vibration device of 1% as a second stage, and in this manner, vibration intensity may be gradually changed up to the first vibration device of 0% and the second vibration device of 100%, and thus the stimulus point may be very smoothly moved from the first vibration device to the second vibration device.

First, operation S1010 of receiving the stimulus pattern from the mobile terminal will be described.
When an application that interworks with a massage chair is executed, a processor of the mobile terminal 100 may display a window 1110 for receiving input of the massage pattern, as shown in
Upon receiving touch input on the window 1110, the processor of the mobile terminal 100 may determine a massage pattern using the touch input received on the window 1110 and may transmit the massage pattern to the massage chair.
In this case, the processor of the massage chair may receive the massage pattern through a communication unit and may generate a stimulus based on the received massage pattern.
The stimulus pattern may include a stimulus point.
In detail, as shown in
In this case, the processor of the massage chair may receive the stimulus pattern and may control a driver to generate a stimulus at a stimulus point 821 corresponding to the point 811 on which the touch input is received.
In detail, upon receiving the stimulus pattern including the information on the point 811 on which the touch input is received, the processor of the massage chair may determine the point 821 corresponding to the point 811 on which the touch input is received, as a stimulus point, and may control the driver to generate a stimulus at the stimulus point 821.
Here, a position of the point 811 on the window 1110, on which the touch input is received, may correspond to a position of the stimulus point 821 on the vibration array 410.
The stimulus pattern may include a moving path of the stimulus point.
In detail, as shown in
In this case, the processor of the massage chair may receive the stimulus pattern and may control the driver to move the stimulus point according to the moving path 911 of the touch input.
In detail, upon receiving the stimulus pattern including the information on the path 911 along which the touch input moves, the processor of the massage chair may move the stimulus point along a moving path 921 corresponding to the path 911 along which the touch input moves. In this case, the processor of the massage chair may control the drier to generate a stimulus while moving the stimulus point along the path 911 along which the touch input moves.
Here, a position of the path 911 along which the touch input moves on the window 1110 may correspond to a position of a moving path of a stimulus point 921 on the vibration array 410.
The stimulus pattern may include a moving path and moving speed of the stimulus point.
In detail, as shown in
In this case, the processor of the massage chair may receive and may move the stimulus point along the moving path corresponding to the path along which the touch input moves at moving speed corresponding to the speed at which the touch input moves.
In detail, the processor of the massage chair may move the stimulus point along the moving path 921 corresponding to the path 911 along which the touch input moves. In this case, the processor of the massage chair may move the stimulus point on the moving path 921 at moving speed corresponding to the speed at which the touch input moves.
According to an embodiment, it is assumed that touch input moves along the path 911 along which the touch input moves for 10 seconds. In this case, the processor of the massage chair may control the driver to move the stimulus point along the moving path 921 of the stimulus point for 50 seconds which is five times 10 seconds. In another example, it is assumed that touch input moves along the path 911 along which the touch input moves, for 5 seconds. In this case, the processor of the massage chair may control the driver to move the stimulus point along the moving path 921 of the stimulus point for 25 seconds which is five times 5 seconds.
In another example, it is assumed that touch input moves along the path 911 along which the touch input moves, for 10 seconds. In this case, the processor of the massage chair may control the driver to move the stimulus point along the moving path 921 of the stimulus point for 10 seconds (i.e., for the same time as a time period where touch input moves). In another example, it is assumed that the touch input moves along the path 911 along which the touch input moves, for 5 seconds. In this case, the processor of the massage chair may control the driver to move the stimulus point along the moving path 921 of the stimulus point for 5 seconds.
In another example, it is assumed that the touch input moves on a first section of the moving path 911 for 3 seconds, moves on a second section of the moving path 911 for 2 seconds, and moves on a third section of the moving path 911 for 4 seconds.
In this case, the processor of the massage chair may control the driver to move the stimulus point on a period corresponding to the first section on the moving path 911 for 3 seconds, to move the stimulus point on a period corresponding to the second section for 2 seconds, and to move the stimulus point on a period corresponding to the third section for 4 seconds.
The processor may receive the stimulus pattern from the mobile terminal in real time and may generate a stimulus according to the stimulus pattern that is received in real time.
Here, real time may refer to a method of immediately performing required calculation and processing at a time point at which data is generated and transmitting the result to a point that requires the same.
In detail, upon receiving touch input, the processor of the mobile terminal may immediately process coordinates data of the touch input to generate a stimulus pattern including at least one of a point on which the touch input is received, a moving path of the touch input, or moving speed of the touch input, and may transmit the generated stimulus pattern to the massage chair.
Upon receiving the stimulus pattern, the processor of the massage chair may immediately process the stimulus pattern to generate a control signal based on the stimulus pattern, and may transmit the generated control signal to the driver.
Although the case in which the processor of the massage chair receives the stimulus pattern to generate a stimulus in real time has been described, the present invention is not limited thereto.
In detail, the massage chair may include a memory, and the memory may store a stimulus pattern that is generated by user input through the mobile terminal or an input unit of the massage chair or is generated by a manufacturer.
The processor of the massage chair may generate a stimulus corresponding to the stimulus pattern using the stimulus pattern stored in the memory.
As such, according to the present invention, a user may advantageously and accurately stimulate a part that is desired to be massaged by the user by simply touching a screen of the mobile terminal.
It may be advantageous that the user sets a moving path for smoothly moving a point, in which a stimulus is generated, using touch input through the window 1110 of the mobile terminal and that the massage chair smoothly moves the point in which the stimulus is generated according to path setting of the user.
According to the present invention, the user may also advantageously and simply set moving speed of the stimulus point by adjustment of drag speed.
