Referring to
First, the pegboard training device is configured to provide the user with training including inserting pegs onto a board including a plurality of holes.
In the step of receiving the game execution request from the user by the pegboard training device (S100), the game is executed by inserting a peg into a hole presented by the pegboard training device on the pegboard or inserting pegs while forming a route according to a guide provided by the pegboard training device.
That is, in an embodiment of the present disclosure, the game is a game of inserting a peg into a hole as requested by the pegboard training device, and in another embodiment, the game is a game of inducing the user to insert pegs while forming a route as determined by the user among various possible routes using a plurality of points provided by the pegboard training device.
Specifically, the game according to an embodiment of the present disclosure includes inserting a peg into at least one hole presented by the pegboard training device on the pegboard, i.e., inserting pegs into a predetermined number of holes after the pegboard training device presents the predetermined number of holes.
Further, the game according to another embodiment of the present disclosure includes forming a route by inserting pegs by the user into holes, which have not been presented by the pegboard training device, on the pegboard at the user's discretion, i.e., inserting pegs by the user into holes, which have not been presented by the pegboard training device, at the user's discretion after the pegboard training device presents a plurality of holes.
Furthermore, the game according to yet another embodiment of the present disclosure includes removing a peg inserted in a hole by the user after the pegboard training device guides the user to remove the peg, i.e., removing a peg already inserted in a hole on the pegboard by the user after the pegboard training device guides the user to remove the peg.
According to still another embodiment, the pegboard training device presents a moving point that forms a route, and the game is over when the user inserts a peg on the route of the movable point as expected by the user and the inserted peg meets the moving point.
The level of difficulty can be set depending on the type of each game, and the training mode may be provided differently depending on input information of the user or the user's condition.
The step of providing the user with the game (S120) includes various methods for providing the game according to the above-described embodiments.
One of various purposes of the present disclosure is to provide rehabilitation training for stroke patients. A neglect patient among brain-damaged stroke patients does not show defects in a visual field test but neglects and cannot recognize visual, auditory and tactile stimuli on his/her affected side.
Such a neglect patient needs to continuously perform stimulation training to the side of neglecting stimuli.
Therefore, if the user who executes the game is a patient with a defect on one side of the visual field or a neglect patient among brain-damaged stroke patients, the user is requested to insert a plurality of pegs into a plurality of holes at specific positions in the pegboard training device in a direction of from left to right or from right to left in the step of providing the user with the game (S120).
Here, the direction of from left to right or from right to left may be set in consideration of one side of the patient with a defect on one side of the visual field and a neglected side of the neglect patient.
In an embodiment, the specific positions where the insertion is requested are positions where the patient is guided to insert pegs sequentially from a visible or recognizable point in the visual field of the patient to an invisible or unrecognizable point in the opposite direction to the visible point.
For example, a neglect patient who neglects the right side is requested to insert pegs sequentially from a point on the left to a unrecognizable point on the right.
In another embodiment, the specific positions where the insertion is requested include a plurality of specific positions, and the pegboard training device presents all of the plurality of specific positions and requests the user to insert pegs sequentially from one of the plurality of specific positions that is in an invisible region in the visual field of the user and is the farthest from a visible region in the visual field of the user toward the visible region in the visual field of the user.
If a position where the user has inserted a peg is closer to the visible region in the visual field of the user than to a position where the insertion of a peg has been requested, the user is guided that he/she needs to further insert a peg at a position in the invisible region.
By guiding the user that he/she needs to further insert a peg at a position in the invisible region so as to continuously perform the training, it is possible to provide a rehabilitation training effect for a patient with a visual field defect or a neglect patient to recognize an invisible or unrecognizable region.
If the specific positions are arranged in the same column, it is impossible to set the left or right direction. Therefore, the specific positions are arranged in a diagonal or horizontal direction, but are not arranged in the same column on a plurality of holes based on the user.
If the user who executes the game is a patient with a defect on one side of the visual field or a neglect patient among brain-damaged stroke patients, a game execution method will be described later in detail with reference to
In the step of providing the user with the game (S120) according to another embodiment, the pegboard training device presents a plurality of points to the user and requests the user to insert pegs into a plurality of holes on a route connecting the plurality of points.
There may be various routes connecting the plurality of points, but in the cognitive training, whether or not the user can connect the plurality of points in the shortest distance is checked and the user can be trained to connect the plurality of points in the shortest distance.
If the user is provided with the game of inserting pegs into a plurality of holes on a route connecting a plurality of points (hereinafter, referred to as “shortest distance connection game”), an evaluation is made based on at least one of the presence or absence of the shortest distance route, the number of pegs inserted, the level of difficulty and the game execution time and the user is guided to the result of evaluation in the step of guiding the user to the evaluation of the game result (S160).
The result of evaluation may be stored for each user in the pegboard training device, and if the game is performed several times, the results of evaluation may be compared and provided.
Further, the result of evaluation may not only present the result of game execution but may also be provided to help the medical staff in determining the rehabilitation progress of the user based on the result of evaluation.
The step of guiding the user to the evaluation of the game result (S160) may include guiding the user to the result of evaluation and also include, in the game of inserting pegs into a plurality of holes on a route connecting a plurality of points, guiding the user that there is, if any, a unnecessary route other than a route connecting the plurality of points formed by pegs inserted by the user and requesting the user to correct the route.
If the user corrects the route in response to the request from the pegboard training device, the pegboard training device may again provide the user with the result of evaluation. The recognition of which route is wrong and the removal of pegs can also be applied as the result of cognitive training.
An execution method of the shortest distance connection game will be described in detail later with reference to
In the step of providing the user with the game (S120) according to another embodiment, the pegboard training device presents a first point that is moving and a second point that is fixed, and when the first point moves to reach the second position, the game is over. The game according to the present embodiment will be hereinafter referred to as “destination reaching game”.
The first point moves according to a predetermined rule, and if a movement route of the first point is blocked, the first point is rerouted to a predetermined direction and continues to move.
When the movement route of the first point is blocked, the first point may reach the end of the pegboard device or a point where a peg has been inserted.
Therefore, the user needs to reroute the direction of the first point so that the first point moves to reach the second point. When a peg is inserted into a hole, the direction is rerouted. Accordingly, a peg needs to be inserted at a position where the direction needs to be rerouted.
When a peg is inserted at the most suitable position, the first point can most quickly reach the second point. Therefore, a short time is required, the least number of pegs may be used and the first point moves along the least number of holes.
Accordingly, as for the destination reaching game, in the step of providing the user with the game (S120), an evaluation is made based on at least one of the game execution time, the success or failure in the game, the number of pegs used and the number of holes along which the first point moves and the user is guided to the result of evaluation.
Like the result of evaluation of the shortest distance connection game, the result of evaluation of the destination reaching game may be stored for each user in the pegboard training device, and if the game is performed several times, the results of evaluation may be compared and provided.
Further, the result of evaluation may not only present the result of game execution but may also be provided to help the medical staff in determining the rehabilitation progress of the user based on the result of evaluation.
In the step of providing the user with the game (S120) according to another embodiment, the pegboard training device provides a specific shape and requests the user to insert pegs along the specific shape.
The specific shape includes a predetermined shape in the pegboard training device and also includes the shape of a pattern formed directly by the user.
The predetermined shape may include one shape selected by the user from among predetermined shapes in the pegboard device.
The pattern set directly by the user is formed by receiving the selection of a plurality of holes from the user.
That is, the user directly selects each of a plurality of holes into which respective pegs will be inserted to form the pattern set directly by the user.
For example, the predetermined shape may include a linear shape, a cross shape, a circular shape, a square shape, a diamond shape, a triangular shape, a star shape, a heart shape and the like, but is not limited thereto and may include all shapes using a plurality of holes.
In the step of providing the user with the game (S120) according to another embodiment, the pegboard training device provides the user with a game of selecting and inserting pegs.
If the pegs include magnets having different intensities, the pegs are color-coded for each magnetic intensity. The pegboard training device presents the color of a peg to be inserted into a presented hole.
If the user inserts a peg according to the presentation of the pegboard training device, the pegboard training device can evaluate whether the peg of the color to be inserted has been inserted correctly based on the magnetic intensity recognized by a hole in which the peg has been inserted.
If the pegs include bipolar magnets, both ends of the pegs are differentiated by polarity. The pegboard training device requests the user to turn over and insert a peg having different polarities on either end.
If the user inserts a peg according to the request from the pegboard training device, the pegboard training device can recognize the polarity of the peg inserted in a hole and evaluate whether the peg has been turned over and inserted according to the request.
In the above-described embodiments, the step of providing the user with the game (S120) further includes providing a peg insertion point in order for the user to insert a peg at a distance sufficient for a range of motion (ROM) of the user to be extended in consideration of the ROM of the user.
In the present disclosure, the distance sufficient for the ROM to be extended refers to a distance limited within a normal ROM.
That is, the step of providing a peg insertion point in order for the user to insert a peg at a distance sufficient for the ROM to be extended is included in rehabilitation training of the user whose ROM cannot reach the normal ROM to extend the ROM to the normal ROM.
In the step of providing a peg insertion point in order for the user to insert a peg at a distance sufficient for the ROM to be extended according to the above-described embodiments, when a point for guiding the user to insert a peg is presented to the user whose ROM cannot reach the normal ROM, the peg insertion guiding point is placed gradually farther than the ROM.
In this case, desirably, the peg insertion guiding point placed gradually farther than the ROM is a middle point or an end point rather than a start point.
If the start point is placed farther than the ROM, the user may not even start the game. Therefore, the start point is placed within the ROM and the middle point or the end point is placed farther than the ROM. Thus, the ROM can be gradually extended as the user inserts pegs.
In the step of guiding the user to the evaluation of the game result (S160), when the user forms a route by inserting pegs, the result of evaluation is produced in consideration of a case where a peg is inserted farther than the ROM of the user, and the user is guided to the produced result of evaluation.
The pegboard training method according to an embodiment of the present disclosure further includes a step of providing a guide by the pegboard training device after recognizing whether a hand gripping a peg has been supposed to grip the peg.
Whether a hand gripping a peg has been supposed to grip the peg can be recognized based on mutual recognition between a finger wearable device worn on the user's finger and the peg.
The mutual recognition between the finger wearable device worn on the user's finger and the peg may use at least one of near field communication (NFC) or radio frequency identification (RFID), or may include mutual recognition between the finger wearable device including a magnet and a plurality of pegs each including a magnetic sensor.
In a case where at least one of near field communication (NFC) or radio frequency identification (RFID) is used, when a peg is inserted into a hole, the pegboard training device determines whether a touch between the finger wearable device and the peg has been recognized and deduces a result on whether the peg has been inserted by a hand wearing the finger wearable device and then provides the result to the user.
In a case where mutual recognition between the finger wearable device including a magnet and a plurality of pegs each including a magnetic sensor is used, when a peg is inserted into a hole, the pegboard training device deduces a result on whether the peg has been inserted by a hand wearing the finger wearable device depending on whether the magnetism has been sensed by the magnetic sensor of the peg and then provides the result to the user.
The mutual recognition between the plurality of pegs and the finger wearable device makes it possible to know which hand was used to insert a peg. Therefore, if a hand in need of training is not used, the pegboard training device can present the user to insert a peg with the hand in need of training.
The finger wearable device may include all devices, such as a glove or a ring, which can be worn on the finger.
The pegboard training method according to an embodiment of the present disclosure further includes a step of initial setting in a customized manner by the pegboard training device before the step of providing the user with the game (S120).
The step of initial setting is performed by calculating at least one of an approach range or an approach direction of the user's finger to a plurality of holes on the board.
That is, the user is requested to touch a hole on the board with his/her finger to diagnose the user's condition, and initial setting is performed according to the user's condition.
The initial setting is performed for patients with learned non-use who do not often use their affected arms. The current range or form of motion of a hand in need of rehabilitation is diagnosed to present a game suitable for training a part of learned non-use to insert a peg.
In the initial setting, the direction or distance between points presented in each of the above-described games can be customized for the user and the ROM can be diagnosed in advance. Therefore, it is possible to provide a game for gradually extending the ROM. In an embodiment, if the pegboard training device is configured including a main device and a replaceable board including a plurality of holes, a board used for calculating an approach range or an approach direction of the user's finger to a plurality of holes on the board in the initial setting may be smaller in thickness than a board used for executing a game.
To calculate the approach range or the approach direction of the user's finger to a plurality of holes on the board, a magnet may be attached to the user's finger or may be placed on the user's finger by wearing a glove. Then, when the user's finger with the magnet is located near a hole sensor, it can be recognized and a result value can be extracted.
Therefore, to sense the magnetism between the user's finger and the hole sensor, the board needs to be smaller in thickness than the board used for inserting pegs. If so, sensing can be accurate, and, thus, an accurate result value can be extracted.
The pegboard training method according to an embodiment of the present disclosure may further include a step of presenting, on an external display, the proceedings of the game performed on the board.
The external display may present the proceedings of the game performed on the board identically as shown on the board or may present a guide to execute a game, an operation for initial setting, a screen with various options and the like.
The external display may be combined as one body with the pegboard training device and thus cannot be separated from each other, or may be provided separately from the pegboard training device and thus can be separated from each other.
Further, the pegboard training device that provides the pegboard training method according to an embodiment of the present disclosure includes a bidirectional manipulation unit and a display unit and provides at least one of operations for pegboard training, a guide to a game, and an evaluation of a game result on the display unit.
The bidirectional manipulation unit may be provided separately from the display unit, or the display unit may also serve as the manipulation unit by touching the display unit.
The display unit includes a screen whose direction can be switched to two directions, and, thus, the direction of the screen can be switched to a direction of manipulation of the user as manipulated by the user. The direction of manipulation of the user is recognized according to a direction to which the user uses the bidirectional manipulation unit.
The presentation direction of the display unit can be switched according to the direction of manipulation of the user so that the user can use the pegboard training device without changing the direction of the pegboard training device at a position where the user uses the pegboard training device.
Further, two users can execute the game facing each other. A patient on one side and a rehabilitation trainer or caretaker on the other side may be located and the rehabilitation trainer or caretaker may select a game suitable for the patient and perform initial setting so that a game suitable for the patient's condition can be provided.
Hereinafter, various embodiments of a method for providing the above-described game to the user will be described with reference to the accompanying drawings.
The examples illustrated in
The user is guided to insert pegs sequentially from a rightmost hole 201 that is a visible or recognizable point in the visual field of the user to a leftmost hole 204 that is an invisible or unrecognizable point.
The pegboard training device presents all the plurality of specific positions to the user and requests the user to insert pegs sequentially from one of the plurality of specific positions that is on an invisible or unrecognizable region in the visual field of the user and is the farthest from a visible or recognizable region in the visual field of the user toward the visible region in the visual field of the user.
In
If the user inserts pegs into middle holes 301, 302, 306 and 307 in the visible region or the invisible region, the pegboard training device guides the user that he/she needs to insert a peg into a hole in the more left region.
Referring to
If the plurality of points 411, 412 and 413 that needs to be connected to each other is presented as shown in
In this case, a peg inserted in a hole 404 is inserted on a route irrelevant to a route connecting the plurality of points 411, 412 and 413, and, thus, the pegboard training device may request the user to correct the route.
When the user removes the peg inserted in the hole 404 in response to the request from the pegboard training device to correct the route, the execution of the game is completed.
Referring to
The destination reaching game is over when the first point that is moving moves to reach the second position that is fixed.
The first point moves according to a predetermined rule, and if a movement route of the first point is blocked, the first point is rerouted to a predetermined direction and continues to move.
When the movement route of the first point is blocked, the first point may reach the end of the pegboard device or a point where a peg has been inserted.
Referring to
The first point that has been rerouted to the right direction moves again sequentially one by one to holes 516, 517, 518, 519 and 520, and since there is no more hole in the right direction at the end of the pegboard device, the movement route is blocked.
In this case, the first point is rerouted again to the right direction and continues to move sequentially one by one to holes 512, 522 and 523.
When the user uses a peg to reroute the movement direction of the first point and the first point reaches the second point 530 that is fixed, the execution of the game is completed.
