Description

Technical Field

[0001] The invention relates to an intervention system for visual-motor integration of developmental dyslexia and also to a corresponding intervention method, belonging to the technical field of cognitive intervention. Background Art

[0002] Developmental dyslexia is a common neurodevelopmental disorder, accounting for 80% of all specific learning disabilities. Its characteristic is that even if the intelligence is normal and the child receives adequate education and guidance, the patient still shows significant lag in reading ability. This disorder not only causes psychological and behavioral problems for the individual, but also may hinder children from receiving higher education, bringing a heavy burden to society.

[0003] Visual-Motor Integration is the cognitive processing ability to coordinate and integrate visual perception and finger movements, which is closely related to reading and writing ability. For children with dyslexia, visual-motor integration ability plays a key role in identifying and intervening in dyslexia. Studies have shown that through action game training, children's visual-motor ability can be improved, thereby improving their reading ability.

[0004] The Chinese invention patent with patent number ZL 201910811267.1 discloses a training system and method based on the function of the visual magnocellular-dorsal pathway. The training system includes a consistent motion detection module, a visual search module, and a visual tracking module, which aims to train the user's visual magnocellular-dorsal pathway function through these modules, improve their cognitive processing capabilities, and ultimately improve language cognition. The consistent motion detection module is used to train the user's consistent motion and record the training results; the visual search module is used to improve the user's visual search ability; and the visual tracking module is used to train the user's visual tracking ability.

[0005] However, this training system has some limitations. First, it needs to be based on a large corpus and focuses mainly on children's external reading behavior performance, focusing on the training of speech and symbols, which may ignore the multifactorial nature of dyslexia. Secondly, this training system only starts from the perspective of the visual function of the magnocellular pathway and does not fully consider the ability of visual-motor integration, that is, how to combine perceptual ability with actual finger movement ability. Finally, although the training system provides feedback after the training, the real-time feedback during the training process is insufficient, which may affect the timely adjustment and optimization of the training effect.

[0053] The technical content of the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] The embodiment of the present invention aims to provide an intervention system for visual-motor integration ability of developmental dyslexia, which adopts a gamified task form to conduct visual-spatial movement-related training, and includes three training units: (1) dog maze (training attention to peripheral stimuli); (2) fingertip line drawing (training high sensory load to serve accurate motor planning); and (3) box closing (training response to the unpredictability of time and space).

[0055] The dog maze unit is used to train the user's motion perception ability and train the user's attention and perception of peripheral stimuli. Motion perception ability is: visual inference of motion based on the speed and direction of elements in the environment. The dog maze unit is characterized by attention to peripheral stimuli.

[0056] The fingertip line drawing unit is used to train the user's motor control ability. Motor control ability is the ability to regulate or manage movements. Motor defects caused by decreased motor control ability are high risk factors for dyslexia. The fingertip line drawing unit is characterized by a high level of sensory motor load and motor control.

[0057] The box-closing unit is used to train the user's visual tracking ability. Visual tracking ability is the ability to follow and track objects with coordinated eye movements. The characteristics of the box-closing unit are that objects appear instantly and move at uneven speeds, which is unpredictable.

[0058] It can be understood that the visual-motor integration ability training in the embodiment of the present invention can not only train the dorsal magnocellular pathway, but also practice the fine motor skills of the fingers during the training process, thereby improving children's control ability during the writing process.

[0059] First embodiment

[0060] like Figures 1 to 4 As shown, a visual-motor integration intervention system for developmental dyslexia provided by the first embodiment of the present invention includes a motion perception unit 1, a motion control unit 2, and a visual tracking unit 3. The motion perception unit 1 is used to present a motion scene to the user, so as to visually infer the motion based on the speed and direction of the element image in the motion scene, thereby training the user's motion perception ability. The motion control unit 2 is used to present a painting scene to the user, so as to require the user to complete the drawing of the corresponding shape within a preset time based on the shape to be drawn in the painting scene, and ensure that the similarity meets the preset threshold, thereby training the user's motion control ability. The visual tracking unit 3 is used to present a screen click scene to the user, so as to randomly appear the elements to be clicked at multiple preset positions based on the screen click scene, and require the user to complete the click action within a preset time, thereby training the user's visual tracking ability.

[0061] Below, each unit of the intervention system is described in detail:

[0062] (1) Motion perception unit (dog maze unit)

[0063] In this embodiment, the motion perception unit 1 includes a first rule library 11, a first element library 12, a path detection module 13 and a wall detection module 14. Specifically, the first rule library 11 includes a plurality of road rules of different difficulty levels. Each road rule includes at least road width, road length, road type, whether there is an obstruction in the road, whether there is a fork in the road and the total length of the road. The first element library 12 includes at least a background image, multiple roads, a control joystick, and element images in different states. The path detection module 13 is used to detect the movement path of the element image in the road, and output the movement result according to the detection result, and the movement result includes at least whether it is successfully walked out and the movement duration. The wall detection module 14 is connected to the path detection module 13 to detect whether the element image touches the edge of the road in the road based on the movement path.

[0064] Reference Figure 2As shown, in this embodiment, the sports scene is configured as follows: a corresponding road (a maze in this embodiment) is formed based on a road rule and presented on a background image, and an element image (a puppy in this embodiment) is set at the starting point of the road, so that the element image can be controlled to move within the road by controlling the joystick, thereby moving the puppy icon to complete the maze task.

[0065] Specifically, when the puppy icon appears, the user needs to move the puppy to walk through the maze along the specified route within t1. Press anywhere on the screen to display the center of the joystick, and slide your finger to move the joystick to control the puppy's movement route. The joystick dot slides with your finger, but the center of the circle will not exceed the outer circle. During the movement, it is necessary to prevent the puppy from touching the edge of the maze. If it touches, the center of the joystick is restored, and then the joystick is hidden. It can be restored after t2.

[0066] The core parameter involved in the motion perception unit 1 is the road question bank, which is divided into different questions according to different difficulties. The main design parameters are (1) road width; (2) road length; (3) road type (straight line, oblique line, broken line); (4) whether there are obstacles in the road; (5) whether there are forks in the road; and (6) the total length of the road.

[0067] The following are the specific steps of the dog maze task:

[0068] In the first step, the user clicks OK to start the formal training task.

[0069] The formal training task configuration is retrieved from the road question bank: roads of different difficulty levels.

[0070] Retrieve from the element library: (1) background image; (2) road; (3) joystick; (4) images of dogs in different states.

[0071] For example: the user clicks OK to start training. After the training task starts, the instructions are displayed first: Please help the puppy find food within x seconds (the prompt content is displayed in a smaller font below: Do not touch the wall. Each time you touch the wall, the puppy will cry for 1 second before you can move forward). The map path of the question is refreshed, and then the background is randomly generated in the blank space, and the question countdown and operation prompts are displayed. The prompt content is: Press and hold anywhere on the screen to use the joystick to move the puppy. The game interface is officially entered, and the starting point puppy and the end point food are refreshed.

[0072] In the second step, the user uses the joystick to move the puppy through the path to eat the food. The virtual joystick is not displayed by default. When the finger presses the screen, the joystick is displayed at the pressed position. When the finger slides, the center dot of the joystick slides with the finger, but the center of the circle will not exceed the outer circle. When the finger is released, the center of the joystick is restored and then the joystick is hidden.

[0073] (2) Motion control unit (fingertip drawing unit)

[0074] In this embodiment, the motion control unit 2 includes a second rule library 21, a second element library 22 and a line detection module 23. Specifically, the second rule library 21 includes a similarity target, a shape to be drawn, a disappearance duration and a disappearance interval. The second element library 22 includes a brush, multiple shapes and a canvas. The line detection module 23 is used to detect the line traces of the brush on the canvas and output a drawing result according to the detection result; the drawing result at least includes the final drawing shape and similarity.

[0075] like Figure 3 As shown, in this embodiment, the painting scene is configured as follows: lines are drawn on the canvas by a brush according to the shape to be drawn; and the shape to be drawn suddenly disappears and appears according to the disappearance interval and disappearance duration.

[0076] Specifically, when a shape to be drawn appears, the user needs to drag the brush with his hand to complete the shape within t time while ensuring similarity. When a line shape to be drawn appears, the user starts to press and hold the part to be drawn to enter the drawing state, and drag the brush on the screen with his finger to draw the line. If you release your finger, the brush will change to a hovering state. During the drawing process, the shape to be drawn may suddenly disappear and appear.

[0077] The core parameters involved in the motion control unit 2 include:

[0078] (1) Similarity target: the difference ratio between the user's drawing and the target drawing. For example, 60% means that the overlap reaches 60% or above.

[0079] (2) Shape: The style of the target figure. There are n styles in total, depending on the difficulty.

[0080] (3) Disappearance duration: the time it takes for the target graphic to disappear;

[0081] (4) Disappearance interval: the time interval during which the target graphic disappears.

[0082] The following are the specific steps of the fingertip line drawing task:

[0083] In the first step, the user clicks OK to start the formal training task.

[0084] The formal training task configuration is retrieved from the formal task rule library: (1) similarity target; (2) shape; (3) disappearance duration; (4) disappearance interval.

[0085] Retrieve from the element library: (1) pen; (2) line to be drawn; (3) canvas.

[0086] For example, the user clicks OK to start the training. After the training task starts, the instruction is displayed first: Draw lines on the picture book, and try to be consistent with the lines in the picture book; then the game interface is officially entered, the line shape and brush to be drawn are refreshed at the top, and the question requirement text is displayed at the bottom: The similarity reaches x%.

[0087] In the second step, the user draws a line. The initial state of the brush on the screen is the hovering state. When the required line shape appears, the user can start to press and hold the part to be drawn to enter the drawing state. The brush on the screen can follow the finger to drag the line. Release the finger and it will return to the hovering state again. Each time the state changes, the position of the brush remains unchanged, and you can continue to draw.

[0088] (3) Visual tracking unit (box closing unit)

[0089] In this embodiment, the visual tracking unit 3 includes a third rule library 31, a third element library 32 and a click detection module 33. The third rule library 31 includes element appearance interval, unboxing time and reminder pause time. The third element library 32 includes background decoration, multiple boxes and elements to be clicked. The click detection module 33 is used to detect the click position and output the click result based on the detection result; the click result at least includes whether the click is completed and whether the click is correct.

[0090] like Figure 4 As shown, in this embodiment, the screen click scene is configured as follows: an element to be clicked appears randomly from multiple boxes, and the box is slowly opened until the box is fully opened, pauses for a reminder time, and closes the box, and then an element to be clicked appears randomly again.

[0091] Specifically, there is a kitten in each of the five boxes in a row. In one round of the game, a kitten will randomly come out of a box, slowly open the box, and make a sound when the box is opened to a certain extent. The user needs to click the corresponding box in time before the kitten makes a sound.

[0092] The core parameters involved in the visual tracking unit 3 include:

[0093] (1) Kitten appearance interval: the interval between the appearance of one cat and the appearance of the next cat;

[0094] (2) Box opening time: the time it takes for a cat to appear and then open the box;

[0095] (3) Reminder pause time: The time the kitten stays in the box after it is opened. When the time is up, the kitten retreats back into the box and closes it.

[0096] The following are the specific steps for closing the box task:

[0097] In the first step, the user clicks OK to start the formal training task.

[0098] The formal training task configuration is retrieved from the formal task rule library: (1) the interval between kitten appearances; (2) the box opening time; and (3) the reminder pause time.

[0099] Retrieve from the element library: (1) Background decoration; (2) 5 boxes; (3) Cat.

[0100] For example, the user clicks OK to start the training. After the training task starts, the instructions are displayed first: when the kitten pops out of the cardboard box, click the cardboard box to stop the kitten; then the game interface is officially entered, and a row of 5 cardboard boxes are displayed in the middle, with a kitten in each box.

[0101] In the second step, the user needs to close the box in time. The kitten will slowly open the box. When it is opened to a certain extent, the kitten will make a sound and pause for a while. Then the kitten will quickly open the box and get out. The user needs to click on the box to close it before the kitten gets out. If it is closed in time, it will prompt that the answer is correct; if it is not closed in time, it will prompt that the answer is wrong.

[0102] In the above embodiment, preferably, the intervention system also includes a difficulty adjustment unit 4. The difficulty adjustment unit 4 is connected to the motion perception unit 1, the motion control unit 2 and the visual tracking unit 3 respectively, so as to dynamically adjust the difficulty according to a increase and b decrease. That is, the difficulty of question a increases when the answer is correct, and the difficulty of question b decreases when the answer is wrong. The initial difficulty of the first training is 1, and the difficulty is inherited in subsequent training. Wherein, a and b are both positive integers, and the numerical values ​​can be set as needed, for example: a=2, b=1.

[0103] Second embodiment

[0104] like Figure 5 As shown, based on the above first embodiment, the second embodiment of the present invention further provides an intervention method for visual-motor integration of developmental dyslexia, which specifically includes steps S1 to S3:

[0105] S1: Training of motion perception ability.

[0106] Specifically, a motion scene is presented to the user through the motion perception unit 1 to obtain the user's visual inference result of the motion based on the speed and direction of the element image in the motion scene, so as to train the user's motion perception ability. The specific training process refers to the task steps of the motion perception unit 1 in the first embodiment, which will not be repeated here.

[0107] S2: Training of motor control ability.

[0108] Specifically, a painting scene is presented to the user through the motion control unit 2 to obtain the shape drawn by the user within a preset time based on the shape to be drawn in the painting scene, so as to train the user's motion control ability. The specific training process refers to the task steps of the motion control unit 2 in the first embodiment, which will not be repeated here.

[0109] S3: Training of visual tracking ability.

[0110] Specifically, a screen click scenario is presented to the user through the visual tracking unit 3 to obtain the screen click result of the user within a preset time based on the screen click scenario, so as to train the user's visual tracking ability. The specific training process refers to the task steps of the visual tracking unit 3 in the first embodiment, which will not be repeated here.

[0111] In addition, in this embodiment, preferably, it also includes:

[0112] S4: Adaptive difficulty adjustment.

[0113] Specifically, during the training process, the difficulty is dynamically adjusted according to a increase and b decrease based on the difficulty adjustment unit 4. Wherein, a increase and b decrease means that the difficulty increases if a questions are answered correctly in succession, and the difficulty decreases if b questions are answered incorrectly.

[0114] It is understandable that there is no order in which the above steps S1 to S3 are performed, but the training capabilities are different. Moreover, each step includes step S4 to achieve dynamic adjustment of the task difficulty during the training process.

[0115] In summary, the intervention system and method for visual-motor integration of developmental dyslexia provided by the embodiments of the present invention have the following beneficial effects:

[0116] (1) The present invention is independent of the user's reading ability and knowledge reserve, and adopts action game-style interactive tasks to intervene in the user from a more basic level of perception and visual magnocellular pathway.

[0117] (2) Adopting an adaptive difficulty algorithm, including multiple adjustable parameters, the training process is dynamically adjusted according to the user's ability level. Practicing in the user's zone of proximal development can provide the most suitable training rhythm for the user and enhance the training effect.

[0118] (3) The three functional units of the present invention are designed in accordance with the intervention schemes in existing empirical studies, namely: a. attention to peripheral stimuli; b. high sensory load and motor anticipation; c. unpredictability in time and space.

[0119] (4) The intervention tasks are lively and interesting, with cartoon characters that attract children. The tasks are professionally designed as games, which provide a better user experience. While ensuring the training effect of children, the fun factor is increased, which in turn improves children's compliance and is conducive to the development of long-term training.

[0120] (5) It can effectively exercise the user's fine motor skills during the training process, integrate visual perception and movement, and promote the improvement of writing skills.

[0121] It should be noted that the above embodiments are only examples, and the technical solutions of the various embodiments can be combined, all within the protection scope of the present invention.

[0122] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.
