Description

Interaction device for improving time cognition of children and control method thereof

Technical Field

The invention relates to the technical field of children home products, in particular to a control method of an interaction device for improving time cognition of children.

Background

Children before seven and eight years old often judge time intervals by taking spatial characteristics as references, the time and the distance are mixed up, and the age is more obvious. That is, children before the age of seven or eight often judge new time intervals by taking spatial characteristics as references, and confuse time with the sizes of enlarged areas and volumes.

From a psychological point of view, the poor management time of children is mainly due to the following factors:

(1) the particularity of time is an objective factor of the difficulty of time management for children, time is not intuitive, and it can be perceived only indirectly through actions or certain activities, through the replacement of certain frequent phenomena, and through specialized instruments (such as clocks).

(2) The development of time perception of children is an age factor influencing the time management of children, and the premise of effective time management is accurate and stable time perception.

(3) The time management tendency of children is a personality factor influencing the time management of children. Time perception is the basis for effectively managing time, and a certain time management tendency is the key for effective management.

To clarify the actual condition, an online questionnaire was performed to collect 88 parts in total. On the grade, the kindergarten is more in large class and middle class, and the proportion is 76 percent. In the aspect of cognitive situation of time, most children have time concepts, more than half of the children have certain time concepts but do things and drag without paying attention to the time, and the children not knowing the time concepts only account for 18.6%; in the aspect of self-holding control over time, 65.12 percent of children have certain time awareness, but sometimes have a delay phenomenon, self-reversing or improvement under the teaching of others; in the scheduling of children, nearly half of the parents consider the children to require minor improvement (individual activities are time-delayed, affecting other tasks), and 34.88% of the parents consider the children to require rearrangement (e.g., more greedy to play, excessive time spent playing, etc.). The children have strong plasticity and great demand for time cognition and control in the 5-7 year old stage.

Children are the key stage of time concept cultivation in the age of 5-7 years, and the time concept cultivation is influenced by good training of guidance and learning. The time cognition of children is not clear enough, the time duration can not be accurately sensed, and the phenomenon of delay is caused.

Disclosure of Invention

The invention aims to provide an interaction device for improving time cognition of children and a control method thereof, and aims to improve the time cognition of the children in an interesting interaction mode, help the children to reduce delayed behaviors and enable the children to establish a good time concept in the young.

In order to solve the technical problems, the invention provides the following technical scheme:

the specific technical scheme is as follows:

the interaction device for improving the time cognition of the children comprises a voice recognition module, a key, a loudspeaker, a lithium battery, an LED lamp, a motor and a chip thereof; the button, the LED lamp, the motor and the chip form a control group, the control group comprises a plurality of groups of control groups, and each group of control groups has the function.

The control method of the interaction device for improving the time cognition of the children comprises the following steps:

the first is time validation; the main control chip controls the display screen to randomly display a time, and the voice recognition module is in a receiving state at the moment; when the sound of the child is detected and compared in the main control chip, the main control chip controls the device to make a corresponding response according to the result;

the second is a story and interaction between seconds/min/hour; the main control chip controls the motor to enable the gravity center of an object connected with the motor to shift, and the corresponding animation image on the display screen is shaken after the left and right shifts; reading audio data in the SD card during shaking, telling a small story between seconds/minutes/hour to a child, raising small questions behind the story to allow the child to select, and selecting correct options by voice; the voice recognition module receives the voice and compares the voice with the result in the main control chip;

the third is a daily countdown; the base is provided with an aperture, timing is carried out in the main control chip, and a lamp is turned off after fixed time, so that the quantity of light emitted gradually decreases along with the lapse of time; when all the LED lamps are turned off, all the LED lamps are turned back to be on.

Two work methods are also included to help children improve the lingering problem:

the first is to set task timing; after a button on the top of the device is pressed, a voice setting task timing mode is entered; a task timing is set through a voice input mode, and timing is started after input is completed. When one task is completed, the main control chip control device responds correspondingly;

the second is task timing reminding; the remaining time of the task is informed, the reminding is performed when the time of the main control chip is one half or one fourth by default, and the self-defined setting can also be realized through voice; when the prompt is given, the prompt tone is sent out through the loudspeaker, and relevant action is made to prompt.

The appearance of the device is designed into a shell-breaking chicken for children, and the children are full of love and like small animals, so that the device is curious for life. Thus, the selection of lovely little yellow chicken as the appearance of children also shows the growth of a life. The device is vivid in design, so that the functions are full of interest. The invention comprises two stages: in the eggshell stage before shell breaking, the time cognition ability of the children is mainly improved, and the chicks break the shells and come out after the time cognition reaches a certain level. The broken chicken stage mainly aims at the problem of delay of children. The chicks will learn new skills while the child progresses and grow into spotted hens (the colour on the chicks will change). The following corresponding control method comprises two stages:

first, an eggshell stage. There are three modes that can be selected for this stage.

(1) And (7) identifying time. In the mode, a time is randomly displayed on the eggshell, the time is read after a child sees the time, and when the time is correctly read, the chicken can flap the wings, so that the chicken is said to be 'true-stick';

(2) stories and interactions between seconds/minutes/hour. The eggshell can explain the relationship among the three components by a way of telling a small story while shaking the body. Some questions can be given to the children to select, and the children select correct options through voice;

(3) count down each day. The base is provided with an aperture, and the number of the light emitted by the aperture lamp gradually decreases along with the time lapse. The next morning seven points later in time again changed back to all lights on.

Punishment measures are not set in each mode, children do not punish when mistake is made, but the eggshells give out error prompt tones. And if the answer is right, the hatching progress is increased, the hatching progress is displayed on the base, and the chick breaks the shell from the egg after the progress bar is full.

Then, chicken stage. There are also three modes that can be selected for this phase.

(1) And setting task timing. A task timing mode can be set through a voice input mode, and a chick cockscomb is pressed before voice input to enter a voice setting task timing mode;

(2) and (5) timing and reminding the task. The remaining time of the task is informed, the reminding is performed in half or one fourth of the time by default, and the setting can be customized. When prompting, a prompt sound is given, and wings are flapped to prompt;

When a task is completed, the chick beats the wings, saying "you are very young", and the feather color begins to change into a spotted hen. When the six tasks are completed, the hen will become a full-fleshed hen, and at this time a next simulated egg will fall from under the hen as part of an interesting interaction. If time out, one third of the feathers in the chicks turned back to the original yellow color. The accumulation is carried out for three times, and the spotted hens are changed back to the chicks.

The invention has the beneficial effects that: through the interesting interaction mode, the cognition of the children on the time is improved, the delayed behaviors of the children are reduced, and the good time concept is established when the children are young.

Detailed Description

The specific technical scheme of the invention is described by combining the embodiment.

Example 1

As shown in fig. 1 to 4, a schematic overall structure diagram of a novel method for improving time awareness of a child and an interaction device is provided, and the method for improving time awareness of a child includes the following steps:

comprises two stages: in the eggshell stage before shell breaking, the time cognition ability of the children is mainly improved, and the chicks break the shells and come out after the time cognition reaches a certain level. The broken chicken stage mainly aims at the problem of delay of children. The chicks will learn new skills while the child progresses and grow into spotted hens (the colour on the chicks will change).

The eggshell stage before shell breaking has three working modes, and the first mode is time recognition. The display screen is controlled by the main control chip to randomly display a time, and the voice recognition module is in a receiving state at the moment. When the sound of the child is detected and compared in the main control chip, and the result is accurate, the main control chip controls the motor to drive the wings of the chicken to swing up and down, and a loudspeaker is used for emitting encouraging sound of 'your real stick'.

The second is the story and interaction between seconds/min/hour. The main control chip controls the motor to enable an object connected with the motor to shift the center of gravity, and the eggshells are shaken after the left and right shifts. By reading the audio data in the SD card while shaking, a small story between seconds/min/hour is told to the child, and a small question is asked behind the story to let the child select, and the child selects the correct option by voice. The voice recognition module receives the voice and compares the voice with the result in the main control chip.

The third is a daily countdown. The base is provided with an aperture, the master control chip is used for timing, and a lamp is turned off after fixed time, so that the quantity of light emitted gradually decreases along with the lapse of time. When all the LED lamps are turned off, all the LED lamps are turned back to be on.

When interactive answering every time, the loudspeaker gives out an error prompt tone after the answer is wrong. And if the answer is right, the number of the bright LED hatching progress bars on the base is increased by one, and the chickens are shelled from the eggs after all the lights of the progress bars are bright.

The chicken stage after the shell breaking has three working modes, wherein the first mode is to set task timing. And pressing the cockscomb of the chicken to enter a voice setting task timing mode. A task timing is set through a voice input mode, and timing is started after input is completed. When one task is completed, the main control chip controls the motor to drive the wings of the chicken to swing up and down, and a loudspeaker is used for emitting encouraging sound of 'your real stick'. And controlling the color of the LED lamp on the chick body to enable the feather color to start to change into the spotted hen. When the counting reaches the six tasks, the color of the LED lamp is changed into a hen, and a next simulated egg falls from the lower part of the hen to be used as a part of interesting interaction. If time out, the LED lights go out, leaving the chicken yellow in color, and one third of the feathers on the chicken turn back to the original yellow color. The accumulation is carried out for three times, and the spotted hens are changed back to the chicks.

The second is task timing reminders. The remaining time of the task is informed, the reminding is carried out when the time of the main control chip is one half or one fourth by default, and the self-defined setting can also be realized through voice. During prompting, a prompt sound is sent out through the loudspeaker, and the motor drives the flapping wings to express promotion.

The interaction device for improving the time cognition of the children mainly comprises a voice recognition module, a key, a loudspeaker, a lithium battery, an LED lamp, a motor, a chip and the like. The keys, the LED lamps, the motor and the chips thereof comprise a plurality of groups, and each group has special functions.

The main control chip is responsible for receiving voice and key information, controlling work of LED devices such as feathers, diaphragms and progress bars, and enabling the chicken to flap wings and shake bodies by controlling different motors. The main control chip selects an STM32F103C8 high-performance microcontroller which takes ARM Cortex-M3 as an inner core.

The microphone is a sound input device and converts sound signals into electric signals to be sent to the voice recognition chip.

The voice recognition chip adopts an LD3320 chip, integrates a voice recognition processor and some external circuits, and does not need to be externally connected with any auxiliary chip such as Flash, RAM and the like. Moreover, the identified keyword list can be edited dynamically at will, and the card content can be edited into the list in advance. For setting the speech recognition keyword: in the programming of the main control chip, the contents of the identification keywords such as 'hello' are dynamically transmitted into the chip by setting the register of the chip, and the chip can identify the set key words.

OLED display screen, because of space size limitations and functional requirements, a 0.96 inch white OLED display screen module was chosen for counting down of display events. And transmitting the program instructions of the displayed time, brightness, contrast and the like to the display screen through the main control chip. The power consumption is low, the resolution is 128 × 32, the SSD1306 is provided with a drive chip, and the I2C interface is used for communication.

The sound playing module is used for reading the story audio file stored in the memory chip and playing the story audio file through a loudspeaker. The memory chips are connected, the memory size is 64MByte, reading and writing are carried out through the SPI interface, and the bit rate is 128 kbps.

The motor and the driving chip thereof are divided into two groups which respectively act as:

(1) the body is shaken. The body of the chicken is shaken to pass through a long rod, the upper end of the chicken is connected with a small iron ball, and the lower end of the chicken is connected with a motor. When the motor turns left, the small iron ball is driven to incline left, so that the gravity center of the chicken shifts left; when the motor turns to the right, the small iron ball is driven to incline to the right, so that the gravity center of the chicken shifts to the right. The chicken is shaken by the left-right rotation of the motor. The schematic diagram is shown in fig. 5.

(2) Flapping the wings. The wings of the chicken are connected with the motor, and the wings of the chicken swing up and down through the left and right rotation of the motor.

The motor needs a motor driving chip for driving during working, the driving chip is L298N, the speed can be smoothly regulated through PWM pulse width, forward and reverse rotation can be realized, and overvoltage and overcurrent protection is realized. It is a high-voltage and large-current motor driving chip.

The LED lights are divided into three groups, respectively as feather color display, as hatching progress bars for daily countdown and eggshell mode. Wherein:

(1) displayed as feather color. Divided into red and orange LEDs. When the LED lamp of the part is not effective, the feather of the chicken is yellow, and the shell is semitransparent. When the LED lamp in the chicken is effective, the feather of the chicken shows the color change effect. One sixth feather of the whole body can change color every time the task is completed;

(2) as a daily countdown. The partial LED is an aperture that indicates the remaining proportion of the time of day. When the lamps are all on in one circle, the new day is indicated, and the LED aperture is gradually extinguished as the time goes. The children are helped to establish a better day and time concept, and the concept of time conservation is promoted;

(3) hatching progress bar in eggshell mode. The partial LEDs are progress bars with one grid for indicating the hatching progress of the current chicks and encouraging the children to better participate in the game of cognitive time.

The power module is responsible for providing stable voltage and current and realizing voltage conversion, and selects and uses the chip LM 1117-3.3. The input voltage of the power supply module is 3.7V, and the output voltage of the power supply module is 3.3V.

Example 2

As in fig. 6-8, the adjustable base and stand of fig. 6: the support is provided with a lifting key, and the height of the adjustable support can be adjusted by pressing the lifting key and pulling up the lifting key. When the bracket is not used, the height can be reduced to shrink the bracket, so that the bracket is convenient to store.

Cracking of the eggshell: the hatched egg shell is split into 4 pieces, and the egg shells are still connected to the egg tray, so that the chicks can be hatched repeatedly.

Pressing a key: the cockscomb on the small cockhead is a voice input key, and the base is provided with a mode switching key.

After the shell is broken, the chicken is lifted by high altitude, and the chicken can be detached after the skills of the chicken are completely learned. If the chick returns to the shell breaking stage due to multiple times of delays, the chick descends, and the eggshell shrinks.

Every time a task is fulfilled on time, a part of the color film turns over to be changed into the color of the back surface of the color film (the hen flower feather). When the six tasks are completed, the hen becomes a spotted hen completely, and a next simulated egg falls from an egg outlet below the spotted hen at the moment as part of interesting interaction. After the eggshells are returned to the chicken body, the chicken returns to the initial state. The simulated eggs need to be put into an up-and-down sliding door at the back of the chicks.
