Description

Electronic yut game system and method for determining a yut value

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention generally relates to an electronic shock game technology, and more particularly, provides an acceleration sensor and a transmitter / receiver within a physical ear finger, and based on a change in time of the acceleration value detected by the acceleration sensor according to the movement of the ear finger, respectively. Determination of the new type of electronic game system and its state value by combining the physical game and the software game by determining the surface type value of the chopsticks, collecting them from an external device, and determining the final game state value. It is about a method.

Conventionally, in the case of playing a game using ear games, the user first throws four ear fingers. Then, the user visually checks whether the top surface of the thrown toe is flat or spherical, that is, the face type value, and collects the four face type values to determine the state values such as degrees, dogs, hooks, pins, and hairs. After the decision, the horse placed on the board was applied to a moving game or play.

Recently, the computer has replaced the function of the physical ear to provide a random selection function. However, there is a demand for a technology that can combine the act of throwing the actual physical form and the software game that is executed in the computer because the game of playing the game using the computer has a limited entertainment effect.

In order to meet this demand, as a prior art, for example, the Republic of Korea Patent No. 10-0922384 has a built-in electronic device in the physical chopsticks to transmit the surface type value of the chopsticks after throwing the chopsticks by wireless transmission from the chopsticks to the horseboard It has been proposed that an electronic playing game device incorporating a wireless communication technology is used to display a voice.

According to such a prior art electronic weaning device, an optical sensor is provided in the ear. Accordingly, the electronic ear play apparatus determines the rollover state, that is, the surface type value of the ear tok, based on whether the light enters the optical sensor installed inside the ear. This type of electronic wetting device has limitations such that the electronic ear to be placed in a bright environment where light can enter, and that the play board on which the ear is placed should always be flat. In addition, additional components such as magnets are needed to ensure that the toe sticks to the play board and is fixed, as well as a separate vibration sensor to determine the moment when light begins to enter the light sensor after throwing the toe. There is a problem that the structure is complicated, the power consumption is high, and there is a high possibility of malfunction of the optical sensor according to the ambient environmental conditions because of the need for more.

Therefore, there is a technical demand in the technical field to which the present invention has to be able to detect a constant value irrespective of external environmental conditions while reducing the power consumption of the sensor and the circuit unit embedded in the electronic ear.

Sensors that can meet such demands are known as inertial sensors that detect inertial forces by accelerations acting on moving objects or acceleration sensors that detect changes in speed per unit time. These sensors have recently been miniaturized and low power consumption by applying MEMS (Micro Electro Mechanical System) technology, and have been developed as multi-axis sensors, and have optimal conditions that can be applied to electronic physics.

However, since the inertial or acceleration sensor has a very good detection sensitivity, for example, even when an object is held by a user, even a motion such as a slight hand shake is detected and thus malfunctions. An example of a technique for solving this problem by a software correction method in a circuit is described in Korean Patent No. 10-0940095, "Pointer movement value calculation device, pointer movement value correction method and posture angle variation correction method, and three-dimensional pointing device using the same. "Is disclosed in the registration publication. According to this, by correcting the detection value of the sensor for detecting the tilt of the pointer according to a specific algorithm executed by the processor, it is possible to prevent the accumulation of errors due to unnecessary detection values such as minute hand shake.

However, the conventional technique for compensating for minute hand shake of a hand holding a pointer is difficult to apply when throwing a hand-held toe, so it is difficult to apply the above technique to an electronic hand-playing as it is, and a new algorithm suitable for thrown toe movement is provided. need.

As a result of intensive research, the present inventors have detected the movement of the ear and determine the surface type value of the ear based on the detected value, and the determined surface type value is determined by a PC, a smartphone, a smart TV, or a tablet PC. In electronic shock system that transmits to an external device, the electronic chopsticks composed of the acceleration sensor with miniaturization and low power element, and a new algorithm to determine the face type value and the 윷 state value for the movement of the electronic chopsticks Led to develop.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. References cited in the present invention are incorporated herein by reference.

The electronic ear tom of an embodiment of the present invention is characterized in that it is possible to construct an easy to handle physical electronic toe by using an acceleration sensor, particularly an acceleration sensor employing a miniaturized and low power MEMS technology.

In addition, in one axis (Z-axis), the state of holding the physical toe of the stationary state by hand and starting to move, the state of the thrown toe dropping to the floor or hitting an object, and the state of falling or hitting the ear to stop are shown in one axis (Z axis). On the basis of the change width (that is, the displacement) of the acceleration value, it is characterized by detecting the overturning state of the ear, that is, whether the upper surface is a plane or a spherical surface. The detected rollover state, that is, the surface type value (plane or spherical surface) of the ear can be detected by, for example, a personal computer, a mobile internet device, a netbook, or a cell phone through a short range wireless communication method. It may be transmitted to an external device such as a phone, a smart phone, a smart TV, a general television, an IPTV (Internet Protocol Television), a tablet PC, or a personal digital assistant (PDA). The external device collects the surface type values received from the plurality of electronic fingers and visually displays them on a monitor or a built-in display, or uses game software that uses final final status values such as diagrams, dogs, hooks, bones, and hair. Can be used for

In general, games that run on personal computers, smart phones, smart TVs, tablet PCs, etc. will interface with the user in various ways. There are many ways to interface these games with the user, and among them, electronic fingers that generate various state values (degrees, dogs, girls, dogs, mothers) may be used as a way to induce interest in the game. Today's games implement 윷 play related software to drive virtual electronic chopsticks and use them as variables of the game, but from the user's point of view, they are less immersive and less interesting than traditional games that throw wooden chopsticks directly. do.

Accordingly, in view of the above, the present invention transmits a plurality of tongs, preferably four tongs, to a toot game, in which a horseboard and a horse are provided on a personal computer, a smart phone, a smart TV, or a tablet PC. By using the four electronic fingers and the acceleration sensor provided in each of them, the four overturning state (face type value) data of the four fingers are detected and transmitted, thereby providing a new interface between the game and the user.

First, as shown in FIG. 1, the electronic tongs 10 provided in accordance with one embodiment of the present invention, as in the form of a typical earpiece, have a plane 11b and a spherical surface 11a opposite thereto. It may have a main body 11 having an approximately semicircular cross section. (A) is a perspective view which shows the internal structure, (b) is the cross section cut by the Y-axis, (c) shows the cross section cut along the X-axis. The Z axis used in the specification of the present invention means an axis perpendicular to the spherical surface 11b and the plane 11a of the toe body 11.

As shown in FIG. 1, the electronic finger toe 10 may include an acceleration sensor 17, a battery 15, and a circuit board 13 in the center of the body 11. The circuit board 13 is preferably composed of a printed circuit board, and is located between the acceleration sensor 17 and the battery 15 at the center of the inner ear body 11.

The acceleration sensor 17 may be a sensor positioned in the center of the circuit board 13 and measuring acceleration values in three axes. In the present invention, the acceleration sensor 17 may use only an acceleration value of one of three axes, that is, Z axis.

As shown in the block diagram shown in FIG. 2, the acceleration sensor 17 located at the center on the circuit board 13 is connected to the control unit 131, and the control unit includes a battery 15 and a memory unit. 133 is connected to the transmission / reception unit 135 and the output unit 137 to control operations of the acceleration sensor 17, the memory unit 133, the transmission / reception unit 135, and the output unit 137.

The main body 11 is a rod having an elongated shape, such as the shape of a general ear, in the illustrated example, and has a shape in which one side is flat and the other is spherical, but is not limited to the shape as necessarily illustrated in the present invention. As long as the shape includes a plane and one spherical shape, the remaining sides do not matter what shape.

On the other hand, the battery 15 supplies power for the acceleration sensor 17 and the components on the circuit board 13 to operate.

The acceleration sensor 17 may be a sensor disposed on an inner center of the main body 11, that is, a sensor capable of sensing acceleration about three axes orthogonal to each other, that is, the X, Y, and Z axes, which are orthogonal to each other. For example, any sensor that can detect acceleration on the Z axis can be used. As the acceleration sensor 17 usable in the present invention, for example, a digital acceleration sensor manufactured by applying MEMS technology can be used.

For example, you can use an acceleration sensor from VTI Technologies' CMA3000-D01 model or an ADXL345 model from ANALOG DEVICES. The accelerometer of the CMA3000-D01 model can have a measuring range of ± 2g and ± 8g, and the accelerometer of the ADXL345 model can have a measuring range of ± 2g, ± 4g, ± 8g and ± 16g.

In one embodiment of the present invention, as an acceleration sensor, one having a measurement range of +/- 2g per axis can be used. On the other hand, if the acceleration sensor of ± 2g measurement range has a resolution of 10bit can be converted to 4g / 1024 resolution by the ADC, and if the resolution of 12bit can be converted to 4g / 4096 resolution by the ADC. However, the present invention is not limited to the above-described acceleration sensor, and of course, various acceleration sensors known in the art may be used.

The memory unit 133 stores the data sensed by the acceleration sensor 17, and includes criteria such as software commands necessary for the control unit 131 to operate, a threshold value for determining a motion state, or a threshold displacement for determining a peak detection state. Data values can be stored.

The transceiver 135 is capable of communicating with an external device through short-range wireless communication using wired or Bluetooth, wireless USB, Zigbee, Infrared Data Association (IrDA), Nordic, or SimliciTi. Means. As a communication protocol used in the wireless communication of the transceiver 135, for example, a communication protocol such as BT / Nordic / SimliciTI may be used. The external device 20 also includes a communication module using a communication protocol corresponding to the transceiver 135.

On the other hand, the short-range wireless communication device and / or communication protocol usable in the present invention is not limited to those described above, those skilled in the art to various short-range wireless communication device and / or communication protocols used in the art to which the present invention belongs. Of course, it can be applied.

The output unit 137 may include, for example, an LED (light emitting diode), a vibrator, a speaker, or the like, to visually or audibly display the operation state of the ear to the user.

The controller 131 controls the operation of the acceleration sensor 17, the memory unit 133, the transceiver 135, and the output unit 137, and according to the algorithm of the present invention, the overturning state of the ear, ie, the upper surface of the ear, is flat. Determines the face type value indicating whether or not a sphere is spherical. The controller 131 determines the movement of the ear and the surface type value based on the acceleration value with respect to the Z axis detected by the acceleration sensor 17 and the acceleration value change (ie, displacement) with time.

The movement of the torpedo determined by the controller 131 includes four different states, namely, a stop state, a peak detection state, a stop detection state, and an end state. The control unit 131 determines that the tong is thrown only when these four states are detected in succession and determines the surface type value.

The process of determining the surface type value in the electronic ear toe 10 by the electronic ear toe 10 of the embodiment having the above-described configuration and transmitting it to the external device 20 is illustrated in FIG. 3. . In FIG. 4, a process of determining the shock state value by summing four surface type values received from the external device 20 is illustrated.

Referring to FIGS. 3 and 4 together, the user drives the game to play in the external device 20, which may be, for example, his smartphone (S401), and waits for a start message (S402). In this state, for example, when a user grabs four electronic toes 10 by hand and throws them on the floor, the control unit 131 in each of the electronic toes 10 may display the acceleration detected by the acceleration sensor 17 for a predetermined unit time. For example, it checks at intervals of ns (nanoseconds) or microseconds (microseconds) and determines that it is in a stationary state (or idle state) if it does not exceed a predetermined threshold value, for example, 1 / 6g (S301).

Under the control of the controller 131, the acceleration sensor 17 reads an acceleration value in the X / Y / Z axis direction, in particular, an acceleration value in the Z axis direction (S302). If the readout acceleration value displacement exceeds the aforementioned threshold (e.g. 1 / 6g; approximately 10 DACs), the controller 131 determines the transition (i.e., there is movement) with the toe moving in a stationary state. (Corresponds to "Yes" in step S303). This may mean a state in which the user is about to throw a finger or hand, or immediately after the throw. On the other hand, if the readout of the acceleration value displacement is less than the threshold value (corresponding to "No" in step S303), it is determined as an idle state and the step S302 is repeated.

In the case of "Yes" in step S303, the control unit 131 controls the output unit 137 to notify the user of the start of detection, for example, by visually emitting the LED or generating a constant beep from the buzzer The user can be notified of the start of the game using the electronic game system. In addition, the controller 131 transmits a detection start message to the external device 20 through the transceiver 135 (step S304).

The initial detection start message transmitted in this manner is received by the external device 20 (corresponding to "YES" in step S403), and the time of receiving the initial detection start message is stored (step S404). Then, the external device 20 is in a waiting state for the start message until all of the detection start messages are received from the four electronic ears 10, for example (step S405), and the detection is performed from the four electronic fingers 10 in total. It is determined whether all start messages have been received (step S406).

When the receiving unit (not shown) of the external device 20 receives all of the detection start messages of the four electronic toes 10 (corresponding to "YES" in step S406), it is determined that the electronic tones are newly rolled and each electronic The surface type value data reception wait state from the toe 10 is in a state of being waited for (S408). At this time, it is checked whether all of the detection signals of four tones are received within a predetermined time (for example, 2 seconds) based on the reception time of the first received detection start message (step S406). Is not received (corresponding to No in step S406), it is checked whether the predetermined time has been exceeded (step S407). If the predetermined time has not been exceeded (corresponding to "No" in step S407), the process returns to step S405 again and is in a waiting state for the start message. If the predetermined time has been exceeded (corresponding to "yes" in step S407), S402 It returns to the step and is in the waiting state for the first start message again.

On the other hand, in the electronic tong 10, if "Yes" in step S303, the acceleration sensor 17 under the control of the control unit 131 continues to read the change over time of the acceleration value in the Z-axis direction (step S305), If the read acceleration value displacement exceeds a predetermined threshold displacement (eg, 1 g; approximately 70 DAC), the controller 131 determines that it is a peak detection state (or a high frequency vibration detection state) (corresponding to "Yes" in step S306). ). This may mean that the user threw the chopsticks so that they fell on the floor or hit the object. On the other hand, if the measured acceleration value displacement is less than the threshold displacement (corresponding to "No" in step S306), the acceleration sensor 17 under the control of the control unit 131 repeats the step S305 and the acceleration value of the acceleration value in the Z-axis direction is repeated. Continue reading changes over time.

Even after the peak detection, the acceleration sensor 17 continuously reads the time-dependent change of the acceleration value in the Z-axis direction under the control of the control unit 131 (step S307). The control unit 131 determines this as the detection of the stop state or the end state (corresponding to "Yes" in step S308), and if it is not below the threshold (corresponding to "No" in step S308), the control unit 131 performs the step S307. Repeatedly, the time-dependent change in the acceleration value in the Z-axis direction is periodically read out.

In the case of "Yes" in step S308, the control unit 131 determines that the tossing operation is finished and controls the output unit 137 to visually or audibly inform the user of the stopped state or the end state in which the toe movement is stopped. Can be delivered (step S309). The controller 131 determines the surface type value (the upper surface of the toe is flat or spherical) based on the acceleration value detected in the stop state or the end state, and transmits the determined surface type value through the transceiver 135. Transmitting to the external device 20 (step S310).

For example, in the memory unit 133, a plane type value determined according to which of the direction of the stopped toe-top surface corresponds to + Z or -Z is stored in advance. The controller 131 determines a top direction (+ Z or -Z) of the stopped ear, based on the acceleration value detected with respect to the Z axis in the stop state or the end state, and corresponds to the prestored in the memory unit 133. The surface type value (for example, a flat surface when the upper surface is in the + Z direction or a curved surface when the upper surface is in the -Z direction) is read and determined.

Each of the four electronic fingers 10 transmits the determined surface type value data to the external device 20 (step S310), and as shown in FIG. 4, a total of four at the receiver (not shown) of the external device 20 is shown. It is checked whether or not all of the surface type value data is received from the four electronic fingers 10 (step S409). At this time, it is checked whether all of the four kinds of surface type value data have been received within a predetermined time (for example, two seconds) after receiving the first surface type value data (step S409). If not (corresponding to No in step S409), it is checked whether the predetermined time has been exceeded (step S410). If the predetermined time has not been exceeded (corresponding to "No" in step S410), the process returns to step S408 and the surface type data reception state is in standby state. If the predetermined time is exceeded (corresponding to "Yes" in step S410). In step S402, the process returns to the initial start message waiting state.

In addition, in order to ensure that the surface type value data received from the plurality of electronic fingers 10 is derived from the distinct electronic fingers 10, each electronic fingers 10 differs from each other in addition to its own surface type values. Unique identification information or distinguishing information that can be distinguished from the electronic chopstick 10 may also be transmitted to the external device 20.

On the other hand, when all of the face type value data is received in step S409 (corresponding to "YES" in step S409), these face type values are collected to determine the shock state value (step S411). That is, when all four surface type value data are received from the external device 20 (corresponding to "YES" in step S409), the software for playing on the external device 20 collects these surface type values to obtain the state. The value may be determined by determining and determining the value, and may be displayed on the screen or provided to be used by another game program to be executed (step S411).

FIG. 5 is a graph illustrating a relationship between a change in acceleration value over time and each detection step in a process of detecting a surface type value caused by each movement of an electronic ear toe according to an embodiment of the present invention. In the graph of FIG. 5, the detected accelerations for each of the three axes of X, Y, and Z are indicated by curves of different colors. Although the acceleration values detected in the X, Y, and Z axes are described in the illustrated example, it will be understood by those skilled in the art that the present invention requires only data on the Z axis.

In the example of FIG. 5, the unit axis having a length of about 1/30 second as the time axis is indicated as the number (1-246). In addition, the vertical axis represents an acceleration value in the range of ± 200 DAC (digital acceleration), where 10 DAC corresponds to approximately 1 / 6g (DAC value is converted when the measurement range of the acceleration sensor is ± 2g and 8-bit resolution). ). In the present specification, g denotes the acceleration of gravity.

Looking at the change in the acceleration value with time shown in Figure 5 can be divided into four chopsticks state on the basis of the time axis.

The first state is the stop (idle) state (time axis unit time [1:15]), and it can be seen that there is almost no change in the 3-axis acceleration sensor value. This state is the state before the movement of the ear is detected. The transition state from the stop state to the moving state (that is, the movement) may be determined by the threshold stored in the memory unit 133. The controller 131 maintains the average value of the accelerations detected by the acceleration sensor 17 in the memory unit 133, and periodically controls the acceleration sensor 17 to check the acceleration value. If the acceleration mean value displacement exceeds a threshold (e.g. 10-DAC; approximately 1 / 6g) and the exceeded acceleration mean value displacement is maintained for a period of time (e.g. 1 second) It can be determined that the toe has moved from a stationary state to a moving state.

The second state is the peak detection state (time base unit time [16: 156]). The transitioned state from the stationary state is a case where the 3-axis acceleration sensor value displacement exceeds the threshold, and from this time, the transition is made to the peak detection state. In this state, a high frequency component (that is, a phenomenon in which the acceleration value displacement is suddenly shown with time) as shown in the time axis unit time [136: 156] of FIG. 5 is detected. This high frequency component has a frequency component of several tens of Hz (for example, 10 to 30 Hz) due to the rapid change in acceleration value when the toe falls on the floor or hits an object, and its amplitude is 1 g or more (approximately 70 DAC). Appears as Accordingly, a cut-off frequency of a high pass filter, which is additionally provided to the circuit board 13 of the electronic ear toe 10 of the present invention or may be included as a single chip in the acceleration sensor, is applied to the corresponding high frequency frequency. If set, the controller 131 determines that the peak detection is performed when the amplitude of the extracted frequency component is equal to or greater than a threshold displacement (for example, 1 g) stored in the memory unit 133. After the peak is detected, the controller 131 transitions to the stop detection state in consideration of a phenomenon in which the ear is naturally 'stopped'.

Therefore, the third state becomes the stop detection state (time axis unit time [156: 171]). In this state, the acceleration sensor 17 detects that all of the acceleration value displacements of the three-axis acceleration sensor fall below the above-described threshold (for example, 10-DAC). If all of the acceleration value displacements of the three axes detected by the acceleration sensor 17 are equal to or less than the above-described threshold value, the controller 131 transitions to the end state in consideration of the phenomenon in which the ear is gradually stopped.

Therefore, the fourth state becomes the end state (time axis unit time [171: 246]). In this state, the acceleration sensor 17 under the control of the controller 131 detects whether the acceleration value displacement dropped below or below the threshold is maintained for a predetermined time (for example, 3 seconds). If it is determined that the end state, among the acceleration values of the acceleration sensor 17, the acceleration value of the Z-axis is read. In the example of FIG. 5, since the acceleration value of the Z axis in the end state is about -1 g (approximately -48 DAC), the controller 131 determines that the upper surface of the current finger is the + Z axis and thus, the plane type value is "plane". And inform the external device 20.

That is, the memory unit 133 prestores "a surface type value which is determined according to which the direction of the stopped ear top surface corresponds to + Z or -Z." The controller 131 determines the Z-axis direction (+ Z or -Z) of the upper surface of the torpedo according to the acceleration value of the acceleration sensor 17, and uses the data of the memory unit 133 to determine the Z axis of the upper torpedo surface. The surface type value according to the direction is determined (for example, a flat surface when the upper surface is in the + Z direction or a curved surface when the upper surface is in the -Z direction).

For example, the memory unit 133 stores the surface type value of the top surface of the torpedo stopped according to the Z axis acceleration value of the acceleration sensor 17 as follows, and the controller 131 stores the data of the memory unit 133 as follows. And according to the Z axis acceleration value of the acceleration sensor 17, it is possible to determine whether the top surface of the toe is a plane or a spherical surface:

- next -

상 top surface is flat: gravity direction is -Z axis direction, in this case acceleration value of Z axis acceleration sensor is -1g;

윷 Spherical top surface: Gravity direction is + Z axis, in this case, acceleration value of Z axis acceleration sensor is + 1g.

On the other hand, according to the process shown in Figure 4 from the surface type values received from the four electronic chopsticks 10 to determine the state value shown in Table 1 below. At this time, if all four surface type value data have not been received within a certain time (for example, 2 seconds) after receiving the first surface type value data, the user is regarded as an indeterminable state value and the user throws the tomb again. (See step S409 in FIG. 4).
