Description

Electronic Dice and How to Determine the Dice

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to electronic dice technology, and more particularly, to provide an acceleration sensor and a transceiver in a physical polyhedral dice, based on a time-based change in the acceleration value detected by the acceleration sensor as the dice move. The present invention relates to a new electronic dice and a method for determining the dice value, by which a dice value can be determined and transmitted to an external device, so that a physical dice game and a software game can be combined.

When playing a game using a conventional dice, the user first throws the dice. Then, the user visually checks the number of the top or number of dice thrown as a dice value, and applies the dice value to a game or play.

In recent years, the physical dice function has been replaced by a computer to provide a random selection function. However, since the dice game using a computer has limited entertainment effects, there has been a demand for a technology capable of combining the actual physical form of the dice throwing and the software game played in the computer.

In order to meet such a demand, an electronic dice that can transmit a dice value after throwing a dice by embedding an electronic device in a physical dice have been proposed.

For example, Korean Patent Laid-Open Publication No. 10-2006-0000802 discloses a method of automatically determining the number of electronic dice and dice and an external device control unit controlled by the dice. And an electronic die provided with a light emitting device and a circuit portion are described. According to the conventional technology, when the electronic dice are thrown on a certain bottom surface, the electronic circuitry inside the electronic dice finds the face of the dice that is closest to the bottom face and automatically identifies the number or number of points on the top of the dice. In this case, the identified signal is wirelessly transmitted to the outside. However, the prior art has a problem that the infrared sensors are installed on each side of the cube dice, and the structure is complicated, power consumption is high, and there is a high possibility of malfunction of the infrared sensor according to the ambient environmental conditions.

Therefore, there is a technical demand in the technical field to which the present invention should 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 die. 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 dice.

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 such a problem by a software correction method in a circuit is disclosed in Korean Patent No. 10-0940095, "Pointer Movement Value Calculation Device, Pointer Movement Value Correction Method, and Posture Angle Variation Correction Method, 3D 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 the slight shaking of the hand holding the pointer is difficult to apply when throwing a hand-held dice. Therefore, it is difficult to apply the above technique to an electronic dice as it is. need.

Accordingly, the present inventors have made intensive studies, and as a result of the miniaturization and low-power device of the electronic dice of detecting the movement of the dice, determining the dice value based on the detected values, and transmitting the determined dice value to an external device. It has led to the development of electronic dice constructed using accelerometers and new algorithms to determine dice values appropriate to the movement of these electronic dice.

From the detailed description and examples of the present invention, those skilled in the art to which the present invention pertains can easily be interpreted as belonging to the scope of the present invention. References cited in the present invention are incorporated herein by reference.

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

In addition, the acceleration range of three axes can be changed by holding a stationary physical dice by hand and starting to move, the throwing dice falling to the ground or hitting an object, and the falling or hitting dice stopping. It is characterized by detecting a dice value based on (i.e., displacement). The detected dice value may be, for example, a personal computer, a mobile internet device, a netbook, a cell phone, a smart phone, or a smart TV through a short range wireless communication method. Can be transmitted to an external device such as a regular TV, an IPTV (Internet Protocol Television), or a personal digital assistant (PDA). These external devices may be running game software using the dice value.

In general, games that run on personal computers, smart phones, smart TVs, etc. will interface with the user in various ways. There are many ways to interface these games with the user, and among them, dice that generate various random numbers are used as a way to induce interest in the game. Current games implement dice software to drive virtual dice and use one selected number as a variable of the game, but from the user's point of view, the traditional method of rolling physical dice may be preferred.

Accordingly, in view of the above, the present invention provides an electronic dice for transmitting dice values to a game running on a personal computer, a smart phone, and a smart TV, that is, a game using a polyhedral electronic dice that detects numbers using an acceleration sensor. Provide a new interface between users.

First, as shown in Figure 1, the electronic dice 10 provided according to an embodiment of the present invention is an acceleration sensor 17, a battery 15, a circuit board 13 inside the cube-shaped main body 11 ) May be included. The circuit board 13 is preferably composed of a printed circuit board. In the center of the dice body 11, two circuit boards 13 are disposed above and below the battery 15 with the electronic dice 10 disposed therebetween. Will be able to grasp the center of gravity. In addition, the acceleration sensor 17 is positioned at the center of the circuit board 13 to measure acceleration values in three axes.

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 cube in the illustrated example, but of course it is not necessarily limited to the cube in the present invention. That is, it can be used if it is a regular polyhedron shape including an outer surface made of surfaces of the same shape. For example, the body 11 may be formed of a tetrahedron, a cube, an octahedron, a tetrahedron, a tetrahedron, or the like. 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 is a sensor disposed on an inner center of the main body 11, that is, a center of gravity, and capable of detecting accelerations on three axes orthogonal to each other, that is, the X, Y, and Z axes. As the acceleration sensor 17 usable in the present invention, for example, a three-axis 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 for each axis may 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.

In the example shown in FIG. 1, the circuit board 13 is disposed above and below the battery 15, which is used to symmetrically distribute the weight, and an acceleration sensor in which the overall weight distribution of the electron dice 10 is disposed at the center. This is to distribute circularly symmetrically about (17).

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. 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 an LED (light emitting diode), a vibrator, a speaker, or the like to visually or audibly display the operation state of the dice to the user.

The controller 131 determines the dice value according to the algorithm of the present invention while controlling the operations of the acceleration sensor 17, the memory unit 133, the transceiver 135, and the output unit 137. The controller 131 determines the movement of the dice and determines the dice value based on the acceleration values for each of the three axes detected by the acceleration sensor 17 and the acceleration value change (ie, displacement) over time.

The movement of the dice 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 controller 131 determines that the dice are thrown only when these four states are detected in succession and determines the dice value.

3 illustrates a method of determining a dice value by an electronic dice 10 according to an embodiment of the present invention having the configuration as described above.

Referring to FIG. 3, when the user grabs the electronic dice 10 by hand and throws it on the floor, the controller 131 may determine the acceleration detected by the acceleration sensor 17 for a predetermined unit time such as ns (nanoseconds) or ㎲ ( Microseconds), and if it does not exceed a predetermined threshold, for example, 1 / 6g, it is determined that the stationary state (or idle state) (S301).

Under the control of the control unit 131, the acceleration sensor 17 reads acceleration values in three axial directions of X, Y, and Z (S302), and the read acceleration value displacement is equal to the aforementioned threshold (e.g., 1 / 6g; approximately 10 DACs). If more than), the control unit 131 determines the transition (that is, there is movement) to the state in which the dice move from the stationary state (corresponding to "Yes" in step S303). This may mean a state in which the user is about to throw the dice by 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, under the control of the control unit 131, the acceleration sensor 17 reads a change over time of acceleration values in the three-axis directions of X, Y, and Z (S304), and the read acceleration If the value displacement exceeds a predetermined threshold displacement (for example, 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 S305). This may mean that the user dropped the dice and the dice fell to the floor or hit the object. On the other hand, if the read acceleration value displacement is less than the threshold displacement (corresponding to "No" in step S305), while repeating step S304, the acceleration sensor 17 under the control of the control unit 131, the three axes of X, Y, Z Continue reading the change over time of the acceleration value in the direction.

When a peak (high frequency vibration) is detected, the controller 131 may control the output unit 137 to visually or audibly transmit the state of the dice, that is, the start of detection for determining the number of the dice, to the user (S306). ). For example, the LED can visually emit light or generate a constant beep from the buzzer to alert the user to the start of a dice game.

Subsequently, under the control of the controller 131, the acceleration sensor 17 periodically reads a change according to time of acceleration values in three axes of X, Y, and Z (S307), while the acceleration value displacement is for a predetermined time. When the threshold value is lower than the above-described threshold, the control unit 131 determines this as the detection of the stop state or the end state (corresponding to "YES" in step S308), and when it is not below the threshold (corresponding to "No" in step S308). The step S307 is repeated to continuously read the change over time of the acceleration values in the three-axis directions of X, Y, and Z periodically.

In the case of "Yes" in step S308, the controller 131 determines that the dice rolling operation is finished and controls the output unit 137 to visually or audibly inform the user of the stop state or the end state in which the dice movement is stopped. Can be delivered (S309). Then, the controller 131 determines the dice value (number) based on the acceleration value detected in the stop state or the end state, and transmits the determined dice value to the external device through the transceiver 135 (S310). ).

For example, the memory unit 133 pre-stores the dice number which is determined according to which one of the direction of the stopped dice upper surface corresponds to ± X, ± Y or ± Z. The controller 131 determines the top direction of the stopped dice based on the acceleration values detected for the three axes of X, Y, and Z in the stop state or the end state, and the " stop " The dice value is determined by reading the dice number determined according to whether the direction of the top of the dice is ± X, ± Y or ± Z.

4 is a graph showing a relationship between a change in an acceleration value over time and each detection step in a method of detecting a dice value by detecting a movement of an electronic dice according to an embodiment of the present invention. In the graph of FIG. 4, the detected accelerations for each of the three axes of X, Y, and Z are indicated by curves of different colors. In the example of FIG. 4, 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 ± 150 DAC (digital acceleration), and 10 DAC corresponds to approximately 1 / 6g (DAC value is converted when the acceleration sensor has a measurement range of ± 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 4 can be distinguished four dice 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 before the dice movement 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 die has transitioned from the stopped 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. 4 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 dice fall to the ground or hit an object, and its amplitude is 1 g or more (approximately 70 DAC). Appears as Therefore, a cut-off frequency of a high pass filter, which is additionally provided on the circuit board 13 of the electronic dice 10 of the present invention or may be included as a one-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 dice naturally 'stop'.

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 that the dice are 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, the axis corresponding to, for example, ± 1g of the three-axis acceleration values of the acceleration sensor 17 is found. In the example of FIG. 4, since the acceleration value of the X axis in the end state is about -1g (approximately -48 DAC), the controller 131 determines that the upper surface of the current dice is + X axis, which is determined by the number "3". You will be informed.

That is, the memory unit 133 prestores the "dice number determined according to which of the stopped dice upper surface direction is ± X, ± Y, or ± Z". The controller 131 determines the dice value according to the axial direction according to the data of the memory unit 133 and the acceleration value of the acceleration sensor 17 and the dice upper surface direction.

For example, the memory unit 133 stores the number of the dice upper surface stopped along the axial direction according to the 3-axis acceleration value of the acceleration sensor 17 as follows, and the control unit 131 of the memory unit 133 The dice value can be determined according to the data and the axial direction according to the acceleration value of the acceleration sensor 17 and thus the dice top direction:

- next -

Dice number 1:-Z axis, in this case the acceleration value of the acceleration sensor of Z axis is -1g;

Dice number 6: + Z axis, in this case the acceleration value of the acceleration sensor of Z axis is + 1g;

Die number 3: -X axis, in this case the acceleration value of the acceleration sensor on the X axis is -1g;

Dice number 4: + X axis, in this case the acceleration value of the acceleration sensor on the X axis is + 1g;

Dice number 2: + Y axis, in this case the acceleration value of the Y-axis acceleration sensor is + 1g;

Dice number 5:-Y axis, in this case, the acceleration value of Y sensor is -1g.

On the other hand, the acceleration sensor value for the three axes in the end state and the number of the top surface of the electronic dice stopped after throwing can be determined in the same manner as described above, but this is an example of the die value of the top surface of the stationary dice It may be determined in various ways based on the acceleration value detected in the state.

As mentioned above, although this invention was demonstrated to the said Example, this invention is not limited to this. Those skilled in the art can make modifications and changes without departing from the spirit and scope of the present invention, and it will be appreciated that such modifications and changes also belong to the present invention.
