Description

GAME DEVICE USING BRAIN WAVES AND GAMING METHOD

An electrical potential difference of several tens of micro volts at a frequencyless than 30Hz and measured from the skin of the human head is a physical value reflecting the state of consciousness and highly valuable in the fields of science and technology As one technological application, a device control technology using only thinking of a human being is being studied so that a device recognizes the will of the human being directly When a human being is in a psychologically stable state or closes his or her eyes, alpha waves of 8-13Hz are dominant In the stable state or when there are no thoughts, beta waves of 13-30Hz decrease
In the prior art, a mind switch was disclosed, in which the change in alpha waves due to opening and closing of the eyes of a human being is used, so that only thinking operates a device, turns on or off an electric bulb, or manipulates a toy simply Also, the fact that the intensity of the brain waves decrease in the stable state is used, so that a racing match game apparatus uses only a thinking as its on-and-off control signal If a human being closes his or her eyes to rest, a positiveness/negativeness (on/off) can be easily recognized since the change in brain waves fluctuates greatly However, even when a human being does not close his or her eyes, the recognition ratio for a one-bit mental discrimination such as the on/off discrimination is very high, and the recognition ratio further increases through practice Also, an eye tracker was proposed in which a cursor on a computer monitor can be moved in accordance with what a user looks at by tracking the movement of the user's eye balls U S Patent No 5,638,825 was issued as an example of the prior art relevant to the above cursor movement
Since the above existing control methods using brain waves adopt brain wave recognition irrespective of the difference in brain waves of each person, an analytical error can occur due to the individual difference in brain waves of the human being Also, since each individual brain wave is not compared with a brain wave database comprised of statistical values, a frequency domain which can be easily controlled by each person, or an individual concentration capability cannot be effectively used Further, there exists no technology for changing the situation of a game picture by measuring brain waves

The circuit of the converter 2, as shown in FIG 2, includes an amplifier 22 which receives a head band electrode signal of several micro volts and amplifies it fifty thousand times, an analog to digital converter 24 for converting the amplified analog signal into a digital signal, and a computer interface for converting the digital signal from the analog to digital converter 24 into a signal being input to a computer serial port The computer 3 analyzes the brain wave signal which has been measured and input to the computer 3 and extracts several parameters from it In the present invention, amplitudes, average values and standard deviations of an alpha wave and a beta wave among the brain waves measured at the left and right frontal lobes of the brain, and a ratio of the alpha and beta waves are used as parameters The analysis method for extracting the measuring positions of the brain waves, the frequency and the parameters are varied appropriately according to the purpose and the type of game In order for a gamer to become more advantageous in the game as the stability of the user becomes higher, the ratio of the alpha waves and beta waves is chiefly used as a parameter The parameters of the brain waves used for producing a game control command language are called control variables In order to discriminate the state or will of the user by using the brain wave control variables, a reference value of each variable is required For example, if a variable X becomes larger than a reference value Xg, an object on the computer monitor rises up, otherwise the object falls down Here, there are cases of obtaining it in real-time and by using a database as the method of determining the reference value XQ
In the case that the reference value is determined in real-time, the brain waves need not be measured in advance and the brain wave signal measured in real-time are statistically analyzed, for example, frequency-analyzed to determine a reference value For example, an average value of an alpha wave ratio from a game start time to a current time is determined as a reference value If an alpha wave ratio higher than the reference value is measured, it is determined that the user is in a stable state
In the case that a database is used, the brain waves of the user are measured in advance and then a reference value appropriate for the brain waves of the user is input from the database When the user starts to enjoy the game, he or she registers his or her own brain waves through measurement of the brain waves After his or her own brain waves have been registered, the registered values are used The database includes reference values of the variables appropriate for the individual features of the brain waves according to the statistical analysis result with respect to the brain waves of several persons

In the case that two or more variables are used, a command word is produced by using a value obtained by adding each value obtained by multiplying ΔS, according to each variable Xi by a weight value Wi as in the following Equation 2
AS = X W1AS1 (2)

FIG 4 is a flowchart showing a case in which a database is used, among operation methods of a game device using the brain waves according to the present invention This will be described below with reference to FIGs 1 , 2 and 4
If a user wears a head band 1 on the head and turns on a game device according to the present invention, a measured brain wave signal is input to a computer 3 (step 30) The computer 3 searches whether an input brain wave signal of a user is registered in a brain wave database stored in a memory or a hard disc therein (step 32) If it is judged that a user's brain wave pattern is not registered in step 34, brain waves are measured in a brain wave measurement mode (step 36) Then a reference brain wave value is obtained using the measured brain waves or the user registration information (step 38) If a reference brain wave value is obtained in step 38, the computer 3 proceeds to a game mode to then control an initial game screen to be displayed (step 40) Then, the computer 3 measures the current brain waves of the user (step 42) Then, the computer 3 compares the determined reference brain waves with the current measured brain waves, and determines the direction and velocity of animation, in order to control a game screen (step 44) Then, the computer 3 controls a picture animation to be displayed according to the determined game picture control amount (step 46) Then, the user determines whether he or she will continue or complete the game (step 48) If the user completes the game, the user information processed up to now is stored to then complete the game (step 50) If the user continues the game, the program proceeds to step 42, in which the current brain waves are measured to calculate a function and then control a picture animation in step 46 through a game control step 44
