Referring to FIG. 1, the portable terminal may include a control unit 100, a sound control unit 102, a memory unit 108, an input unit 110, a display unit 112, and a communication unit 114. The sound adjusting unit 102 may further include an object checking unit 104 and a collision amount calculating unit 106.

First, the controller 100 of the portable terminal controls the overall operation of the portable terminal. For example, the processor 100 performs processing and control for voice call and data communication, and in addition to the usual function, the controller 100 may realistically output the sound generated when executing the motion UI according to the characteristics of the object. Process.

That is, the controller 100 of the portable terminal provides a sound by applying characteristics such as the material and shape of the object being output instead of the sound of the same pattern when a sound is generated due to the collision between the objects being output. Handle to provide the same effect as crashing.

The sound control unit 102 is controlled by the control unit 100 to provide a sound that reflects the characteristics of an object in order to provide a realistic sound, that is, a sound generated by a collision of an actual object, instead of a sound of the same pattern. do.

In order to provide the above effects, the sound control unit 102 processes the object identification unit 104 to check the characteristics of the object being output on the display unit 112 of the portable terminal, and the collision amount calculation unit ( 106) to calculate the collision amount of the object.

Thereafter, the sound control unit 102 reflects the characteristics of the object in the collision amount calculated by the collision amount calculation unit 106 and checks the position where the collided object is to be located, and then the sound corresponding to the object of the corresponding position. Treat to adjust.

The object checking unit 104 checks the characteristics of the object being output, that is, the material, shape, size, etc. of the output object under the control of the sound adjusting unit 102, and provides the object to the sound adjusting unit 102. When a collision between the output objects occurs, the collision amount calculator 106 calculates a collision amount of the collided object and provides it to the sound controller 102.

The memory unit 108 of the portable terminal includes a read only memory (ROM), a random access memory (RAM), and a flash ROM. The ROM stores microcodes and various reference data of a program for processing and controlling the controller 100 and the sound controller 102.

The RAM is a working memory of the controller 100, and stores temporary data generated during execution of various programs. In addition, the flash ROM stores various updatable storage data such as a phone book, an outgoing message, a received message, and information of a user's touch input point.

For example, the controller 100 may be configured to process all of them.

In the above description, the apparatus for adjusting the sound generated according to the position, material, and shape of the object in order to realistically provide the sound generated when the motion UI is executed in the portable terminal according to the characteristics of the object has been described. A method of generating realistic sound when executing a motion UI using the apparatus according to an exemplary embodiment will be described.

2 is a flowchart illustrating a process of adjusting a volume of a sound generated when a motion UI is executed in a portable terminal according to the present invention.

Referring to FIG. 2, the portable terminal first checks whether a motion UI execution event occurs in step 201. Here, the motion UI execution event refers to an event for executing an additional function using a motion detector, such as a beat box function and a dice function.

If it is determined in step 201 that the motion UI execution event does not occur, the portable terminal proceeds to step 213 to perform a corresponding function (eg, standby mode).

On the other hand, if it is determined in step 201 that the motion UI execution event occurs, the portable terminal proceeds to step 203 and checks the object displayed on the screen according to the additional function executed by the user of the portable terminal.

For example, when a user of the portable terminal wants to execute a dice function, the portable terminal may process to output a plurality of dice objects on the screen.

In step 205, the portable terminal processes to determine the characteristics of the object being output. Here, the characteristics of the object being output means the material (eg, wood, glass, iron, paper, etc.), shape (eg, square, hexagon, cylinder, etc.), size, etc. of the object. It is to grasp the characteristics of the object in order to output different sounds generated by the collision between objects using different sound waveforms that react upon collision according to the characteristics of the object.

In step 207, the portable terminal determines whether a collision occurs between objects being output on the screen of the portable terminal. This is to confirm whether the user of the portable terminal performs an operation to move the object, such as to shake the portable terminal.

If it is determined in step 207 that there is no collision between the objects being output on the screen of the portable terminal, the portable terminal proceeds to step 207 and reconfirms whether collisions between objects being output on the screen of the portable terminal occur.

On the other hand, if it is determined in step 207 that a collision occurs between the objects being output on the screen of the portable terminal, the portable terminal proceeds to step 209 to process the object to calculate the collision amount. At this time, when calculating the amount of collision between the objects, the portable terminal processes to calculate the amount of collision reflecting the characteristics of the object.

That is, the portable terminal may generate a sound that changes according to the material of the object by calculating a collision amount by applying a constant according to the material of the object when calculating the collision amount of the object.

Thereafter, the portable terminal proceeds to step 211 to process the sound corresponding to the object according to the collision amount calculated in step 209.

The portable terminal then terminates this algorithm.

3 is a flowchart illustrating a process of adjusting a sound volume generated when executing a motion UI in a portable terminal according to an exemplary embodiment of the present invention.

Referring to FIG. 3, the portable terminal first checks whether a motion UI execution event occurs in step 301. Herein, the motion UI execution event refers to an event for executing an additional function using a motion detector, such as a beat box function and a dice function, as described above.

If it is determined in step 301 that the motion UI execution event does not occur, the portable terminal proceeds to step 321 to perform a corresponding function (eg, a standby mode).

On the other hand, if it is determined in step 301 that the motion UI execution event occurs, the portable terminal proceeds to step 303 and checks the object output on the screen according to the additional function executed by the user of the portable terminal. In FIG. 3, assuming that a user of the portable terminal executes a dice function, the portable terminal may process to output a plurality of dice objects to a screen.

Thereafter, the portable terminal proceeds to step 305 to determine the material of the object being output, and then proceeds to step 307 to determine the shape of the object being output. In other words, the steps 305 and 307 are to determine the characteristics of the object being output, it is also possible to determine the characteristics of the additional object (for example, the size of the object) in addition to the material and shape.

In step 309, the portable terminal determines whether a collision occurs between objects being output on the screen of the portable terminal. This is to confirm whether the user of the portable terminal performs an operation to move the object, such as to shake the portable terminal.

If it is determined in step 309 that there is no collision between the objects being output on the screen of the portable terminal, the portable terminal proceeds to step 309 and reconfirms whether collisions between objects being output on the screen of the portable terminal occur.

On the other hand, if it is determined in step 309 that there is a collision between the objects being output on the screen of the portable terminal, the portable terminal proceeds to step 311 to calculate the collision amount according to the object collision. Here, the collision amount means a force acted for a very short time such as a force acting on a bullet fired from a gun, a force acting when two objects collide, such as when kicking a soccer ball or batting a baseball.

In this case, the portable terminal may calculate the collision amount using Equation 1 below.

Here, F is the impact force, m is the mass, t is the time, v is the speed, the number 1 is the moment just before the impact, the number 2 means the moment immediately after the impact.

In step 313, the portable terminal processes the material of the object to be reflected in the impulse calculated in step 311.

Here, step 313 is to determine the position after the collision of the object through the collision amount according to the characteristics of the object, it can be calculated using the following equation (2).

Here, F is the impact force, m is the mass, t is the time, v is the speed, the number 1 is the moment just before the impact, the number 2 means the moment immediately after the impact. In addition, the c means a constant value for the object material, it means that the constant value for the characteristics of the object is reflected in the collision amount calculated by the equation (1).

In step 315, the portable terminal determines the location of the collided object. In step 317, the portable terminal calculates a sound control value according to the location of the collided object.

That is, when the steel object collides, the portable terminal will determine that the object will be located at a short distance after the collision, and the glass object will be determined to be located farther than the steel object. In this case, the portable terminal may calculate the motion of the object using an Ordinary Differential Equation. In this case, Euler Method, Improved Euler Method, and Runge-Kutta 4th order method based on Taylor equation are used to calculate the ordinary differential equation.

The Euler method is lower than the Runge-Kutta method in numerical accuracy, considering only the first derivative by the Taylor series, given the initial conditions and equations. However, the Euler method shows the best performance among the three methods in terms of computational speed. .

The Improved Euler Method considers up to the second derivative in the Taylor series, and the Runge-Kutta-4 Method considers up to the fourth derivative in the Taylor series and shows the best performance in the accuracy of the calculations compared to the Euler Method. Accordingly, the portable terminal calculates the location of the object using the Euler method for the object determined to be located at a long distance, and uses the Runge-Kutta-4 method for the object determined to be located at a close distance. Accurately calculate the position of the object.

The portable terminal that calculates the position of the object is processed to reduce the sound generated by the object located at a long distance and to raise the sound generated by the object located at a close distance, so that the user hears a sound such as the sound generated by the collision of the actual object. Provide it.

In step 319, the portable terminal processes the sound control value calculated in step 317 to be applied to the sound generated by the object, and then terminates the algorithm.

The portable terminal then terminates this algorithm.

In FIG. 3, the collision amount of all objects output from the portable terminal is calculated at one time, but the portable terminal calculates the collision amount with respect to one object and then calculates the collision amount with respect to another object with respect to all objects. Can be done.
